Hi,

I referred to KERNEL 2.4.14 with patch-2.4.15pre3

I did recompile vtund AFTER my new kernel installment and startup and it
didn't help.
I traced vtund and it opens /dev/net/tun
the ioctl call after it returns the error

----------------------------------------- from the trace

writev(2, [{"vtund[27645]: Session demo_s[127"..., 51}, {"\n", 1}], 2) = 52
rt_sigaction(SIGPIPE, {0x40137270, [], 0x4000000}, {SIG_IGN}, 8) = 0
send(4, "<30>Nov 13 19:37:48 vtund[27645]"..., 71, 0) = 71
rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0
open("/dev/net/tun", O_RDWR) = 7
ioctl(7, 0x54ca, 0xbffff18c) = -1 EBADFD (File descriptor in
bad statclose(7) = 0
time([1005676668]) = 1005676668
getpid() = 27645
writev(2, [{"vtund[27645]: Can\'t allocate tun"..., 73}, {"\n", 1}], 2) = 74
rt_sigaction(SIGPIPE, {0x40137270, [], 0x4000000}, {SIG_IGN}, 8) = 0

----------------------------------------

I'm willing and able to do more tests

regards
Kees
