Hi, I would like to scale PPTPD to 2048 maximum simultaneous
clients by re-compiling the kernel (2.6.18) as is referred to in Jeff Blaize’s
How-to (see below for exerpt). I am having trouble determining exactly which
parameters need changing in the kernel source. Would someone please be able to
provide me more specifics on what needs changing to increase per-process file
descriptors, ttys and max processes etc as indicated below. Also he refers to
code changes that need to be made in libc/kernel, any info on this would be
appreciated if that is still necessary. thanks! Steve See Jeff Blaize’s How-to Below The limits under
Linux are:
So
it seems that 2048 will be the limit, if you fix a few things and with a minor
kernel mod (I could do all of these pretty easily and send you a trivial kernel
patch). To go above 2048 the easiest approach would be to combine pptpctrl and
pppd in one process, which would get you to 4096. Beyond there, you need to go
for a select() based model, which would be significant coding effort and
require large fd-set sizes and so on. So 4096 is the practical limit, and 2048
the easy limit. Steve Pearson Network
