Couple days ago installed Collabtive to manage my small projects in one place.
It is a PHP based solution with nice user interface that ideally fits my needs as it offers:
The fastest way to download or upload directory tree over FTP using just plain console is to execute
lftp is a sophisticated file transfer program which supports protocols like ftp/s, http/s, hftp, fish, sftp and torrent. It is a good idea to install this tool as it can be very handy at times.
To upload local directory local_dir to remote remote_dir on hostname execute:
$ lftp -u username,password -e "mirror -R local_dir /remote_dir;quit" ftp://hostname Total: 1 directory, 3 files, 0 symlinks New: 3 files, 0 symlinks 20071573 bytes transferred in 162 seconds (121.8K/s)
To see contents of remote directory remote_dir on hostname execute:
$ lftp -u username,password -e "ls /remote_dir;quit" ftp://hostname total 19612 -rw-r--r-- 1 nobody nogroup 15568717 Feb 25 23:29 eGroupware.zip -rw-r--r-- 1 nobody nogroup 113942 Feb 25 23:29 eGroupware-egw-pear.zip -rw-r--r-- 1 nobody nogroup 4388914 Feb 25 23:30 wordpress.zip
To download remote directory remote_dir on hostname to local local_dir execute:
$ lftp -u username,password -e "mirror /remote_dir local_dir;quit" ftp://hostname Total: 1 directory, 3 files, 0 symlinks New: 3 files, 0 symlinks 20071573 bytes transferred in 20 seconds (981.0K/s)
Don’t forget to read manual as there are couple of useful options (like downloading/uploading files in parallel).
I recently read an article about Booktype, got interested and tried software myself.
Booktype is developed by Sourcefabric, a non profit organization that provides couple of other interesting solutions like Airtime (radio automation), Newscoop (content management system) and Superdesk which combines Airtime with Newscoop as a suite for independent media.
Booktype uses Django web framework. Software is easy to install but you can’t forget about
Interface is simple and readable built with collaboration in mind. Each book has its own history, custom versions and permissions. Books are written in HTML using TinyMCE editor and can be exported to PDF, ODT, EPUB and MOBI format.
To integrate Roundcube with ISPConfig 3 read requirements and follow installation instructions.
Procedure is quick and simple as it contains following steps:

Recently I run into small problems related to PHP.
Problem A – sqlite.so
First one was PHP warning:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/sqlite.so' - /usr/lib/php5/20090626/sqlite.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP tried to load sqlite.so from /etc/php5/conf.d/sqlite.ini (php5-sqlite package).
$ dpkg -L php5-sqlite /. /etc /etc/php5 /etc/php5/conf.d /etc/php5/conf.d/sqlite3.ini /etc/php5/conf.d/pdo_sqlite.ini /etc/php5/conf.d/sqlite.ini /usr /usr/share /usr/share/doc /usr/lib /usr/lib/php5 /usr/lib/php5/20090626 /usr/lib/php5/20090626/pdo_sqlite.so /usr/lib/php5/20090626/sqlite3.so /usr/share/doc/php5-sqlite
As suspected there was sqlite3.so file.
$ ls /usr/lib/php5/20090626/ curl.so gd.so mysqli.so mysql.so pdo_mysql.so pdo.so pdo_sqlite.so sqlite3.so
To solve this problem just delete /etc/php5/conf.d/sqlite.ini file.
$ sudo rm /etc/php5/conf.d/sqlite.ini
Problem B – fuser process
Second problem was more serious. Thousands of fuser zombie processes and funny CPU usage.
Hopefully there is a bug report #876387 so for solution look at fourth comment. Don’t forget to identify and kill already running find processes.
In short this problem can be quickly recognized by thousands of fuser zombie processes:
$ ps ax | awk '{if ($3=="Z" && $5~/fuser/) s++}; END {print s}'
21613It was created by php cron job /etc/cron.d/php5 (php5-common package):
$ dpkg -S /etc/cron.d/php5 php5-common: /etc/cron.d/php5
Source of this problem in /etc/cron.d/php5 file:
09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {} 2>/dev/null \; -deleteTo solve it replace this line with one given below:
09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) -delete
Don’t forget to kill running find processes:
# ps ax | grep "find /var/lib/php" | grep fuser | awk '{print $1}' | xargs killDownload mb2md.pl script and run as described in manual.
For example to convert /old/mbox to /new/maildir you can execute:
# perl ./mb2md.pl -s /old/mbox -d /new/maildir Converting /old/mbox to maildir: /new/maildir Source Mbox is /old/mbox Target Maildir is /new/maildir Dummy mail system first message detected and not saved. 40 messages.
