It’s a really fustrating feature , cron keeps sending mails with the output of every job it executes.
You can disable this per job by editing the crontab file (# crontab -e) and reddirecting the stdout (output messages) and/or stderr (error messages) to /dev/null.
for stdout:
0 * * * * /path/to/script.sh > /dev/null
for stdout and stderr:
0 * * * * /path/to/script.sh &> /dev/null
Or you can globally disable it with the MAILTO variable:
# echo 'MAILTO=""' >> /etc/default/cron
If you cannot save the running config to startup-config on a cisco router/switch be sure to check your config-register, if it’s inappropriately configured the router/switch will ignore the startup-config.
The factory-default setting for the configuration register is 0×2102.
Check it by issuing a show version command in privileged EXEC mode:
router#show version

Am făcut zilele astea unpic de cumpărături, ce mai exact?
Păăăăi pentru început, după cum a observat şi Emil, mi-am luat un VPS si am mutat tot ce inseama http si webservices pe el.
De ce am făcut asta? Pentru că am prostul obicei să mă joc cu hw-ul şi cu sistemele de operare deci blogul avea mai mult downtime decât uptime. Să sperăm că lucrurile vor sta altfel acum 
.
Am mai luat două routere Cisco 1721 fiecare cu un WIC-2T şi un WIC-1ENET şi un switch Cisco WS-C2924-XL-EN pentru micul meu laborator Cisco/CCNA.
Din păcate deocamdată nu apucasem să mă joc cu ele, sper să imi fac pe săptămana viitoare.
Şi nu în ultimul rând am luat o carcasă nouă, un Antec Mini P180 pentru serverul meu (dakara). Carcasa mea veche (Un Asus ordinar) începuse să vibreze din cauza hdd-urilor de mă scotea din minţi. Sper sa revin cu un mini-review pe mâine-poimâine.
Finally took the time and uploaded the pictures from FLOSS Camp 2009 (click on the above picture to take you to the gallery).

I have at home a Linksys WRT54G router flashed with DD-WRT. I configured it a long time ago so today when i wanted to use the web interface I realised that I forgoted my http username.Luckily i still had telnet access because the telnet username stay’s the same (root). I didn’t want to reset the router back to it’s default settings because that meant i would lose all the settings that I made.
So here is how you reset your http username back to root:
1.) Telnet to the router:
telnet 192.168.1.1 (This is the default IP address, change it accordingly)
2.) Input the username (root) and password:
3.) And finally reset it:
nvram set http_username=4DBfucrfjXL6o
Here is a screenshot of the process:
