httptunnel info

[Jeremy Sheldon]

I’m not sure if this is the right place to ask questions or not, but I’m 
having trouble finding answers.  So, if there’s a more appropriate place for 
questions please let me know.

Here we go.  I’m attempting to use HTTPTunnel from inside a firewall with an 
ISA server.

I ran:  hts –F localhost:22 8888

I then forwarded port 8888 from my ghetto router to the machine running hts.

Then:  htc -D 4 -F 2222 -P CASSISA:8080 -A 
"sheldon_j@domain.more.long.com:XXXXXXXX" fatsheldon.machine.home.here:8888

Then I get the following error:
20040115 151946             http_parse_response: major version = 1
20040115 151946             http_parse_response: minor version = 1
20040115 151946             http_parse_response: status code = 502
20040115 151946             http_parse_response: status message = "Proxy

20040115 151946     couldn't open tunnel: I/O error
20040115 151946 exit with status = 1

Ok…  How do I determine what is causing this?  I can FTP to the same machine 
through the proxy server so why is the URL getting denied?  Anyway, I’d like 
to know what the problem is.  Any hints would be appreciated.

Thanks
