gg servers status
Gadu gadu seems to be down almost every day, sometimes I’m not sure if it is my net problem, or gg servers (but maybe it’s time to get accustomed that gg is down 
).
I made some script which checks the avability of gg servers, just for fun, and not googling for this.
If you wan’t to try - don’t hesitate: gg_status.txt
Is evo X better than evo IX?
Just take a look, maybe Evo X looks nice, but only Evo IX does the job!
security tip: mail me if sb logs to root
It should work simple, it should be fast, it won’t be persistent unless you use a root account to everyday work. It make you system a little bit more secure, it can help you, when it is to late to recover log files
just edit .bashrc root file, and put there sth like this:
echo ‘ALERT - Root Shell Access at ServerName on:’ `date` `who` | mail -s “Alert: Root Access from `who | cut -d”(” -f2 | cut -d”)” -f1`” any@mail.com
c-media ac97 audio device problem with windows xp sp2
My friend asked me to reinstall his windows xp, because it us unstable. I noticed that almost all capacitors on his motherbord are damaged (bulged). His CPU was Athlon XP. I had an old ECS K7S5A motherbord, so I suggested him to change the MB. As he agreed, I started to install the windows xp (license connected to his old MB, but who cares ). As the system with SP2 didn’t see the audio. There was an exclamation mark, and the information of code 10 (microsoft explanation):
“If the device has a FailReasonString value in its hardware key, that string appears as the error message. The driver or enumerator puts this registry string value there. If there is no FailReasonString in the hardware key, you receive the following error message:
This device cannot start. (Code 10)”
Ok, but why oryginal drivers from ECS site does not work. I googled a lot, many same questions, but no answers (just some tips, but always useless). I didn’t give up. After almost 6 hours of fight, i tried to install the realtek ac 97 drivers (instead of c-media). And this succeded :). If you have same problem… just download: genuine realtek ac 97 driver, and that’s all
Changing Office 2003 key, and so on…
Yesterday I did a corporate cd image, sth about easy install to all our client computers (same for everyone), I tried to guess, how to change an office 2003 license keys, as they are encoded in registry. The most difficult was office 2003. But I googled a great tool Win Key Finder (it has an option to change keys).
You can easly download an acctual version (1.73_RC2) from my mirror.
Apache Server Token changing
My friend (xoff) showed me his trick about ServerToken changing. It looks nice, and can be a little bit more secure (for sure it kills the robots) than line simply showed by my apache server:
Apache/2.2.6 (Unix) mod_ssl/2.2.6 OpenSSL/0.9.7m mod_apreq2-20051231/2.6.0 mod_perl/2.0.3 Perl/v5.8.7………
Can be limited by changing in your apache.conf:
ServerTokens Full
to:
ServerTokens Prod
note that if no option is set the default is Full (read more at apache documentation)
But if you really want to have somethins different, just use mod_security module, and add
SecServerSignature “someCOOLapacheName v1.1.1.1.1.1.0″
note that you have to set ServerTokens to Full option to see the effects of SecServerSignature.
RSA II, funny thing
Today I tried to solve the problem with RSA II card (sometimes it does not show anything), and I find sth like that on IBM Support site:
Symptom:
When a user logs in remotely to the IBM Remote Supervisor Adapter (RSA) Web interface and launches the remote control option, an applet window will open but no graphics will be displayed on the window. There may be repeated attempts to launch remote control (graphics), but no video data will be displayed.
Solution (the “funny” one):
It is assumed that the RSA and the server were restarted (i.e. rebooted) in order to resolve this issue, but the problem still persists. To resolve this issue, power must be removed from the RSA. This usually requires removing power to the entire system (i.e. unplugging the box). Wait about 20 seconds, then restore power to the system and restart it. This will clear the issue discussed above.
Sorry, but it smells like windows, and “what if windows were a car”:
Occasionally your car would die on the freeway for no reason. You would have to pull over to the side of the road, close all of the windows, shut off the car, restart it, and reopen the windows before you could continue. For some reason you would simply accept this.
I think that power off and power on (ohhh sorrry, not only power on and power off, just pull off the cables!!!) - is no solution (notice that RSA card is used only if the operating system does not response - so for me it is critical situation, and usually if you have no phisical access to the server) . I writed and e-mail to the IBM support, to fully solve the problem.
IBM ServeRaid 8i, 8k, 8k-l problem with making array bigger than 2TB
Today, I started configuring server IBM System x3650, with 6 drives 750GB.
I boot up from ServeRAID support CD to configure the array in RAID 5, and noticed that I can make only 2TB logical drive instead of 3,5TB expected (6×700GB-1×700GB for parity).
I download fresh firmwares (and addicionaly noticed that IBM SAS Drives has a critical update. And there was no difference. I noticed that ServeRAID Support CD use kernel 2.4, and try not to configure array from support cd.
By entering controller BIOS (CTRL+A), you can easly configure array how big you want :). I send an information to IBM support, they replied that in next verison of support CD kernel 2.6 will be used.
