Ok thanks, simply needs
sudo touch fastboot
as soon as I begin devellopping...
And if the computer crashes during devellopment, I will try to run
/sbin/shutdown -rF now
as soon as I finish.
Thanks,
Simon

Hi, I face the same situation (changing the mouse from serial to
PS2) and did the same thing (ln -s /dev/psaux /dev/mouse).
But after that my XF86Setup won't start any more (can't remember the
errors, didn't make sense to me... some communication was broken...)
This is under Debian. Previously /dev/mouse was pointing to /dev/ttyS0.
I went further to change the mouse setting in the
/etc/X11/XF86Config to the values from my other RedHat62 box. And it
still didn't work.
Took me over 4 hours trying to fix the damn mouse. Did get the gpm
working though... Any step by step recommendation or check points
(where are the mouse related files under debian)? thanks a lot!
Beside, Debian modprobe complains that my /etc/modules.conf is newer
than some cached value, how can I fix that?
thanks

I have read various how-to's, help documents and emails from newsgroups
on installing Win2k and Linux on one PC. However I don't get far enough
to set up
LILO to dual boot since following installation of Linux I can't even get
the PC to
boot back into Win2k (installed first). (However I can boot into Linux
using the
boot floppy created during installation of Linux). Each OS is installed
on a 30G IDE drive.Win2k is on the Primary HDD - Linux on the Slave.
LILO has not been written to the MBR. Haven't got the lilo.conf file
handy ... however it appears to
agree with all that is written about it (and I don't think I'm even
getting to the stage
of using LILO). I think I'll be set if I can get Win2k to boot. Anyone
else come across this problem? Any suggestions?
Thanks

I unzipped the source into my root account home directory, (the
README for 2.4.0 explicitly states you should not unpack the source in
the /usr/scr/linux directory, as libraries include some files here and
this action may mess the libraries up). then:
cd linux
make mrproper
make xconfig
(configure kernel)
make dep
make bzImage
then I copy the image to /boot/bzImage
I added an image= entry into my lilo.conf file so I can boot the new
kernel as well as my old kernel (which is located in /boot as well.)
then I run /sbin/lilo
I reboot, choose the new kernel image I just compiled, and I get the
/boot/System.map contains wrong version warning message.
Incidentially, when the APM daemon is being loaded, I get this error:
/lib/modules/2.4.0/module.dep not located
or something similar. I did not choose the module option for any of
the kernel config choices, unless one was m by default and I missed
it, which I don't think is the case.

Power management is working fine. xset dpms N_SECONDS works as advertised:
the monitor is powered off after N_SECONDS elapse. It's just that the
screensaver, as setup within GNOME no longer seems to automatically activate
it. arg, Red Hat, what did you do?

Subject: help with configuring squid server
Date: 28 Apr 2001 23:56:13 GMT
Hi Everyone,
Please help me with this situation:
I have a small home network (network 172.16.1.0/24). This network
has 5 clients with IP addresses: 172.16.1.1-5. The network has
a Linux Gateway with internal IP address 172.16.1.254 and external
IP address 207.172.1.150. The linux gateway is running NAT
(aka masquerading) for internal network to connect to the Internet.
The linux gateway is running Redhat Linux with kernel 2.4.3 and
Netfilter (aka iptables). Everything is working.
Now I like to put a squid (proxy server) onto the network. The IP
address of the squid server is 172.16.1.253. The squid can access
the Internet. How can I configure squid server in such a way that
clients on the internal network, when they access the Internet, has
to go through the squid BUT WITHOUT HAVING TO CONFIGURING
THE WEB BROWSER (Netscape or Internet Explorer). I heard that
this method is called TRANSPARENT PROXYING. What do I need
to modify the rc.firewall script on the Linux Gateway for this to work?
I am running both kernel 2.4.3 on the squid server and the linux
gateway.
Please help.

You can create a perl function in suck and pass some fields (depends
on your nntp server) from the header. Then you filter whatever you
want. Again, the keyword is that this is not a single regex but a
perl function. Yes, you are right that you cannot do this in one
single regex. You can negate, but only characters (or a bunch of chars)
but not strings.
Try something like
($from, $subject, $etc...) = @_;
return 0 if $subject =~ /debian/i;
return 1 if $subject =~ /linux/i;

Yes, the System.map is the kernel's symbol table. You installed
a new kernel and the old symbol table (which was created for a
different kernel) obviously doesn't match. You can ignore the
error, or if it bothers you, then copy the System.map file from
the root of your kernel source after compiling to /boot/System.map.

Where did you get this info? You can certainly run Linux without swap.
The "twice the size of your memory" is just a generic rule which
satisfies most people. But it doesn't have to be at least that.

Subject: ipchains test with nmap and iptables logging
Date: Sun, 29 Apr 2001 04:15:27 GMT
I have two boots, one with a 2.2.18 kernel and ipchains, and
one 2.4.2 kernel and iptables. As it is a stand-alone ppp-only
machine, I made my rules to not allow any syn/ack responses to people
trying to use my services. (At least I think I did)
my ipchains is like this:
/sbin/ipchains -F input
/sbin/ipchains -F output
/sbin/ipchains -A input -i ppp0 -p tcp -d 0/0 auth -y -l -j ACCEPT
#accept auth queries
/sbin/ipchains -A input -i ppp0 -p tcp -d 0/0 :1023 -y -l -j DENY
#deny all other attempts to use services
/sbin/ipchains -A input -i ppp0 -p tcp -d 0/0 31337 -y -l -j DENY
#block and log Back orifice attempts
/sbin/ipchains -A input -i ppp0 -p tcp -d 0/0 12345 -y -l -j DENY
#block and log Netbus attempts
My iptables:
/sbin/iptables -F INPUT
/sbin/iptables -F OUTPUT
/sbin/iptables -A INPUT -i ppp+ -p tcp --dport auth
--syn -j ACCEPT
#accept auth queries
/sbin/iptables -A INPUT -i ppp+ -p tcp --dport :1023
--syn -j DROP
#deny all other attempts to use services
/sbin/iptables -A INPUT -i ppp+ -p tcp --dport 31337
--syn -j DROP
#Back orifice log attempts
/sbin/iptables -A INPUT -i ppp+ -p tcp --dport 12345
--syn -j DROP
#Netbus log attempts
...........................................
OK , my queries:
a) How do I log any attempts to use my services under iptables ?. The
docs were not very helpful . In ipchains it's just the "-l" switch
b) I tried to port-scan myself by dialing up my ISP, getting my IP,
and "nmap"ing myself. But it said all my ports were open. I then tried
to telnet to my_IP port 25, using the same dynamic IP, and managed to
send mail to myself. This under iptables and ipchains rules above.
I then went to www.hackerwacker.com , and they said my
services were closed. (only auth open, which is what I intended). Why
do I get different results from nmapping myself through my ISP, and
letting hackerwacker nmap me ?

If you have access to another linux machine, make a bootfloppy there.
(for RH systems, just run `mkbootdisk <kernel-version>`)
And boot from that using "linux root=/dev/hda3"
(Perhaps try that from the RH CD, leave the rescue keyword?)

/mnt/sysimage/sbin/lilo -C /mnt/sysimage/etc/lilo.conf
But now it will probably complain that /dev/hda doesn't exist.
And other inconsistencies.
The easiest way is by mounting /dev/hda3 at /
This must be done at boottime

The latter I presume.
I cannot be 100% sure that the install completed, but making a bootdisk
during install, usually is the last step. So I suppose the install finished.
