Is the time right on the forums?
When it says it is 12:48 on the forums it says on my computer 12:07.
It may just be me but i do look at the time users post and it would be helpful to know when they were posted exactly.
Thanks :)

Isn't it horrible how something like that is liable to happen and kill all of those people. I mean there wasn't much that the countries could do in preparation for something quite so severe. :(
I don't think it would have been worse on land though, because it would be more localised and the Tsunami would never have occured.
On the other hand it is quite remarkable how the world is uniting in donating aid and helping out the affected.
Please donate to a charity helping to combat the diseases and hunger caused by the awful power of mother nature. ;)

| Suse 9.2 and SATA drives |

How can I use my SATA drives under Suse 9.2 ? Suse finds all other IDE drives without any problem, but I am missing 2 drives. I have winXP on 1 IDE drive and Suse on another IDE drive. Suse only see itself and another IDE drive (not the XP). Any suggestions?

Looking for a ftp client to go with Suse 9.2 pro. Have tried the BearFTP thingy that comes with it, but it screwes up my start menu... :S Any suggestions? Need to have a graphical frontend. Have tried running FlashFXP (which is the favourite... ;) ) under wine, but it seems to hang and ends up useless.

| simple automated backup of apache (your websites) |

This will create a dated and compressed tar backup once a week, of everything in /usr/local/apache into the /backup/ directory.
This certaintly may be useful considering the amount of worms floating around at the moment (like Santy, which overwrite all php and html files with rubbish)
** this assumes you have your websites in /usr/local/apache as per the apache/mysql/php compilation howto in this forum, obviously, if they are not in that path, edit the path to point to your websites/code **
(thanks Kobras for advising me here)
Simply do as follows:
Code: vi /etc/cron.weekly/apache.cron
ok now paste the following into this blank file
Code: #!/bin/sh
/bin/tar -jcf /backup/apache_backup_`date | awk '{print $2}'`_`date | awk '{print $3}'`_`date | awk '{print $6}'`.tar.bz2 /usr/local/apache/ 1&>/dev/null 2&>/dev/null
save the file and now make it executable
Code: chmod +x /etc/cron.weekly/apache.cron
ok, create the /backup directory
and test the script (to see that it works)
Code: /etc/cron.weekly/apache.cron
if all goes well you should see a file like this in your /backup directory
Quote:[root@www root]# ls -alsrxh /backuptotal 140M
140M apache_backup_Dec_29_2004.tar.bz2 4.0K .. 4.0K .
ok that's it ! all done,
now you may want to write another script to 'auto delete' a file if older than two weeks, otherwise your hard disc may soon fill up with backups.
cheers

| How to block local users ports and ips |

Want to block a local user to access a specific port or a specific ip ?
linux-noob.com will help you how to do that :
[root@test tmp]# id test
uid=503(test) gid=503(test) groups=503(test)
[root@test tmp]#
(look at uid= and gid=)
How to block a local user to access any outside ports ?
Code: iptables -t filter -A OUTPUT -p tcp --dport 6667 --match owner --uid-owner 503 -j DROP
(you may need to change tcp to udp or icmp and --uid-owner to other uid)
How to block a local group to access any outside ports ?
(lets find group 'users' gid by doing grep -i users /etc/group)
Code: iptables -t filter -A OUTPUT -p tcp --match owner --gid-owner 100 -j DROP
For blocking just specific ports just add --dport port or --sport port after -p protocol
Code: iptables -t filter -A OUTPUT -p tcp --dport 6667 --match owner --uid-owner 503 -j DROP
Code: iptables -t filter -A OUTPUT -p tcp --dport 6667 --match owner --gid-owner 100 -j DROP
How to block a specific range of ports ?
Code: iptables -t filter -A OUTPUT -p tcp --dport 1:1024 --match owner --uid-owner 503 -j DROP
(you may need to change the range 1:1024 (all ports from 1 to 1024) and the uid)
How to block a specific ip destination or source or a specific class (a 256 ips class) on all protocols and ports or to specific port(s)?
destination :
Code: iptables -t filter -A OUTPUT -d 199.9.9.9 --match owner --uid-owner 503 -j DROP
source :
Code: iptables -t filter -A OUTPUT -s 199.9.9.9 --match owner --uid-owner 503 -j DROP
full class :
Code: iptables -t filter -A OUTPUT -d 199.9.9.0/24 --match owner --uid-owner 503 -j DROP
Code: iptables -t filter -A OUTPUT -s 199.9.9.0/24 --match owner --uid-owner 503 -j DROP
specific destination or source specific ports or range :
Code: iptables -t filter -A OUTPUT -d 199.9.9.0/24 --dport 6667 --match owner --uid-owner 503 -j DROP
Code: iptables -t filter -A OUTPUT -d 199.9.9.0/24 --dport 1:1024 --match owner --uid-owner 503 -j DROP
(you many need to change tcp to udp or icmp and --gid-owner to other gid)
(the ips and ports used here are just examples)
Thats all for today.
