Hi friends, I am not able to load X windows on my node. I have booted the diskless node under LTSP and I tried to load X windows. The mother board is intel 810e chipset. I have also tried with Trident SVGA card. I am briefing here under the messages appeared on the screen using both cards. Also I am attaching the lts.conf file for reference. Please guide me how to go further to get X loaded in node. XFS is running on the server when given the command ps aux | grep xfs, it shown as follows. xfs 1331 0.0 1.6 5312 4144 ?

AFAIK, you can't ... unless someone decides to write a utility which will do just that. The best way is to create an rpm out of the tarball - it's rather straightforward once you get the hang of how to create a spec-file. The only hard part is creating the list of files in it, which specifies what goes into the package. But that can be done by inspecting the output of "make -n install" in the tarball.

Philip wrote: >I'm still stuck with the loads and loads of apps that I've already >installed from rpm. How do I handle those? Here's a rather painful hack ... Assuming you still have the build trees with you, create a list of files installed using "make -n install". Use this list to create a spec file. Write the file so that rpm does nothing during the configure and build stages. The only important part is the files section, and somehow it must be able to figure out where the build tree is! Create rpm from the spec file and then do an "rpm -ivh --force" Anybody got better ideas? Maybe it is possible to use the rpm development library to write an app that can directly modify the rpm database? It could take a spec file as input and use the info to update the database ... maybe the library has a perl module as well ... Thank gawd I never install a tarball without creating an rpm first! ;-) SameerDS. _________________________________________________________ Do You Yahoo!?

Servers behind a NAT
by Satya 21 Sep '01

21 Sep '01

Should I do anything special to servers behind a NAT? For example, connections to $IP on port 81 are redirected to $INTERNAL_IP on 80, and it gives back data that indicates the real IP instead of 81... -- Satya. <URL:http://satya.virtualave.net/> As long as I can remember, I've had amnesia.

Reminder: ACM Seminar on Firewalls/IPfileter, Fri 21/9
by Durgesh D Rao 20 Sep '01

20 Sep '01

Dear Colleague, This is to remind you about the following event. Regards, - Durgesh, for ACM Mumbai ACM Seminar Friday, September 21, 2001 - 6:30 p.m. Title: Firewalls, simple & easy: IPFilter Speaker: Vivek Nallur (NCST) Venue: Lecture Theatre, NCST, Juhu Abstract: "The internet was created as an experiment. The experiment has failed" - Tsutomu Shimomura The Internet is currently a system administrator's nightmare, what with snoopy folks perennially sniffing around the place looking for systems to break into and steal the 'family silver'. What began as a dream for scientists, researchers and artists, has become a nightmare for the knights in geek's clothing. One of the more potent weapons at the disposal of these knights is the firewall. Its etymological roots unknown, the current usage stems from Steve Bellovin's email to Phil Karn regarding some security device. The first recorded usage in print is in Stafford and Garfinkel's book on Practical UNIX Security, published in 1990. Simply put, a firewall is a system that enforces an access control policy between two networks. This seminar explores the installation and usage of a commonly used firewall, IPFilter. About the Speaker: Vivek Nallur passes under the guise of a scientist in the KBCS division at NCST. He pretends to be pre-occupied with issues in Data Mining, Chaos Theory and Genetic Algorithms, whilst ogling at his beloved computer all day. He's passionate about girls, patterns and reading (in no particular order). -- ---------------------------------------------------------------------------- Durgesh D Rao (DDR) | Email: durgesh(a)ncst.ernet.in Research Scientist, KBCS Division | Ph: 6201606x372(w), 7563437(r) National Centre for Software Technology | Fax: +91-22-6210139 Gulmohar Rd 9, Juhu, Mumbai 400049, INDIA.| Web: www.ncst.ernet.in/~durgesh ----------------------------------------------------------------------------

Telling rpm what is installed
by Philip S Tellis 20 Sep '01

20 Sep '01

How do I tell rpm that I have installed some packages from tgz? It refuses to install software that requires these files. With rpm, I can use nodeps, but with redcarpet, I cannot. RedCarpet requires all dependencies to be met. Philip -- You have mail.
