Verify the connection to the server

To verify a connection, run the p4 info command.

p4 info

If P4PORT is set correctly, information like the following is displayed:

User name: bruno
Client name: dhcp-133-n101
Client host: dhcp-133-n101.dhcp.perforce.com
Client unknown.
Current directory: /Users/bruno/tutorial
Peer address: 127.0.0.1:49917
Client address: 127.0.0.1
Server address: localhost:1666
Server root: /Users/bruno/server
Server date: 2016/03/01 16:15:38 -0800 PST
Server uptime: 00:03:26
Server version: P4D/DARWIN90X86_64/2015.2/1340214 (2016/02/03)
Server license: none
Case Handling: insensitive

The Server address field shows the host to which p4 connected and also displays the host and port number on which the Helix Core Server is listening. If P4PORT is set incorrectly, you receive a message like the following:

Perforce client error:
   Connect to server failed; check $P4PORT.
   TCP connect to perforce:1666 failed.
   perforce: host unknown.

If you get the "host unknown" error, speak to your administrator.
