SMB/NetBIOS active on iSCSI-R3?

I just noticed that on my iSCSI-R3 box that there are a ton of ports open that I have no need for. Is there any way to disable stuff like NetBIOS, SMB file sharing, POP3/IMAP, etc? The list below shows all the stuff that is turned on by default (and I can't see anything in the web UI to turn it off)...

Thanks

Craig

Also just noticed that the LDAP server that's open on the iSCSI box supports anonymous bind so you can connect without any credentials...

Craig,

I know this has been a concern for many recently and our Research and Development Department will look into this and disable these ports, but this will take time or next releases (not sure which one). I know this is not the answer you want to here but in the mean time try using a Router/Firewall to block these ports (outside and & inside). This is a problem being a Storage system that we will have to look into.:(

Thanks Todd. Glad to hear that its on the to-do list and hopefully it will be along shortly. For us the iSCSI box isn't internet accessible, but having all the unused ports open, and particularily that anonymous LDAP bind runs afoul of corporate security policy so I can't get it put onto a production network segment until that is resolved.

An ideal resolution for this kind of thing moving forward would be to allow administrator ssh access to a shell as this stuff wouldn't be hard to turn off with a couple of .conf file changes. This is the approach the VMware guys take with their service console...

Craig

Craig,

Can you send the log file to support@open-e.com on the subject line please enter
RefID#10004850 for the ticket that we have created for you.

Thanks!

Hi Todd. Which log file do you want me to send to support? The portscan that I posted or something from the Open-E box?

Craig

Just send the whole log file.

im a minimalist which is why i bought open-e ISCSI. but instead i get all the bloat of DSS without the functionality.

dont you think that removing these un-needed services may help the performance and stability of the system?

looks like open-e is also using the default debian etch kernel?

Not sure what the complaint is DSS or iSCSI-R3? What are the un-needed services you are referring to - need details? Then we can ask others what their opinions are as well. We are looking into giving more control to the user on some of these services but at a later date. And yes we are using debian etch, this is easy to identify with the logs. What distros have you developed or have tested with results? Need more details to support the use of your discussion.

heres my nessus summary, if you want the actual report let me know:

Thats the open ports on a iscsi-r3 box. The only things I'm expecting are 3260 and 22222!

possible that Xinetd is enabled? why would I see IRC!
