Mailing List Archive: Timeouts after upgrading to V8

Hi folks,
We have been using V7 (and its updates) of conserver for over a year.
While trying to get V8 working I
have run into a problem that I am having trouble resolving. When the
conserver first starts up and connects to all of consoles (all consoles
are through terminal servers) the connection is made and promptly 10
seconds later the select times out and the consoles are dropped. I have
watched the connection from the
terminal server side and the connection is actually made to the
terminal server.

The configuration of the system is this:
FreeBSD V4.3 & 4.7.
conserver V8.0.8
Terminal servers are all either DECserver 700s or Lantronix
There are no special options set via configure on building conserver.

So... What am I missing here? Everything works fine with V7.2.7 but the
consoles timeout w/V8.0.8.

Thanks in advance for any help...

ugh...at first i thought it might be a freebsd compatibility issue. i
ran tests connecting to my web server, ssh port, etc. all worked fine.
then i actually tried to connect to an external machine (google web
server). it failed in the same way you are seeing...it connects, but
then times out.

i'm at a loss. obviously i've done something different in 8.0.8 vs.
7.2.7, but i haven't figured out what, yet (aside from major changes to
all the logic). it looks like this is a problem with solaris and linux,
as those are the two systems i can test on.

what i don't understand is why socket connections to the local machine
work. in some cases the initial connect() returns a success, so all is
well (fast enough even though it's non-blocking). but, i also get an
EINPROGRESS on local connections and then the select() shows the file
descriptor ready for a reading, and it disables the timeout for that
console - but the other non-local-machine consoles still time out and
select() never shows them as ready.

so, it's bizarre, but i'll be looking into it. if anyone has ideas, i'd
love to hear them.

more as i come across things...boy, this is bad.
