Pre-Installation

B.2 Pre-Installation

In seas_forwarder.cfg file, the format of IP and port mapping (ipMap parameter) should be maintained in json. The new IP and port number added should be comma separated. Refer toSample seas_forwarder.cfg file for example.
In seas_forwarder.cfg file, STP IP address and port number should be correct i.e.; it should be the one on which CCSMR is listening or the connection will not be successful.
The user who is receiving subsystem request should have all the permissions (read, write and execute) for the seas_forwarder.py file subdirectory. User can use chmod command to grant permission to the user.

To identify which user will receive the subsystem request, check rtrv-seas-config command on STP. Login will show the user name. In the example below, we can see that login name is tklcuser, so tklcuser will receive the subsystem request on the Linux machine.

rtrv-seas-config
    Command entered at terminal #3.

    IPMR2    ----- -----             -----  -----           -----

Alternatively, you can verify the above point from Linux machine as well. The command tail –f /var/log/secure will show the user who will receive request.
```
Feb 18 04:24:43 iptool11804 sshd[19010]: Accepted password for tklcuser from 10.75.136.166 port 64127 ssh2
```
The user who will receive subsystem request should have read access to file /var/log/secure. If not, then grant the permission to this user. Refer to Grant Permission which explains the steps to grant the permission to a particular user.
If STP seas terminal is allowed but STP is not connected to CCS-MR then check whether “seas” subsystem request is received on Linux machine using command mentioned in step 4. User also needs to recheck the IP address and password on the STP side. If no request is received, follow step a and if still request is not received then follow step b.
1. On STP side, inhibit and allow the seas terminal.
2. After executing 'step a’ on STP side, if seas subsystem request is still not seen on the Linux machine, then initialize the IPSM card.
