Setting up webcam on Linux (ZC0301)


It was a rare occasion if I got my hand on a web camera. This time I borrowed it from my colleague. Last time I couldn't get it to work. I didn't remember why. But this time, it was easy as ABC.

Spec:
Model : Z-Star Microelectronics Corp. Havit 3808 (this is what it says on the tin)
Chipset : ZC0301 (from lsusb)

Last time I looked at http://zc0302.sourceforge.net/ for the driver. It has been inactive for a long time. Still so far, the driver for ZC0301 is still not supported.

This time: I looked at spcaxx project page at http://mxhaard.free.fr/spca5xx.html. The webcam I was using supported. As stated on the website, for Fedora Core 6 users like me can download the driver here. The driver is actually a kernel module and after installing it, you can load the module with modprobe : modprobe gspca

When done, open your kopete, and click Settings --> Configure.. --> Device and see whether it detects and display video from the webcam. Then you can enjoy webcam session with your friends and acquaintances.

Good luck!

mplayer-gui error : Error in skin config file

After installing mplayer-gui package, I can't start it.

$ gmplayer MPlayer 1.1-4.8 (C) 2000-2012 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support. You will not be able to use your remote control. Error in skin config file on line 6: PNG read error in /usr/share/mplayer/skins/default/main Config file processing error with skin 'default'
After googling a bit, I found out that it was due to the png files in dir /usr/share/mplayer/skins/default. This is the default skin directory. To fix this error, I have to install ImageMagick package because I want to use the convert program to convert all of the png files to format png24. Thus, cd /usr/share/mplayer/skins/default; for FILE in *.png ; do sudo convert $FILE -define png:format=png24 $FILE ; done
Rerun gmplayer and all should be fine.
Have fun!

It doesn't work on Ubuntu 16.04 (xenial) but there's a workaround here.

Transparent proxy with squid 2.6

I have upgraded my squid from 2.5 STABLE13 to 2.6 STABLE18. Transparent proxy is setup differently in this version. You need this directives in squid.conf (usually in /etc or /usr/local/etc or /usr/local/squid/etc, check with your distro).

acl our_networks src 192.168.2.0/24 127.0.0.1
http_access allow our_networks
http_port 192.168.2.1:3128 transparent
always_direct allow all

where 192.168.2.1 is your proxy server IP address.


If you have flushed your iptables, create new rule:

iptables -t nat -A PREROUTING -i eth0 -p tcp –dport 80 -j REDIRECT –to-port 3128

where 3128 is the port where squid is running.

postfix - mailbox size limit and message size limit

postfix is my MTA of choice. I use it for my mailserver because its simplicity , security and sendmail-compatible (the widely used smtp in the world but not as secure). It is also extensible by plugging other servers for various purposes (antispam, antivirus,database etc).

I had one problem with file attachment larger than 10MB. Users couldn't send it although I have setup squirrelmail (SM) to be able to attach files summed up more than 20MB and I had modified php settings as per here. The problem was not in SM setting. It was postfix. By default, attachment size that can be sent by postfix is 10MB ~ 10240000 byte. How did I know it? I looked in log file (for my system it is in /var/log/mail/errors. For other system, the file to look is /var/log/maillog). The line looked like this:

Feb 26 16:30:53 webmail postfix/sendmail[30775]: fatal: me@mymailserver.org(74): Message file too big


Solution
Open /etc/postfix/main.cf with a text editor of choice and find message_size_limit directive an…
