Why is my laptop so freaking hot?
Posted by evan in Uncategorized on August 26, 2010
HP Compaq nc8430, Core 2 Duo T7200 2.0GHz. Fedora Core 12 x86_64, kernel 2.6.32.19-163.fc12.x86_64 (just updated via yum).
At idle, with nothing running in the foreground, the CPU is around 70-72° Celsius, and the other sensors are 80°+. Why is this? It seems like every time I run yum update the machine gets hotter. I wonder if there’s any way to figure out what’s causing this. In any case, it’s pretty annoying. It’s uncomfortable putting the thing on my lap for any length of time.
Notice the temperatures at the top. The first two are Core0 and Core1, the other 2 are other sensors. The CPU is running at 1.0 GHz due to SpeedStep and the temp is still 70°C.
Edit: I forgot I’ve been logging temperature via sensord. I just turned the computer on after having it off all night and within 10 minutes the CPU is back up to > 60°C.

Blocking comment spammers by IP
Posted by evan in Uncategorized on August 13, 2010
I use Akismet to block comment spam, but it still annoys me that it even exists. Last night I put a simple IP ban into my httpd config. But who to block?
I used a grep & Perl to get a rough guess of which IPs were submitting the most comments (working on the assumption that one IP address submits many spam comments) It took me about 20 minutes to write this mess but it does what I wanted to do:
[root@lunix ~]# zgrep POST /var/log/httpd/evanhoffman-access_log-201008??.gz | grep comment | perl -ne 'chomp; $_ =~ m/(?:\d{1,3}\.){3}\d{1,3}/; print "$&\n";' | perl -e '%a = (); while (<>) { chomp; $a{$_} += 1; } while (my ($key, $value) = each (%a)) { if ($value > 1) { print "$value\t=>\t$key\n";}}'
2 => 218.6.9.140
180 => 91.201.66.34
2 => 213.5.67.41
2 => 188.187.102.74
[root@lunix ~]#
That’s pretty hard to read. Here’s a quick explanation of each piece:
zgrep POST /var/log/httpd/evanhoffman-access_log-201008??.gz
Use zgrep to search for the string “POST” in all of the gzipped Apache logs for August. Pipe the results (the matching lines) to the next part:
grep comment
grep for the string “comment”. This isn’t really scientific, but I feel safe in assuming that if “POST” and “comment” both appear in the HTTP request, it’s probably someone posting a comment. Pipe the matches to…
perl -ne ‘chomp; $_ =~ m/(?:\d{1,3}\.){3}\d{1,3}/; print “$&\n”;’
This is a perl one-liner that uses a regular expression to match an IP address in a given line and print it out. The original regex I used was \d+\.\d+\.\d+\.\d+, this one was slightly fancier but did the same work in this case. It’s worth noting that this will only print out the first match in the given line, but since the requester’s IP (REMOTE_ADDR) is the first field in Combined Log Format, that’s fine this case.
The output (the IPs from which comment posts have been made) is piped to…
perl -e ‘%a = (); while (<>) { chomp; $a{$_} += 1; } while (my ($key, $value) = each (%a)) { if ($value > 1) { print “$value\t=>\t$key\n”;}}’
This is another perl one-liner. Basically, it maintains a hash of String=>count pairs, so each time it sees a string it increments a “counter” for that line. Then when it’s done receiving input (i.e. all the data has been processed) it prints out the contents of the hash for keys that have a value > 1 (i.e. IPs that have POSTed more than 1 comment).
The output shows pretty clearly where the spam is coming from:
2 => 218.6.9.140
180 => 91.201.66.34
2 => 213.5.67.41
2 => 188.187.102.74
180 submits from 91.201.66.34. Out of curiosity I looked up that IP in whois:

