If the server you're connecting to is an SSH1 server, you're going to have to enable SSH1 on your FC5 client. Or if you have control over the server you're connecting to, change the settings or update the SSH software to allow SSH2 connections. One thing I find helpful when I'm troubleshooting ssh is connecting with $ ssh -v some_host The "-v" is for verbose mode. You can get more information with "-vv" and even more with "-vvv". One thing you'll be able to do is to see if your connecting and getting rejected by the server (which means it's not a firewall problem) or whether you're not connecting at all (could be a firewall problem, either on your end or theirs). Indications are that it's not a firewall problem since you were able to use telnet to connect to port 22 on the remote server. === Al --- RyAnZ <nocph@xxxxxxx> wrote: > Hi, sorry my English is not that good that's why I minimize my words. > > Here are some details...
