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.

TBH, had you used iptables-save, you'd save yourself a huge amount of time...

comment Weird socket behavior in VirtualBox (NAT + PAT)?
I assume the lines with nc -v mydomain.com is executed from another host. If so, try doing that again, then on the VirtualBox host, enter the command netstat -tp | grep 2001 to see what process is bound to port 2001.

comment Cannot mount external FreeNAS NFS on XenServer VM or Dom0
IIRC, nfs has its own (simplistic) IP filter, so only allowed servers can connect to an exported share. Have you ensured that the IP of your VM is allowed access to the exported nfs share?

Not sure what your needs are, but if IOPS is a top priority for you, check out Fusion-IO's ioDrive products.

comment Synchronizing RODCs to NTP servers?
@MDMarra perhaps you're right. But anyways, the author also doesn't see any problems having more than one Reliable Time Sources, as long as they are synced to time sources that differ no more than 5 minutes.

comment Synchronizing RODCs to NTP servers?
@MDMarra it is implied in the paragraph beginning with "Yes you should.", and also implied by his answers on the question regarding DCs syncing to different time sources. He did not explicitly recommend the practice, it's just my interpretation. He did, though refer to other authors actually recommending such practice.

comment zfs - two pools with nested mountpoints and conflicting mount order
Alternatively, do a bindmount instead of symlink; some software want some directories to be honest-to-goodness actual directories instead of symlinks.

comment Synchronizing RODCs to NTP servers?
Hmm... after mulling about your answer, I think I'll just let the RODCs to sync with the DCs at Head Office... just in case the time source at the branch offices go haywire. Because the branch offices have no Internet connection on their own; all traffic must go through the Head Office. Thanks! Marking yours as the answer.

comment Active Directory inter-domain trust questions to thwart malicious programs
@joeqwerty The tracking is done by slowly going over the Event Log until we can narrow down the culprit(s). The new domain is just to protect some accounts from being locked out.

Hmm... that's an interesting solution... although it doesn't directly answer my questions, I'm going to sleep on it. Thanks for the suggestion!
