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! UPDATE (02-10-2017)
It doesn't work on Ubuntu 16.04 (xenial) but there's a workaround here.
Recently, my server's only hard disk was almost full. I bought a new hard disk with bigger size and I decided to just add it as a second hard disk. Since I need to move it to the 2nd hard disk, I need to find a proper way to move the db with minimum downtime. So I googled around and found a solution. First, I needed to format the 2nd hard disk and I chose xfs as the filesystem. I created 2 partitions using Linux's fdisk for this task. First partition is 10 GB and 2nd one is around 900 GB. That's approximately added up to 1 TB. Then I mounted the 2nd partition in current partition eg /media/hd2 as follows: mount -t xfs /dev/sdb5 /media/hd2 where /dev/sdb5 is the partition and /media/hd2 is the mounting dir. Stop mysql db before doing anything: service mysql stop Afterthat, I copied the entire db to newly mounted hard disk: cp -rv /var/lib/mysql /media/hd2 It will take a while if you have huge databases. Then, change the ownership of the dir to user and group of mysql: chown -R mysql:…
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:
