comment Best method to protect software PBX system from disaster
Should I expect any difficulties with re-activating Windows Server 2003 on different hardware?

comment Best method to protect software PBX system from disaster
I've considered trying to replicate the system in a virtual machine, but I don't think it's a viable option since the software needs access to the T1 and POTS cards for controlling the PBX. I'll look at SSR, my experience has been with Norton Ghost which hasn't worked in the past.

comment zsh autocompletes folders that don't exist
never used zsh, but I know bash supports completing hostnames from /etc/hosts in addition to folders that exists. Is there a proxy in your hosts file?

comment Multiple Enterprise-level Western Digital hard drives failing
I considered that, but I don't think there's an unusual level of vibrations in the environment. The server has spent most of it's life with only a layer of carpet between it and cement. The last six month, though, it's been on a shelf sitting on a wooden floor raise above the ground. The one noisy failed drive was vibrating just a bit, but a good RE3 drive was sitting in-between the two recently failed drives.

comment Can't access a user profile as administrator?
@Sonny I tend to be very persistent about this as well though I don't always get to the bottom. Next thing to test is filesystem corruption. Have you tried running scan disk?

Well, I'd be downloading an Ubuntu/Knoppix LiveCD at this point. Works great at getting around those pesky permissions.

Did you verify Administrator is in the local Administrators group? And take a look at the above article I mentioned?

comment How secure is Remote Desktop Connection?
@Shane WEP was also a bad implementation of RC4, it not entirely RC4's fault when one used only a 40-bit key and 24-bit seed. But, RC4 is getting a little old now.

This specific feature is only available on Server 2003 x64, Vista, and newer. Also, I believe the XP RDC client lacks the ability to verify even if connecting to newer computers so every connection can be at risk.

comment how to copy & gzip files individually over ssh
And quote any variables, of course: find -type f | while read -r fname ; do cat "$fname" | gzip -c | ssh remote "cat > '$fname.gz'" ; done or using dd: find -type f | while read -r fname ; do cat "$fname" | gzip -c | ssh remote dd of="'$fname.gz'"; done When using ssh, it requires two levels of quotes since both the local shell and remote shell have a chance to expand variables. Note: this will break on filenames with single quotes. If you replace the single quotes in the ssh command with \" then it will instead break on filenames with $, ", or ` (back-tick)

comment how to copy & gzip files individually over ssh
As an alternative to file redirection, there's always dd. It tends to require less ugly quoting. cat dafile | gzip -c9 | ssh remote dd of=dafile.gz Also, for a slightly safer read, add -r, it stops read from interpreting any backslashes in the filename should you decide to use them.

comment Noob confused with DNS and WHM /cPanel install
Yes. If you plan to move to a different IP later, you can lower the TTL, say, an hour or more before the move to improve the speed of clients seeing the new A-record once you update it.

comment Using ssh-agent with KDE?
I started doing this once I realized it's not really less secure than running a per-session agent if I never really log out. The recommended way to use ssh-agent is not in Autostart, but use it kinda like sudo to run startkde. For example, "ssh-agent startkde" Before startkde runs, SSH_AUTH_SOCK is setup and when startkde exits, so does ssh-agent. It's more reliable than depending on Autostart, but trickier to set up correctly. Ubuntu has support to make this easy to do and will even generate a chain of commands like this. Looking at ps, I see "ssh-agent gpg-agent dbus-launch gnome-session"

comment apply back firewall after iptables flush
Oops, I completely ignored the tags. I'ved used older Fedora, but never CentOS, but guessing on what I remember, you should have an init script for the firewall at either /etc/init.d/iptables or /etc/rc.d/init.d/iptables. You might have a file that stores the iptables configuration at /etc/sysconfig/iptables. The contains will be RAW arguments to iptables to initialize it. You should also have a local start-up script that runs last on boot at either /etc/rc.local, /etc/rc.d/rc.local, /etc/init.d/local, etc. In that file you can add the above iptables command as a safety net and reboot.

comment Centos running Hudson freezes, what logs to check to find out why?
Analyzing a previous crash? Mostly, logs like /var/log/messages, /var/log/syslog, and /var/log/debug. 99% of logging goes there. If your kernel is panicing, it can be configured to do a dump you your primary swap partition and then saved to /var/log/dump on reboot. You can also enable automatic reboot on panic rather than halting with the sysctl kernel.panic. Add kernel.panic = 30 to /etc/sysctl.conf and run sysctl -p.

comment apply back firewall after iptables flush
Without knowing your Linux distribution, I can't help you with specifics on your firewall, but you could add "iptables -A INPUT -p tcp --dport 22 -j ACCEPT" to some start-up script, like /etc/rc.local that runs at the end of boot. Once you reboot, you can test everything and also see if removing that rule locks you out. Run "sudo shutdown -r +5" and then put the command in the background with Ctrl-Z followed by bg. Lastly, remove the above rule with "iptables -D INPUT -p tcp --dport 22 -j ACCEPT" If you get locked out, your server will reboot in 5 minutes and re-add the rule from rc.local.

comment apply back firewall after iptables flush
Yes and no. Yes, simply rebooting should restore your firewall state to normal if all you did was play with the iptables command which does not save anything to a file. No, -F does not restore your firewall to it's normal boot-up state. It flushes any rules in the current table, but does not load any rules that might have been loaded during boot.

comment Non technical explanation for Reverse Proxy
Ok, a normal, regular, plain-old proxy is run on the side of the Internet where users are browsing the web. A reverse proxy is run on the opposite side the web servers sit hosting your favorite web sites. That's as non-technical as I can get.

comment how to move an SSL certificate from one windows server to another
It should say at the bottom of the certificate information. Take a look at this for an example: jacco2.dds.nl/networking/screenshots/cert/certinfo.png
