Sign on your your RS6000. Use the command
"nslookup 111.222.333.444"
but using the ip address of your pc. This will try to find the hostname of your pc. When you login, the system does this. It has your IP address and it wants your hostname for logging purposes. Ditto for ftp, but some ftp servers reject a connect if they fail.

Use our search function. Look up "reverse dns ftp". This is a somewhat frequently asked question.

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME
tcp-env - set up TCP-related environment variables SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ] DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several environment variables as described in tcp-environ(5), and runs program with the given arguments. Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check whether the input is a TCP connection. OPTIONS
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host. -R Do not attempt to obtain TCPREMOTEINFO from the remote host. -ttimeout Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30. SEE ALSO
tcp-environ(5), inetd(8) tcp-env(1)
