RE: Newbie Q: Is ispCP Omega the right tool for me? - pete - 12-17-2009 10:33 AM
I followed this suggestion: Create a subdomain webmail for all your domains to access the webmail.
I was hoping it would allow me to access webmail using a link such as:
http://webmail.elegancenz.co.nz
To test this, I added webmail.elegancenz.co.nz to my hosts table and then activated the URL above, but with no luck.
Do I need to restart something?
I also wonder if I should change the DNS from my registrars DNS to my VPS? Updates might propagate quicker this way. Is this common practice or a big no-no?

You'll probably need to restart Apache if the instructions didn't include that step.

It really depends on their TTL (think of this as the time the info stays in cache). In general, their DNS service will be more distributed and stable than that single server. If your sites are going to be small and low-traffic, there should be no harm in using it to serve DNS.

I did restart apache2. I was a bit puzzled that everyone recommends to restart it by typing "apache2 restart" which didn't work for me (and instead gave me a list of command options which suggested I use "apache -k restart", but this didn't work either).
The way I got this working (I believe) was:
Code:
root@serifos:/# service apache2 restart
* Restarting web server apache2 ... waiting [ OK ]
root@serifos:/# root@serifos:/# service apache2 restartHowever, after doing this the url http://webmail.elegancenz.co.nz simply gets me to the normal website rather than webmail.
Apart from changing the DNS template as the guide recommends, here is what I planted in the file /etc/ispcp/apache/working/00_master.conf (using the correct IP instead of 1.2.3.4):

On Debian and Debian-derived distros, it's "apache2ctl". Most others simply use "apachectl".

While that is the right place to make sure your changes aren't overwritten, you might not have had it added to the Apache running copy.
Make sure that's also present in the Apache copy of the file.

Now that all has been up for a while, I have a new problem:
Every now and again, I get errors in outlook when trying to access my pop3 mailbox.
I have no idea where to look for what is going on, but I'm a bit worried that it might be caused by an external attack. perhaps the system isn't secure enough. But surely, there should be some logs that would give me a clue.
Rebooting the virtual server normally resolves the issue.
Where should I go and look first?

I discovered that my problem had to do with a postfix memory allocation error which prevented it from accessing the aliases.db.
As it turns out, I'm using way more memory than is allocated form me by the virtual machine hosting service I'm using (limit is 500MB). I checked what is running using the top command and found that I have two large apache2 instances, each clobbering 277MB. Also, MySQL should have very little work to do but still uses 144MB.
Am I doing something wrong? Can I force these processes to be more frugal?
