I recently upgrade my Ubuntu server to 13.10. Mostly works fine except VSFTPD stops working. Everytime I tried to login via command line ftp client I got the following error:
After some googling I found out the problem: the new kernel module “seccomp”, which is used by VSFTPD since 3.0.0, is used on x86_64 kernal with Ubuntu 12.04+. 3.0.0 is quite unstable when working with seccomp (for more info about seccomp, please see wiki page). To fix the problem, simply add the following line to the /etc/vsftpd.conf file on your server:
And then restart the vsftpd server:
sudo service vsftpd restart
Try to login again and this this it should work like a charm..
