If you have a look in the sample config. in the post, you should see an example path (/usr/lib/php5/20060613+lfs/xdebug.so). I can't be definitive about where it's located, as the path to the extension (and in some cases, even the name of the file) depends on the version of Linux/PHP/Apache you're using. But it's likely to be called something like xdebug.so and be located in your PHP installation's extensions directory (look for the extension_dir setting in your php.ini file to work out what the latter is).

Question...

You wrote: "Note you need to use zend_extension= to load the extension, and you should use the absolute path to the module (.so file) to do this. Otherwise it fails."

So, what is the name of the extension? Where do I find it?

Thanks for clarifying.

Thanks for clarifying.

Thanks, I know about Pastie.

Thanks, I know about Pastie. Can it be used as a repository and then accessed via an API?

Try Pastie for sharing code

Pastie is great for sharing code. It formats, and highlights.

But pdftk needs OWNER

Guest — Mon, 19 May 2008 11:20:03 -0500

But pdftk needs OWNER password and to use the method decribed above you only need USER pass.

firewall

Guest — Thu, 08 May 2008 03:01:53 -0500

Hi,
Great script - I've used it as the starter for my setup.

ShieldsUP notes that your script shows ports 0 and 1 as closed rather than in stealth mode, and also doesn't drop ICMP packets - meaning that if the machines are directly attached to the internet via ppp, or with an ADSL modem with no firewall, then they can be discovered.

Also your script doesn't handle dialup connections.

The following changes mitigates against these:

drop everything else on ppp
iptables -A INPUT -i ppp+ -p udp -j DROP
iptables -A INPUT -i ppp+ -p tcp -m tcp --syn -j DROP
iptables -A INPUT -i ppp+ -p icmp -j DROP
Explcitly deal with port 0
iptables -A INPUT -j DROP -p tcp --sport 0
iptables -A INPUT -j DROP -p udp --sport 0
iptables -A INPUT -j DROP -p tcp --dport 0
iptables -A INPUT -j DROP -p udp --dport 0
Explcitly deal with port 1
iptables -A INPUT -j DROP -p tcp --sport 1
iptables -A INPUT -j DROP -p udp --sport 1
iptables -A INPUT -j DROP -p tcp --dport 1
iptables -A INPUT -j DROP -p udp --dport 1

Spamassassin and Spam Deletion

monkster — Sat, 03 May 2008 11:03:43 -0500

"most of it gets stopped by the Postfix server using Spamassassin"

I don't think this part is right. From wiki.apache.org/spamassassin:

"SpamAssassin itself will not delete any emails. It's only a filter which reads email in, and passes that same email out, modified in some way. If you want to delete emails, or redirect emails, you need to do it in whatever program calls SpamAssassin. "

The site then goes on to explain how to set up a procmail filter to drop spam at the server, it that is what you want to do.

In your case, do you think what is happening is that Thunderbird's Bayesian filter can learn what is junk instantly because of SpamAssassin headers? Thus you can achieve your end result, very little spam in the Inbox, but all the filtering is done by Thunderbird. I don't see Postfix dropping mail on the floor. Please correct me if I am wrong.

Thank you for this mini-howto. I used it to set up Spamassassin on an Ubuntu server running Courrier IMAP in literally minutes, and it is working great. I also use Thunderbird. It is also easy to set a filter in Squirrelmail (web mail) to filter spamassassinated messages to the Inbox.Junk folder:

options/message filtering:

If Header contains X-Spam-Flag: YES then move to Junk

Thx ;)

thanks!though iptables -A INPUT -p tcp -s 0/0 --dport 80 -j ACCEPT is needed!

Thanks for the tips. Useful.

Some of the text has been

Guest — Sat, 22 Mar 2008 11:34:29 -0500

Some of the text has been eaten above... Essentially the if condition to check if there is a rake file before installing completions on entering a folder is the important part. Also removing the completions on exit is handled by the "else" and the -r.

I've also included a completion for capistrano that I use.

I'll paste again below in the hopes that it makes it this time.

cd () {
command cd "$@";
# Add enhanced completion for a folder containing a rails app and remove it when we leave the folder
if [ -f ./Rakefile ]; then
complete -W "SAME AS YOURS above" rake
else
complete -r rake
fi
if [ -f ./Capfile ]; then
complete -W "$(cap -T | grep '#' | awk 'NR != 1 {print $2}')" cap
else
complete -r cap
fi
stripe ;
}

Enhance to the above

Guest — Sat, 22 Mar 2008 11:30:21 -0500

Hi,

Adding the following syntax to your bashrc will dynamically add and remove the completions as appropriate.

cd () {
command cd "$@";
# Add enhanced completion for a folder containing a rails app and remove it when we leave the folder
if [ -f ./Rakefile ]; then
complete -W "$(rake -T | awk 'NR = 1 {print $2}')" cap
else
complete -r cap
fi
}

Hope this helps you out.

Hello Matt. I have to admit

Hello Matt. I have to admit I'm lazy, and just use Ubuntu, which has built-in scripts for this stuff. If there's anything you want me to send (e.g. scripts from particular locations), I'd be happy to send you copies for reference.

Suspend to RAM

Matt — Sun, 16 Dec 2007 21:19:07 -0600

Thanks for the helpful entry. I've been running Debian Sid on the 820 for almost a year now and just finally got around to tackling the suspend to ram problem. Following your tips, I've had a good deal of success, but it doesn't always work. About half the time when I come back from suspend I just get a mouse cursor on a black screen, the mouse moves fine so X is loaded to some degree, but my desktop never comes back. My comment turns into a question at this point, has this ever happened to you?

Also, how are you invoking the suspend? I just echo "3" > /proc/acpi/sleep and i'm wondering if that's part of the problem.

Thanks again for taking the time to post about your experiences and your solutions, it really does make the web a better place.

Specifying "From" address in Postfix

CalJedi — Sat, 15 Dec 2007 21:48:28 -0600

Hi Elliot,
I'm having an issue on my server, which is running Postfix. The issue is that, even when my php script explicitly specifies a "From" address in the mail() function, when i tail the /var/spool/maillog file, I see that the email is being sent as "nobody@servername.com" (where "servername" is the hostname of the box)

Is there anything i can do to force Postfix to use the "From" address that's specified in the script, instead of defaulting to "nobody" ?

Thanks in advance.
