Well, I could I suppose, but it'd be an absolutely enormous GIF file! I'm using some animated GIFs, including one of IBM's 12x17 nanometre 3-input sorter based on cascading CO molecules. Vik :v)
Re: Animations in OpenOffice presentations
I had a lok at the help file for the presentation package in staroffice. it refers to inserting a video by Insert|Object|Video, but mine doesn't have that option. Perhaps its some sort of compile-in option that the binary download doesn't have??

iptables
Hi CLUG, I added these iptables rules to my server/gateway but it makes traffic server go VERY slow eg. mail, POP3, SSH. When I removed them it went ok. The idea of the following rules is to allow incoming SMTP and HTTP server tarffic but block every other incoming connection. iptables -A INPUT -s 0/0 -p icmp -i eth0 -j DROP iptables -A INPUT -s 0/0 -i eth0 -p tcp --dport 80 -j ACCEPT iptables -A INPUT -s 0/0 -i eth0 -p tcp --dport 25 -j ACCEPT iptables -A INPUT -s 0/0 -i eth0 -p tcp -j DROP iptables -A INPUT -s 0/0 -i eth0 -p ! tcp -j DROP Please help. Thanks, Paul

In case you didnt know, ICMP is the Internet Control Message Protocol. Dropping it, is like cutting the legs off of a sheep dog. pretty much makes it useless. ICMP is a LOT more than ping.

The idea of the following rules is to allow incoming SMTP and HTTP server tarffic but block every other incoming connection. iptables -A INPUT -s 0/0 -p icmp -i eth0 -j DROP Firstly, you don't want to drop all ICMP. This will break Path MTU Discovery, among other things. Path MTU is used by TCP to work out how large a packet it can send over the entire length of the connection without sending one larger than the MTU of a single link. iptables -A INPUT -s 0/0 -i eth0 -p tcp --dport 80 -j ACCEPT iptables -A INPUT -s 0/0 -i eth0 -p tcp --dport 25 -j ACCEPT iptables -A INPUT -s 0/0 -i eth0 -p tcp -j DROP iptables -A INPUT -s 0/0 -i eth0 -p ! tcp -j DROP Since you're running iptables, you can use the statefull inspection instead of the old semantics on handling existing connections, so try the following instead: # Accept all incoming packets which are for (a) established connections # which we either initiated outwards, or were successfully initiated # inwards, (b) related packets to such connections (eg, ICMP for Path MTU # Discovery, ICMP for failed connection attempts, etc..) iptables -A INPUT -m state --state ESTABLISHED,RELATED -i eth0 -j ACCEPT # New connections should be passed thru the services chain iptables -A INPUT -m state --state NEW -i eth0 -j services # Everything else should be logged and dropped iptables -A INPUT -i eth0 -j logdrop # Sevices chain: what services do we accept connections for to this box iptables -A services -p tcp --dport 80 -j ACCEPT iptables -A services -p tcp --dport 25 -j ACCEPT # Log chain: Log the packet, then drop it iptables -A logdrop -j LOG --log-level warn --log-prefix=[DROP] iptables -A logdrop -j DROP Now, if you want to allow another serivce you can just add it to the services chain, and all will function. This will work equally well on UDP as it does TCP, with 2.4 you don't have to just open up all your emperhical ports for UDP. So, if you wanted to add a DNS server to the box, you could just do: iptables -A servcices -p udp --dport 53 -j ACCEPT And you're done. - -- I know of no technological device at this time that would [prevent piracy] and if it did exist, it would only be a matter of days before the [..] manufacturers would have an override piece of equipment on their machine and you would start from ground zero again. -- Jack Valenti, President of the MPAA (1982) -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Made with pgp4pine 1.75-6 iD8DBQE9xEnVT21+qRy4P+QRAg1OAJ0U+4OfFESdfTcXJ8SN8yutW6sVNgCfQeX5 dEHZSyY3z2vevPYQYY6JAu4= =o+Z/ -END PGP SIGNATURE-
Re: iptables
Hi-ho, As per Michaels reply... Dropping all ICMP can cause problems, and certainly you should accept some ICMP to be polite.. If you're worried about ping floods, and other ICMP nasties.. Here's a bit from one of my firewall scripts that may help... Not sure if this is original or borrowed from somewhere. # ICMP jump point Put this somewhere in your mail firewall script... iptables -N my_icmp# my ICMP rules. iptables -A INPUT -p icmp -j my_icmp iptables -A OUTPUT -p icmp -j my_icmp iptables -A FORWARD -p icmp -j my_icmp # ICMP Traffic, put this bit after the end of everything... echo ICMP setup. iptables -A my_icmp -p icmp --icmp-type 0 -j ACCEPT iptables -A my_icmp -p icmp --icmp-type 8 -j ACCEPT iptables -A my_icmp -p icmp --icmp-type 3 -j ACCEPT iptables -A my_icmp -p icmp --icmp-type 30 -j ACCEPT iptables -A my_icmp -p icmp --icmp-type 11 -j ACCEPT iptables -A my_icmp -p icmp -m limit --limit 30/minute -j LOG --log-prefix Firewall: ICMP iptables -A my_icmp -j DROP This allows some ICMP through (Type 0,8,3,30,11 see below...) but only 30 packets a minute, so ping flooding wont be an issue.. In terms of the big slowdown, type 3 and 11 can cause that problem... The other thing is that your egress filtering (OUTPUT chain stuff) might be effecting it, are you running any rules on OUTPUT... You should be if you're running a live box, to prevent a breach of your machine creating a honeypot. ICMP types for the curious: You can see there are a few options... 0 Echo Reply 3 Destination Unreachable 4 Source Quench 5 Redirect 6 Alternate Host Address 8 Echo 9 Router Advertisement 10 Router Solicitation 11 Time Exceeded 12 Parameter Problem 13 Timestamp 14 Timestamp Reply 15 Information Request 16 Information Reply 17 Address Mask Request 18 Address Mask Reply 30 Traceroute 31 Datagram Conversion Error 32 Mobile Host Redirect 33 IPv6 Where-Are-You 34 IPv6 I-Am-Here 35 Mobile Registration Request 36 Mobile Registration Reply 37 Domain Name Request 38 Domain Name Reply 39 SKIP 40 Photuris - Original Message - From: Hi CLUG, I added these iptables rules to my server/gateway but it makes traffic server go VERY slow eg. mail, POP3, SSH.

Re: internet cafe software
My suggestion would be Linux Terminal Server Project (www.ltsp.org), I've installed it on Debian a few times and it works rather well. The contrib page includes a billing system for internet cafe's as well as a kiosk reset script (no experience with either) Docs on the billing system can be found here: http://www.ltsp.org/contrib/ltsp_phpSiCafe-install.html Sascha On Fri, 2002-11-01 at 15:04, Tim Wright wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 My parents want to set up a couple of computers in their cafe for internet use.
