Remote Login Problem After Hostname and IP Addr Change

[Frank Sam]

We’re TRYING to put an HP9000 rp5470 behind the organization's network firewall; we're running on HP-UX 11i v2.3. To do so, we had to change the hostname (FQDN) and IP address. We made the changes and are now running into a problem remotely logging in.

While port 22 is, by default, open on the network firewall, the only time we are able to log in remotely via ssh is when the rp5470 is rebooted; that initial login times out after a minute or two. Any further remote login attempts are unable to connect and end up timing out.

Any advice? Thanks.

Hi Edqardo

It looks like DNS problem.
Did you update your DNS records with your new ip address and hostname

Hi,

i don't know it solves your problem but regenerating keys sounds good to me if it includes hostname.

Do you loose all net connectivity after that first few minutes after reboot ??

If so it is an gateway_probe problem..

Most firewalls do not respond to icmp. The default gateway config is set to disable the default route if the gateway does not respond to an icmp probe.

disable the probe using ndd -set /dev/ip ip_ire_gw_probe=0

for description
ndd -h ip_ire_gw_prob

You will need to put the disable in your /etc/rc.config.d/nddconf file in order to make permanent after reboot.
