Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

'm trying to use the ntpdate command to update my systems local time.
I've run into a few problems: (Running SolydX-64 home edition - debian testing)
The first was the error message: socket was already in use ...
(Solved by disabling ntp service and then shutting it down.)
Next the command appeared to hang when issued from a command line.
(Solved by opening 123 tcp/udp port to incoming and outgoing traffic.)
Now the problem is this error message: no server suitable for synchronization found
My first attemp was:
ntpdate -u ntp.ubuntu.com
9 Feb 14:19:04 ntpdate: no server suitable for synchronization found
Second attempt: I thought perhaps I was being blocked from using the ubuntu server so I tried a local time server running on a smoothwall firewall. (The ntpdate command has run successfully in the past using a a smoothwall time server - different version.)
9 Feb 14:23:06 ntpdate: no server suitable for synchronization found
A third attempt: connect to public server using an absolute IP address with some parameters that appeared to solved the
problem for other folks.
ntpdate -u -b -t 4 -p 4 126.96.36.199
9 Feb 13:03:50 ntpdate: no server suitable for synchronization found
A different approach: use ntpdate-debian which using the confg file for ntp by default. (The thinking here was probably the default config file for ntp should be generic enough to work in most environments.)
If at first you don't succeed try try again ...
Unfortunately I can't think of any other approaches to solve the problem ...
Could someone please try these commands on their system / network and see if you receive the same error message:
no server suitable for synchronization found
Thank you in advance for any advice / suggestions offered to solve this problem.

Thank you yongitz: (Server dropped: strata too high) seems to be the problem ...
Seems odd that every server I chose has too high a strata. Would you by chance know how to change the configuration
of the (smoothwall) time server? I can always post on the smoothwall forum but it would be nice to solve the problem here at LQ.
Searching now for a how to ...
Thank you to all you who replied to this thread. The smoothwall time server (192.168.0.1) has a problem
synchronizing with public time servers which explains the error message: (Server dropped: strata too high)
My difficulties with connecting to public time servers also seems to be related to the smoothwall firewall.
It doesn't recognize (authenticate) certain systems after they reboot.
It is not my intention to criticize the smoothwall project, I'm using a release candidate and problems are to be expected.
I believe it's a important initiative whose value will be appreciated by a wider audience as time goes by.
