[Problem] Storage Node connection issues after updating to FOG 1.6

[Fog_Newb]

Hi all,

Not sure if this is a bug but…

I recently upgraded my FOG server (running in a VM on Ubuntu 24.04) from 1.5.x to 1.6. The upgrade process went smoothly with no errors, but afterwards I ran into a problem: the Default Storage Node could not connect. In the Web UI, “Test Connection” kept failing with an error about username/password not matching.

Here’s what I’ve done so far to troubleshoot:

Checked the .fogsettings file – confirmed the management username (fogproject) and password were correct.

Verified FTP manually – I was able to ftp localhost as fogproject using the same password, and it worked fine.

Checked the database – logged into MariaDB and confirmed that the nfsGroupMembers table had the correct ngmUser and ngmPass matching .fogsettings.

Looked at the hostname – saw that ngmHostname for DefaultMember was set to the server’s LAN IP (10.1.1.100). I tried updating it to 127.0.0.1 instead, restarted the FOG services (FOGImageReplicator and FOGSnapinReplicator), but the connection still fails.

Restarted services and re-tested multiple times, no change.

Here’s the output of systemctl status | grep FOG showing all services running:

├─1082 php /opt/fog/service/FOGSnapinReplicator/FOGSnapinReplicator
└─1137 php /opt/fog/service/FOGSnapinReplicator/FOGSnapinReplicator

So far, I’ve confirmed:

Credentials are correct (FTP works).

Database values match .fogsettings.

Tried both LAN IP and 127.0.0.1 as hostname.

All FOG services are running.

Still unable to get the storage node to pass the connection test in the Web UI.

Has anyone else run into storage node connection issues after moving to the 1.6 branch? Did something change in how the node authenticates compared to 1.5.x?

Thanks for any advice!

@Fog_Newb 1.6 prefers using SSH access for SFTP connectivity to the Nodes:

Can you output your /etc/ssh/sshd_config file? I suspect the sftp line is screwy at this point.

[Fog_Newb]

@Tom-Elliott Oh

sshd.txt

[Tom Elliott]

@Fog_Newb Yep, it’s as I suspected:

The Line:

Subsystem	sftp	/usr/lib/openssh/sftp-server

should be changed to:

Subsystem	sftp	internal-sftp

Then restart ssh services: systemctl restart sshd

Then your Storage Node testing should succeed!
