Remote Monitoring

Hi,

There are Windows applications that open sockets (HTTP/HTTPS) to a
server to pass current parameter data out. But, the key is the socket
was opened behind the firewall and out to the server. Over that same
open socket the server can gain access for telnet/ssh, etc. back in.

For a Linux application, I do not want any open ports and it'll have
to traverse a firewall. SSH would be a candidate, but the firewall
prevents entry. Is there some software that will open a socket out
from a Linux box through a firewall to my server where I can gain
telnet/ssh access back in through the firewall?

Thanks in advance,
Kelli

check out setting up a vpn either w/ ppp via ssh or secure tunnel. have
your linux box initiate the vpn connection.

Maybe netcat can help you, or maybe you need an application
proxy.
