[Sheflug] pts/x (fwd)

[Guennadi Liakhovetski <nospam [at] ragingbull.com>]

Hi, I started this thread on comp.os.linux.misc, because wasn't sure where
it should go (and I still am not). But maybe somebody here knows an
answer or at least where to look for one...

Yep, I also thought so, but... it looks like there appear holes in the
sequence (with time): on one of these 2 machines there is a hole at pts/2,
if, say, you have pts/1 and pts/3, then you close pts/1 and start opening
new ones, they appear in the following order: 1,4,5,6,... - 2 never gets
filled... On the other machine I currently have holes at
pts/1,3,4,6... One machine is SuSE6.4 + 2.4.2 kernel, another one is
SuSE7.0 + 2.2.18... What's interesting, when I had that problem with 2
extra lines in `who`, they were pts/2 and pts/4. At one stage I even had 2
lines with pts/4... Then pts/4 somehow miraculously disappeared... to remove
pts/2 I had to re-create /var/run/utmp... Now there's no more extra lines
in who - they are quite consistent, but pts/2 is still blocked... Don't
know though how those holes appeared on the other machine...

Thanks
