Redelivery of frozen messages in EximHere is how I did it: exim -M `exim -bpu | grep frozen | awk ‘{ print $3 }’ | xargs`. A nicer shortcut form I discovered afterwards is exim -M `runq | grep frozen | awk ‘{ print $3 }’ | xargs`. |

An IPv6 at home experimentI don't know how many people tried this before but here is my account on using IPv6 at home. the affair consumed between a Linux machine acting as router and a Mac OS laptop acting as client. First thing I noticed is that Mac OS is configuring the interface by picking an address from the fe80::/10 range, the link-local prefix. Another obvious thing after a little tcpdump-ing is that Mac OS is continuously searching for routers using some ICMP6 datagrams. One program that knows how to send router advertisements is radvd. The packet is available in Debian so installing it was a piece of cake. For a moment I though that I will not need to pick a network address for my network but radvd didn't want to work without one so I picked a /64 in 2001:db8::/32 but probably a more correct prefix is fc00::/7. Wikipedia explains this better. So at this point I reached the point in which I could ping the Linux box. The second step was to configure the DNS. My first attempt was to used Dibbler but Mac OS doesn't have support for DHCPv6. :| In fact, the only way to configure the DNS for IPv6 in Mac OS is to do it manual. I usually use dnscache from djbdns but because it doesn't know IPv6 I had to search for an alternative. The solution I chose is proxy server called Trick Or Treat Daemon (totd). The packet is already in Debian but I had to do some tricks to get working version I tried from stable. First, the totdconfig configuration program doesn't work if the /etc/totd.conf is missing and second, totd didn't want to start unless /var/run/totd is created. So a 'touch /etc/totd.conf' and 'mkdir /var/run/totd' solved the problem. One last thing is the translation between IPv4 and IPv6. I found two solutions: naptd, an implementation of NAT-PT and ptrtd, an implementation of TRT. None of them are available in the Debian repository but I found a deb for naptd here and one for ptrtd here. I tried the latter and it worked well for me. The only thing I need to edit is the prefix mentioned in /etc/default/ptrtd. And now here are some things that I notice that doesn't work:
You may ask what did work. Web browsing (Safari, Camino, Firefox, Vienna), ssh, ping6. :P |

My Blueberry Nights
This evening I had to chance to see My Blueberry Nights at The Charles. It's a Kar Wai Wong and one special thing about it is the fact that is his first English movie. The second special thing is that fact that cinematography is not done by Christopher Doyle. Going back to the movie, I would say I like it despite quite a big numbers of bad reviews and not so happy viewers. As J. R. Jones from Chicago Reader says, the movie is like "slow-rolling billiard balls". The story is developing slowly and it consists mostly with details than action. I liked that. It gives me the impression of an old man meditation to the life around him. |
