I've been in the IT industry since 2000. I have a degree in physics but chose to make my career in IT. Currently I spend more time working with system security than writing code but when I have the time I enjoy perl, php and mysql.

Currently working on:

LAMP servers
Postfix
Windows Server 2008
Network Administration
Security Administration
Asterisk

comment Quotas in vsftpd?
I think I have it correct. The 100Mb file will truncated by 20Mb making it 80Mb.

comment Where to purchase a server capable of 512GB of RAM?
@pfo: 512MB servers? - seems like a far cry from a fair comparison. I bet that is just a typo..

comment postfix/squirrelmail login own domain only
@Tiddo - with all due respect, your question is broad in the sense that it will require configs for postfix, http, iptables, and possibly mysql and will be difficult to answer without significant documentation. Would you mind posing your question in a more detailed manner? That way, you'll receive more than generalized answers (and guesses) in return.

comment Email postfix marked as spam by google
note that BillThor's suggestion of needing a PTR record is really important. You will more than likely need to get your ISP to define this PTR record on your behalf. I've been able to define my own PTR records when I had access to entire class C networks but had to rely on the ISP when I was dealing with smaller network blocks.

looking forward to trying this. As I said, I've used mkinitrd but I did not attempt to install a kernel (kind of assumed I already had one - albeit a "broken" one. What VM environment did you migrate from?

comment Migrate Xen DomU to VMWare ESXi
you mentioned that you've been able to migrate linux DomU without any problems. Man I've spent a lot of time on that and am spinning my wheels. Can you point me in a good direction?? - ps I know this is an old post, hoping you'll notice my comment...

comment puppet variables
@joey - You don't need to update you puppet clients for this to work since it's server side (although updating the clients isn't a bad idea).

comment What is bottleneck of my Apache server?
spend some time here: httpd.apache.org/docs/2.0/misc/perf-tuning.html. This will help you understand how to fashion your question. Note the "Choosing an MPM" section.

comment Failing to connect to server via SSH - “Server refused to allocate pty”
Don't get sidetracked by the pty error, you should verify that your . files in you user's home directory aren't broken. Create another user and compare what the default files are in the new users directory to the files for florian.

@Chris Nava - I totally agree with you on version control. But you're not addressing his question and rather just providing your opinion.

comment deleting linux cached ram
perceived load time over real load time - that's part of what I'm attempting to explore. I have a followup question that is a good cross reference: serverfault.com/questions/108745/…

comment PID ran away with all our MEM and SWAPPED hard - OSSEC RHEL
I'm starting to think that our XEN environment was partly to blame. No real proof yet. I'm just amazed that an editor was able to use 28GB of ram when the save file was 2909 bytes.

the other options show various defaults. I'll spend some time getting adjustments approved
