Daily disk array spinup at 7:34

While it may sound like utter nonsense at first, on second thought maybe it really is: cron.standard: please provide configuration facility to avoid given filesystems
Someone should really be thinking more about a serious reminder system.

I've put together an iotop oneliner that logs disk actions with timestamps which pointed me to anacron. Daily mlocate updating was easy to reproduce and fine tune: simply add your HDD mount points to tho PRUNEPATHS variable of /etc/updatedb.conf.

On the other hand, it took a few more attempts and many days in total to track down what causes the HDDs to still start up. When trying to further examine the issue by hand, /etc/cron.daily/standard didn't start them up on first look, perhaps because of caching. However, today after randomly testing things again, it finally did, which took me to adding CHECK_LOSTFOUND=no to /etc/default/cron.

It's a pity though, that I'll have to use an alarm clock from now on.

Tftp secret of TL-WR740N uncovered

I've found out that even this particular entry level router supports anti-bricking, so there's no need for soldering, unless of course you are modding. The method I used is the following: Set up a tftp server  on your PC and verify if it works correctly (configuration, permissions, firewalls, etc.) Rename your target firmware to wr740v4_tp_recovery.bin and copy it to your base folder (by default /tftpboot). I tested with openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin r43602. Set up the following static IP for your PC: 192.168.0.66 /255.255.255.0. If you're not sure about the firmware name on a different model, start a packet sniffer on your PC ( tcpdump -i eth0 -n -l ) and look for the name in the RRQ message. Preferably disconnect WAN from the router Connect the PC to a LAN port Power off the router Press and hold the reset button Power on the router After the leftmost (power) LED and the rightmost (padlock) LED turn on alone in a few seconds, release

Hidden TFTP of TP-Link routers

I did some more investigation after the positive results with the TL-WR740Nv4  (click the link to get introduced to the way of recovery). Most users report that devices and firmware updates released after a point in time usually have this mode enabled. If a firmware update is available from the vendor for your device, it's a good idea to apply that update before installing OpenWRT or dd-wrt UNLESS you own something for which upgrading will ensure incompatible with OpenWrt, like a TL-WR730N , and possible some other models (please report). Note that some old models have newer updates in different languages, those may also be worth a try ( TODO : compatibility?). Also remember that later on, tftp recovery will need a type of firmware image without a boot loader, so strip it with dd if yours has it ( grep U-Boot , or check the filename). Positive reported claims so far (personal results highlighted): TL-WDR4300 router 192.168.0.86 server 192.168.0.66 query wdr4300v1_tp_recovery.b
