::A Geek in Korea::

As mentioned previously, KT Telecom sucks at Linux support. My previous efforts at trying to get a new IP address had failed, and I had tried to call tech support to get them to help me with the problem. They advised me to “Install Windows” and “Call back”. Seriously. That was their solution. No thanks.

I’m finally 100% Windows free at home, so I went about finding my own way to fix the problem. This tread at the Ubuntu Forums provided many possible solutions. So, all I had to do was play around with a few commands in the console and eventually I’d get a new IP address? I started to play around.

Linux Geekery Follows
I had tried the solutions listed in the before with no success. I had done

ifdown eth0 && ifup eth0

in a previous attempt. There wasn’t any luck before. I found that

sudo dhclient -r

would “release” my IP address. The problem was that if I didn’t wait for someone else to take that IP address, it was given right back to me. What I ended up doing was disabling the network connection settings in my system tray. I released my IP address with

sudo dhclient -r

then went off the Internet completely by disabling my connection to the network.

Just to be sure, I went to /var/lib/dhcp3 and deleted all my leases for my broadband connection.

Then I went to work. The idea was that I was giving up my IP address and waiting for a new person to come onto the network. When they requested an IP address, they’d take mine, and I’d get a new one when I logged on later.

I had tried this before, but hadn’t waited long enough. My hope was someone would get my old IP, and I’d get an IP that hasn’t been put on a blocklist requiring me to go to a PC-room to post on my own blog.

Several hours later I returned home, turned on my computer, and found I had a brand new IP address. Awesome. Now I can post and not get false positive blocked by SPAM filters in Wordpress. Who needs Korean Tech support? Not me…this time, at least.
