I have a SMC Etherpower (SMC8432BT) that works fine under RH 5.2 but
doesn't work under RH 6.0. The link light on the hub comes on as soon as
the "tulip" module is loaded then goes off as soon as the startup scripts
try to "ifup eth0" the device. I re-compiled the kernel to have the
absolute minimum amount of drivers (modules or otherwise) which usually
solves my problems but it didn't help in this case. I'm using a HP
Pavilion 6370Z (Pentium II 350MHz) with ATI Rage Pro video board and 96MB
of memory. I would be interested in knowing what type of system you are
using. Some people don't seem to have any problems but others, like
myself, can't get the ethernet interface up at all.
Thanks,
Phil

Not quite true. Lucent and Ambient(Cirrus) providing programming
documentation. It's just that hackers don't see the value of a
winmodem driver, since it would suck huge numbers of CPU cycles. But
a winmodem makes a great telecom interface. http://linmodems.org.

2.2.9 up and running, here are two lines ...
- __u32 snd_wnd_packets = tp->snd_wnd / tp->mss_cache;
+ __u32 snd_wnd_packets = tp->snd_wnd / max(tp->mss_cache, 1);
... guess what happens if mss_cache is 0 (the first line is the old code).

That would bereave you of the satisfaction to be able to say you finally
deduced it yourself 8)
But sure, it is just that the main reference are the info files and the
man pages have to be created from that source of information. One can of
things that are more fun. Well, no comments about texinfo now ... pinfo
is pretty nice at least, I recommend it and can use info files now without
getting ulcers ...
There is quite a lot more information in the info pages anyway, not only
regarding what is available so browsing a bit is really worth the time.
Even if only to see what it has to offer and that is quite a lot.

Date: Sun, 16 May 1999 21:13:48 +0100
Please see the following link to read our latest press release regarding the
forthcoming launch of OMNIS Studio on the LINUX operating system platform.
http://www.omnis-software.com/whatsnew/press/linux.html
The beta version will be available from July 1999, with full release in
September this year.
We believe we have a real first here, as OMNIS Studio represents a true
4GL Rapid application development system that is binary compatible with
both Windows and Macintosh machines, and soon LINUX.
This means that developers are totally free to choose their preferred
development platform, and then deploy applications without alteration in
all of the above environments.
If you require any more information about OMNIS Studio, or would like to
know about some of the many commercial applications written in OMNIS
that will soon be available for the LINUX environment please don't
hesitate to contact me.

bash 2.X usually is. That is, if it was compiled with support for dynamic

Then redhat must have put man pages from elsewhere into their glibc-2.0-devel
package, because original glibc2 ships *only* with texinfo documentation.
While this is a point that could be debated separately (f.i. no documentation
on the tools for Berkeley db, no documentation on locale tools like locale and
localedef, no documentation for timezone tools like zic), *any* man page
present in a glibc2 package must have been added by the distribution makers.

That would defeat the reason why symbol versions were introduced and used.

Relax, there's nothing strange with that and it's no compiler problem :) This
results from glibc2 using symbol versioning and rpm correctly checking for
them.
To explain a bit: It used to be a major problem that when things like struct
stat changes (additional members, change of the type of members) or more
broader any change to the binary API is created you create binary
incompatibilities that could only be handled by bumping the library version,
i.e. the internal soname. This was the mechanism used on Linux up to libc5.
To overcome the problems of this approach, the glibc2 development team in
cooperation with the binutils developers took the symbol versioning scheme
implemented first by sun, extended it quite a bit and used it in glibc2.
Symbol versioning allows you to bind a symbol (i.e. variable/data structure or
function) to a specific symbolic version. That way, you can bind one symbol to
several versions or supply different versions of the same symbol for different
library versions (more accurately: different ABI versions). You may view the
versions the symbols of glibc2 are bound to by using
objdump --dynamic-syms /lib/libc.so.6
This will show you that many symbols are bound to GLIBC_2.0, meaning "hasn't
changed in glibc 2.1" and quite a few bound to GLIBC_2.1, meaning "new or
changed in glibc 2.1".
For a detailed description of the mechanism used and how one could use it in
ones own code, see the ld texinfo documentation, node VERSION
info (ld.info)Version
Hope that answered all of your questions ;-)

Reply-To: [EMAIL PROTECTED]
Please read on, you've probably never run into this before!
As you may have noted from the subject heading I'm experiencing a
very strange problem with my newly upgraded Redhat 6.0 box. It's a Pentium
133 on an ethernet, kernel version 2.2.9.
The problem is that when I connect to it from home (over a 14.4 modem, ppp
connection) from either windows or linux (rh6.0), everything runs slowly
and by slowly, I mean at the processing level. For instance, I did the
following timings of a clean mutt source tree compilation:
These are tcsh time results (default output). I took the trouble of
labeling some of the relevant fields, so you needn't run off to the tcsh
man page.
>From office:

As you can see from home the compilation takes roughly 8 times longer. I
can think of no reason for this whatsoever. The connections from home are
made using ssh or ttssh, but I don't think ssh is the problem.
Interestingly, I tried logging in from a few other boxes on the same
subnet at the problem box and got differing results. From one machine,
again over ssh, the timings are normal, on another the timings are slow.
They are both rh5.1 boxes. All connections via ssh.
I've been administrating linux boxes for a few years now and cannot think
of any explanations. Any ideas anyone?
thanks,

Hi there,
I would like to use the videoteXt program that is e.g. shipped with SUSE
6.1, Kernel 2.2.5.
I had the whole software-/hardware-system working under kernel 2.0.xx.
But now I upgraded my system and the kernel-module does not compiled
under kernel 2.2.5.
The module is pretty short: just one file with about 1000 lines of code.
I would be glad, if someone having kernelexperience could take a look at
the code and help me fix it.

A normal Minix installation uses so-called "subpartitions" within a
primary partition. The first sector of the partition contains an
ordinary partition table that subdivides the partition into four
subpartitions for the root and /usr partitions that Minix needs.
Linux can't access those subpartitions directly, but you can get around
this by using loop devices. Something like
/sbin/losetup /dev/loop0 /dev/hda3 -o 512
will assign /dev/loop0 to the first subpartition of the third primary
partition. Read <URL:http://minix1.hampshire.edu/faq/mxfromlx.html> for
more.

I'd guess that the machine which is suffering from the inconsistent
results, has APM power-management features enabled. The CMOS/BIOS
settings are probably set to put the system into a lower-power mode of
operation after some number of minutes of inactivity. The APM
low-power mode in question is probably reducing the CPU clock speed
(either by actually slowing down the clock, or by running the clock in
short bursts and stopping it entirely in between bursts).
On a lot of these systems, "inactivity" means "no keyboard or mouse
use".
If you compile locally (from the console) the occasional keyboard
activity is enough to keep the system "awake". If you dial in from
home, though, it'll probably have been an hour or more since you used
the keyboard; the APM portions of your motherboard chipset won't have
detected any "activity" and the chipset/BIOS will have put the system
into low-power mode. Your over-the-modem or over-the-network accesses
to the machine don't count as "activity" (based on your APM CMOS
settings) and so the system runs at about the speed of an 8 MHZ 386.
When you did the test via other machines on the same subnet, and got
inconsistent result, I'd suspect that you probably had touched the
host's keyboard or mouse sometime during or before the tests you
ran... and as a result, some of the tests were done in APM low-power
mode and some in full-power mode.
Best fix is probably to disable the APM "sleep" or "standby" mode via
your CMOS setup screen. Linux already gives you most of the
advantages of this mode, because it idles the CPU during periods of
inactivity (unlike Win3.1 and DOS).
