Die Axt im Hause ersetz den Zimmermann!
In diesem Fall sprechen wir von ImageMagick. Unter Debian installiert man es ganz einfach mit
apt-get install imagemagick
die folgende Zeile erledigt dann die Konvertierung des PDFs in das JPG
convert -density 300 file.pdf file.jpg

Für den Parameter -density sind übliche Werte wie 72, 300, 600 ohne Problem verdaulich.

Problems with vsftp and debian

Posted by admin on Sep 4, 2009 in Allgemein, Work Related


´After spending the whole day tweaking and experimenting with vsftpd I
now have it setup as follows. Anonymous login, read only, with upload
enabled in one directory. I have a list of local users that can login
over SSL, and have read/write access to files in their jails. The
problem is that some of these users I want to be ftp-specific so they
don’t need valid shells. However if any of the users has the
shell /bin/false in the passwd file then when they try to login to the
ftp is says LOGIN INVALID. Please, how can I go about allowing users to
loging but without giving them valid shells?

A lot of experimenting revelaed vsftpd would only let users login that
had a home directory of /home/$user and a shell, either /bin/bash
or /bin/sh specified in /etc/passwd. I’m stumped.

Sorry, I should have covered that. You can add /bin/false instead
of /sbin/nologin to the list of shells in /etc/shells. We use
/sbin/nologin for compatibility across our various Redhat, Fedora,
Debian and Ubuntu systems.

Make sure you have
