Jail proftpd user virtualmin

Mandi — Fri, 23 Apr 2010 07:43:48 +0000

This is a quick reminder on how to chroot FTP users with Virtualmin (Webmin).

What exactly is needed is the modification of the DefaultRoot setting in ProFTPd.

This can be set that in Virtualmin by browsing to Webmin>Servers>ProFTPd Server>Files and Directories, and setting the option labeled “Limit users to directories” to “Home directory”. Saving it, and clicking “Apply changes” in the upper right corner.

Restarto Apache nese serveri arrin nje limit te caktuar ngarkese

Mandi — Mon, 25 Jan 2010 11:58:00 +0000

Scripti me poshte mund te perdoret nga administratoret e serverave Linux. Sa here qe ngarkesa e serverit ngrihet mbi nje vlere te caktuar (percaktuar ne variablin: HTTPD_RESTART_LOAD), scripti ben nje restart te procesit.
Me ane te ketij scripti eshte e lehte te parandalohen crashet e serverave qe jane ne pune. Per cdo rast te sherbimit web (httpd), scripti dergon nje email (ne adresen e percaktuar tek EMAIL_ADDRESS).

Perdorimi:

Krijoni nje skedar me emer kontrApache.sh ne te cilin vendoset kodi me poshte. (/home/root/.scripts/kontrApache.sh)
Scripti duhet te jete i ekzekutueshem: chmod 775 /home/root/.scripts/kontrApache.sh
Krijoni nje crontab (crontab -e per te edituar crontab) ku te therritet ky script cdo x min. Psh: */2 * * * * sh /home/root/.scripts/kontrApache.sh >/dev/null 2>&1

Meritat per scriptin:
