wont run as root

Hi list. Im installing OOoRC4. Well updating it from Beta2 actually. So I updated the installtion on the server. Which worked fine. So then I go to update OOo folder in my home directory. But it tells me that it cant update the network version, and I have to run it from command line with -net. So I do. But then it tells me I have to run it as root, or it wont work properly. When I try to run it as root it wont work. I get this error. glibc version: 2.3.2 Xlib: connection to ":0.0" refused by server Xlib: No protocol specified ./setup: cannot connect to X server :0 Does anyone know what I'm doing wrong? Any comments welcome. Cheers -- Andrew Nix St Pauls Catholic High School Firbank Road Newall Green Wythenshawe Manchester M23 2YS tel: 0161 4375841 ext 168 fax: 0161 4982030

Yes I'm guessing you are logged in to X as a common user, and then using an X terminal to start OO, having, presumably first su'd to root. The root user has no permissions to access your X server. To overcome this, try restarting OO from within the X-term with something like: ssh -X root@localhost /path/to/the/executable/you/were/trying/to/run You will then be asked to provide the password (which should be the root user's password) and everything should start up fine.

Interesting mix... Most liberating school ICT solution added to the least! You may well find PAM with smb_auth the easiest way to deal with this (hopefully interim!) issue.

Secondly I've just been asked to add some Linux workstations to our existing RM Connect 2.3 network, I thought that I could use winbind to authenticate users to our PDC rather than add a whole load of new usernames and passwords to each Linux workstation. Unfortunately my attempts so far have been unsucessfull, my current problem is that winbind complains that 'user [domain]+[username] not known to underlying authentication module' and resets.

Hi all: Has anyone had any experience using Linux clients with Novell servers? Can anyone point me to a quick and dirty guide to read as there seems to be little in the manuals. My new school network manager is keen to try Linux integration but has little Linux experience and I have never seen a Novell server other than when playing with one during my CCAI training. Paul

Re: [suse-linux-uk-schools] address ranges

The class B address range for private networks is 172.16.0.0 to 172.32.0.0 each of which could have up to 2^16-2 hosts (65534) so probably one will do. However using such a large address space with many computers, as the numbers of computers increase so does the possibility of collisions occuring, which may outweigh the advantages. To cut down on collisions, make sure switches are used rather than hubs. Regards Bill

The use of subnets is categorically a good thing; this prevents broadcast traffic from slowing the network down and is a useful way of providing QoS - the downside is lag between subnets if you use a router rather than layer 3 switching. You also need to provide services to resolve netbios names e.g. WINS, and have a method of providing DHCP support. We use layer 3 to support 20+ class C and below subnets without any issues (W95/8,NT, 2000, XP, Linux, Unix). What concerns do you have on his behalf?

Thanks Andrew, One of the issues is that subnetting on this system bears no relationship to topology. e.g. all servers are 192.168.0.1-50; clients with static IP are 51-254. Others get IP via DHCP in the range 1.1 to 2.254 - he's treating the network as being unstructured - which it isn't. I think this is generating loads of unnecessary traffic through switches. Hence he's using subnets as a way of extending the address range rather than as a way of clustering services either physically or logically.

Just 'because it exists' is a bad reason. A good reason is where discernible groups need access to peculiar resources. These could be: a) A particular server/servers (could be special mail/file-print/proxy servers for the group of machines on the sub-net). b) Specific network printers. c) Other special shared network resources (web-cam; PLC control technologies(!!); robots; turtles etc etc). By sub-netting and locating the identified resources on the appropriate sub-net, then access is made very easy for those who share that sub-net, but not necessarily denied to less frequent users who may live on another one. In this way, each sub-net can concern itself with the resources which are *predominantly* for its users, and in a way which is commensurate with this, the network traffic is *generally* limited to those switches / routers (depending upon the methodology used on your physical network) that deal with the identified sub-net. By planning network resources around places of need, essential sub-net divisions should really present themselves. It is these that then become 'categorically' good things. Hope this helps further.
