Hostgroup shows Error on creation

Hi,

I try to create a hostgroup for firewall rules.
First I added the hosts at the “Hosts”-Tab.
After that I switch to the “Host groups”-Tab and want to create a new Host Group like this:

When I click on Submit, I see this:

What the message wants me to do?

Hi, why on the second screen there are no Members?
Also please share Host page :slight_smile:

Here it is:

I don’t know why the members are missing after the “Submit”

Edit:
Problem exists with IE11 on Windows Server 2012 R2 and Chrome (latest) on Windows 10

Edit2:
It must have something to do with the hosts. I created another group with other hosts. That worked.

OK, I got the Problem.
I cannot create Host Groups, with hosts, that have an underscore ( _ ) in the name.
Definitely a bug :wink:
If it is the GUI or the moduls behind the GUI, I don’t know :slight_smile:

You’re right, this is an inconsistency of validator between pages :confused:

IIRC the “_” (underscore) is not allowed in hostnames :no_mouth:

No longer true, RFC 2181 permits underscores in hostnames.

ok for DNS; I’m pretty sure also Linux allows an underscore in host name. @Hunv, what about Windows?

For NetBIOS:
Everything is allowed except /:*?"<>|
The Period (.) has a special function.
Underscore is allowed

For DNS:
Only Alphanumeric, minus (-) and period (.) (with special function).
Underscore is NOT allowed

and some more where it is OK and where it is not OK.
Because it is not OK for DNS: Don’t do it.
