Operating Systems SCO mirroring in lan between 2 pc Post 302175875 by jgt on Sunday 16th of March 2008 01:31:03 PM

Thanks for the PM, but it would be better if you respond in the thread so that others may also benefit.
So you have two SCO 5.0.5 machines that you want to have mirror each other.
If you are looking for a magic bullet, forget it.
SCO have solutions based on 5.0.7 and Unixware, that will provide this kind of product if you need minute by minute redundancy.
If you can live with once per hour or per day mirroring then use either NFS or FTP to copy the changed files from the primary system to the backup system.
An alternative is to add transaction logging to your application on the primary system, and have a background process on the secondary machine post those transactions to the data files on that machine.

NAME
rwho -- who is logged in on local machines SYNOPSIS
rwho [-a] DESCRIPTION
The rwho command produces output similar to who, but for all machines on the local network. If no report has been received from a machine for 11 minutes then rwho assumes the machine is down, and does not report users last known to be logged into that machine. If a users hasn't typed to the system for a minute or more, then rwho reports this idle time. If a user hasn't typed to the system for an hour or more, then the user will be omitted from the output of rwho unless the -a flag is given. FILES
/var/spool/rwho/whod.* information about other machines SEE ALSO
finger(1), rup(1), ruptime(1), rusers(1), who(1), rwhod(8) HISTORY
The rwho command appeared in 4.3BSD. BUGS
This is unwieldy when the number of machines on the local net is large. Linux NetKit (0.17) August 15, 1999 Linux NetKit (0.17)
