Re: Maintaining multiple Debian boxes
Dale Scheetz scripsit: |Wow! Bet that keeps you busy ;-) Less than you would think, honest, I am doing a PhD at the same time ;-) |You might want to check out DoList in the upgrades directory. This script |runs dpkg from a list of packages that have been properly ordered to |resolve the dependency issues. Once you have a working list (check out the |base.list file as an example) you can run DoList against it and your |package archive to do repetative upgrades. If your 56 machines are |networked together, then you only need to keep the archive on one machine |and mount it nfs on the target machine, run DoList and you are done. |At the moment this is still not effortless, because of the various |questions that packages ask during installation. But this problem is being |worked on by others and should be resolved soon. I have: it is almost there but not quite what I want. One of the problems is the way upgrades need to be done. I understand that 99% of the developers don't have more than 4-5 machines on which Debian is running so the problem isn't felt but please try and go into multi-machine mode as you read on. dselect is out: interactive, hence useless. dpkg via rsh from a single trusted host (or ssh) isn't bad, only needs the packages to be NFS mountable and our local mirror allows NFS mounts for hosts within the UK (the academic net is a 33Mb/s ring over the UK so we don't have bandwidth problems as long as we don't leave our cosy neighbourhood). The problem, as you mentioned, is the answering of questions, a real pain, _and_ the fact that some configuration files are modified without telling the user (cf. my mail on /etc/X11/Xservers). Also, most packages, once upgraded need a reboot to be running clean, e.g. sendmail which isn't stopped during upgrade (this is criminal BTW since you then proceed to modify the .cf file...), this is not good for multi-machines 'cos I have jobs running and people to take care of... Finally, what about the extras? For example, without /etc/environment with LD_PRELOAD set to the GNU malloc I couldn't get xrdb to work in the first incarnation of X 3.2 - changing it on all machines meant an rdist, no problem... Basically my real problem is that I cannot find a coherent upgrade strategy, something which would be very nice is a dry run option to dpkg and dselect, i.e. pretend and show me problems, then I can see it before I mess up... Also a verbose mode where it shows me file modifications, this would have helped me catch the /etc/X11/Xservers problem before it hit me. Once I have an optimal dry run I can then write a script which does the nifty things by hand, like upgrading the libc first to save dependencies or something along those lines.

LaserJet IIIp and apsfilter
Hello all, I have a problem with a LaserJet IIIp and apsfilter. It is my understanding that the memory requirements for 300x300 are of 1.5Mb and the standard box comes with 1Mb, i.e. I am limited to 150x150.

[Update] X 3.2 login problem
Hello all,
sorry for the previous rushed message. So, the problem is
better described as follows:
o login from virtual consoles is OK, both local and NIS accounts
o login from X11 results in Login incorrect both for root
(clearly local) and NIS accounts. Passwords have been checked
n times including setting them to something trivial and trying
again.
o Machine is now running 2.0.27 (just in case TM) and it makes
no difference except that the keyboard does not lock-up any
longer under X startup.
o X server is stock XF86_S3 coming in the 3.2-1 package, xbase
is 3.2-1 too (all taken from mirror at ftp.funet.fi).
o No error messages in any of /var/log/{messages,auth.log,
debug,daemon,xdm-errors}.
o System works fine with startx (clearly an authentication
problem).
o libpam was installed but removal made no difference.
Any ideas urgently welcome (including how to get all the way
back to my old 3.1.2...),
Thanks,
Arrigo

XFree 3.2 International Users HOWTO
Hello all, this message is intended for those of us out there who _don't_ have a US keyboard and are installing XFree 3.2. If you have a US keyboard ignore all that follows. To begin with I assume you have a relatively up-to-date Debian tree, i.e. all X stuff is version 3.2-1 or better. What you will want to do, immediately, is to make a safe copy of your XFree 3.1.2 configuration, to do this simply do cp /etc/X11/XF86Config /somewhere/safe/XF86Config Then install the XFree 3.2 packages _including_ the xext package which contians the dreaded XKBD extension which we will need. Now, you will notice that the installation will not ask you any questions as to converting your 3.1.2 config file to 3.2. This is the catch: let us assume that you have a password with the '@'. Then in the UK, for example, the '@' character sits where in the US they have the '' character and vice-versa. Let us assume that you run xdm. Then although you were used to X getting your keyboard right it will get it terribly wrong and you will not be able to log in - unless you know where all the characters sit on a US keyboard. How do you fix this? Simply run xf86config, install the keyboard that you need and then, once it is done, edit the config file: /etc/X11/XF86Config (as usual). There are a few changes, for example new video cards, so it might be a good idea to install a new config file from scratch. But, if like myself you have a 1152x900 100dpi mode you are particularly fond of you can recycle the old 3.1.2 XF86Config from the Monitors section onwards without any changes. Save this new config file and restart xdm. You will get back your proper keyboard mappings and be able to log in.

this didn't use to happen... It is quite serious as Mail, for
example, when trying to save the mbox complains about not being able

Any clues? I have the frozen tree as of Friday 29th November.

Fortran I/O problems
Hello all, just to continue the Fortran saga: it looks suspiciously like the I/O library in f2c and g77 both don't do buffered I/O any longer. This differs from the standard behaviour on other platforms where the WRITE statement produces buffered I/O. Could this be a side-effect of the 5.4.x library? The problem is shown by jobs which have I/O, even to a local disk which never attain 90% CPU usage on the machine. Watching the data with tail -f shows that data is written continuosly, without any buffering of any sort. Please note that the machines are 166MHz pentiums with 430HX motherboards and fast EIDE disks and 64Mb of RAM, i.e. the stuff should be buffered by Linux in any case. The boxes are running Linux 2.0.25. I have a situation where the processor is idle 56% of the time, system usage is at about 1% and jobs only get 40%ish. The same jobs on other boxes (Suns running SunOS or Solaris, DEC alphas with OSF) constantly stay at 90+% cpu usage. A typical vmstat line is: procs memoryswapiosystem cpu r b w swpd free buff cache si so bi bo in cs us sy id [...] 1 0 0 3544 992 304 5340 0 001 152 121 40 2 59 Not very impressive...

g77 f2c serious problems
Hello all, people here are having very serious problems with both g77 and f2c: the numbers which come out at the end are different from any other architecture we can lay our hands on, i.e. they have declared the boxes unfit for numerical calculations. This is a pretty major problem because the whole idea of getting Linux on fast PCs was to offload the main Unix boxes from jobs. Now the question is: am I the only one seeing this problem or is this a known problem which somehow doesn't make it on the READMEs and FAQs? I'd like to point out that where g77 is in alpha stage, f2c isn't and on other architectures is happily used and gives numerically consistent results with the native Fortran compilers. I would greatly appreciate any information or patches. A bug report is in the process of being prepared for both the g77 developers and the f2c developers.

C-A-Del and X
Hello all, thanks for responding via e-mail, I am now on the list, just didn't have the time to do this before. I think the optimal solution is the Tcl/Tk script, I cannot set the uid for a shutdown because the room is open access and the last thing I want is a bunch of students playing tricks on each other. Thanks to all for helping, Ciao, Arrigo -- Arrigo Triulzi [EMAIL PROTECTED], http://www.ma.ic.ac.uk/~agbt Mathematics Dept.
