I'm trying to reach my ssh server (i'm behind a corporate proxy) so I tried to use Corkscrew.
My ssh server is listening on port 443, I put
sshd: ALL in my /etc/hosts.allow and there's nothing into my /etc/hosts.deny.
I'm using the following command to launch a ssh session over Corkscrew :
ssh -D991 -p443 user@ssh_server_ip -o"ProxyCommand corkscrew proxy_ip proxy_port %h %p proxy_username proxy_password"
But I get the following error :
ssh_exchange_identification: Connection closed by remote host
I had the same issue when I was trying to use httptunnel (hts) and I wasn't behind a proxy (it was at home for tests).
How can I fix that?
