Cisco ASA 5505 connection issues #6

Open lucasalvarez opened 9 years ago

Hi, trying to connect to a Cisco ASA 5505, I found that the option subcommands SB and SE were not being catched, so I have added this codes cmdSB and cmdSE to line 111 of conn.go. That allowed me to connect and to send commands succesfully.

Regards,

Lucas

It seems that ASA 5505 uses subnegotiation commands without negotiate with client to allow it. I added code that skips all subnegotiation bytes. But I can't reproduce your issue so please try last commit and report does it fixes it.

I played with my Cisco router and I can successfully obtain output of sh ver command (see chnged example). To prevent IOS to page command outputs I added partial support for NAWS command that sets client window to 65535 x 65535.
