Getting The Ip Using PING Command (Solaris)

Posted by antonionavarror on

Many times we need get the ip for remote, a very simple way is by using the ping command

/usr/sbin/ping

If you execute the command in the more simple option, like show below, you only get a pretty output telling if you remote host is alive.

cloud-4@:/wp/production/srvr/diag> /usr/sbin/ping cloud-2
cloud-4 is alive

Using the -s option you get more info, incluiding the ip;

cloud-4@:/wp/production/srvr/diag> /usr/sbin/ping -s cloud-2
PING cloud-2: 56 data bytes
64 bytes from cloud-2 (120.71.133.100): icmp_seq=0. time=0.098 ms
64 bytes from cloud-2 (120.71.133.100): icmp_seq=1. time=0.087 ms
64 bytes from cloud-2 (120.71.133.100): icmp_seq=2. time=0.067 ms

Released Maria DB 10.3.9

Posted by antonionavarror on

Recently the new version of Maria DB, a database manager based on MySQL, has been released. Although the original project was almost a copy of MySQL, it is following its own evolution. Here I include the main features of this version

  • Oracle compatibility (data types, sequences and PL/SQL syntax)
  • System-versioned tables and temporal syntax (e.g., AS OF)
  • Purpose-built storage engines (MyRocks and Spider)
  • Data obfuscation and full/partial data masking
  • Instant add column, invisible columns and column compression

To download this version and more information about it you can use the following link;

use — (double -) to make rm command stop parsing command line options

rm — -MGMTDB_ora_24540_20180821124431970337143795.aud

Or in this other way

rm — *.aud
