Could not connect to perforce. error 'It is possible that someone is intercepting your connection to the Perforce P4PORT '10.31.64.101:1888''

Error Message:

[mohan@spl ~]$ p4 info
******* WARNING P4PORT IDENTIFICATION HAS CHANGED! *******
It is possible that someone is intercepting your connection
to the Perforce P4PORT '10.11.64.101:1888'
If this is not a scheduled key change, then you should contact
your Perforce administrator.
The fingerprint for the mismatched key sent to your client is8A:BE:F1:B9:DC:E3:50:D1:16:D6:6D:66:BB:AE:0B:26:86:C0:60:DC
To allow connection use the 'p4 trust' command.

Reason:
This happens due to environmental changes like change of ip or mac address etc. It makes the established and stored fingerprint to mismatch. So you have to reestablish the 'trust' with the server again. so we will not be able to run any command.

You have to do this by issuing 'p4 trust -f'

[build@splash ~]$ p4 trust -f
******* WARNING P4PORT IDENTIFICATION HAS CHANGED! *******
It is possible that someone is intercepting your connection

Are you sure you want to establish trust (yes/no)? yes
Added trust for P4PORT 'ssl:p4pserver.cmp.com:1888' (10.11.64.101:1888)

Now you can try some p4 commands to verify.
