How do I check for duplicate IP addresses in Linux?
Linux doesn’t do an active monitoring or reporting of duplicate ip, after the interface is initialized. To check for duplicate IP addresses in Linux:
Log into your server via console and from the command line run
arping -D -q -I eth0 -c 2 192.168.1.250 ; echo $?
If the above commands return 0, then no one responded to your arp request and therefore no one else is using your IP address.

How do I change a printer’s IP address in AIX?
The mappings of IP addresses to “lp” names are contained in the /etc/hosts configuration file. To change the IP address:
vi /etc/hosts

How do I view my Eclipse rsync backup logs on Linux?
The standard rsync backup script keeps a number of log files that are accessible to the system administrator. To view the log files, log into your server as root and run the following commands. You may also configure the backup script to send an email every time the backup is run.
/tmp/snapsave.log contains the output from the last successful rsync backup
more /tmp/snapsave.log
The log for a successful rsync backup will show output similar to the following:
Copy done - status=0 Number of files: 2248894 Number of files transferred: 6519 Total file size: 181.30G bytes Total transferred file size: 135.72G bytes Literal data: 135.72G bytes Matched data: 0 bytes File list size: 82.91M File list generation time: 0.001 seconds File list transfer time: 0.000 seconds Total bytes sent: 135.82G Total bytes received: 152.13K sent 135.82G bytes received 152.13K bytes 14.44M bytes/sec total size is 181.30G speedup is 1.33
A successful backup status returns a 0, while an unsuccessful one returns a non-zero value that usually can be interpreted as an error code.
- /tmp/snapsave.rsync-local.log – contains the files that were backed up or updated by rsync backup operation
- /tmp/snapsave.log – logs database suspension and snapshot operations:
less /tmp/snapsave.log
The following log file shows a successful backup and details the database and snapshot operations taking place. This is very useful for troubleshooting backup issues.
