reginfo and secinfo location in sapmhairi black partner

Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Again when a remote server of a Registered Server Program is going to be shutdown due to maintenance it may de-register its program from the RFC Gateway to avoid errors. In case of TP Name this may not be applicable in some scenarios. Thus, if an explicit Deny rule exists and it matches the request being analyzed by the RFC Gateway, the RFC Gateway will deny the request. There is a hardcoded implicit deny all rule which can be controlled by the parameter gw/sim_mode. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. Specifically, it helps create secure ACL files. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. After reloading the file, it is necessary to de-register all registrations of the affected program, and re-register it again. RFC had issue in getting registered on DI. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Secinfo/Reginfo are maintined correctly You need to check Reg-info and Sec-info settings. When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Beachten Sie, da der SAP Patch Manager die Konfiguration Ihres SAP-Systems bercksichtigt und nur solche Support Packages in die Queue aufnimmt, die in Ihr System eingespielt werden drfen. It is important to mention that the Simulation Mode applies to the registration action only. The simulation mode is a feature which could help to initially create the ACLs. This means that the sequence of the rules is very important, especially when using general definitions. Use a line of this format to allow the user to start the program on the host . It is common to define this rule also in a custom reginfo file as the last rule. In the slides of the talk SAP Gateway to Heaven for example a scenario is outlined in which a SAProuter installed on the same server as the RFC Gateway could be utilized to proxy a connection to local. Part 6: RFC Gateway Logging For example: the system has the CI (hostname sapci) and two application instances (hostnames appsrv1 and appsrv2). Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. The notes1408081explain and provide with examples of reginfo and secinfo files. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo The Stand-alone RFC Gateway: As a dedicated RFC Gateway serving for various RFC clients or as an additional component which may be used to extend a SAP NW AS ABAP or AS Java system. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. Every attribute should be maintained as specific as possible. How to guard your SAP Gateway against unauthorized calls, Study shows SAP systems especially prone to insider attacks, Visit our Pathlock Germany website https://pathlock.com/de/, Visit our Pathlock Blog: https://pathlock.com/de/blog/, SAST SOLUTIONS: Now member of Pathlock Group. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_REG_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. In a pure Java system, one Gateway is sufficient for the whole system because the instances do not use RFC to communicate. Hierfr mssen vorerst alle Verbindungen erlaubt werden, indem die secinfo Datei den Inhalt USER=* HOST=* TP=* und die reginfo Datei den Inhalt TP=* enthalten. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . There are two different versions of the syntax for both files: Syntax version 1 does not enable programs to be explicitly forbidden from being started or registered. This means that if the file is changed and the new entries immediately activated, the servers already logged on will still have the old attributes. 3. Hint: For AS ABAP the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files) performs a syntax check. We made a change in the location of Reginfo and Secinfo file location we moved it to SYS directory and updated the profile parameter accordingly (instance profile). Trademark. Giving more details is not possible, unfortunately, due to security reasons. Somit knnen keine externe Programme genutzt werden. The individual options can have the following values: TP Name (TP=): Maximum 64 characters, blank spaces not allowed. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. The secinfosecurity file is used to prevent unauthorized launching of external programs. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. Alerting is not available for unauthorized users, Right click and copy the link to share this comment, Part 1: General questions about the RFC Gateway and RFC Gateway security, Part 8: OS command execution using sapxpg, Secure Server Communication in SAP Netweaver AS ABAP. This section contains information about the RFC Gateway ACLs, and examples of landscapes and rules.The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. The RFC library provides functions for closing registered programs. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. Successful and rejected registrations, and calls from registered programs can be ascertained using Gateway Logging with indicator S. Any error lines are put in the trace file dev_rd, and are not read in. Part 3: secinfo ACL in detail Part 8: OS command execution using sapxpg. This would cause "odd behaviors" with regards to the particular RFC destination. P means that the program is permitted to be registered (the same as a line with the old syntax). Visit SAP Support Portal's SAP Notes and KBA Search. Its location is defined by parameter 'gw/reg_info'. