How to Install DST Update on RH9


I'm new to Linux. I need to install the 2007 DST update, but I'm confused by the different approaches on the posts and Google sessions I have seen. So far I have typed

zdump -v CST6CDT | grep 2007

to verify that the machine is not updated. It is not.

I'm in the central time zone. How do I install the update? Thanks!

Since RedHat 9 is obsolete, I'm not sure if there will be a reliable way to do this. What instructions did you find?

Your profile says you also have FC6 and RHEL4---why not simply put RH9 out of its misery?

I typed up2date tzdata to do the RHEL4 and FC6 machines. This doesn't work for this RH9 install.

The DST update instructions for RH9 are varied but basically go something like this:

1. Download the tzdata2007x.tar.gz file.

2. Extract the file.

3. Use zic to create an appropriate new zoneinfo file(s) directly.

4. Type zdump -v CST6CDT | grep 2007 to see if the DST patch has been applied.

Even after typing zic man, I don't know how to correctly use zic because I am still learning the very basics in the Linux file system.

There's this excellent thread that may help you. It is primarily for Slackware but you can get some good hints from it.

Thanks so much for the reply. It was helpful and I did get the box updated. Here's what I did:

1. Downloaded the tzdata2007c.tar.gz file from /pub/ at elsie.nci.nih.gov.

2. Extracted the tar.gz file:

gunzip tzdata2007c.tar.gz

tar -xvf tzdata2007c.tar

3. Used zic to create the new zoneinfo file:

zic northamerica

3. Typed zdump -v CST6CDT | grep 2007 to confirm that the DST patch had been applied. Results:

CST6CDT Sun Mar 11 07:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 CST isdst=0 gmtoff=-21600
CST6CDT Sun Mar 11 08:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 CDT isdst=1 gmtoff=-18000
CST6CDT Sun Nov 4 06:59:59 2007 UTC = Sun Nov 4 01:59:59 2007 CDT isdst=1 gmtoff=-18000
CST6CDT Sun Nov 4 07:00:00 2007 UTC = Sun Nov 4 01:00:00 2007 CST isdst=0 gmtoff=-21600

Now if I can figure out how to move everything off that RH9 box to a new FC6 box...

Excellent, this post helped me get my RH9 box that has no internet connection updated. My problem was finding the darn file to put on my windows FTP server that the RH9 box could reach!

Edit, worked for Suse too.

Ok, this post has been more helpful than most, but I can't even get zdump to work on my RH ES 3 server. It gives me a bash error. I have never used Linux before and I'm banging my head on the keyboard. That works just about as well as anything else I've tried. LOL I need to get my server updated to use the new time change dates but I'm completely lost. This server is on a closed system - no Internet - so I'm running up and down two flights of stairs trying to figure this out. Please help!

I answered my own question. There is a much easier way to do this. I used an RPM file from http://sunsite.mff.cuni.cz/MIRRORS/f...p/en/os/SRPMS/

Save it to a temp folder (I created a tmp folder in /etc)
At the command prompt, type rpm -iv and the file name
Type redhat-config-time
Check and make sure it's the correct time zone
Click ok
In the /etc folder, check the date on the localtime file. it should show the date you ran the rpm file.

I still can't get zdump to run on my system - it's simply not there. Oh well. Let's hope this works. I'll find out on Monday!

I think you're on the right track. I didn't have rpm available on the RH9 box because the rpm database was corrupt. Good luck!
