I see all your points. These were all things I had thought of.
- Autoftp and autorpm are both console tools and I want this to be a
GUI.
- I want this to be able to work with ftp and rpm sites. Kind of like
autoftp and autorpm combined. (anyone have a URL for autoftp)
- I don't want this to be linux specific. I want people to be able to
use this on Solaris as well. In this case you would look for .tar.gz
files on ftp servers.
But you are right. There are various tools that will use this. However
there is no "only" tool to do this. Across distributions etc. This is
one thing I think would be cool.
I have also been working on some code (mostly fixing an FTP library I
found) and updated my feature set. What do you think?
=============
BENEFITS:
- support for seeing if an ftp directory has changed ex: WINE
ex: monitor ftp://ftp.sunsite.unc.edu/pub/Linux/ALPHA/wine... any
changes and you will get a notification
- support for seeing if any of your rpm's have updates? via RPMFIND
http queries.
ex: basesystem-4.9-3 ->
ftp://rpmfind.net/linux/Mandrake/6.0/6.0pre/Mandrake/RPMS/basesystem-6.0-5mdk.noarch.rpm
- support for seeing if your particular distribution has a specific
upgrade:
ex: Redhat 5.2 having an upgrade for Apache
FEATURES:
- run's as a daemon
- GUI config tool (GTK)
- send e-mail on upgrade notification
- auto-download for some specific upgrades
- you can pick and choose which upgrades/applications you want to
monitor.
- support for multiple FTP servers... if one has too many users it will
automatically go to another one.
- uses rpm -i in the background
- ability to let the user use kpackage to perform an rpm install
- ability to warn the user on certain packages.
- ability to check the version after and before (via the file name) the
file is downloaded
- multiple country support
- multiple Linux distributions support
- print out all installed packages via the GUI... if any are out of date
highlight them in RED.
- file progress indicator as files are downloaded.
- support for dependency packages
- support for "ignoring" a package... no more updates.
- support for always finding the "newest" package regardless of
distribution.
- rpmfind support
- support for upgrading individual ones or all of them..
- support for a GUI rpmfind tool

None of the Win32 stuff (#include <windows.h>) will work. I am thinking
about fixing this. I know the Win32 API fairly well and sort of think
it would be cool to develop across OS with the same core API. I am
thinking about working with the WINE guys to develop a library for just
this purpose. Way off though.

I think the binary packaging of RPM and Debian is one of the major
things that distinguishes Linux from other OSes. It's an advantage
over other Unixes, and it's a major advantage over Windows.
The one thing missing is simple auto-configuration and upgrading. I
shouldn't have to know about ftp sites, I shouldn't have to think
about software upgrades. It should just work. It's a hard problem.
GnoRPM is the closest thing I've seen.

You can write a GUI for them easily enough. The real problem is that
both tools are a bit funky, they don't quite work right.

I think this is too hard. You need some meta-information that's not
available in an ftp tarball. If nothing else, you need to know the
package dependencies. It'd also be good to know types of packages,
maintainers, signatures, etc.

RPM and Debian are not Linux specific - they both work just fine on
other Unices. The only problem is that so far no one bothers to
package much Solaris software that way. Build a tool that gives an
incentive to use a package tool on Solaris, and the packages will come.
There's a lot of good work between rpm, dpkg, apt, alien, autorpm, and
rpmfind. What's missing is a good glue to hold them all together in a
simple, straightforward, and most-importantly *correct* way. GnoRPM is
getting there, I'm disappointed that Redhat 6.0 didn't go further with
it.
>I have also been working on some code (mostly fixing an FTP library I

ftp libraries are easy. I think the important thing is to focus on the
sysadmin issues. If anyone is seriously interested in pursuing this,
let me know and I'll tap out some ideas I have for a tool like this as
a basis for a new (value-add) Linux distribution.

Has anyone written a program to access the Enhanced Parallel Port
on a PC using LINUX. I currently have a dos program and would like to
move it to LINUX.
I've checked the HOWTO's and searched the linux web sites but have
found nothing. Can anyone confirm if a driver exists for the enhanced
parallel port and where I can get some information about it.
Thanks

That's probably because one of the listed dependencies in turn depended

don't bet on it. The students here had to program in 68K assembly

It didn't work. So the poor students ended up fighting over limited

Might save the most headache because some of the things may not work

Reply-To: [EMAIL PROTECTED]
Hi,
I am suppose to build an application that perform a lot of statistics
about a PPP connexion ! For this purpose, I would be able to talk to the
modem via AT commands during the ppp connexion. According to me, a great
solution would be to create a virtual com port, with which pppd will
talk instead of the real one. A program would redirect all data recieved
on the virtual com to the real one, until the moment I want to talk to
my modem. Then we enable CTS to tell pppd to resend later data and we
stop redirecting data to the real port ! We can now send +++, and AT
commands to the modem to the modem ! After this, we would return in
online data mode, redirect again the data and disable CTS !
Does anybody know if there is already such an application ? Does anybody
find good this idea, think it's possible, and can giving me advises to
build this application ? Does anybody have an other (better or not)
solution ?
Thanks !

Hello,
We have several Dell Dual Pentium machines connected with 100MBit
ethernet. They have the 3Com 3c905 card.
I would like to send raw ethernet packets between two machines at a
low level. I mean without using high level protocols like tcp, ftp or
similar. I would like to know whether there are example programs at both
ends of how to do that. Or at least some guidance of where I should
start.
Thank you,

... and you might look for updated-2.01 (or better). It is a bit
confusing but previous versions started two programmes. Since all the
bdflush functionality is built into the kernel a simple updated does
the job. If it is okay with you, you can even run the assembler
version that does nothing else than to call sync() every 30 seconds.
I'd never trouble including machines that used to run 24/7 while I
was on holiday and such, so I'd say go for it.

The video4linux (bttv.c) has the mmap routine defined for the mapping....
The network devices don't have a mmap routine listed as a possible device operations
(in netdevice.h). Does this mean it doesn't support it or some one didn't define
such an operation for network devices.
So what do I do? Do I add the mmap routine to the list of operations defined for n/w

That's the whole point. Since glibc-2.1 is very close to completely
binary-compatible with 2.0, they decided *not* to change the soname.
If they had bumped it up, you would have to recompile *everything* to
use the new lib; as it is, most things work fine and a very *few* apps
and libraries break. (And they mostly break because they used verboten
symbols like __setfpucw).
The glibc2 maintainers had three choices: (a) bump the soname, thereby
not letting people run old apps on the new library without recompiling,
even when they would have worked fine; (b) meticulously make 2.1 100%
bug-for-bug compatible with 2.0 at the expense of things like code
cleanliness, or (c) try to make 2.1 compatible with 2.0 and accept the
reality of a few things breaking, mostly badly-behaved apps.
They chose (c). I agree with them since 2.0 was never mean to be a
"production" release anyway. For what it's worth, I don't think any of
the three choices would have pleased everybody.
