[jadmin] Re: s2s connection problem

[Norman Rasmussen]

I've been trying

socat -d -d - tcp:server.address:5269

and get this:

2007/07/13 11:17:28 socat[2772] N reading from and writing to stdio
2007/07/13 11:17:28 socat[2772] N opening connection to AF=2
ip.ad.dr.es:5269
2007/07/13 11:17:32 socat[2772] N successfully connected from local address
AF=2 my.ip.ad.dr:4486
2007/07/13 11:17:32 socat[2772] N starting data transfer loop with FDs [0,1]
and [3,3]

and if I type anything and hit enter it ignores me.  (compared to any other
server, which disconnects with a stream-error)

It's probably one of the following:

1) you've got some weird firewall blocking returning data:

At a tcp level the data being sent to the server is being ACK'ed. (seen via
tcpdump), so it's not like traffic is being 100% blocked after the
connection is being made.  Perhaps too much is being blocked though :-(

2) the s2s component isn't receiving the data correctly:

It would seem that your test from dip.t-dialin.net confirms that this is not
the case.  It is possible that perhaps the connections are being redirected
at another firewall somewhere? or that your dial in IP got special
treatment?

What else is running on these servers, do they have any vpn software?