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. Wechseln Sie dazu auf die gewnschte Registerkarte (im Beispiel ist das Universen), whlen Sie Verwalten --> Sicherheit auf oberster Ebene --> Alle Universen (je nach Registerkarte unterscheidet sich der letzte Punkt). The local gateway where the program is registered always has access. Privacy | About this page This is a preview of a SAP Knowledge Base Article. The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. The related program alias can be found in column TP Name: We can verify if the functionality of these Registered RFC Server programs is accessible from the AS ABAP by looking for a TCP/IP connection in transaction SM59 with Technical Settings Activation Type = Registered Server Program the corresponding Program ID and either no Gateway Options or connection details to any of the RFC Gateways belonging to the same system set: Please note: If the AS ABAP system has more than one application servers and therefore also more than one RFC Gateways there may be scenarios in which the Registered Server Program is registered at one specific RFC Gateway only. For AS ABAP the ACLs should be maintained using the built-in ACL file editor of transaction SMGW (Goto Expert Functions External Security Maintain ACL Files). As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. The RFC Gateway does not perform any additional security checks. In case you dont want to use the keyword, each instance would need a specific rule. File reginfo controls the registration of external programs in the gateway. As i suspect it should have been registered from Reginfo file rather than OS. Each instance can have its own security files with its own rules. If the option is missing, this is equivalent to HOST=*. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. Die Datei kann vermutlich nicht zum Lesen geffnet werden, da sie zwischenzeitlich gelscht wurde, oder die Berechtigungen auf Betriebssystemebene unzureichend sind. We first registered it on the server it is defined (which was getting de-registered after a while so we registered it again through background command nohup *** & ), This solved the RFC communication on that Dialogue instance yet other Dialogue instances were not able to communicate on the RFC. Durch einen Doppelklick auf eine Zeile erhalten Sie detaillierte Informationen ber die Task- Typen auf den einzelnen Rechnern. so for me it should only be a warning/info-message. Somit knnen keine externe Programme genutzt werden. Environment. 2. All subsequent rules are not checked at all. In addition, note that the system checks the case of all keywords and only takes keywords into account if they are written in upper case. See the examples in the note1592493; 2)It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Part 3: secinfo ACL in detail. Read more. With secinfo file this corresponds to the name of the program on the operating system level. The default rules of reginfo and secinfo ACL (as mentioned in part 2 and part 3) are enabled if either profile parameter gw/acl_mode = 1 is set or if gw/reg_no_conn_info includes the value 16 in its bit mask, and if no custom ACLs are defined. Every line corresponds one rule. As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: Most of the cases this is the troublemaker (!) Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. It seems to me that the parameter is gw/acl_file instead of ms/acl_file. Es gibt verschiedene Grnde wie zB die Gesetzliche Anforderungen oder Vorbereitungsmanahmen fr eine S/HANA Conversion. There are various tools with different functions provided to administrators for working with security files. In other words, the SAP instance would run an operating system level command. How can I quickly migrate SAP custom code to S/4HANA? The RFC Gateway allows external RFC Server programs (also known as Registered Server or Registered Server Program) to register to itself and allows RFC clients to consume the functions offered by these programs. Part 2: reginfo ACL in detail. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. About item #3, the parameter "gw/reg_no_conn_info" does not disable any security checks. You can define the file path using profile parameters gw/sec_infoand gw/reg_info. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. Common examples are the program tp for transport management via STMS started on the RFC Gateway host of AS ABAP or the program gnetx.exe for the graphical screen painter started on the SAP GUI client host. Check the secinfo and reginfo files. This publication got considerable public attention as 10KBLAZE. Part 5: ACLs and the RFC Gateway security In other words, the SAP instance would run an operating system level command. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. Evaluate the Gateway log files and create ACL rules. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. We solved it by defining the RFC on MS. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. A rule defines. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. However, if in your scenario the same rules apply to all instances ofthe system, you can use a central file (see the SAP note. The reginfo file is holding rules controlling which remote servers (based on their hostname/ip-address) are allowed to either register, access or cancel which 'Registered Server Programs' (based on their program alias (also known as 'TP name')). Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. Despite this, system interfaces are often left out when securing IT systems. