Squid - File size limit exceeded

Yesterday (15th Feb 2008) my squid died unexpectedly. I tried to restart it several times but to no avail. So I tried to see what went wrong by debugging and ran it in foreground. So,

squid -NCd3

N = put it in foreground
C = don't catch fatal signals
d = set debug level (3 is the level)

It threw a bunch of messages with the last line was File size limit exceeded. Just like this but I got no core dumped!. With no clue how to solve it, I recompiled squid (2.6-stable17) with extra parameters (with-max-fd=8192 and --with-large-files):

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-icmp --enable-kill-parent-hack --enable-ssl --enable-linux-netfilter --enable-large-cache-files --enable-follow-x-forwarded-for --with-large-files

It solved it. Shane reported here that this happens when file store.log is bigger that 2 GB. Disabling the use of store.log (or other relevant files for that matter) will get rid of this problem.

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…
