Use rsync to update patches

JosephS · 01-06-2008, 03:57 PM

I've been reading resources for rsync on the web as well as man rsync.
A lot of this is new to me.
I want to use rsync for updating patches.
I have a home computer, using Slackware 12.

I still have questions:

How I set this up on my computer to download new updates?

What is the difference between using ssh and a rsync daemon; which would be
more secure?

Appreciate help.
Thanks

Several solutions will be found in this topic.

Good luck.

In addition, you may want to look at Alien's scripts, including rsync_slackware_patches.sh.

Thanks.
I tried Alien's script.

Is there a way with rsync to list new patches that are downloaded:
When I rsync my patches directory with the source for patches on the net it will update it, but I also want to know which are the new patches that were downloaded as well?

I don't understand what you mean there - when that script of mine finds new patches it will show the new ones.

For instance, the latest addition to the Slackware 12.0 /patches directory resulted in this email (I run the script every night in a cron job so that the script's output gets emailed to me)

Code:

[rsync_slackware_patches.sh:] New patches have arrived for Slackware 12.0 !

Yes, you get email as Eric has responded.

I have one that directs rsync output to a file that I'll share. Here it is

Code:

#!/bin/bash
# <snipped>
DEST=/home/al/install/build_sw12/stuff
echo "+--- rsync started: $(date) ---+" >> ~/rsync_sl_bldscr_mirr_log.txt
# rsync command next
(cd $DEST && rsync -lptrv --progress --delete ${R}::${S}/${V} .) >> ~/rsync_sl_bldscr_mirr_log.txt
echo "+--- Rsync completed with $?: $(date) ---+" >> ~/rsync_sl_bldscr_mirr_log.txt

>> ~/rsync_sl_bldscr_mirr_log.txt

3 lines with those that is the part that directs STDOUT to a file (logs rsync activity to a file).

(begin date stamp, rsync output logged, rsync has ended date stamp)

I use Eric's rsync scripts.

One modification I made to the patches script was not to delete files. The simple reason is that occasionally a patched file introduces a bug. By not deleting files I can revert to the previous version. Samba (3.026a I think, but my memory is fuzzy tonight) was a recent example. I no longer could access Samba shares but could read Windows shares fine. I reverted to the previous version. The bug was not my imagination because soon thereafter another patched version of Samba appeared.

Wow, i was missing this post.
What a great script Alien Bob, Thanks!
@op: Here's another thread you may want to take a look.

Thanks for replies.
Sorry. I'm not familiar with scripts so I couldn't tell from reading the script what it was going to report. I don't think I had any new updates when I tried the script; that's why I didn't see an output like Alien Bob described.
I found this output:

Does No change detected in the CHECKSUMS.md5 file. mean there are no new updates?

Can I edit this: PKGONLY=0to stop downloading the source. I keep forgetting the -p option?

Indeed

Yes you can change that line in the script and it will no longer download the package source.
