our VPN server is using mpd3.18 + freebsd6.1

but when i try to make 500 connections
the mpd failed to run.
i suspect it was the freebsd
that can not provide ng more than 250.
is there anything i should do ?
maybe tuning the freebsd ?
mpd3 uses about 10 file descriptors per bundle. So you should increase
file limit via sysctl.
Another problem is dependence of mpd and libradius on select() call
which will require increase of FD_SETSIZE constant in mpd/system and
rebuilding mpd and libradius.
But if you whish to reach 1-2K bundles and more, you may need mpd4.
There are lot of changes done to remove that kind of limitations in
mpd4.0b5. So if you don't use MSCHAP auth (which was broken in mpd4.0b5
and fixed later) I propose you to try mpd4. Or you can try latest CVS
version from sourceforge.net which is stable enough for now and moving
to release.
