comment Do CNAME records overrule A records?
@Jeff, you're right. I think it's just a typo in the question, that's why I asked for verification.

comment Do CNAME records overrule A records?
To get it right, you mean you're gonna swap foo.com into being alias for www.foo.com, correct? The last example is a bit confusing. And as @Avery said, if you need 301, then that's not really DNS stuff.

comment Running php scripts from secure location
If you deny access to your scripts you won't be able to access them. That's what deny is for. Don't do it, and you should be fine. And now seriously, why do you need the scripts to be non-accessible?

comment How to give user permissions on ubuntu server?
Normally what you want is achieved by a chrooted SFTP only setup or some restricted shell like rssh. Do you have to stay with a less secure FTP setup?

comment Migrating a subdomain to a subdirectory, whilst running on a separate server
In that case it should work. Though I think it's not a very elegant and fail-proof solution, so you should weigh the consequences of such a setup in comparison to staying with a separate ecommerce subdomain.

comment SSH Connection Refused - Debug using Recovery Console
From what I get he's using a recovery distro, so basically full access to the filesystem while the original system is offline. Maybe I misinterpreted this part though: "but I do have access to the filesystem using a recovery console". Ole could clarify this.

comment SSH Connection Refused - Debug using Recovery Console
I suppose the asker has no access to interactive shell, right Ole? He would have to wrap this command in some dummy script run on system start and log the output.

comment wireless router on LAN
A side note here. Before plugging it in, see if it's OK with your IT staff/internal policies. Technically this shouldn't be a problem.