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. Part 3: secinfo ACL in detail. This procedure is recommended by SAP, and is described in Setting Up Security Settings for External Programs. With this rule applied any RFC enabled program on any of the servers covered by the keyword internal is able to register itself at the RFC Gateway independent from which user started the corresponding executable on OS level (again refer to 10KBLAZE). Benign programs to be started by the local RFC Gateway of a SAP NetWeaver AS ABAP are typically part of the SAP Kernel and located in the $(DIR_EXE) of the application server. Furthermore the means of some syntax and security checks have been changed or even fixed over time. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. P SOURCE=* DEST=*. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. If this addition is missing, any number of servers with the same ID are allowed to log on. This parameter will allow you to reproduce the RFC Gateway access and see the TP and HOST that the access is using hence create the rules in the reginfo or secinfo file; 5)The rules defined in the reginfo or secinfo file can be reviewed in colored syntactic correctness. The secinfo file has rules related to the start of programs by the local SAP instance. We can look for programs listed with Type = REGISTER_TP and field ADDR set to any IP address or hostname not belonging to any application server of the same system. You can define the file path using profile parameters gw/sec_info and gw/reg_info. In case the files are maintained, the value of this parameter is irrelevant; and with parmgw/reg_no_conn_info, all other sec-checks can be disabled =>SAP note1444282, obviously this parm default is set to 1 ( if not set in profile file ) in kernel-773, I wasted a whole day unsuccessfully trying to configure the (GW-Sec) in a new system, sorry for my bad mood. Access attempts coming from a different domain will be rejected. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. Hufig ist man verpflichtet eine Migration durchzufhren. P TP=* USER=* USER-HOST=internal HOST=internal. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. About item #1, I will forward your suggestion to Development Support. The default rule in prxyinfo ACL (as mentioned in part 4) is enabled if no custom ACL is defined. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS).Before jumping to the ACLs themselves, here are a few general tips: A general reginfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Usually, ACCESS is a list with at least all SAP servers from this SAP system. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. Only the first matching rule is used (similarly to how a network firewall behaves). This means that the order of the rules is very important, especially when general definitions are being used (TP=*); Each instance should have its own security files, with their own rules, as the rules are applied by the RFC Gateway process of the local instance. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. CANCEL is usually a list with all SAP servers from this system (or the keyword "internal"), and also the same servers as in HOSTS (as you must allow the program to de-register itself). Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use. As soon as a program has registered in the gateway, the attributes of the retrieved entry (specifically ACCESS) are passed on to the registered program. To control access from the client side too, you can define an access list for each entry. This is defined in, how many Registered Server Programs with the same name can be registered. TP is a mandatory field in the secinfo and reginfo files. Its location is defined by parameter gw/sec_info. Refer to the SAP Notes 2379350 and2575406 for the details. Part 2: reginfo ACL in detail You can define the file path using profile parameters gw/sec_infoand gw/reg_info. On SAP NetWeaver AS ABAP registering Registered Server Programs byremote servers may be used to integrate 3rd party technologies. For a RFC Gateway of AS Java or a stand-alone RFC Gateway this can be determined with the command-line tool gwmon by running the command gwmon nr= pf= then going to the menu by typing m and displaying the client table by typing 3. If the TP name itself contains spaces, you have to use commas instead. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. Please make sure you have read part 1 4 of this series. SMGW-->Goto -->External Functions --> External Security --> Maintenance of ACL files --> pop-up is shown as below: "Gateway content and file content for reginfo do not match starting with index <xx>" (xx is the index value shown in the . Notice that the keyword "internal" is available at a Standalone RFC Gateway (like the RFC Gateway process that runs at an SCS or ASCS instance) only after a certain SAP kernel version. Thank you! To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Es gibt folgende Grnde, die zum Abbruch dieses Schrittes fhren knnen: CANNOT_SKIP_ATTRIBUTE_RECORD: Die Attribute knnen in der OCS-Datei nicht gelesen werden. The RFC Gateway can be used to proxy requests to other RFC Gateways. Here, the Gateway is used for RFC/JCo connections to other systems. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. 