printer maintenance

My Epson CX6400 hasn't been printing properly for a while. This weekend I got around to taking it apart to see what was up. The usual story with inkjets is that the waste ink tubes get clogged. I was unable to find a service manual for free online, so I just dived in with screwdriver… Continue reading printer maintenance

fighting the code

Why doesn’t automake/autoconf properly recognise the way to use Flex/Bison with C++ scanner/parser generation? I use a .ll file and it thinks the output is going to be a .c instead of a .cc. Likewise I use a .yy file and it screws up the includes in my bison output because it decides to go… Continue reading fighting the code

Castlevania: SOTN on XBL Arcade!

Run, don’t walk. This game is one of the more brilliant things you’ll play in your life. Actually, I don’t know if it’s quite out yet. I have it on the dev network. But soon if not now. Drool in anticipation.

port triggering with OpenWRT works!

I finally got around to compiling the ipt_TRIGGER kernel module with some logging in there, so I could tell where I was going wrong with my iptables commands. The correct iptables commands are: #iptables -t nat -A prerouting_wan -p tcp –dport 6881:6889 -j TRIGGER –trigger-type dnat #iptables -A forwarding_wan -p tcp –dport 6881:6889 -j TRIGGER… Continue reading port triggering with OpenWRT works!

should I tell them?

I used one of my local open wireless access points to download some stuff on my laptop. Actually, just enough to get the wireless card working with WPA. Should I tell my neighbours to secure their AP?

wireless (in)security

It's amazing what you can glean just from listening to the ether. Armed with an old laptop, wireless card, Kismet, and quarter of an hour, I can tell you the following about my neighbourhood: There are 3 open wireless access points, 4 WEP-protected ones, and 5 or 6 WPA protected ones. One open point is… Continue reading wireless (in)security

port triggering iptables config

I think the relevant iptables commands for port triggering with Bittorrent are: #iptables -t nat -A prerouting_wan -p tcp –dport 6881:6889 -j TRIGGER –trigger-type dnat –trigger-proto tcp –trigger-match 6881 –trigger-relate 6881-6889 This tells the router to do NAT on the packets arriving on the WAN TCP ports 6881 through 6889 as allowed by the trigger… Continue reading port triggering iptables config

kernel hacking

Now that I’ve got my new router set up (it’s working fine btw) I decided to dig a bit deeper into the firmware possibilities. Warning: this post is mostly martian, and it’s long. The first thing I wanted to investigate was the possibility of port triggering. Port triggering is an alternative to static port forwarding:… Continue reading kernel hacking

new router

Lately my SMC2804WBR has started to play up a bit (arbitrarily causing loss of connectivity), so this weekend I finally got around to replacing it. Mrs Elbeno was complaining of having to power cycle it 2 or 3 times a day. Where wireless broadband routers are concerned, experience has taught me that once you get… Continue reading new router

Mini-Elbeno can read!

Lately mini-Elbeno has started to read words. No, really! Last week I printed out some flash cards and he can read about a dozen of them: nose, ears, dog, clap, wave, arms up, arms down, ball, book, and more I can't remember now. Although he can't say many of them intelligibly yet (only “buh” for… Continue reading Mini-Elbeno can read!
