Windows Azure Ubuntu - 500 OOPS: priv_sock_get_cmd error while making an FTP connection [closed]

Question

I have created a VM on Windows Azure and running Ubuntu on that I have been able to successfully communicate using the http protocol on port 80

However, I am not able to make a successful FTP connection. Here is what I have done so far

• Created an End Point with both public and private port as 21
• Installed vsftp on the server
• Made the config changes in vsftpd.conf; local_enable=YES, write_enable=YES

Now when I try to make a normal FTP connection on Filezilla, I have and error which says500 OOPS: priv_sock_get_cmd

Can someone please let me know what I am missing

Help would be greatly appreciated Thanks

Answer 1

The following may help:

seccomp_sandbox=NO

Answer 2

As reto suggested, adding:

seccomp_sandbox=NO

To your vsftpd.conf file (usually located in /etc) should fix this problem (make sure you "sudo service vsftpd restart" afterwards).

VSFTPD uses kernel module seccomp in a way that produces this bug on certain kernels. See this post for more info: http://chemdroid.net/en/ubuntu/23-vsftpd-500-oops-priv-sock-get-cmd.

I wanted to add this detail to reto's post, but I don't have enough reputation to comment yet...
