Re: [gentoo-user] leap second

Is it just left to the local machine to realise it's 1 sec fast adjust over a few hours or does something else alert it to correct things ? If the former, it could create problems for those running experiments; if the latter, does anyone know how it is done ? The last leap second was 1998/9 , before NTP was widely used. http://en.wikipedia.org/wiki/Unix_time http://en.wikipedia.org/wiki/Talk:Unix_time These _might_ help you understand this confusing subject. For me they just gave me a headache. The best I can tell POSIX handling of time-keeping is just broken. In short, don't worry too much about it. If you really want to know what time it is use GPS time (a sane TAI-based system), then convert that to UTC. Jonathan Kollasch pgpJZyLNgRl9H.pgp Description: PGP signature
Re: [gentoo-user] ghosting(?) a drive

Hopefully, I can just boot up from the new drive as if nothing had changed. Can anybody recommend any tool(s) for the job? Gotchas? Does SATA prefer a certain fs? If the new drive has a greater or equal number of blocks than the old you could boot a LiveCD then dd(1) the old device (something like dd if=/dev/hda of=/dev/sda IIRC) onto the new device. You then should be able to boot directly off of the new drive. Or you could create new file systems on the new drive then cp -PRp or rsync the old data to the new drive. In the later case you'd need to reinstall GRUB or LILO. Be sure to not erase the old drive until you're sure the data got copied correctly.

Is my ipv6 address working now? I don't see a clue on how to do testing. Well it should be, but it's not. I can ping (your|their) router, but not your server. You might try a traceroute6 to see where the problem might be. If you still need help try #IPv6 on irc.freenode.net. Or if your ISP provides support for IPv6 talk to them. ~~~ One question important to me but I never understood well. If I have a website only defined on IPv6 address, is this website accessible from major platforms (e.g. Win2k+/modern Linux, IE 6+/Firefox 1+) without any special configuration on the client side? Windows (XP) has IPv6 disabled by default. Users would need to configure it. On Linux if an IPv6 router advertises itself configuration is often automatic. But once users have an IPv6 connection your site should be accessible (assuming you get your connection up). Jonathan Kollasch -- gentoo-user@gentoo.org mailing list

Um, Broadcom + IEEE 802.11 + Free Unix = no support (unless you're running a Linux 2.4 kernel on the MIPS32-el architecture, and then it's a proprietary binary).

With arp -a IP arp -e I can only check the MAC address. Is there a way to other way around. I know ethereal will capture the IP address, but I was wandering if there is any command line tool. Ethereal's CLI counterpart is tcpdump, (you can use tcpdump to make capture files for Ethereal) you could also look in your dhcpd's lease file, or see if it responds to a ping to 224.0.0.1.
