Traveling Tech Guy's questions

We're using NGINX as our main web server, after moving away from Apache. We recently decided to test ClamAV integration, to make sure files uploaded by users are thoroughly scanned prior to transfer to Amazon S3.

I'm looking for an easy way to integrate NGINX and ClamAV, i.e. every file uploaded to a temporary folder gets scanned, and removed if found to be infected.

I found mod_clamav for Apache, but no similar support for NGINX. Is there a good way to integrate ClamAV and NGINX, or should it be done on an application level (i.e., download the file, and then trigger an application that will scan prior to uploading)?

I have an Amazon EC2 dedicated instance (Fedora Linux). Although I took an instance in US West, it came set to EST.
I changed the timezone to PST (export TZ=America/Los_Angeles) and it works - for several hours. Then it resets itself to EST.

What am I doing wrong and how can I set it to PST permanently?

I'm trying to have MySQL point to a directory on an EBS volume I mounted on my EC2 machine.
I took th following steps:

1. Stopped MySQL (/etc/init.d/mysqld stop) - successful
2. Created a MySQL directory on my volume, mounted on /vol (mkdir /vol/mysql)
3. Copied the contents of /var/lib/mysql to /vol/mysql (cp -R /var/lib/mysql /vol/mysql)
4. Chanded the owner and group of that directory to match the original (chown -R mysql:mysql /vol/mysql) - after this step, the 2 directories are identical.

5. Edited the /etc/my.cnf file (commented 2 original lines):

   [mysqld]
   \#datadir=/var/lib/mysql
   \#socket=/var/lib/mysql/mysql.sock
   datadir=/vol/mysql
   socket=/vol/mysql/mysql.sock
   

6. Started MySQL (/etc/init.d/mysqld start) - FAILED

The error file /var/log/mysqld.log contains the following lines:

100205 20:52:54  mysqld started  
100205 20:52:54  InnoDB: Started; log sequence number 0 43665  
100205 20:52:54 [Note] /usr/libexec/mysqld: ready for connections.  
Version: '5.0.45'  socket: '/vol/mysql/mysql.sock'  port: 3306  Source distribution  

No other errors are available.

1. What am I doing wrong?
2. Where can I find the error/s encountered by MySql?
3. If I restore the original lines, MySQL starts, leading me to believe it may be a permissions issue - but permissions are the same for both directories?

Thanks!

I have an IIS6 machine, running multiple web applications. Once in a while, IIS recycles W3WP. When i look at the error codes, W3WP.exe usually exits with return code -2 (0xfffffffe) but one in a while it exits with -3 (0xfffffffd). While the end result is the same, i was wondering if there's any difference/reason to these particular return codes?

[I'm replicating a question I put on Stack Overflow a while ago and received no answer - figuring that it's more up Server Fault's alley (SF didn't exist yet when I first posted this)]

IIS 7 has a very useful feature called Failed Request Tracing (FREB for short). It has a very nice visualization feature, involving an extremely complex XSL stylsheet that parses the results into a useful treeview.

I, however, want to consume FREB programatically, and be able to present the results on my smart client (without waiting for the XML to be written server-side).

The only possible solution I found so far, involves compiling an IIS7 C++ plugin that converts FREB into OutputDebugStrings, an approach even the writer suggets should not be used on a production server (here's the article)

My question is: is there another approach?

As always, my thanks for reading, and even more for replying. Guy
