Here's an interesting problem that's stopping root from using the
wonderfully useful program "screen"
Nobody can read/write to /dev/ttyp4, ttyp3/5 are fine, but 4 doesn't
work:-
crw--w---- 2 jjn terminal 6, 3 Mar 17 09:01 ttyp3
crw-rw-rw- 2 root system 6, 4 Mar 17 10:08 ttyp4
crw--w---- 2 root terminal 6, 5 Mar 16 16:34 ttyp5
byron[root]30: echo hello >/dev/ttyp3
byron[root]31: echo hello > /dev/ttyp4
/dev/ttyp4: No such device or address.
byron[root]32: echo hello > /dev/ttyp5
It looks to me that something has grabbed the underlying device and won't
let go...
Any ideas?
OS is v5.1 PK2 [single node, not clustered]
Regards,
Jonathan
