I was previously backing up all our Mikrotik routers in RANCID but it
was difficult for some techs to work with - the files wouldn't always
paste back in correctly and randomly had capitalization errors, etc,
that would cause issues. So I decided to build an FTP system to back up
the binary configuration files instead.
I have something in the scheduler that backs up the current config to
'today.backup'. I then have a script on a remote server that FTPs in,
pulls the file and exits. It works fine.. other than the fact that ~50%
of the Mikrotiks do not work. What specifically does not work is any
kind of data transfer - I *can* connect and authenticate.
220 BRLLWIKSSW-RTR1 FTP server (MikroTik 4.12) ready
Name (x.x.x.x:simon): admin
331 Password required for admin
Password:
230 User admin logged in
Remote system type is UNIX.
ftp> ls
200 PORT command successful
425 Can't build data connection
ftp> ls
200 PORT command successful
425 Can't build data connection
ftp> Terminated
I am not firewalling the port at all, tried disabling every firewall
rule just in case to no avail. Neither box is behind a NAT of any kind
(the backup system or the Mikrotik.) There seems to be no reason why the
ones that work DO work.. and the ones that don't work DON'T.. they both
have identical configs from a firewall/FTP perspective. Google didn't
lead me anywhere helpful. Any ideas?
