Beginning today, I started to receive the following when ftp’ing to my CentOS 6 machine:
ncftp /home/pyz2 > dir connect failed: No route to host. connect failed: No route to host. connect failed: No route to host. Falling back to PORT instead of PASV mode.
I can make a connection, but I can’t get a directory listing or transfer data/files.
What I had been doing is adding more directives to my /etc/hosts.deny file, today to include certain categories of ip addresses for the vsftpd service.
I unwound that after I saw the problem starting to occur, and have restarted vsftpd several times.
That hasn’t changed the above issue.
And yes, I’ve googled.
My firewall setting has port 21 open.
I can remotely telnet to hostname 21
and I get a response indicating that the port is open.
Any advice would be appreciated.
