There are a variety of repositories with different software packages available which is why I like to use most of the following… Read more »

To get up-to-date malware definitions the following sources can be used: Freshclam The Freshclam binary should have been installed when you installed clamd and you should have a script… Read more »
Exporting Global Address List
I was thinking of trying to export/convert the Exchange Global Address List GAL so that I could then import this into other email client address books such as Evolution or Thunderbird. While it would be possible to do this with any language and running an LDAP search I happened upon the following micro$oft tools: csvde… Read more »
Refreshing ARP table entries
Taking an IP address down on one host: /sbin/ifconfig eth0:1 down Taking the IP address up on another host: /sbin/ifconfig eth0:1 111.222.111.222 netmask 255.255.225.0 up Use arping to update the ARP tables: /sbin/arping -S 111.222.111.222 -B So the switch should cache the new arp entry invalidating the existing one.The arping utility appears to be part… Read more »

Maybe it is just the colours but it is also useful to get a view of the memory without the caches included. yum… Read more »
Samba Client
Smbclient operates like a command-line ftp client which allows sending commands to the samba server. The following syntax worked for me: /usr/bin/smbclient ‘//anotherserver/myshare’ -D ‘mydirectory/’ -c ‘mkdir “testlog5″‘ -U ‘myusername%mypass’ I got a bit confused when some directories where list with DA rather than D but these extra file attributes appear to be: A –… Read more »
