Problem:
You want to use lftp to access a FTPS server, but you get an error message like this:
mirror: Fatal error: Certificate verification: certificate common name doesn't match requested host name ‘mydomain.de’ (C8:98:BC:01:1E:FF:08:CB:62:08:6B:F1:E8:4C:1F:13:0A:3B:D8:06)
Solution:
You can use the following command in lftp to disable certificate verification:
set ssl:verify-certificate false
Inside the lftp command line, you can run the command and then retry the command that caused the error message. As lftp has a memory of which commands you used before, just press the Arrow up key multiple times until you see the original command.
Example:
lftp [email protected]:~> mirror . MyBackup mirror: Fatal error: Certificate verification: certificate common name doesn't match requested host name ‘mydomain.de’ (C8:98:BC:01:1E:FF:08:CB:62:08:6B:F1:E8:4C:1F:13:0A:3B:D8:06) lftp [email protected]:~> set ssl:verify-certificate false lftp [email protected]:~> mirror . MyBackup [...]
In case your server doesn’t actually support FTPS, you might need to use the set ftp:ssl-allow no command to disable FTPS entirely.
