Hello all,
I'm sorry for such a silly help.
I have 8 unix machines which include AIX, IRIX, HPUX, SGI.
I wanted a script that would compare/ check the date and time on all machine and send me a mail if some system has different date. how can i do it with a single script
It can check date and hour and if possb min.

I would be thanksful if any one could help me with this.

Regards,
Pradeep Kulkarni.

Hi Pradeep,

To get the current time of any machine, try to read the data from port no 13.

For e.g. Using telnet :

Telnet <machine name> 13

Trying <I.P Address>...
Connected to <remote host>.
Escape character is '^]'.
Mon Jul 25 18:37:04 2005
Connection closed by foreign host.

U can get the current time for remote machine.

Why not use NTP (Network Time Protocol) to maintain time on all servers? Here is a link to info about NTP on HP servers, and here is a link to NTP on Sun.

it is better to you run NTP on your UNIX hosts... and synchronize them with another NTP server on the internet, say time.nist.gov

Hello all,
Sorry for the delay in reply. i knew about NTP but i wantd a script that would post a mail to me about this information.
i did try Telnet <machine name> 13 and it works but how do i capture this data and put it in file and mail...???

Rgds,
Pradeep Kulkarni.

You could try this code :

toto=`telnet <machine name> 13`
datetime=`echo ${toto} | cut -d' ' -f10-`

Regards.