2) It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered The Gateway uses the rules in the same order in which they are displayed in the file. Legal Disclosure | All other programs from host 10.18.210.140 are not allowed to be registered. If no cancel list is specified, any client can cancel the program. Please pay special attention to this phase! If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. If the TP name has been specified without wild cards, you can specify the number of registrations allowed here. This allows default values to be determined for the security control files of the SAP Gateway (Reginfo; Secinfo; Proxyinfo) based on statistical data in the Gateway log. In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Part 5: Security considerations related to these ACLs. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. Hinweis: Whlen Sie ber den Button und nicht das Dropdown-Men Gewhren aus! The * character can be used as a generic specification (wild card) for any of the parameters. This publication got considerable public attention as 10KBLAZE. The secinfo file from the CI would look like the below: In case you dont want to use the keywords local and internal, youll have to manually specify the hostnames. Additional ACLs are discussed at this WIKI page. Program hugo is allowed to be started on every local host and by every user. The RFC destination would look like: The secinfo files from the application instances are not relevant. Please note: SNC User ACL is not a feature of the RFC Gateway itself. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). Thus, part of your reginfo might not be active.The gateway is logging an error while performing name resolution.The operating system / DNS took 5 seconds to reply - 5006ms per the error message you posted; and the response was "host unknown".If the "HOST" argument on the reginfo rule from line 9 has only one host, then the whole rule is ignored as the Gateway could not determine the IP address of the server.Kind regards. The subsequent blogs of will describe each individually. The order of the remaining entries is of no importance. You have already reloaded the reginfo file. Based on the original Gateway log files in the system, default values can be determined and generated for the ACL files directly after the evaluation of the data found. The Gateway is a central communication component of an SAP system. secinfo und reginfo Generator anfordern Mglichkeit 1: Restriktives Vorgehen Fr den Fall des restriktiven . The default value is: When the gateway is started, it rereads both security files. You dont need to define a deny all rule at the end, as this is already implicit (if there is no matching Permit rule, and the RFC Gateway already checked all the rules, the result will be Deny except when the Simulation Mode is active, see below). For example: you have changed to the rule related to the SLD_UC program, allowing a new server to communicate with it (you added the new server to the ACCESS option). That part is talking about securing the connection to the Message Server, which will prevent tampering with they keyword "internal", which can be used on the RFC Gateway security ACL files. In these cases the program alias is generated with a random string. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. Access to this ports is typically restricted on network level. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). A Stand-alone Gateway could utilise this keyword only after it was attached to the Message Server of AS ABAP and the profile parameter gw/activate_keyword_internal was set. Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Here are some examples: At the application server #1, with hostname appsrv1: At the application server #2, with hostname appsrv2: The SAP KBA2145145has a video illustrating how the secinfo rules work. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. Please note: SNC System ACL is not a feature of the RFC Gateway itself. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. The first letter of the rule can begin with either P (permit) or D (deny). Most common use-case is the SAP-to-SAP communication, in other words communication via RFC connections between SAP NetWeaver AS systems, but also communication from RFC clients using the SAP Java Connector (JCo) or the SAP .NET Connector (NCo) to SAP NetWeaver systems. The other parts are not finished, yet. The prxyinfo file is holding rules controlling which source systems (based on their hostname/ip-address) are allowed to talk to which destination systems (based on their hostname/ip-address) over the current RFC Gateway. Its location is defined by parameter gw/reg_info. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. Part 6: RFC Gateway Logging. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. Ergebnis Sie haben eine Queue definiert. The secinfo security file is used to prevent unauthorized launching of external programs. 1408081 - Basic settings for reg_info and sec_info 1702229 - Precalculation: Specify Program ID in sec_info and reg_info. RFC had issue in getting registered on DI. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. There are two different syntax versions that you can use (not together). If you have a program registered twice, and you restart only one of the registrations, one of the registrations will continue to run with the old rule (the one that was not restarted after the changes), and another will be running with the current rule (the recently restarted registration). All other programs starting with cpict4 are allowed to be started (on every host and by every user). Save ACL files and restart the system to activate the parameters. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. Hello Venkateshwar, thank you for your comment.
