[PLUG] request for help in testing something...

[Kyle Burton <mortis@voicenet.com>]

First, I've heard that the 2.2 series of kernels breaks the methodology
used to create VPNs based on the VPN mini howto.  The reason that 2.2
breaks the methodology, afaik, is that it breaks the pty-redir utility.
The reason this happens, afaik, is because pty-redir looks for the 
controlling pty by stepping through all of the ptys in the /dev directory
looking for the first one that it finds that is both readable and writable 
by the uid of the process running pty-redir.  Again, afaik, this breaks on
2.2 because of the unix98 ptys -- they're in /dev/pts, and named differently
(eg: /dev/pts/1) instead of /dev/pty??.  So, I looked at the sources for 
pty-redir and tried to get it to work for the 2.2 kernel.

One major change I made was to use ttyname(3) instead of trying to find
the name by searching the file system -- so this should deterministicly
get the pty name -- and, in theory, it should work for 2.2 and 2.0 series
kernels, as we're not searching for the file name, we're asking for the 
name.

Anyway, my problem is I can't really test the rest of the equasion -- I
don't have 2 boxes where I can try setting up a VPN between.

My question to those of you on the list is:  would anyone on the list be
will be willing to help me test this version of pty-redir2 to see if it
can be used under either kernel version to create a VPN based on the 
instructions in the VPN howto.  The 'new' version can be obtained from:

http://www.bgw.org/projects/pty-redir2/

If you do wish to try it, please download the pty-redir2-20000128.tar.gz,
the pty-redir2.tar.gz was the first version and tried to follow the original
pty-redir's methodology for finding the controlling pty, which could have
lead to problems (I think), so it's probably best not to use it.

Thanks for your time,
Kyle
