That's a good thought... My ISP is usually pretty good about these things, but I'll try a different port and look into their throttling policy further. Thanks!

What's an SFTP server? You mean transferring files using SSH, right?

If all 20 users are logged on at the same time and doing something crazy, you might have a problem. If it's just one or two users uploading files from time to time, the SSH server (sshd) that's already running in the background will take care of them just ok. There's no such thing as a separate SFTP server, it's built into the sshd.

But do you really want to give system accounts to all of your clients? At the very least, search the web on how to create chrooted user accounts that can only access SFTP.

What about sftp server? I will need to open at least 20 sftp accounts for my clients (btw. is there a way to do it without sftp server?).

Adding in the mb_language('en') call did the trick. We are using multi-byte for future friendly expansion, if and when we move to supporting more languages, etc.

Thanks for the pointer!

Click on your Linode, click on the config profile, choose "Latest Paravirt" from the kernel drop-down, save, and reboot. Done.

Already tried that - see original post:

mb_send_mail() calls mb_language; thus as a wild stab in the dark I'd say that you're defaulting to uni (and hence UTF-8/Base64 encoding).

You could either explicitly set the language to English (and have your emails from mb_send_mail sent as quoted-printable); or just use plain old mail().

Could you share your whole worker config and how you setup fastcgi?

It isn't much.
Note that I don't consider myself an expert by any way, it simply works Good Enough For Me (tm). You will need to pay attention to your rewrite and/or redirect rules so /WhateverFakePath/ is exempted from them.

Code:

<IfModule mpm_worker_module>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
ThreadStackSize 2097152
</IfModule>

EDIT: Heh, seems that in the meantime these very values appeared in mpm_worker docs as an example.

Code:

FastCgiConfig \
-idle-timeout 120 \
-initial-env PHP_FCGI_CHILDREN=24 \
-initial-env PHP_FCGI_MAX_REQUESTS=500 \
-killInterval 100000 \
-listen-queue-depth 300 \
-maxClassProcesses 1 \
-singleThreshold 0
# You will need to pay attention to your rewrite
# and/or redirect rules so /WhateverFakePath/
# is exempted from them.
AddHandler php5-fastcgi .php
Action php5-fastcgi /WhateverFakePath/php-cgi
Alias /WhateverFakePath/php-cgi /usr/bin/php-cgi
<Location /WhateverFakePath/php-cgi>
Order Deny,Allow
Deny from All
Allow from env=REDIRECT_STATUS
Options ExecCGI
SetHandler fastcgi-script
</Location>

Works cool, except for one little PITA you can read about in this thread - that is, a "graceful" Apache reload isn't so graceful, and kills all PHP scripts executing at that very moment sending HTTP 500 to users. With currently available FCGI handlers for Apache there's no workaround, unless one prefers using mod_fcgid and php in "dumb handler" mode without APC.

You could potentially run Linux-VServer inside your Linode, it might not be quite what you're after - but it would allow you to split a single Linode into several virtual servers.

Thanks for the replies guys, I've upgraded to the next Linode stage now, and still have one of the sites disabled. The amount of traffic to the site hasn't changed, so maybe this will be enough.

I'm looking into optimizing things now while it's back up. Do yous know of any good resources (online, or even books!) I should start with?

Thanks again for the help!

Hits and visits are completely different beasts. 2,000 hits a day calculates to less than 2 per minute on average, while 2,000 visits a day would amount to dozens or perhaps hundreds of times more.

Sorry, I think I may gotten confused alright quoting stats, to clarify:

In the last month:

53,675 visits: 1,731.45 Visits / Day

This would make sense except in the instances in which you have a system that doesn't need all the RAM that is available to that instance, but that you would still like to keep separate from other instances... I guess Linode doesn't quite fit what I'm looking for.

Thanks for the quick answer.

It's not currently set up for this (nor will it be).

There are more resources involved than just RAM. A 360 split into 5 instances might only consume 360 megs of RAM, but it would consume 5 times as much CPU, and increase disk contention significantly.

I'm looking into switching all of my servers to Linode. The thing is I have a couple of servers I like to have separated that only require 64 megs of ram. My question is... Is it possible to buy a Linode (say the 360 one) and split it into 5 72 meg instances or is Linode not currently set up for this?

Thanks in advance

Does Linode name servers support TSIG or something similar to verify server identity?

Bind is spamming my syslog with "xxx allows updates by IP address, which is insecure" message.

Only the first time; if you're constantly adding/removing linodes, the credit sitting in your account would cover it, and the net amount pulled from your credit card would end up being closer to the pro-rated amount.