Not much info other than the IP is based in Russia. Well, anyway, I IP blocked 91.0.0.0/8 (sorry, Russia), so if you’re in that subnet you’re probably seeing a 403 now.
Edit: It occurred to me that I can accomplish the same thing while being less draconian if I wrap the Deny in a <Limit></Limit> clause. This way everyone can still see the site but certain IP ranges won’t be able to POST anything:
<Limit POST PUT DELETE> Order Allow,Deny Allow from all Deny from 218.6.9. Deny from 173.203.101. Deny from 122.162.28. Deny from 91. Deny from 213.5 </Limit>
Amazon EC2 – ext3 mkfs takes 30+ minutes?
Posted by evan in Uncategorized on August 2, 2010
I’ve been playing around with Amazon EC2 for a new project I’m working on and so far I’m really impressed. One thing I’ve noticed, however, is that it takes forever to create an ext3 filesystem on a new volume. For example, the below command took over 30 minutes to create the filesystem on a 300 GB volume:
# mke2fs -j -m0 /dev/sdf1
mke2fs 1.40.4 (31-Dec-2007)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
39321600 inodes, 78642183 blocks
0 blocks (0.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
2400 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000, 7962624, 11239424, 20480000, 23887872, 71663616Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: doneThis filesystem will be automatically checked every 38 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
It took about 30 seconds do do everything up to the writing of the superblocks. Not sure why this takes so long, but it’s happened for every EBS volume I’ve formatted ext3. Annoying. Initially I thought it was hanging, and ended up terminating an instance that wouldn’t shutdown or let me cancel the operation. The terminated instance is still being displayed in the UI with a status of “terminated” and I can’t find any way to remove it from the list.
Finally got this DVD ripped and copied to my iPhone

This was a lot more work than I expected. Then again, I am a newb. And lazy.

Ripping a DVD on Fedora Core 13
Posted by evan in Uncategorized on July 2, 2010
I thought this would be a pretty straightforward task. It was, though it took several minutes to track down the CSS library needed for decryption of the DVD. All I want to do is copy Talking Words Factory to my phone so my kid can watch it in the car if needed. It looked like Brasero was the tool for the job, but I got some error about needing a plugin for it to be able to decrypt it. I found libdvdcss here and after installing the RPM, everything worked. Now I just need to encode it with ffmpeg.
Flash plugin on Firefox on Fedora 12 x86_64
Posted by evan in Uncategorized on June 9, 2010
I know I’ve been through this before because I’ve setup Fedora before and it’s working. But I just installed FC12 on my desktop at home (since my Seagate drive bricked itself a few days ago and I had to reinstall anyway) and while I finally got the Adobe Flash plugin working, it didn’t have any audio, which made YouTube kind of suck. Anyway, this of course was a solved problem, I just forgot where the fix was located… but duh, it’s on the Fedora website. A simple
yum install flash-plugin nspluginwrapper.x86_64 \
nspluginwrapper.i686 alsa-plugins-pulseaudio.i686 \
libcurl.i686'
and everything appears to be fine. Thank you Fedora!
libiphone / libmobiledevice is now in the official Fedora repo!

Hooray! This was strange though:
Windows XP guests hang on shutdown in VMware Workstation on Linux
Posted by evan in Uncategorized on April 23, 2010
I had this problem with FC11, where I couldn’t properly shut down or suspend the Windows XP VM I run (mostly for Outlook). When I’d shutdown inside the guest, it would mostly do what you’d expect, but then the screen would go blue, then black, and then the only way I could get the thing to exit was to kill the pid of vmware-vmx (or a ‘killall vmware-vmx’). I solved it somehow by removing some RPM, but when I went to FC12 the other day it came back, and I couldn’t remember how I’d fixed it initially. I Googled for nearly a full day before I found the original blog post that told me which RPMs to remove – for some reason I thought it was fprintd, but it was something else completely. Here’s the original post, and when I just read it I was going to comment on it to say thanks for posting it, but apparently I did that already. Anyway, I removed pcsc-lite again and everything appears to be good now.
Upgraded to Fedora Core 12
Posted by evan in Uncategorized on April 20, 2010
I upgraded my work laptop from FC11 to FC12 yesterday using the “preupgrade” tool. It was pretty simple, though it took a lot longer than I expected. There was some funkiness with my screen going crazy after the upgrade – my external monitor and the laptop’s LCD both did this crazy wavy-line thing. I tried changing the refresh rate, running system-config-display, nothing worked. I found a post that suggested passing “nomodeset” to the kernel boot options – that solved it. Yay!
The other problem I had was reinstalling VMware Workstation – I couldn’t. I got this error: /tmp/vmware-root/modules/vmnet-only/vnetUserListener.c:240: error: ‘TASK_INTERRUPTIBLE’ … etc. I ended up having to edit the vmplayer source files directly (!!!) to get them to compile – instructions found here
So far FC12 seems exactly like FC11. But that’s fine – I only upgraded because I didn’t want to be on a dead-end version once FC13 is released.
