Testing Firewall Connectivity on a UNIX Client

On a remote UNIX client, you can use the cvfwc_ping command to determine whether the CommServe computer can communicate with the client through the client's firewall.

cvfwc_ping attempts to establish a connection to a remote client computer through the client's firewall.

Change to the base installation directory:
```
 
cd software_installation_path/Base
```

Run the cvfwc_ping command:

 
cvfwc_ping [-inst instance_name] [-cn client_name] [-timeout  secs] remote_cnameremote_host [remote_port]

Where:

(Optional) -inst, together with -cn, specifies the local context (the instance name) of the CommCell program to run. If omitted, the first available instance in the registry, or the content of the GALAXY_INST variable (if set), is used.
(Optional) -cn, together with -inst, specifies the local context (the client name) of the CommCell program to run. If omitted, the first available virtual client in the registry, or the content of the GALAXY_CNAME variable (if set), is used.
(Optional) -timeout is the number of seconds after which the command stops trying to establish a connection with the remote computer.
remote_cname is the remote computer's client name.
remote_host is the remote computer's hostname.
(Optional) remote_port gives the port to send the request to. If not specified, the request is sent to port 8400.

Example:

cvfwc_ping -inst Instance001 -cn qm10v-ora1 qm10v-cs qm10v-cs.qm.lab 8402

Command return:

If a connection to the remote host is successful, the command returns "Successfully connected", and a return code of 0.
If the connection fails, the command returns an error message, and a return code of 1.
