On a properly maintained system:
/usr/src/fileutils*/ or /usr/src/bin/ls/
and
/usr/src/procps*/ or /usr/src/bin/ps/ (heck, it was a _long_ time since I've
looked at the last one - /usr/src/*/ps/ may be a safer bet).
If you are a lazy bum and didn't install the sources - do that.

Subject: Finding XID of RPC request
Date: Wed, 17 May 2000 23:18:43 -0400
I'm hacking a user-level NFS daemon to talk to a distributed object
system. Unfortunately, the remote calls performed by this system to
complete NFS requests may be take quite a while (or timeout). So, I've
implemented a request reply cache so I don't have to repeat completed
requests. (I'd like to avoid kludgy fixes like setting NFS timeouts.)
In implementing the cache, I need (I believe) the XID of the incoming RPC.
I'm looking at the SVCXPRT and rpc_msg structs. From rpc_msg, I can get
the XID as 'rm_xid'. I believe this worked fine at one point. We've
since upgraded to the redhat 2.2.14 kernel (on x86). Now I'm seeing a
value of 0 for this field. I've initiated 100s of requests and the value
was always 0. (These were consequent requests.)
I've tried digging through the source, and if I'm reading correctly,
XIDs of 0 should be QUITE rare. This from xprt_request_init in
.../net/sunrpc/xprt.c.
Briefly, XIDs begin at CURRENT_TIME << 12 and are incremented by 1.
Eventually, this will wrap to 0 and be reset to CURRENT_TIME << 12.
Can anyone suggest problems with my strategy or with the kernel? Is there
a better way to obtain an RPC's XID?
Thank you,
Brian

Another program to try is wvdial. I've always set up my ppp connections
by hand, editing all the scripts, etc. I got pretty good at it. On a
whim I tried wvdial and it worked automatically.
Install wvdial.
Type wvdial.
Bingo, after the one time config, you're connected.

I would not judge it the best way, but for most parts of the driver,
that should make no difference. I am doing this the traditional

kernel, put the kernel onto a disk and boot it on a second computer. I
do not have that much faith in my kernel level programming facilities,
that I would risk my current development environment by testing my
driver on it.

I would not make two modules, if I am not forced to do so. I would put
it all into a single module. If your drivers needs both modules to
work properly, you will gain nothing in splitting them. But you will
have the additional trouble of getting both modules loaded.

Not really, a DLL corresponds most closely with a Unix shared library --
it's user-space code that is linked into user programs when they are
executed.

It might be appropriate to split the functionality into an actual kernel
driver module and a shared library that provides higher-level functionality
on top of the driver-implimented system calls.

Subject: Stack size in gdb/ddd??
Date: Thu, 18 May 2000 05:14:25 GMT
Gdb/ddd does not seem to show stack size in backtrace.
Do you really have to compute the size of each frame
manually looking at the function name, then its parameters
and local variables????
Is there any way to find out the maximum stack size for
all the test cases executed? One way would be do break
at each function and examine the stack - but this not
practical for large number of test cases and functions.
Is there any way to automate such a operation in gdb/ddd?

For sufficiently bizarre definitions of free.

There is gnorpm which seems roughly the same as kpackage, but the KDE
filemanager starts kpackage in install mode when you click on
a *.rpm file. Gnorpm has an install mode but doesn't seem to
take filenames on the command line.

I've seen the claim that they are all GPL'd. Didn't matter that
much to me - the iso is available for download so they are at
least free in the usual sense.

I haven't touched Debian since my first experience with dselect in
1996 or so. I'm sure it has improved since then but I couldn't
deal with their attitude about how much better dpkg/dselect was
(when it didn't even work on a lot of systems) compared to rpm.
I'd be very surprised if that attitude every goes away to a
point where they would share rpm tools with RedHat.

The biggest problem with rpm's on debian is that the dependency databases
for rpm as compared to the dpkg/apt ones are completely incompatible.
however, debian's distributions do currently contain the 'rpm' program as
well as 'alien', so you can convert an rpm to a .deb... debian has strived
to make the dpkg system work completely, in such a way that debian's
children (stormlinux, corel, libranet, et cetera) are all fully compatible
with debian. Any of these systems could be updated to debian with little
effort through the apt-system, and That would work reversely. Also, apt
could check each of the mirror sites for each of these distributions, and
update packages from all of them just as effortlessly. (Don't argue with me, I
had a concurrent debian-Woody/StormLinux-Rain system for a while). That's a
level of consistency that RedHat with it's SuSE/Mandrake/Caldera spawns can't
compete.
I've had to install some rpm packages on my debian system before, and it's
not hard to do, but it annoys me just the same that nobody ELSE supports
any package format but rpm.

Fte is truly a Wonderful editor, and by far my favorite for programming use
in linux. (Hey, I never thought i'd say it, but color-coding things CAN
come in handy! ;)
Joking aside, it's a wonderful tool for programming, and plain editing. i
have my VISUAL environment variable set to it, and do much of my editing
with it, Though my quick-n-dirty(TM) edits are done in Vim.

Simply because there is no need for a defrag. The filesystems used under
Linux (and most/all recent versions of Un*x) have automatic
defragmentation built-in in that they prevent defragmentation, as long
as the filesystem is not 100% full.
E.g. ext2 (and ufs) partition a filesystem into cylinder groups and the
filesystem code tries to allocate blocks of a file in the same cylinder
group.

Unless you plan on porting KDE to Windows, KDE is totaly free. It is
only the Windows version of Qt that requires you to buy a license.
And even then, you only need it if your program isn't GPL.
There is also nothing preventing someone from porting Qt to Windows as
a seperate version from Qt Professional Edition.
