Since you have no network connectivity from a certain
location, I'd suspect routing or access list issues.
There are some tests you can try from both locations:
telnet oldserver 22
telnet newserver 22
You should see something like:
Trying aaa.bbb.ccc.ddd...
Connected to aaa.bbb.ccc.ddd.
Escape character is '^]'.
SSH-1.99-OpenSSH_3.9p1
Protocol mismatch.
Connection closed by foreign host.
Even if you have tcpwrappers, you'll still get:
Trying aaa.bbb.ccc.ddd...
Connected to aaa.bbb.ccc.ddd.
Escape character is '^]'.
Connection closed by foreign host.
Verify the network that both locations are on, and
compare to the routing on the new system.
It could also be an access list issue on the router.

are you forcing it to only accept connections from a

(1,2) /etc/ssh/sshd_config or do you have
TCPWrappers set?
What are the /var/log/secure or likewise files
telling you on the server
that you can not access?
just a few thoughts

Hi, I.m hoping someone can shed some light on a
confusing problem for me.
I administer 2 servers for sendmail/http/dns and
have recently just upgraded one of them (a solaris 8
sparc) to OpenSSH_4.0p1, OpenSSL 0.9.7e 25 Oct 2004
The older machine is a redhat 6.2 x86 machine
running SSH Version 2.0.13
I recently started work at a new company and i am
unable to ssh into the ssh-upgraded server remotely.
Nor will it service http requests from this
location. The older machine however works just fine
and I can ssh in no problem.
The confusing thing is that when I try to access
my machines from a friends network the upgraded
machine works fine and I can log in using ssh.
I am logging in using the latest version of putty
on the same win2k m/c in every case
Can anyone tell what is about the upgraded ssh/ssl
machine that causes it to stop responding to ssh
requests (and http requests) from one particular
location but is ok from other locations. The other
machine running the older version of ssh works fine
and I.m able connect to it fine from my new work
location,
TIA.
