OpenSSH connection to www.linux.org.il from a machine with a private class B IP which is behind a firewall+proxy server?
As suggested in the past I am trying to ssh to www.linux.org.il in order to be
able to help with its content. Since I am behind a firewall+proxy server I
have to use a socks server.
[09:29:03 /tmp]$ socksify ssh -v www.linux.org.il
SSH Version OpenSSH-1.2.2, protocol version 1.5.
Compiled with SSL.
debug: Reading configuration data /etc/ssh/ssh_config
debug: Applying options for *
debug: ssh_connect: getuid 1000 geteuid 0 anon 0
debug: Connecting to www.linux.org.il [192.116.202.69] port 22.
debug: Allocated local port 643.
And nothing more. I have to ^C it.
Ira claims that
"now I see attempts from 172.17.120.5 which is ofcourse NOT a legal
address. something is wrong with your firewall config, I'm afraid."
172.17.120.5 is indeed my IP.
Before trying to talk with the sys admin I would like other members of the
list to review it. Isn't a private class B IP might be expected from a machine
behind a firewall+proxy server on a private network? What can I ask from the
net admin beside a non private IP?
I believe that it is worth mentioning that I can socksify telnet and socksify passive ftp to www.linux.org.il.
