Hi Rui, Are you trying to set up proftpd (with sftp) to use galaxy user credentials read from a postgresql database? Do you have the postgresql part working on regular ftp? 1- The proftpd version on ubuntu 16.04's repository works fine, you don't need to compile it yourself (unless you really want/have to). An apt install proftpd-basic proftpd-mod-pgsql would do it. 2- The user and group under which proftpd runs are defined in proftpd.conf. You didn't show that part of your file, but it's these two lines: User proftpd Group nogroup 3- I see you're missing: #Before the <IfModule mod_sftp.c> LoadModule mod_sql_postgres.c LoadModule mod_sql_passwd.c AuthPAM off #Within the <IfModule mod_sftp.c> TLSProtocol TLSv1 I suppose you can specify tls 1.1 or 1.2 here, but never really tried it. In my setup I also commented out the AuthOrder line. I guess these changes should do it. Best, Tiago On 22-03-2017 08:29, Rui Wang wrote:
Hi Folks,
I'm trying to set up the ftp for the local galaxy instance. I got the regular ftp working, but not the sftp. After a few hours attempts, I'm wondering what I'm missing. Here is the related info:
1. Configure the build
install_user=bioinfoadmin install_group=bioinfoadmin ./configure --prefix=/media/libraryfiles/proftpd --enable-openssl --with-modules=mod_sql:mod_sql_postgres:mod_sql_passwd --with-modules=mod_sftp:mod_tls make make install
2. Start the server
sudo sbin/proftpd --config /media/libraryfiles/proftpd/etc/proftpd.conf -n -d 10
I notice that even though I start it using sudo, the real user that is running proftpd is 'nobody'.
3. Config file snippet, I inserted the following piece to the original config file, Add 'VirtualHost' or no doesn't change anything in result
<IfModule mod_sftp.c>
SFTPEngine on Port 2222 SFTPLog /var/log/proftpd/sftp.log AuthOrder mod_auth_unix.c mod_sql.c
# Configure both the RSA and DSA host keys, using the same host key # files that OpenSSH uses. SFTPHostKey /etc/ssh/ssh_host_rsa_key SFTPHostKey /etc/ssh/ssh_host_dsa_key
#SFTPAuthMethods publickey SFTPAuthMethods password
# Enable compression SFTPCompression delayed
</IfModule>
Now when I start the server, and then when I try to test the login, I got this:
$ sftp -P 2222 localhost packet_write_wait: Connection to 127.0.0.1 port 2222: Broken pipe Couldn't read packet: Connection reset by peer
Accordingly, I got the following segfault in log:

Seems that it is connected in the middle...
And the /var/log/proftpd/sftp.log shows things like(many identical snippets, I just picked one randomly):

The version of proftpd is 1.3.5d on ubuntu 16.04.2. Not sure if anyone has seen this before. Any input will be greatly appreciated.
Thanks, Rui
