scp: port 22: No route to host


I started a ssh connection between my computer and a server. Everything works fine. Then I tried the comman scp to copy a file from the server to my computer, and got the following message:
OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to [] port 22.
debug1: connect to address port 22: No route to host
ssh: connect to host port 22: No route to host

Any suggestion? Thanks a lot.

Hi there,
There are some options :
1) check out if there ia firewall in between. also first ping your own machine, your gateway, a machine outside your network and then a remote server. you can understand where the problem lies by this. perhaps a configuration in between is preventing your connection.
2) also please check your "/etc/ssh/ssh_config" file which is the client's file for ssh configuration. I think the problem is the configuration in "/etc/ssh/ssh_config". here just comment any lines with just the " Host " line. this should make it work most probably. if problems persists please post the errors again....

the thing is that ssh works. I can connect to the server without any problem. I get problem as soon as I use scp although it uses port 22 too.

check your resolv.conf people!

I've had he same issue trying to scp files and folders from one linux machine over to another one on the same network.
Machine A had an externally accessible IP and machine B had a local network IP. so Machine A couldn't find the route to host B because it went searcing through my external gateway while machine A was using the internal gateway.

so, i gave machine A a fixed external IP as well and added my external gateway to the /etc/Resolv.conf. done! i can now scp/ssh with no problem.

Good luck everyone!

I was stuck on this also. If in a non prod / lab environment, you can try the command "service iptables stop" and then try again. If scp or ssh works, the issue would seem to be in the iptables.
