Hi,
ppp in 4.x apparently does a close(2) after opening the tun device;
i4brunppp starts up with only file descriptors 0 and 1 open (to the rbch
device) -> tun gets opened as 2 -> tun gets closed -> later use results
in EBADF. A quick fix to i4brunppp.c makes the thing work (I know, this
is ugly, but I needed it up quick...):
--- i4brunppp.c-orig Wed Dec 20 00:47:32 2000
+++ i4brunppp.c Wed Dec 20 00:48:06 2000
@@ -164,6 +164,7 @@
i = getdtablesize();
for(;i >= 0; i--)
+ if (i != 2)
close(i);
/* fiddle a terminating zero after the rbch unit number */
Cheers,
- Juha
