vmware / centos 5 network settings

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.

routing mail with exim4 to different mailservers

must do this to migrate mailboxes from exchange2k3 to exchange2010
i prefer postfix to do mta stuff but here we got exim4 …

the transport still exists (remote_smtp > 30_exim4-config_remote_smtp)

router:

special_routes:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
host_find_failed = defer
same_domain_copy_routing = yes
route_data = ${lookup{$domain}lsearch{/etc/exim4/routes}}

/etc/exim4/routes :
email@dumb.com: newmailserver.com
dumb.com: oldmailserver.com

snort / openvas / cain

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.
