Hi Marius,

Thanks for the note. The link you pasted is how I came up with the config in the original question. However it doesn't work...it kept saying my password is incorrect. :-(

$ sftp  -oKexAlgorithms=diffie-hellman-group14-sha1 -oPort=2222 bioinfoadmin@localhost

bioinfoadmin@localhost's password:

Permission denied, please try again.

bioinfoadmin@localhost's password:

Permission denied, please try again.

bioinfoadmin@localhost's password:

Not sure why this would happen. :-( Have you seen this before?

Cheers,

Rui

Hi Rui,

there's a fairly complete explanation and example in in https://docs.galaxyproject.org/en/latest/admin/special_topics/ftp.html

Hope that helps,

Marius

Hey Folks,

I tried a few times with different configurations, but none worked. Did anyone have the successful experience that could share? :-)

Cheers,

Hey Folks,

I'm looking at the instructions of using ftp with proftpd. There is a section talking about extending it to use sftp. However, the sample config isn't comprehensive. I'm wondering if anyone has a working config for reference?

What's the setting of user and group? It says it should match the one in the SQLNamedQuery, what does it mean exactly? I start proftpd as root, but start galaxy as bioinfoadmin(normal user with sudo).

Just fyi, my proftpd config module and config file are pasted below. I'm working it out on a trial and error fashion, please feel free to point out if anything is wrong!

Cheers,

Rui
