Date: Wed, 09 Jun 1999 19:00:07 +0000
So now could some one explain to me why even after doing multiple
low-level formats and setting the swap space to under 100MB and only
having four partitions each rather small, that I still am unable to have
DiskDruid and/or fdisk format the swap partition? Even though I have set
everything quite low, it is still not recognizing the swap partition. I
have even downloaded the latest boot.img from off the RedHat site and no
luck.
Any help would be much appreciated. Though I can reboot the machine, I'd
like to be able to enable the swap.
Sie koennen mich entweder auf Deutsch oder auf Englisch antworten, denn
ich verstehe beides.
Thanks.

download any tar.gz file and uncompress it, I can install it. I type
configure and below is as far as I can get. I am running RedHat 6.0

Thanks to the information posted to this forum, I have managed to get the
Java 1.2 development kit "mostly" working on my Redhat 5.2 system.
However, when running any Java classes, I get a warning message, saying
that the default jit cannot be found, even though it is in the "jre" tree
of the installation directory. The result, of course, is that the code is
run interpreted and is as slow as molasses, even on a 300Mhz/PII system.
If anyone has any suggestions on how to remedy this situation, I would be
most grateful.
Thanks.

Do you have msdos fs support in your kernel?
try mount /dev/fd0 /floppy. Normally it checks the filesystem itself.

That's totally not true. I use both OS/2 Warp and Linux/FreeBSD
for Java development. The lastest versions 1.1.7-1a and 1.1.8 for
FreeBSD are excellent. Like all things it's performance depends on your
platforms setup. I use 128MB/256MB Swap and the only java
setting I use are in /etc/profile as described below.
export JAVA_HOME=/usr/local/java
export SWING_HOME=/usr/local/swing
(add /usr/local/java/bin to $PATH)
Swing-1.1 also runs excellent under Slackware and FreeBSD3.2.
(Note: I use libc(5.4.46) under Linux and Metrolink Motif 2.1)
I have had bad luck with glibc in general. I am waiting till
2.1 on Slackware then you will know it is stable.
TowerJ purports to be faster than OS/2 Warp 4.0 (which is the
top performing Java platform) on Linux. I am currently testing
it. It seems most promising.

When I run "javac" from the Linux port of JDK 1.1.5 it crashes (see
below). It makes no difference if I call it with parameters or not.
Running "java" works fine.
I obtained the JDK from the RedHat 5.1 CD. I am using RedHat 5.1.
"uname" reports my kernel as 2.0.34.
Advice and assistance gratefully received.

About 2 years ago I downloaded a multi-boot utility that was quite
neat. Now I've multi-patitioned my machine again, and I was searching
for the same one, but can't find it anywhere. I cannot remember the
name, or where I downloaded it from. (I just know it was the author's
home page, not a commercial site.) I hope someone recognises it, and
can tell me where I can find it.
It completely fits into the MBR.
It has 5 or 6 (maybe more) MBR images, for different purposes, e.g.
one to boot the last OS that was loaded,
one to always boot the same one
one with short descriptions, and more options,
one with longer descriptions, but fewer options, and more...can't
remember all
It was able to go to the next hard drive and read the partition table
for that one too, and boot any bootable OS'es on hdb/c/d too.
It was customisable, you can enter your own description for each
bootable partition, select the time before it automatically boots the
default OS.
I'd appreciate it if anybody that knows where I can find this one again
can let me know
Thanks in advance

Wrong. Once control is passed on to any code, and it takes control of the
system and it's functionality (memory allocation, I/O, etc.), then it is an
OS. Just because it can pass control onto something else doesn't mean it
is not an OS.

No, their trying to be backwards compatible with a lot of customers and
older applications. It would make their life a lot easier, and more
profitable, if they could spend less time trying to shoe-horn in all the
backwards compatibility crap. Software companies would like nothing better
than to through the latest version out and rewrite the thing again, without
the headaches of backwards computability. I've worked at a few, and on a
few apps, and this has always been the case.
You know, it never ceases to amaze me that so many people, such as
yourself, believe that companies such as Microsoft, who do have some degree
of talent, would put in a lot of extra time and effort to screw you around.
I think there's a psychological term for people who believe their being
singled out, but I can't remember what it is...

Subject: vacation program broken for RH6.0?
Date: 9 Jun 1999 19:58:46 GMT
I've spent a copule hours trying to get the standard autoreply vacation
program to work with a RedHat 6.0/glibc2.1/kernel2.2.9 dist and it
appears something is broken. I've built vacation-1.2.0 and a couple
older versions and I can get it to segfault sometimes, other times it
delivers an empty message.
Here's the last few lines of the output of
cat test.msg | strace vacation orf
where test.msg is a normal email message as it would appear in the
spool.
open(".vacation.msg", O_RDONLY) = 3
pipe([4, 5]) = 0
recv(-1, "\205\300}!\350\222\357\377\377\213"..., 4294967295,
MSG_DONTROUTE|0x40109db0) = 3801
close(4) = 0
fcntl(5, F_GETFL) = 0x1 (flags O_WRONLY)
fstat(5, {st_mode=033015, st_size=0, ...}) = 0
mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40015000
_llseek(0x5, 0, 0, 0xbfffeb18, 0x1) = -1 ESPIPE (Illegal seek)
write(5, "To: [EMAIL PROTECTED]\n", 27) = 27
close(5) = 0
munmap(0x40015000, 4096) = 0
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
What's up with that illegal seek anyway?
Sometimes it will exit "normally" (not dump core but send a blank
message) instead of SEGV.
A code snippet from vacation.c (version 1.2.0):
sfp = fdopen(pvect[1], "w");
fprintf(sfp, "To: %s\n", from);
while (fgets(buf, sizeof buf, mfp)) { /* PROBLEM is here I think */
char *sp, *fromp, *subjp, *nextp;
subjp = strstr(buf, "$SUBJECT");
#ifdef DEBUG
if (subjp) {
sprintf (logline, "sendmessage: found $SUBJECT %s\n", subjp);
printd (logline);
}
#endif
.
.
.
I did some debugging and the fgets sometimes immediately returns a null
pointer, which should not happen. Either way the debug message is never
printed, as it's popped out of the while loop immediately.
I have a feeling this might be a glibc problem. I have recompiled many
times but to no avail.
I'd just use procmail but I like the database that the vacation program
uses to avoid sending replies more than once a week.
