it's a new host on an existing subnet. i can ssh into the new host from other hosts on the same subnet.<br><br>route's not a problem. i can even ping that host from my workstation. the host sees connection attempts from my workstation - it just ignores them. but it answers ssh just fine from its own subnet.<br>

I'm 0 for 10 on my network troubleshooting this week, but here goes:<br>
<br>
Depending on how you set your network up, you may have an incorrect<br>
route between the two machines.<br>
<br>
A bit more background may help resolve the problem. Is this a<br>
completely new subnet, or is it just a new host on an established subnet<br>
in your network?<br>
<br>
This is what happened to me earlier this week on a virtual machine<br>
behind a virtual router connected to my main network. Basically, I had<br>
setup the incorrect gateway on the virtual router, so that My actual<br>
router was sending the packets (good enough for ping) but the virtual<br>
router was basically black-holing the packets from the remote machine.<br>
<br>
I wish I knew more about open-ssh to answer your second question. I<br>
would think that you would at least get a connection refused if it is<br>
configured to allow local subnet, but I simply don't know for sure.<br>
