Hi all, I have installed suse on my box and got the latest version of apache going.

I would like to know how i can assign mutiple ip addresses to my system. i.e, what file i need to add entries to???

Thanks

If you are refering to multiple IPs on same network interface then look into:
#ifconfig eth0:1

Thanks for the post nabil, yep thats what i want, only i dont understand your instruction, is IPCONFIG a file? Can you please elobrate some more as i have had linux for only 2 weeks,

OK, I have managed to assign a I.P address for my network card (eth0) and used command: ifconfig eth0:0 194.168.0.2.

I did a PING to 194.168.0.2 and it seemed to have worked, yet when i reboot Linux i loose 194.168.0.2, 100% packet loss when pinged.

please help????

Well, I think you need to make a file under /etc/sysconfig/network-scripts called "ifcfg-eth0:0" then do the ifconfig again
#ifconfig eth0:0 172.26.20.110 netmask 255.255.255.255 up

The file for eth0:0 as "ifcfg-eth0"

It would be something similar to this :
[nabil@viper network-scripts]$ more ifcfg-eth0:0
DEVICE=eth0:0
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.0.0.150
NETMASK=255.255.255.0
GATEWAY=10.0.0.1
BROADCAST=10.0.0.255
NETWORK=10.0.0.0
USERCTL=no
[nabil@viper network-scripts]$

Let me know if this work.

I tested this on a Sun Solaris 8 but not yet on Linux.
BTW: The ifconfig command is a temp thing unless the file is made and the machine can use it when rebooted.
If that does not work then don't reboot the machine until you figure it out.

I tried the above but no luck, I think SUSE has a different means of doing this: I edited rc.config to look like this:

# Number of Network cards

NETCONFIG "_0 _1 _2 _3"

# IP Addresses

IPADDR_0="192.168.0.2"
IPADDR_1="192.168.0.3"
IPADDR_2="192.168.0.4"
IPADDR_3="192.168.0.5"

#network devices

NETDEV_0="eht0"
NETDEV_1="eht0:0"
NETDEV_2="eht0:1"
NETDEV_3="eht0:2"

I used Ping and they all work. I am using APACHE and i have configured virtual hosts at each of these IP ADDRESSES. It seems to work. I get no errors at boot-up...

Do you know if the above is okay?

As you mention Apache are you setting up the multiple addresses to implemente multiple sites hosted on the same box? If this is the case its not necessary - you can do it using VirtualHosts in you httpd.conf - have a look near the end of the file.

Cheers.

Jamie I tried that but it didnt work... I made a few virtual hosts and when i pinged them there was 100% packet loss.
also the pages didn't load, i got a message: could not connect www.virtualhost.com.

When i added the IP Address to the Interface, all seemed to work well.

I need more than one IP as I am playing around with MODSSL and want to configure SSL on more than on virtual host.

you did that correctly for suse... redhat does it via /etc/sysconfig, suse uses rc.config.... and yes, you must use ip based virtual hosts w/ssl because of how ssl works...

Ricardo77uk,

I think you setup is OK, but as far as Apache using multiple IP's for the purpose of having virtual hosts is not necessary in your case. Apache has the capability to bind virtual hosts to same IP address but there are a couple of tricks to this. A typical SSL setup does not work on multiple IP's if this what's multiple IPs are for. If SSL is not your case and only need to have multiple sites running on same box with same IP then look at my http.conf file. I have few actual web sites running on same IP address.

Every else in httpd.conf is irrelevant....

This setup will allow you to run apache for multiple sites using same IP.

nabil,
that is a good example however you could simplify your virtualhost tags some by putting the common things in the global config section... however, that is a good example and like you pointed out - this does not work for ssl...

there are ways around that though but they require an http splash page...

rebby,

Thanks for your comments, but I think I tried some of that before and did not have time to debug why it did not work. Anyway: I like to know a little more about that work-around for the splash page setup for using SSL on mutiple IP's....Would you kindly post some info in reference to that.

sure...

first setup your dns like this ->

• site1.net -> 192.168.1.1
• site2.net -> 192.168.1.1
• site3.net -> 192.168.1.1
• etc...

now you want to create your key. make sure that it is very general (ie: your business and not site specific). it is best to have a verified key for this but if you just want ssl it doesn't matter. having one key for all sites is the big draw back here

now setup domain name based virtual hosts (as seen above).

in the document root of each site put your splash page or redirect (meta tag, javascript, etc.).

the link off of the splash/redirect should be to a page in the document root of the ssl site.

for example

• site1.net -> <ssl document root>/site1/ -> https://your.ip/site1/
• site2.net -> <ssl document root>/site2/ -> https://your.ip/site2/
• etc

because the ssl enable site can't do virtual hosts by domain name the site name does not matter... therefore, https://site1.net/page/ is the same as https://site2.net/page/ so be sure to use seperate directories for each site...

it's kind of a ghetto hack but it works pretty good and gets the job done w/out using a ton of ip's (some of us are limited to very few).

I found all of the above useful and the config i posted above works really well! Cheers all!

Rebby, You mentioned DNS, i am currently putting all of my IP's and Domain names in the 'Hosts' File, Is this Linux's DNS or is there another way or file?


Both of my SSL sites work perfectly on the Linux Box, does this mean they will work ok remotely?

Yep Nabil, I need multiple IP's for SSL Virtual Hosts. My Current Httpd.conf almost mirrors yours and allows me to make a HTTPS connection on 2 different Virtual Sites.

only i had to name the secure sites to:

secure.site1.com
secure.site2.com

with non-ssl virtual host entries for:

site1.com
site2.com

Could anybody be kind enough and post their Httpd.conf which has SSL V-Hosts setup?

Cheers
