I'm running a CentOS server which I had to reboot.
However, after the reboot I found myself unable to install wordpress plugins via its admin control panel, as I'm getting a 'failed to connect' message:

This is strange since the the same configuration worked before the reboot.
Any ideas on what can be the problem?
iptables -L -v -n,chkconfig --listandnetstat -an? Make sure you do this with the appropriate rights (sudo/su) – Bart De Vos Oct 11 '11 at 9:38chkconfig --listlook for a line with FTP. Innetstatlook for lines containing ftp, 20 or 21. – Bart De Vos Oct 11 '11 at 10:01ps -ef | grep ftp? – quanta Oct 11 '11 at 10:08chkconfig --listoutput that has ftp in it is this:vsftpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off.netstat's output doesn't give me anything containingftp, 20 or 21 – Lea Cohen Oct 11 '11 at 10:34
