Mark,
Your web page has on it what can be an extremely harmful shell script:
#!/bin/sh
# file: /usr/local/bin/vat
# simple script to remove the RTP (-r) option for vat 3.4
# I also had problems with the conference name not being quoted,
# so as a quick-fix I removed that also
ARG=`echo $@ | sed "s/-C .* 2/2/" | sed 's/-r//'`
exec /usr/local/bin/vat3.4 -U /tmp/vatsock ${ARG}
If you want to have an old vat session, you should tell sdr that when creating
the session and it will launch vat properly. If you just remove the "-r",
then some people (the people with this script) will be using the vat protocol,
and some people (the people with vat 4.0) will be using RTP. These two groups
of people will not be able to talk to each other, even though they are using
the same IP address and the same port, because they will be speaking different
protocols.
If vat 4.0 is not usable for some reason, then you should change the
SDR announcement to use the vat protocol, you shouldn't just run the old
vat. That's similar to people advertising that they're transmitting in
nv format but then using vic and h.261 -- some people just aren't going
to get it. Fragmenting the user community is just going to make people
say that the MBONE doesn't work, and there are already plenty of real
problems with the MBONE; let's not make more.
Thanks,
Bill
