Hi,
I have some problems configuring an Apache2 webserver to use https and
support multiple virtual servers.
From what I've understand you need to have at least one entry for
NameVirtualHost but as I have a dynamic IP from my ISP I can't set it.
I've read that you can use variables with Apache2, and so I thought I'd
get the current IP from somewhere and use it in the conf file.

My question is just How?
Where can I get the current IP of my internet connection (eth0) and how
can I use it in the httpd.conf file?

Thanx

.... 'programmatically'?? via a CLI? maybe start at "man ifconfig"

You can get it from /sbin/ifconfig. However you need a IP for each!
https host, using catch all certs and alike completely defeats the
purpose of https, which relies among others on a reverse DNS lookup,
making dynamic IP mostly useless.

You can use wildcard NameVirtualHost * and <VirtualHost *> sections for
http, but I doubt if it would work for https.

Hey,
I am a newby, I plea guilty of that. But getting the IP address from
ifconfig eth0 is familiar too me.
My question is howto get the information presented there into my
httpd.conf file.
I'm sure you can do it with some fancy regexp in combination with grep.

The other question is more of a "is it possible", can I use the result
from this in my conf file, and how?

Thank for your effort.

Yeah, you're right. It won't work, that's why I'd like to get the
current IP into the conf file.

I can get the IP from ifconfig eth0 but there's a lot of rubbish there
too that I need to get rid of. Some fancy regexp in combination with
grep is my guess, but I'm not even close on having it working.
And another issue is how to use the result in the httpd.conf file.

Thanx for your effort

Are you asking how to *redirect*?

for example:
ifconfig | grep 'inet\ addr' > somefile

This doesn't exactly work, however, b/c you are interested in extracting
only the IP addr of eth0, so you would need to modify command.

I'm pretty sure you would need to use 'sed' to extract the IP address
and you might have to use some fancy way of inserting it exactly where
you want into your .conf file.

No, I'd like to have some (or at least one) secure site(s) on my
Linux-box where I can access webmail and other stuff that I need to log
on in order to get. Sending the password without any encryption isn't my
idea of secure computing.

I've thought about doing it this way in the conf file:
---snip-----
SetEnvMyIP 213.204.63.63 #( get from system )

NameVirtualHost env=myIP
<VirtualHost 192.168.0.1 env=MyIP>
---snip-----

What do you all think? Will it work?

Comments, plz!
