 Posted: Thu May 30, 2002 7:05 pm Post subject: multiple ip's on the same computer |
 |
|
| I have 8 ips that I would like to put on 1 system. To offer the few shell users I have more hosts to irc and other things from. I know its going to be alias's for my eth0, something like eth0:1 through 7 (eth0 being the first one.) But I have never actually done this before. What is the 'gentoo' way to do this? I imagine it should be done in the net.eth0 script. Any help is appricaited. |

Look at /etc/conf.d/net. There's a section in there for adding aliases to an eth interface.

There is "possibly" bug in gentoo, 'cause as ip aliasing howto says, you
must add route for each aliased card so:
| Code: | /sbin/route add -host <first ip> dev eth0
/sbin/route add -host <second ip> dev eth0:0
/sbin/route add -host <third ip> dev eth0:1
etc... |
I've added it to /etc/conf.d/local.start and now all works nicely

it has:
#alias_eth0="192.168.0.3 192.168.0.4"
and
#broadcast_eth0="192.168.0.255"
#netmask_eth0="255.255.255.0"
I have 7 more ip's I want to add to this computer. Ive got the main ifconfig lines setup. they work fine with the first ip. What do I do here to put the other 7 in. I mean, what is the .3 and the .4 is the .3 the eth0 ip and the .4 the new alias? |

Change that to:
| Code: | alias_eth0="192.168.0.3"
alias_eth0:1="192.168.0.4" |
and it *should* work. Away from my Gentoo box at the moment, so I can't test it.

| But the ip for eth0 is set on the main ifconfig line up above? do I need to set that again? |

No -- just set it once. alias_eth0 should be your second IP address, alias_eth0:1 your third, and so on. (again, I haven't tested anything beyond two IPs on the same computer, so please let us know if this works)

Its easier than all of that
| Code: | | alias_eth0="IP IP IP IP" |
It is a space separated list of ip's to create alias's from. So that one above would create eth0:0 eth0:1 eth0:2 and eth0:3 each with those ip's specified in the space delimited variable. Quite simple now that ive got it working. I like gentoo more and more every time I find something like this. |
