unable to change listen address of admin server
Last modified: 2015-12-07 11:35:09 EST
Description of problem:
the directory seems to be unable to store a different listen address for the
admin server, than the ip address of the first interface avaible.
neither can it be configured over the configuration of the admin server in the
console, nor in the directory itself.
Version-Release number of selected component (if applicable):
I'm using fedora-ds 1.0.2-1 on Fedora Core 5 (regularly updated)
seems to be reproducible everytime, as i already described this problem on
#fedora-ds, where that problem could be reproduced by some users.
Steps to Reproduce:
1. open the admin console
2. open the admin server part from the server group
3. try to set any other ip than the address of your first interface
it doesnt work, neither if you do it the console way, nor the directory way. i
just can't set any other ip! if i try to set the listen address in the apache
config file (console.conf), it works and listens to the correct address, but the
console doesnt work anymore: it initializes and authenticates successfully, but
if i select the admin server from the server group, it says the admin server is
the admin server should be able to listen to any other address ip address than
just the one of the first interface avaible, and that means to ip aliases too!
the error messages are:
in the admin console:
Attribute[configuration.nsserveraddress] has invalid value
and if i try to set it in the directory, i get:

Ok, did a little triage on it.
The bug is in adminserver/admserv/cgi-src40/config.c in the function validate_addr()
It looks like it is trying to restrict the IP address to the hostname of the
machine (as determined by PR_GetSystemInfo()).
So the question is, do we do away with this and let the user hang themselves if
they enter the wrong address?
Sounds like we should fix it to allow the user to specify any valid IP address
or hostname. Not sure what other possible console or other code this may break
i have no clue about the functions you should or shouldnt use, but what about
getifaddrs(), i think it's avaible on linux and freebsd, but i don't know how
portable and threadsafe and whatyouneed it is :)

> The bug is in adminserver/admserv/cgi-src40/config.c in the function
but does this explain the error if i try to change it in the directory itself?

Patch to bind to the IP address
Here is one way to do it. PR_Bind to the IP address on a random port. If the
address is valid then we should bind ok. If not it will fail. I'm not sure
whether we care *why* the bind failed but this function doesn't really have the
capability to return an error message so we're a bit limited.
Set to localhost correctly.
