tcp-connect error

["John R. Hall" <overcode@lokigames.com>]

I developed some nifty networking code on a Windows box with MzScheme.
It puts a nice OO wrapper around Internet connections established with
tcp-connect. Unfortunately, the same code does not work on my Linux box
(SuSE 6.3, kernel 2.4.0test6). It seems that tcp-connect is encountering
problems.

[overcode@linux] overcode$ mzscheme

> (tcp-connect "localhost" 23)
#<tcp-input-port>
#<tcp-output-port>

Ok, it worked once.

> (tcp-connect "127.0.0.1" 23)
tcp-connect: connection to 127.0.0.1, port 23 failed (at step 4:
Resource temporarily unavailable; errno=11)
> (tcp-connect "localhost" 23)
tcp-connect: connection to localhost, port 23 failed (at step 4:
Resource temporarily unavailable; errno=11)

Then it fails.

> (tcp-connect "www.google.com" 80)
tcp-connect: connection to www.google.com, port 80 failed (at step 4:
Resource temporarily unavailable; errno=11)

Unless California just got nuked, Google should be there :)

Here's some general machine info:

Any suggestions appreciated. I ran these tests immediately after a
reboot, and I know my network connection is working.

Thanks!
