routing issue

[Michael Murphy_2]

I am having problems with connecting across unix machines on a lan/wan from one HP-ux machine. If I use telnet/ftp to try to connect - the first attempt always seems to hang. I break out and try again and it always works. Seems like a routing issue, but I don't have a lot of experience with network troubleshooting - any suggestions on where to look first?

ping "ip_Address_you_ping/telnet"

Run it for a while. Does it give timeouts in between?? -- If yes, could be a network issue.

ndd -get /dev/ip ip_ire_gw_probe
Get help on this parameter--
ndd -h ip_ire_gw_probe. If it has been set to 1, set it to 0.

ndd -set /dev/ip ip_ire_gw_probe 0
for permanent changes, put it in /etc/rc.config.d/nddconf file.

if its an hp machine you are trying to connect to:

inetd -l

enhanced logging

tail -f /var/adm/syslog/syslog.log

Try the connect, see if anything happens.

It may be possible a firewall is intervening and simply running slow. I've seen that with improperly configured Linux firewalls.

to check routes

netstat -rn
