Being fortunate enough to have "spare" partition on one of our disks,
I'm backing up my root partition (on a DECsystem 5500 under Ultrix 4.1)
to disk, using afio (since the Ultrix cpio is broken, but that's
another story).
My question concerns the following three items in /dev:
/root.bak/dev/snmp
/root.bak/dev/elcscntlsckt
/root.bak/dev/printer
These are all sockets, and I can't copy them using afio/cpio or tar.
That's all I know about them.
Obviously I'd like to know what's happening here. What are these
files? How are they created? Can I back them up? If not, can I
recreate them in my spare partition?
Thanks in advance,
- Steven

They are dynamically created by the programs / function that use them, so there is no need to worry about backing them up. As far as what they're for, /dev/printer is used by /etc/lpd and documented in the lpd man page. The others are for error logging and I guess SNMP network magnagment daemons. -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)

You Mention that you are backing up "/" to a spare disk with "apio" or something similar... Why don't you just use "dump" ?????? I us it to dump an entire server system by piping the output from dump to comnpress. I then tar the files together and ftp them to the IBM mainframe... but that's another story. -- Bill Bailey <dbgwab@arco.com> Voice : (214) 754-6779
