Telneting from linux to HP-UX
When I telnet from my Red Hat box to a HPUX server it does connect but only after about
15 seconds or so go by. Doing the same thing from a Windows box it connects right away!
Both are on the same subnet,gateway and so on.
What is missing if anything?

Re: Telneting from linux to HP-UX
It could be a name resolution issue. Check to see that each box can resolve the other one via nslookup, and also check the reverse lookup using the IP address.

Re: Telneting from linux to HP-UX
by any chance does this has anything to do with the reverse lookup.
the server which you connects to tries to use a reverse dns lookup and see if it can validate the ip?
try adding the hostname of the linux box to /etc/hosts file on HPUX and see if it helps.
also, can u post the relevant clippings from the syslog on HP unix.
and are you sure that there is no issue with the DNS settings on the RHL box.
some how i think that the problem is with DNS.

Re: Telneting from linux to HP-UX
Check if you made ping and other services
if this also take time.

Re: Telneting from linux to HP-UX
If you have a DNS server, preferably HP-UX or Linux, servicing the local domain, you'll get very fast connect.
I had the exact same problem in my web hosting business on the internal network. The second I had the webserver do DNS for local machines the connects were instant.

Re: Telneting from linux to HP-UX
To test if this is anything to do with hostname resolution, try to TELNET using the IP address instead of the hostname.
If it connects straight away, you can be pretty sure the problem has been identified.
