Check for DNS resolving issues and check if there is a performance problem on the box you come from or where you go as destination. Maybe also check if there is a network problem with something like
traceroute .

traceroute Code:
C:\>tracert 10.1.1.100 Tracing route to 10.1.1.100 over a maximum of 30 hops 1 13 ms <1 ms <1 ms 10.1.1.101 Trace complete. how can I check for network problem or performance issue on the box where i want to telnet to ? thanks Last edited by filosophizer; 02-08-2013 at 02:00 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? |

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. |
