RE: [leaf-user] Difficulty assigning multiple IP addresses
Hi everyone! O.K. Per Charles Tom's suggestions (thank you, gentlemen), I decided to try and assign my additional IP addresses in the /etc/network/interfaces. I tried to assign them in, at first, 2 different ways...neither one of which worked. I tried: auto eth0 iface eth0 inet static address 66.60.172.201 netmask 255.255.255.0 broadcast 66.60.172.255 gateway 66.60.172.205 auto eth0:0 iface eth0 inet static address 66.60.172.202 netmask 255.255.255.0 broadcast 66.60.172.255 auto eth0:1 iface eth0 inet static address 66.60.172.203 netmask 255.255.255.0 broadcast 66.60.172.255 Etc, etc... And then a subtle variation: auto eth0 iface eth0 inet static address 66.60.172.201 netmask 255.255.255.0 broadcast 66.60.172.255 gateway 66.60.172.205 auto eth0 iface eth0:0 inet static address 66.60.172.202 netmask 255.255.255.0 broadcast 66.60.172.255 auto eth0 iface eth0:1 inet static address 66.60.172.203 netmask 255.255.255.0 broadcast 66.60.172.255 Etc, etc... But neither way worked. The good new is that Tom's suggestion of ip addr add 66.60.172.202/24 brd 66.60.172.255 \dev eth0 label eth0:0, etc works great. I can immediately ping all addresses, and ip addr lists them all. Yippee! But, I don't know what to back up (which .lrp package) to save my changes??? Also, what file(s) were modified by using this method(out of curiosity)? Finally, I have a box on the local LAN that will host a web server, and has MS Terminal Services running on that I want to be able to connect to, so my guess is that I need to follow Tom's FAQ 1c and make entries like: In /etc/shorewall/rules: #ACTION SOURCEDESTPROTO DEST PORT(S) DNAT net loc:192.168.1.201 tcp 80 DNAT net loc:192.168.1.201 tcp 1494 DNAT net loc:192.168.1.201 tcp 3389 Does this look right?

[leaf-user] Difficulty assigning multiple IP addresses
Hi folks, I'm trying (with no success) to assign multiple IP addresses to eth0 on my Bering-uClibc 2.1-rc1 box.

Re: [leaf-user] Difficulty assigning multiple IP addresses
Craig Caughlin wrote: Hey...thank you Charles Tom for the expeditious response! Let me see if I can address you both... O.K., so I gather that I need to do 2 things: 1.) Take Charles suggestion and add entries for eth0:0, eth0:1, etc., along with the entry for eth0, and 2.) Tom's suggestion ADD_SNAT_ALIASES=Yes in shorewall.conf. Is that right? No, you want to do one or the other. And you want to consider whether round-robining your SNAT is what you really want. Charles, how do I add entries as you suggest (I don't know how to do that :-( )? Here's what I have: This is a LEAF FAQ. You add one line to the eth0 interface description for each address. Example (folded to fit my mailer's default line width): up /sbin/ip addr add 66.60.172.202/24 brd 66.60.172.255 \ dev eth0 label eth0:0 The label eth0:N part is strictly window-dressing for compatibility with ifconfig; IIRC, Bering doesn't even have ifconfig so you can leave that off. Tom: If I ADD_SNAT_ALIASES=Yes in shorewall.conf, do I need to change ADD_IP_ALIASES to No or should I leave it to it's default Yes? If you add your IP addresses to your /etc/network/interfaces file then there is no point to set ADD_SNAT_ALIASES=Yes. You want to do one or the other. ADD_IP_ALIASES is completely independent of ADD_SNAT_ALIASES. You really should read http://shorewall.net/Shorewall_and_Aliased_Interfaces.html. Once I have made the correct modifications, ip addr should show all of the addresses, and I should be able to ping them all, shouldn't I???

No. The real point is that eth0:0 is *not* an interface. It is a label for an ip address on an interface.

Craig Caughlin wrote: Hey...thank you Charles Tom for the expeditious response! Let me see if I can address you both... O.K., so I gather that I need to do 2 things: 1.) Take Charles suggestion and add entries for eth0:0, eth0:1, etc., along with the entry for eth0, and 2.) Tom's suggestion ADD_SNAT_ALIASES=Yes in shorewall.conf. Is that right? Charles, how do I add entries as you suggest (I don't know how to do that :-( )? Here's what I have: auto eth0 iface eth0 inet static address 66.60.172.201 netmask 255.255.255.0 braodcast 66.60.172.255 gateway 66.60.172.205 Do I then add this for the next address... auto eth0:0 iface eth0 inet static address 66.60.172.202 netmask 255.255.255.0 braodcast 66.60.172.255 gateway 66.60.172.205 auto eth0:1 iface eth0 inet static address 66.60.172.203 netmask 255.255.255.0 braodcast 66.60.172.255 gateway 66.60.172.205 Etc, etc... Is this right? Yes, although you don't need to duplicate the gateway entry on any but the main eth0 entry. You can also do it the way Tom mentioned (adding an 'up' clause to your eth0 definition...there's almost always more than one way to do something in linux!). Also, just out of curiosity, what do you mean when you said, With the masq entry you list above, you'll be round-robining through source IP's for outbound traffic, which I doubt is what you really want.? What's wrong with that??? It means the source IP of the traffic you send to the internet (or anything else on the 'upstream' side of your firewall) will dynamically rotate between the various IP's you have assigned. You will have to be *VERY* careful that your firewall rules take this into account, and you may have problems with some applications that open multiple connections, or anything that expects your IP to be constant. Tom: If I ADD_SNAT_ALIASES=Yes in shorewall.conf, do I need to change ADD_IP_ALIASES to No or should I leave it to it's default Yes? Once I have made the correct modifications, ip addr should show all of the addresses, and I should be able to ping them all, shouldn't I??? You should be able to ping all assigned IP's, assuming the firewall rules allow it (you can allow/prevent just about anything with iptables). -- Charles Steinkuehler [EMAIL PROTECTED] --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
