I call myself an IT Optimizer, always looking for ways to optimally use whatever IT Infrastructure I have available.

Currently, I work as the IT Infrastructure Manager of Sophie Paris; I manage a department that's responsible for all production-level infra, including networks, storage, and servers.

Previously, I've worked as:

  • System Administrators Manager of PT Carrefour Indonesia, Indonesia's largest hyper-retailer. Here I oversaw the management of Windows- and Linux-based infrastructure throughout the country.

  • IT Manager of Infrastructure at PT Panin Sekuritas Tbk, one of Indonesia's leading securities companies. Here I design, deploy, and maintain 'next-generation IT Infrastructure' (secure, highly-available, and performant).

  • Senior instructor for the CCNA, CCNP, MCSE, and CEH certifications.

If you want to communicate with me, feel free to circle me on Google+. I'm quite active there.

comment Why do servers have SAS instead of SSDs?
I second what Frank said. For instance, HP's 240 GB SSD for ProLiant Gen8 servers are priced around 320 USD. Three times as expensive as the 'non-enterprise' versions. Add about 30 USD and I get a 1 TB spinning-disc SAS HD. More than 4x the capacity at merely 10% price raise.

comment how to rotate nohup.out file without killing my application
That totally depends on whether nohup appends to nohup.out line-by-line, or whether it maintains a pointer to nohup.out's location. See serverfault.com/questions/221337/… for an example.

comment iptables Tips & Tricks
Nice! I'd use ipset rather than elongating the iptables chain, but the idea is great and I think I'll apply them to my production servers. Thanks for sharing!

We all missed 'obvious things' every now and then... shows how important a checklist is :) ... glad you have it solved.

comment IPTables custom log failing
Glad it worked. I decided to not give up because (1) I once had the same problem, and (2) I solved it. But I did not remember exactly how I solved it, hence the several failed attempts in the Q's comments :)

comment IPTables custom log failing
I feel your pain... last ditch suggestion: Try :rawmsg,contains instead of :msg,contains ... if this doesn't work, I give up.

Or try startswith instead of contains

Hmmm... if you cut the match string to "[10010]", does it work?

Try renaming iptables.conf to 11-iptables.conf, and restart syslog. There might be other rsyslog filtering rules that got triggered before the :msg,contains rule you're using. Prepending 11- should help your rule to start quite early.

Make sure that the network interfaces' names are exactly the same on both hosts, with exact same settings.
