ps on Solaris -- zone tip

This is a mini-tip. I was running a ps command to see if snmp was running on a particular host and got back way too much information:

#  ps -ef |grep snmp
   root   938     1   1   Jan 17 ?        2906:56 /usr/local/sbin/snmpd -r
   root 13536     1   0   Jan 25 ?          59:46 /usr/local/sbin/snmpd -r
   root  2545     1   0   Jan 17 ?          19:32 /usr/local/sbin/snmpd -r
   root  6050 26619   0 08:48:36 pts/2       0:00 grep snmp

At a glance I wanted to know what host the command was running on and it wasn't obvious, so I looked at the man page for the ps command and sure enough there was a new option that I didn't know about -- the "Z" option, which tells you which zone it's running on.

Very nice job SUN! Here's the new command:

# ps -efZ |grep snmp
  global    root   938     1   1   Jan 17 ?        2907:03 /usr/local/sbin/snmpd -r
   host1    root 13536     1   0   Jan 25 ?          59:46 /usr/local/sbin/snmpd -r
   host2    root  2545     1   0   Jan 17 ?          19:32 /usr/local/sbin/snmpd -r
  global    root  6189 26619   0 08:50:32 pts/2       0:00 grep snmp

Upgrading Solaris on hosts without a DVD or CDROM drive

http://docs.sun.com/app/docs/doc/817-5504/6mkv4nh96?a=view

This is the easiest way to upgrade hosts that don't have a local cdrom or DVD disk.

One thing to remember is that the two hosts need to be on a subnet that have no other tftpboot servers...
