Tests After Setting Up a New Box$ hostname $ hostname --fqdn $ dnsdomainname $ python -c "import socket; print socket.gethostname()" $ python -c "import socket; print socket.gethostbyaddr('<output from previous command>')"If these aren't what's expected the problem is probably in either /etc/hostname or /etc/hosts . |

Multi-home hosts are possible, make sure that the kernel has "IP: aliasing support" built in. It appears as if you need at least one device named, for example, ethX . If you define, say, an ethX:0 and and ethX:1 then ifconfig won't show them, but if one of them is ethX then both show up OK. | ||||||||

> > | Network configuration in /etc/network/interfaces :
iface eth0:1 inet static address 192.168.1.50 netmask 255.255.255.0 | |||||||
For some reason pump doesn't like the :0 aliases so if you're using dhcp then it has to be on ethX . | ||||||||
