Operating Systems AIX Telnet or rsh takes too much time Post 302768443 by hicksd8 on Friday 8th of February 2013 02:34:56 PM

As Zaxxon says, the first thing to check is the DNS service. The delay could be all caused by a very slow resolution process.

What happens if instead of

Code:
telnet <nodename>

you enter

Code:
 
telnet <ip address>

Do you still see the delay?

Otherwise, can you introduce a third system into this and see if you can tell which node is causing the problem?

Also, just noticed you are using 10.1.1.* ip addresses. Are you sure that your network knows that these ip's are local and not out in the big wide world?

RSH(1C) 																   RSH(1C)

NAME
rsh - remote shell SYNOPSIS
rsh host [ -l username ] [ -n ] command host [ -l username ] [ -n ] command DESCRIPTION
Rsh connects to the specified host, and executes the specified command. Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally terminates when the remote command does. The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote name must be equivalent (in the sense of rlogin(1C)) to the originating account; no provision is made for specifying a password with a com- mand. If you omit command, then instead of executing a single command, you will be logged in on the remote host using rlogin(1C). Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote machine. Thus the command rsh otherhost cat remotefile >> localfile appends the remote file remotefile to the localfile localfile, while rsh otherhost cat remotefile ">>" otherremotefile appends remotefile to otherremotefile. Host names are given in the file /etc/hosts. Each host has one standard name (the first name given in the file), which is rather long and unambiguous, and optionally one or more nicknames. The host names for local machines are also commands in the directory /usr/hosts; if you put this directory in your search path then the rsh can be omitted. FILES
/etc/hosts /usr/hosts/* SEE ALSO
rlogin(1C) BUGS
If you are using csh(1) and put a rsh(1C) in the background without redirecting its input away from the terminal, it will block even if no reads are posted by the remote command. If no input is desired you should redirect the input of rsh to /dev/null using the -n option. You cannot run an interactive command (like rogue(6) or vi(1)); use rlogin(1C). Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here. 4.2 Berkeley Distribution April 29, 1985 RSH(1C)
