vmware / centos 5 network settings

Posted: January 29th, 2011 | Author: | Filed under: centos, it, networking, virtualization | Tags: , , , | No Comments »

copied vm centos 5 machines with fixed ip settings to a different esxi server. put the machines in a vm net with an active dhcp server. the centos machines switched at boot-time to dhcp and automatically disabled the fixed ip settings. centos creates a new interface configuration file with dhcp settings. the old config file is backed. why ? the mac adress has changed ! (vmware moving). to prevent this you should probably configure the mac adresses from the old esxi system or adjust the network cfg files on centos.

snort / openvas / cain

Posted: January 24th, 2011 | Author: | Filed under: debian, it, linux, networking | Tags: , , | No Comments »

installed snort-mysql  / acidbase on debian testing and did a base configuration in 5 minutes; after installing the necassary sql files, i only had to uncomment one line in the snort configfile, set the subnet to scan, define the nic – done. always really impressive what you can do/see with this piece of free software after 10 minutes. also installed a openvas server – it seems like there is no windows client out there. nice so see that the cain & abel toolkit is still under development.   i need these systems for a demo / lecture on wednesday …

edit: the openvas-client using macports under os x works pretty good.
