Comment on gdb: ptrace: Operation not permitted by Andy Hill

Mad props! I was ready to beat my system to a pulp because I couldn’t get a gcore or gdb memory dump, even as root. Of course I was running strace on the process

Comment on Lenovo T430 running Kubuntu 12.10 for extreme battery life. by Robert

the laptop-mode-tools configuration I use auto-sets the powertop tuneables when the charger is unplugged. yes, I agree completely about the need to use them. I’m idling around 11W, but I leave the bluetooth radio on for my mouse and audio and run a Win7 VMware Workstation guest almost constantly. Last week I hit 6 hours with reported 40% battery life remaining using only the extended 9-cell. I’m using full-disk-encryption as well, but that doesn’t appear to eat battery like I’d expect. I’m curious what you have different to get the extra 3W savings, because my additions can’t account for that much usage.

Thanks for the note!

Nice post. Going to compare few of your files with mine.

BTW, I am currently running kernel 3.4.28 (openSUSE 12.2) on my ThinkPad T430s and my battery consumption is quite good (tip: #powertop tunables=good), idling at around 7-8W with screen @60% and Wireless=On. With Main I get ~4.5 hours and with added UltraBay 3-cell over 7 hours, roughly same as on WinPlatform.

Comment on netlogon error 5602 in Windows 2008 by Joey

You are a life saver. I was doing a new server migration and decided to make things easier by renaming the new DC with the old DC’s name. After troubleshooting that failed attempt for 4 hours I came across your article and it led me in the correct direction. I wasn’t able to do the steps in safe mode as it kept giving me a “network path not found” error. Rebooted in normal mode and it gave me the same error. Modified my DNS server from 127.0.0.1 to the actual server IP on the NIC and it erred once more but didn’t give a description. Rebooted and it came back up normally. I think I’ll leave it alone from here. Thanks again!!!

Thanks for this. I had the same problem. Was trying to attach gdb to apache but kept failing. Read your post, went back and checked and a mate was stracing the same process to file. Killed that. Works now. Thanks!

Comment on How To: Change a Domain Controller IP address: Multi-DCs by Robert

The key is having both IP addresses working on the DC simultaneously long enough for DNS replication of the AD-integrated zones.
I have found that AD works much better if you always have 1 DC available somewhere in the network. If that server has 2 IPs, that’s not terrible, and better than no DCs online. I hope that helps. Did you read the followup article on multi-dc changes?

I know this is an old thread but…what if you are moving BOTH DC’s to a new subnet? Can I change both at the same time or do I need to move one, verify replication, and then move the other?
