Re: [SLUG] Sound plays sloowwwllly on ESS1888
If you can look in the source tree for your kernel, under Documentation/sound/ there might be some more details. It probably depends a bit on what kernel version you are using, but for example in 2.4.3 you can find info about extra module parameters for ESS cards including ESS1888 I find this area to be a great source of info. - Josh -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

Re: [SLUG] Studying Programming
What I've missed out on learning C and gtk+ at home is how to pronounce = and == (in my head while reading code). If you see int x = 1; would you say `assign the value of 1 to the integer x' or`int x assignment 1' ? or some such? It seems quite sensible to pronounce == as `equals'. ?

[SLUG] iptables logging
Hi
I run Debian Sid and have recently thought to tighten security on my
single dialup box. I went through commenting out various unneeded
services in inetd and compiled a 2.4.3 kernel with all the netfilter
stuff as modules.
I put 'Rusty's Really Quick Guide To Packet Filtering' of his Linux
2.4 Packet Filtering HOWTO into a script and added some logging stuff
just to see in syslog that packets are coming through. When I'm
satisfied that the script works OK I'll remove all logging rules but
the 'packets dropped' one.
My question is this. Do all of the packets go onto the next rule after
the first LOG rule? That would make sense but the HOWTO was for me a
bit ambiguous. ie. It says basically that each rule specifies a set
of conditions and what to do if a packet meets them. So, if the
packet meets the conditions for the DROP rule; then the packet is
dropped. It doesn't go onto the next rule. But in this case,
logging, it really only makes sense if the packet does go onto the
next rule.
So, can anyone confirm this?
I thought I would put the script in the /etc/ppp/ip-up.d directory so
that when I dialed into my ISP (via pon) the packet filtering would
start.
I also created a script, packet-filter-down, to basically flush the
chains and remove the modules when I 'poff'; this script will go in
/etc/ppp/ip-down.d.
Are there any better ways? Anything wrong with the above?
Here are the scripts:
packet-filter
#!/bin/sh
# Insert connection-tracking modules (not needed if built into kernel).
/sbin/insmod ip_conntrack
/sbin/insmod ip_conntrack_ftp
# Create chain which blocks new connections, except if coming from inside.
/sbin/iptables -N block
/sbin/iptables -A block -m limit --limit 3/minute --limit-burst 3 -j LOG --log-level
DEBUG --log-prefix $0:
/sbin/iptables -A block -m state --state ESTABLISHED,RELATED -j ACCEPT
/sbin/iptables -A block -m limit --limit 3/minute --limit-burst 3 -j LOG --log-level
DEBUG --log-prefix $0: check
/sbin/iptables -A block -m state --state NEW -i ! ppp0 -j ACCEPT
#/sbin/iptables -A block -m limit --limit 3/minute --limit-burst 3 -j LOG --log-level
DEBUG --log-prefix packet DROPped:
/sbin/iptables -A block -j DROP
# Jump to that chain from INPUT and FORWARD chains.
/sbin/iptables -A INPUT -j block
/sbin/iptables -A FORWARD -j block
exit
packet-filter-down
#!/bin/sh
# Flush the chains; remove the block chain.
/sbin/iptables -F block
/sbin/iptables -F INPUT
/sbin/iptables -F FORWARD
/sbin/iptables -X block
# Remove the iptable modules.
# This removes modules beginning with ip; that could
# be dangerous. Perhaps I should explicitly list them?
for mod in $(/sbin/lsmod | awk -- '/^ip*/ {print $1}'); do
/sbin/rmmod $mod;
done
exit

'Structure and Interpretation of Computer Programs', a highly regarded computer science textbook, doesn't introduce assignment until page 218, chapter three.
