Is the machine you are using (a PC perhaps) on the same network (no routers)? Can you ping the HP-UX machine? Can the HP-UX machine telnet to another machine on the same network? Has someone recently edited the /var/adm/inetd.sec file?

Hi Jagadesh,

Check the /var/adm/inetd.sec and see if you may contact the machine from that partical machine.
Also try from the server to connect to other machines.

grtz. Mark

Hi Jagadesh

As above idea, Just check for /var/adm/inetd.sec file.
Here is copy/paste from inetd.sec file's content:

# The lines in the file contain a service name, permission field and
# the Internet addresses or names of the hosts and/or networks
# allowed to use that service in the local machine.
# The form for each entry in this file is:
#
#
#
# For example:
#
# login allow 10.3-5 192.34.56.5 ahost anetwork

You can modify the service and IP address that can connect to ther server.
For example (modify the inetd.sec from server has IP address: 10.200.125.201):

telnet allow your_ip_address

Hope this helps
Regard,
Hoang Chi Cong

I think this is a problem with stty setting? It may not be a /var/adm/inetd.sec bcas it will not allow to even to connect with machine.

I think this is a problem with stty setting? It may not be a /var/adm/inetd.sec bcas it will not allow to even to connect with machine.

Just do as,

# stty ixon

and put into the /etc/profile file.
