Ethernet Ports Used for ACSLS Communication

The following ports are used on the ACSLS server. Ensure that any firewalls are configured to allow traffic to these ports. This included firewalls implemented by ipfilter on Solaris or iptables on Linux.

22 both directions – used for ssh access.
111 portmapper, unless portmapper has been disabled.
115 used for SFTP (Secure File Transfer Protocol).
5432 default port for internal communication from ACSLS to the PostgreSQL database (the PGPORT environment variable for the acsss user ID).
If port 5432 is taken, the next available higher port number is used.

Note:
Port 5432 only needs to be accessible from localhost (127.0.0.1).
7001 and 7002 - used by WebLogic and the ACSLS GUI.
30031 or the ACSLS CSI’s listening port, set by CSI_INET_PORT.
50003 port used for internal communication from the ACSLS GUI and Java components to legacy ACSLS processing. This is not configurable.

For client applications to communicate with ACSLS through the ACSAPI, the following ports must be open:

The client application must be able to communicate with the ACSLS CSI’s listening port. This defaults to 30031, and is set by the CSI_INET_PORT static variable.
You can discover which ports are in use by ACSLS to listen for requests from ACSAPI clients with the following command from your Unix shell:
```
rpcinfo -p | egrep "300031 | 536871166"
```
The port IDs will be listed in the last field of the display.
The ACSAPI client (for example, a NetBackup or SAM-QFS server) sets its fixed incoming port using the SSI_INET_PORT environmental variable. Specify a port in the range of 1024-65535, excluding ports 50001 and 50004. The ACSLS server must be able to communicate with this port.

Note:
On an ACSAPI client server, ports 50001 and 50004 are used for AF_INET domain IPC communication to the mini-Event Logger and from client applications to the SSI.

See the "Firewall Secure Option" appendix in the ACSLS Administrator’s Guide for more details about communication between client applications and ACSLS.

If the XAPI component is installed, the XAPI server uses a fixed listening port to receive incoming TCP requests from ELS clients. The XAPI listening port is defined by the XAPI_PORT static variable. XAPI_PORT defaults to 50020. It must be between 1024 and 65535, and cannot conflict with any other port used by ACSLS or other applications.

Refer to the XAPI Client Interface appendix in the ACSLS Adiminstrator’s Guide for more details about the XAPI_PORT. This appendix also provides details about how to display and set the XAPI_PORT static variable.

Ports that must be open on an SL8500 or SL3000 library:

50001 – Used for all normal communication between ACSLS and the library.

ACSLS communicates with these ports on an SL8500 or SL3000 library’s 2A and 2B Ethernet connections. If communication from ACSLS to these ports is blocked, ACSLS cannot manage the library.
