Client for Ubuntu Server o Linux Server

my query is: there is some client of owncloud for linux server, without desktop. and configured from the console. Thank you very much

Have you tried csync?

Yes, a command line client is included. But you need to start it (via cron or other means) for every sync run.

(@dmitry csync alone is just a library and not sufficient)

Is this related to this topic?

Hey, i think that user is some sort of spambot / spam-user. Note the three links to some sort of “unofficial” download pages of completely unrelated software in that post.

Yeah, you are correct. @tom42
