I'm not sure that Apache/mod_python would pick up on the PYTHONPATH environment variable, you might have to use some mod_python configuration parameters in your Apache config to specify the python path. A better approach for an installation from source on Ubuntu would be to add a file in /etc/python called 'sitecustomize.py', and add something like this to it: import sys sys.path.append('/usr/local/nav/lib/python') This module will be loaded by all Python programs that are run on your Ubuntu system. On another note, you should try the Debian package of NAV on Ubuntu. I think Ubuntu is similar enough to Debian for it to work, and it would make life a lot easier for you (dependency-wise, anyway). -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 12:48:56 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 12:49:02 2007 Subject: [Nav-users] LDAP Authentication In-Reply-To: 4ddd24660703120903gc499f13gfacb5ffaf19eba9c@mail.gmail.com References: 4ddd24660703120903gc499f13gfacb5ffaf19eba9c@mail.gmail.com Message-ID: 45F932A8.5080702@uninett.no Greg Cooper wrote, On 12-03-2007 17:03: > Is anyone using LDAP to authenticate users on the web interface? > > if so, how did you go about doing it? First of all, take a look at this URL: http://metanav.ntnu.no/moin.cgi/LdapAuthentication Second of all, NAVs LDAP authentication ability is somewhat limited yet. It was modeled after the LDAP schema used at NTNU, and isn't quite configurable enough to suit any kind of LDAP schema people might care to implement. Specifically, NAV will grant access to all users in the configured subtree, which is not always desirable. At NTNU there were separate subtrees of user accounts for different systems; there was also a subtree of NAV accounts which contained only a fraction of the total amount of users. It also makes assumptions about which attributes are used to store account names and user names, etc. Fixing this isn't a very high priority at the moment, but if anybody cares to do something about it, the code is located in subsystem/webFront/lib/nav/web/ldapAuth.py . Patches will be greatly appreciated :) -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 13:33:08 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 13:33:11 2007 Subject: [Nav-users] Cricket/NAV problem In-Reply-To: 4ddd24660703121031h716cb122q8cee4ba790fc632@mail.gmail.com References: 4ddd24660703121031h716cb122q8cee4ba790fc632@mail.gmail.com Message-ID: 45F93D04.4080707@uninett.no Greg Cooper wrote, On 12-03-2007 18:31: > I have some netboxes with IP/Hostnames in my /etc/hosts file.

When I go through > Cricket and browse to that box, I see the stats and it works fine. > Is there something I can do to fix this? I have a theory about what's going on. If you add an IP Device to NAV, and NAV is unable to do a reverse lookup of its IP address, it will use the device's IP address as its sysname (NAV always uses DNS names in the sysname column, for some old, obscure reason). So when makecricketconfig.pl generates cricket configuration, it sees that the name of the box is 10.8.250.3, and creates config based on that. It also registers in the rrd_file table that /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/10.8.250.3/9_16.rrd belongs to this box. Then, later, NAV is able to perform a reverse lookup on 10.8.250.3 and sets the sysname of the box to DNS_NAME. Next time makecricketconfig.pl runs, it creates a cricket config entry for DNS_NAME, and ignores/discards the old 10.8.250.3 config. It also registers that /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/DNS_NAME/9_16.rrd belongs to this box. So now, the rrd_file table says that there are two RRD files for the 9_16 interface of DNS_NAME. One of them might no longer exist, but it might sort first in the table, making the IP device browser attempt to use this file instead of the real one. I think you can fix it by running "cleanrrds.pl -r", which removes any entry from rrd_file that doesn't correspond to an existing file in the file system. This is just my best guess, though. I don't know why /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/10.8.250.3/9_16.rrd disappears, though, as nothing in NAV deletes that. It might never have been created (e.g. makecricketconfig was run, but Cricket was never run until the DNS name had been resolved and makecricketconfig ran again). -- mvh Morten Brekkevold UNINETT >From annaliu at us.ibm.com Sat Mar 24 10:42:11 2007 From: annaliu at us.ibm.com (Anna Liu) Date: Sat Mar 24 18:42:24 2007 Subject: [Nav-users] Question in Configuring NAS Message-ID: OFA51A9242.C09767EA-ON882572A6.006D229B-882572A8.00613DBD@us.ibm.com I'm new in NAV.
