You are probably missing a route here.

Get us netstat -rn fropm both win2K and HPUX

You can also try to use traceroute to your PC from your Unix system. This will hopefully pinpoint as to what 'route' is needed.

$ traceroute xx.xx.xx.xx

Dear Michael:
From hpux to remote 172.16.1.13

In both the Win2k and HPUX your default gateway seems to be ok...
i.e. 172.16.1.254

check in /var/adm/inetd.sec of the remote server (172.16.1.13) whether there is any entry for the telnet from (172.20.1.21) to be blocked.

with best wishes

To add up,

Please check up the subnet masks in all the servers (both HP boxes)
This could also create trouble

If your router does not respond to ping, you need to disable a feature in hp-ux called "dead gateway detection".

to do so, run "ndd -set /dev/ip ip_ire_gw_probe 0".

You have to remove and add back the route to wake it up again.

route delete default 172.20.1.254
route add default 172.20.1.254 1

Hi,

I think your ping function is not disabled but you kan not use it as ordinay user,
You have to logon as root

sucess
