I have two Linux machines, ( red hat 5.3 )

my question:

is it possible to verify the date & time on remote Linux machine without use ssh/rsh/ntp?

or maybe there is other tool for that?

If you can't use ssh/rsh how are you running the mount command ? – Iain Nov 17 '11 at 19:42
Why aren't you using NTP to keep the computer's clock synced? – Chris S Nov 17 '11 at 19:45
I cant use the rsh/ssh because security , but I have ping to the other machine and I can mount to the other machine , but please I cant use ssh/rsh please advice ??? , – Diana Nov 17 '11 at 19:45
@Diana: You have asked quite a lot of very basic questions. You really should speak to your manager about getting some basic training – Iain Nov 17 '11 at 19:56

You can use the rdate or ntpq program to easily query a remote machine running the appropriate daemon:

$ ntpdate -q; ntpdate -q tick; ntpdate -q tock
server, stratum 2, offset 0.006155, delay 0.04842
server, stratum 2, offset 0.006039, delay 0.04832
server, stratum 2, offset 0.006214, delay 0.04837
17 Nov 14:52:24 ntpdate[29211]: adjust time server offset 0.006039 sec

$ ntpdate -q tick
server, stratum 3, offset 0.004005, delay 0.02576
17 Nov 14:52:32 ntpdate[29212]: adjust time server offset 0.004005 sec

$ ntpdate -q tock
server, stratum 3, offset 0.003864, delay 0.02580
17 Nov 14:52:40 ntpdate[29353]: adjust time server offset 0.003864 sec

If you are trying to ensure your clocks are synced, you should set up NTP.

because security reson I cant use ntpdate.... sorry – Diana Nov 17 '11 at 20:10
Well, that's the Correct Way to do it. If you are blocked from doing so because of your security policy, that needs to be addressed by talking to your security department and explaining the reason for your exception. – MikeyB Nov 17 '11 at 20:18
@Diana Sounds like you're being put in impossible situations. You have basically no access to a server, but you need to do something administrative on it. Either you need some administrative privilege, or you shouldn't be responsible for it. – Chris S Nov 17 '11 at 20:20
