But, where do I do port mapping? I tried putting it in the ssh-config file, (/usr/bin/ssh-config)as below: proxy.domain.com:1800 -> proxy1:22 I run SSH as: ssh -i ssh-server/identity -p 2022 -o "HostkeyAlias=proxy1" -o "CheckHostIP=no" user AT proxy DOT domain DOT com I get the following error: command-line: line 0: bad configuration option: HostKeyAlias ??!!?? Regards, Shuba -----Original Message----- From: Michael Erdely [mailto:cygwin AT cygwin DOT com] Sent: Wednesday, July 11, 2001 3:04 PM To: cygwin AT cygwin DOT com Subject: RE: SSH on multiple ports Shuba, I'm not running OpenSSH_2.3.0p1, I'm running OpenSSH_2.9p1. I'm not sure if it's different. But I have the same problem: My ssh hosts are behind a firewall. I do port mapping like this: firewall.ip.address:8022 -> host1.internal.address:22 firewall.ip.address:8122 -> host2.internal.address:22 >From "man ssh", I found the HostKeyAlias and CheckHostIP options. When I want to connect to host 1, I use: ssh -p 8022 -o "HostKeyAlias=host1" -o "CheckHostIP=no" user AT firewall DOT ip DOT address When I want to connect to host 2, I use: ssh -p 8122 -o "HostKeyAlias=host2" -o "CheckHostIP=no" user AT firewall DOT ip DOT address I do not get prompted for the key change problem. I hope this helps you. -ME > -----Original Message----- > From: cygwin-owner AT sources DOT redhat DOT com > [mailto:cygwin-owner AT sources DOT redhat DOT com] On Behalf Of Simha, Shuba > Sent: Wednesday, July 11, 2001 1:38 PM > To: Cygwin (E-mail) > Subject: SSH on multiple ports > > > I have Cygwin-1.1.5 with OpenSSH_2.3.0p1. > > I am using Expect to connect to a proxy through SSH.
