User cannot join Multicast Session - Invalid Login

[sudburr]

Server

• FOG Version: 1.4.0
• OS: CentOS 7.2.1511

Client

• Service Version: n/a
• OS: n/a

Description

This is a problem with just one FOG server. I cannot recreate the problem on another.

All created users except for the original `admin’ account on this one particular server cannot join a multicast session when manually initiated by the user during a network boot. The response after entering a user name and password is always, invalid login.

I have verified the client machine itself is not the problem.

I have deleted all additional user accounts then recreated them and still no go. Only the one remaining account can join a multicast session.

I tried length of password, length of username, alphabetical sorting differences of username;
ie: abmin, admin, testuser

1. network boot machine
2. Join Multicast Session
3. enter username and password
4. receive:

http...blahblahblah...\boot.php ok
Invalid login!

The problem presented itself while the server was running 1.4.0-RC14, so I updated it to 1.4.0 and the problem remained.

Simply deploying an individual image via unicast the credentials are fine.

Oh geez … okay, ignore everything. There is no problem other than that the switch servicing that bench had been reprogrammed. The ports used had been set to the wrong vlan; a vlan serviced by a FOG server that didn’t have the intended accounts.

What does the multicast (fog.multijoin) boot option look like for you?

Can you do multicast with a task?

[sudburr]

Everything else ‘looks’ normal.

The purpose of using this multicast method is to bypass the need to register a machine. I have some 700 systems coming in that will require quick and dirty imaging.

We know this works on other fog servers; the question is why does this particular feature that involves authentication when joining a session fail to allow anyone but the one account to join a session on this server?

[Quazz]

@sudburr I can only assume the multijoin option has been altered, given that it’s the only thing acting up as far as I understand.

Can you post it here?

@sudburr Looks normal, is there anything in the apache error log when login fails?

[sudburr]

Nothing at all shows up in /var/log/httpd/error_log (CentOS) at the moment of the login failure … just checked it again and nothing populated.
