Toto je vystup, zaujima ci uz disk treba vymenit alebo to este prezije alebo ako este nieco dotestovat?

Sítě / Re:postfix, domena a lokalna siet

« kdy: 19. 07. 2012, 19:50:03 »

toto je len pre par lokalnych klientov na sieti. Takze staci len domena v ramci lokalnej siete. Podla toho co hovorite, bez bindu sa neobidem? Ja to chcem vyuzivat len na preposielanie mailov...aby si to niekto zadal vo svojom emailovom klientovi a preposielalo to do netu.....
Neviete mi napisat par jednoduchych a dolezitych krokov....lebo takto neviem odkial sa mam odrazit....

Sítě / Postfix, doména a lokálna sieť

« kdy: 19. 07. 2012, 19:13:48 »

Zdravim na sieti mi nebezi nijaky dns server a potreboval by som vyuzivat sluzby mailoveho servera. Je potrebny aj dns server, ked chcem aby mi fungoval postfix?
Podla tohto manualu, je to hned v dalsich krokoch: http://wiki.debian.org/Postfix
a este nikdy predtym som neriesil dns ani mail na serveri.
Keby ma vedel niekto trosku nasmerovat bol by som velmi vdacny, dakujem.

Ive just got recommended cacti scripts - scgrab.
http://code.google.com/p/scgrab/

But I have problem to run it.

My installation:

1. I installed: cacti, python.

2. Download paramiko to your server: wget http://scgrab.googlecode.com/files/paramiko-1.7.6-AES-patched.zip and unzip.

3. Then I downloaded patched paramiko and installed it using this command:
python setup.py install (you have to be in folder where you extracted paramiko).

4. Then I downloaded scgrab: wget http://code.google.com/p/scgrab/downloads/detail?name=scgrab-2011-02-26.zip&can=2&q= and unzip it.

5. I copied it from downloaded place to /usr/share/cacti/site/scripts. It looks there like this: /usr/share/cacti/site/scripts/scgrab/scgrab.py

6. I set permissions for log and cache directory: sudo chmod -R a+rwx /usr/share/cacti/site/scripts/scgrab/log
sudo chmod -R a+rwx /usr/share/cacti/site/scripts/scgrab/cache

7. I generated keys on my server using this command: ssh-keygen -b 1024 -t dsa -C "monitor system" -f monitor
It created two files: monitor and monitor.pub.

8. I copied monitor to /scgrab/auth/keys

9. I uploaded monitor.pub to my ubnt device in ssh section(authorized keys). Also enabled ssh, port 22, enable password authentification.

10. I imported cacti templates from extracted scgrab folder. In cacti I created graph...

Problems: Graphs shows no data. In scgrab/log is this:
2012-04-16 10:40:04 - 2964: generate_cache: key file specified does not exist
2012-04-16 10:40:04 - 2964: main: data not available - exiting

Neviete poradit, co robim zle. Vyzera ze nieco s tou authentifikaciou - DSA. Nepochopil som ci treba niekde na serveri zadat meno a heslo na ssh vstup do monitorovanych ubnt zariadeni....ak ma niekto skusenosti a poradi budem rad, dakujem....
