Hey all:
I would like to use Klyx for a large report, but it looks like it
doesn't support normal bitmap
type graphics. Is it possible to convert .gif or .jpg into encapsulated
postscript?
If not, what would be a could wordprocessor, abiword doesn't seem to be
very good.
Thanks

Subject: Where can I get a pre-built POSE for Linux ?
Date: Sat, 25 Nov 2000 16:58:54 GMT
I'm trying to get the Palm OS Emulator to work, but running into great
difficulty building POSE.
I have RedHat Linux 7.0.
I'm reading "Embedded Linux Journal", page 38. For some odd reason, the
month or the issue number is not conspicuously displayed on the cover,
and it has a picture of MachZ chip/board.
I installed FLTK from source as instructed. I downloaded the POSE tar
and extracted it.
After "./configure" command, when I issue the "make" command, I see
pages of text scrolls by, and at the end, I get an error "make: ***
[all-recursive] Erro 1", and a couple of other errors.
I issued the command "make install" as root, anyway, and I get a similar
error. After that, when I type "pose", I get an error that no such file
is found.
Where can I find a pre-built binaries of the POSE? Building from
source is too difficult. I'm rather surprised that pre-built binaries
for Linux on Pentium isn't readily available, considering the vast
number of people who could benefit from the convenience.
Any help would be appreciated.
Thanks.

WRONG APPROACH!
No matter how much time you spend, you can *never* be sure to have
really found all changes and backdoors a hacker could have inserted.
The ONLY way to safely recover from a root compromise is:
1. Physically disconnect the now untrusted machine from all networks
2. Backup all data you need, be sure not to copy any system binaries,
configuration files or libraries.
If you have to re-use configuration files from the
compromised host be sure to verify each and every single line for
unauthorized modifications. The safer way to go would be to rewrite
all configuration files from scratch, at least for services that
require root privileges to run.
3. Wipe all disks clean and reinstall the OS from trusted media
(CD-Rom).
Let me stress again that it is not possible to reliably determine
which "packages" have been altered! There are literally hundreds of
ways to backdoor/trojan a linux system. Not only system binaries can
be replaced or patched. Also there are malicious kernel modules and
even kernel patches of a kind that leaves all doors open for the
attacker - so he may come back months after the box has been
"cleaned".

Again: If an attacker leaves obvious mods like these he might either
be a script kiddy who doesnt really know what its doing or
- worse - expect you to happily "clean" them off your system so he
notices when his intrusion has been detected. It is a common method
to measure the skill level of the "opponent admin" by leaving such
stuff laying around (eg. an account named "rewt" or "hax0r" in
/etc/passwd) and see if the admin falls victim to the trap by NOT
choosing the "extreme way" to recover as you call it. If he doesn't
the target host may be considered a safe bet for more complex
installations (sniffer, floodnet hub, whatever) since the admin will
obviously not be able to detect these.

Very true.
Usually people wont have a 2nd host only for logging at home but there
are syslog replacements w/ cryptographic integrity checking and such.
They will do the trick almost as well.
In my opinion you already mentioned the most important rule above;
disable EVERYTHING and switch on just what you need, one by one.
Also do not allow ANYONE to login from remote to ANY service, unless
there is no way to avoid it.
Never rely only on Packetfilters, not even on a full featured DMZ.
Security must not end right after the frontline.

Its a rather simple utility to detect portscans.
It might be helpful but its not more than one piece of the puzzle.

Subject: Problems booting RH7 after install
Date: Sat, 25 Nov 2000 11:51:35 -0500
I just upgraded to RH7 from RH6.0. The install went clean but the system
will not boot from floppy or disk.
1. It's a dual-boot Windows 98/Linux config. 4.3GB SCSI disk, 2GB
partitioned to Windows (/dev/sda1), 2GB to Linux (all root /dev/sda2 with a
128MB swap /dev/sda5). This partitioning worked fine under RH6.0.
2. The RH7 install consistently overwrites the MBR with a corrupted LILO
config. I get "insert system disk" error message when I try to boot. I have
to "fdisk /mbr" to restore a Windows boot-able MBR.
3. The RH7 boot floppy gets as far as loading the ncr53c8xx SCSI driver,
then hangs right after "ncr53c875-0: on-chip RAM at 0x52100000" message.
4. I can boot from the CD in rescue mode, and am able to mount the root
volume /dev/sda2, but I can't get the system to boot the root volume (linux
root=/dev/sda2). No error, it just doesn't mount.
Here's my hardware configuration. The OS is RH7.0 (Guiness) from CheapBytes:
Compaq AP400
530 Mhz Pentium III processor, 128MB RAM
Compaq CD-ROM CR-589
Compaq DDRS-34560W 4.3GB disk drive
Generic NEC floppy
Matrox Millennium G200 AGP display adapter
Symbios Logic 875XS|D, 2280x PCI SCSI Adapter; 53C875, 53876 Device
Intel 82371AB/EB PCI Bus Master IDE controller
Sportster 56k Data Fax modem
ViewSonic PS790 monitor
PS/2 compatible mouse
Compaq Fast Ethernet NIC NC3121
Intel 82371AB/EB PCI to USB Universal Host controller
ES1869 sound controller (WDM)
I spent a lot of time trying to resolve this without success. Any help with
this problem would be greatly appreciated. Please direct replies to
[EMAIL PROTECTED] Thanks.

The unmodified CueCat prefixes its output with the <Alt>F10 character.
Perhaps your modification does not eliminate this prefix, and it has
some function in the text editor.
By default in Gnome/Enlightenment at least, <Alt>F10 causes a switch to
a different virtual screen.

KLyx is a good choice - stick with it.

hi
here's a simple script to help me identify all the files with
size=0bytes in the current directory:
for file in `ls -1`;
do
if [ ! -s $file ];
then
ls -l $file;
fi
done
this script fails for filenames that contain multiple words, eg. a
filename like "my file.txt" or my\ file.txt.
how can i fix this?

What are the errors you are getting?
Did you isntall all dependcies as mentioned in the article?
Please post the errors so we can tackle the problem together.

If "make" fails, all succeeding commands are bound to fail as well.

That's a source-rpm, but you build a normal rpm from this one.
Oh, and here's a normal rpm:

cdrecord does work with ide/atapi drives. i use a HP-8100 and it works just
fine. however, what you need to do is enable scsi emulation support in your
kernel in order to write CD's. the rest of the time, the normal ide driver
works just fine. check the CD-Writing HOWTO for instructions on writing CD's.
it's very useful.
just another tip, if u compile both scsi emulation support AND ide support
into your kernel, the ide driver takes precedence. i compile both as modules.
by default, the ide driver gets loaded, and when i need to write CD's, i
unload the ide driver and enable scsi emulation instead.
once this is done, do a "cdrecord -scanbus" and your drive will show up.

What exactly is the -t switch good for anyway?
I use the command
shutdown -r +2 now=20
and as far as I can tell its no different than
shutdown -r -t2 +2 now
I haven't played much with the shutdown command until recently so I am
still learning its proper use.

It is an internal timer which tells shutdown to wait n seconds between
killing programs and changing run levels. It gives the programs time to
shut down, if they need the time. If they do not, this will do nothing.
]I use the command
]shutdown -r +2 now
Which makes not sense. th e +2 says, wait two minutes befor shutting
down. The now means wait 0 minutes befor shutting down (now is an alias
for +0). Read the shutdown man page.
man shutdown
