Please help icmp destination unknown port unknown

I think the 'nc' command you executed was wrong. You have to listen on UDP port 5060.

Quote:

udp 0 0 127.0.0.1:32789 127.0.0.1:5060 ESTABLISHED 11043/nc

Use

Quote:

nc -u -l -p 5060

to listen on UDP port 5060

You are yet to stop the SIP server.

Quote:

udp 0 0 127.0.0.1:5060 0.0.0.0:* 11008/ser

is this ok

hi2arun · 09-02-2011, 08:26 AM

iptables stop is fine.

But did you take care of 'nc' and 'SIP server' as discussed?

maybe I could use ssh to redirect to eth0

hi2arun · 09-02-2011, 08:29 AM

Cool. After you got the some message on 'nc' terminal, type something back on 'nc' terminal.

Can you attach packet capture output for this?

thanks a million

Here you can see the message that you typed... so this reached the SIP client.

This means, if you run the SIP server listening on eth0 interface of the Linux instance, things will be fine.

HTH!
