Can anyone please advise me as to
the maximum number of SLIP or PPP
connections that the 2.0 kernel can support.

Im looking to setup a SLIP/PPP server and read 
somewhere that the max SLIP connections was 8 
sl0->sl7 but this may have been for an earlier
kernel version.

Any help would be greatly appreciated

There is no theoretical limit to the number of devices. Eventually you
will hit a practical limit of memory, table entries being overflowed, or
CPU processing limitations in that the system just can't dispatch the
processes fast enough.

There is a pseudo limit of 256 devices. That is just to ensure that the
table search routines don't run on forever.

You can change the limit when you load the module or by a define if you
build the PPP or SLIP driver into the kernel.

You must have been reading about some other operating system. The
previous limits were more likely 4 or 16 devices since the table
entries were statically allocated.

If it will help, I know of at least one ISP which is running 128
simultaneous PPP connections on one system. Jon make one of his
computers a 'super' terminal server. It is built with 4 32 port
RocketPort cards.
