Hi When Suse (7) starts up, and trys to start HTTPD i get the following error. httpd: error in loading libraries: libmm.so.11: cannot open shared object file: No such file or directory I have Squid and dial on demand working. Was okay b4 I upgrade from 6.3 to 7 :-) Can anyone point me in the right direction..

This will only work if you other machines are configured to be on the same IP network (in terms of network numbers) - ie have IP addresses numbered in the same range : 192.0.0.X with the same subnet mask. Are they ? Does the ping work (I assume not ;-) Kevin.

We have calculated that workstations can be as cheap as £245 each. This consists of, motherboard, processor, memory, case, monitor, keyboard, and mouse. None of them need to be high spec. On top of this you will need either a boot ROM or a floppy drive and diskette for each station. As 100Mbit NICS are now cheap, I'd highly recommend going for them. For the server, as usual, you should go for as much as you can get. Bear in mind that it is going to be the filesystem for every terminal that it is going to serve. It will also need approx. 8MB of RAM per terminal, plus RAM for applications. The main plus point to the LTSP, is that there is not local filestore which means that there is nothing local for people to break. If the worst happens, and a terminal completely crashes, then you simply turn it off and on again. As someone who manages a 100 user Win95 network, that sounds like heaven to me. > >Robb Bloomfield ----------------------------------------- Gary Stainburn.

bootp-ing HP Laserjet Printers
by suse 12 Oct '00

12 Oct '00

This info comes from school where we have 11 network printers ( HP2100s, HP8000, HP2400) which all used boopt protocol to get their configuration from the server. Read the man pages on bootpd and bootptab. Not exactly a light read but with the attached info perhaps not so bad. Roger also advised me long ago that it must be allowed for in /etc/inetd.conf . I have just updated my linux to SuSE 7 prof. I will be installing this on my box to test it with an old HP external jet direct. To see if this works, then you can printout the HP Laserjet config page. On a 2100 just press the two buttons together and two sheets get printed out. Before it works there will be a lot of blank or default entries on the second sheet. When the printer bootps' from the network, then the entries get filled in. We use at school the ip range 180.245.138 which is Class C and uses a mask 255.255.0.0 No, we should not be using that range but it is history now and NAT works wonders. With the attached text files you will notice our ip range and mask and need to change these as necessary. A working printer is also a useful tool for testing the network, if it boots all is well, if it doesn't get out the cable tester. Hope this helps. Regards to all mike -- minkl(a)dircon.co.uk mike.clinch(a)ukuug.org School Focus responsibility This file goes in /tftpboot/hpex/, as remote1.cfg. You can rename it but you must change the referance to its name in the bootptab file. ---------------------------------------- # remote1.cfg configuration file # Reference is to be made to the /etc/bootptab file entry for the JetDirect # name: HMoff # name of printer, call it what you will # telnet: 1 # allows a telent operation to connect to it # contact: Mike , extn 5734 # just for info # allow: 180.245.138.195 # limits telnet from this ip number only # location: Big School # physical location if you need it # # set-community-name: * # can be used if needed # # banner: 0 # stops a banner page being printed This is the bootptab file from our netBSD server at school. the file lives in /etc and is read at boot time ie when bootpd starts.

Does anyone know how to set up an HP LasetJet (with a TCP/IP) to be used on the Intranet? I have printed out the menu and it says that it is 192.0.0.192 but there is no way to get at it to change the settings. I have plugged in a patch lead and tried to ping the thing. Paul

Linux Terminal Server Project
by kevin.taylor＠powerconv.alstom.com 11 Oct '00

11 Oct '00

Hi, Whilst reading LinuxUser this month (chats about embedding Linux, small Linux distros, which includes things relating to X terminal operation) I found a reference to the 'Linux Terminal Server Project'. This contains quite a lot of information and scripts, etc to setup a diskless X terminal. Looks pretty good on first glance. (wish I had found this when I was looking for information myself - oh well). http://www.ltsp.org/ Kevin.

Sheffield Linux Users Group (ShefLUG) 6.15 pm Tuesday 24th October 2000 ShefLUG Venue: Auditorium Students Union Building University of Sheffield Westen Bank Sheffield UK for location of Sheffield University & Campus Map see http://www.streetmap.co.uk You need to dial in the postcode which is S10 2TG You can also send mail to me to request a map and for information about trams and buses phone 01709 515151. Other than that you can phone me personally at 07973 682181. Tickets will be available from the Students Union office before the event. You can phone 0114 222 8777 to get hold of those or you can go to the box office at the University of Sheffield, Union of Students, Box Office, Western Bank, Sheffield S10 2TG. Tickets should be available by the the 18th of October. You can also buy them on the door at a cost of £3 each. The topic of the meeting will be a talk by Richard Stallman his talk will be about the history of GNU/Linux and the Free Software Movement. After the talk there will be a question and answer session at which time you are invited to join in. Mr Stallman is famous for founding the Free Software Foundation in 1984. Recently IBM handed over their copyrights of the S/390 Linux platform to the Free Software Foundation. The GNU project is also well known for the many other things that are in progress and the GNOME project is a good example. We do hope that you are able to attend the lecture. We need to cover the costs of hiring a large 400 seater lecture theatre and other costs which may not be evident. Those of you who do work in Universities may wish to copy this over to any internal lists that you have. For related information have a look at....... http://www.fsf.org http://www.gnu.org http://www.stallman.org http://www.sheflug.co.uk/meeting.html Thank you Richard Sheffield Linux User's Group http://www.sheflug.co.uk GNU the choice of a complete generation.

Death of a squid?
by ptaylor 11 Oct '00

11 Oct '00

Hi All: I was messing about with squid last night and trying some different options in the conf file and kept starting and restarting the daemon. I think the machine had enough in the end as it refused to start and I got messages in the X Console saying that squid had been switched off due to excessive failures. I re-started the machine a few times but it made no difference. I left it overnight on the naieve and misguided (?) belief that it would settle and come back to normal. I'm just on my way to school now to see if it worked. If it didn't, any suggestions as to how I can get it running again? Is it some sort of re-compile? Paul
