I'm trying to get my Pelican blog working. It uses lftp to transfer the actual blog to ones server, but I always get an error:

mirror: Fatal error: Certificate verification: subjectAltName does not match ‘blogname.com’

I think lftp is checking the SSL and the quick setup of Pelican just forgot to include that I don't have SSL on my FTP.

This is the code in Pelican's Makefile:

ftp_upload: $(OUTPUTDIR)/index.html
lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit"

which renders in terminal as:

    lftp ftp://username@blogname.com -e "mirror -R /Volumes/HD/Users/me/Test/output /myblog_directory ; quit"

What I managed so far is, denying the SSL check by changing the Makefile to:

lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "set ftp:ssl-allow no" "mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit"

Due to my incorrect implementation I get logged in correctly (lftp username@myblog.com:~>) but the one line feature doesn't work anymore and I have to enter the mirror command by hand:

mirror -R /Volumes/HD/Users/me/Test/output/ /myblog_directory

This works without an error and timeout. The question is how to do this with a one liner.

In addition I tried:

  • set ssl:verify-certificate/ftp.myblog.com no
  • This trick to disable certificate verification in lftp:

    $ cat ~/.lftp/rc set ssl:verify-certificate no

However, it seems there is no "rc" folder in my lftp directory - so this prompt has no chance to work.

From the manpage:

-c commands
Execute the given commands and exit. Commands can be separated with a semicolon, &&' or||'. Remember to quote the commands argument properly in the shell. This option must be used alone without other arguments.

So you want to specify the commands as a single argument, separated by semicolons:

lftp ftp://$(FTP_USER)@$(FTP_HOST) -e "set ftp:ssl-allow no; mirror -R $(OUTPUTDIR) $(FTP_TARGET_DIR) ; quit"

You can actually omit the quit command and use -c instead of -e.

That's great. Thanks a ton. I had hoped that someone who's more experienced than me would spot my failure instantly ( - I also tried your -c suggestion leaving out the quit, but this didn't work for me. I'm happy anyway). –  pattulus Jul 27 '12 at 21:14

I had a similar issue, though my lftp does have ssl support compiled in (Fedora RPM). ssl:verify-certificate false did the trick for me.

ssl:verfy-certificate false didn't work for me, I was getting a timeout error when "making data connection".

I followed these instruction by adding set ftp:ssl-allow false to my ~/.lftprc file.

Did you spell it right when you ran the command? ssl:verify-certificate false –  Malcolm Murdoch Oct 31 '14 at 10:34

I have read man pages and found solution. Create file


and add there next line:

set ssl:check-hostname false;
