Operating Systems AIX Telnet or rsh takes too much time Post 302768471 by filosophizer on Friday 8th of February 2013 03:40:49 PM

Code:
telnet <nodename>



 
telnet <ip address>

Both give delay of more than 3 minutes for the login , but another machine on the same network works fine IP and nodename.

How can I isolate the problem to DNS or server-performance-issue ?

DNS is windows DNS Server..



POST-SCRIPT: ISSUE SOLVED

Deleted the file /etc/resolv.conf
the file had an entry

and removed name-server and stopped nameserver from smitty tcpip

Issue resolved.

as Zaxxon said, the first issue to look for should be DNS.

RESOLV.CONF(5)							File Formats Manual						    RESOLV.CONF(5)

NAME
resolv.conf - Domain Name System resolver configuration SYNOPSIS
/etc/resolv.conf DESCRIPTION
The /etc/resolv.conf is used to configure how the host will use the Domain Name System to resolve hostnames to IP addresses. It may con- tain these two lines: nameserver IP-address domain domain-name The nameserver entry tells the IP address of the host to use for DNS queries. If it is set to 127.0.0.1 (which is the default) then the local name daemon is used that may use the /etc/hosts database to translate host names. You normally only need a nameserver entry if the name server is at the other side of a router. The default nonamed name server can't look beyond the local network. The domain entry tells the default domain to use for unqualified hostnames. This entry is usually not given in which case the domain of the local host is used. The long version of this story can be found in resolver(5). FILES
/etc/resolv.conf DNS resolver configuration file. SEE ALSO
