TP-Link TL-WR743ND is the PoE brother of the common TL-WR741ND wireless router which is supported flawlessly by openwrt. Since I’ve got one WR743ND, I wanted to convert it into a useful OpenWRT router but I figured out that, unfortunately, the WR743ND is not supported by OpenWRT (at least officially). Given the similarity to the supported WR741ND, I’ve decided to hack it a bit to get it work with OpenWRT.
On CentOS 5 (and RedHat EL as well), you can encounter the following behaviour when configuring an nrpe plugin with sudo:
[andrea@feyd ~]$ /usr/lib/nagios/plugins/check_nrpe -H 184.108.40.206 -c check_md_raid
NRPE: Unable to read output
On my Fedora 8 system with Amarok I was trying to fill an mp3′s tag header using MusicBrainz, getting the following error:
Tunepimp (MusicBrainz tagging library) returned the following error: "Fingerprinting of .mp3 files is not supported."
To make it work, just
yum install libtunepimp-extras-nonfree
Recently I’ve been in an awkward situation with ssh and X11 forwarding, where ssh using the classic -Y (or -X) switch wasn’t working (DISPLAY was not set):
[andrea@duncan ~]$ ssh -Y root@thufir
Last login: Sat Apr 12 23:30:09 2008 from ***
[root@thufir ~]# echo $DISPLAY
If you are experiencing the same and your sshd_config looks fine (which means TCP and X11 forwarding is already enabled) then the answer is missing xauth!
yum install xauth will do the trick
