After mounting a bunch of filesystems I thought I’d just whip up a little shell script to help me out when working with jffs2 images, mtd, and linux (only tested on centos 6.) I won’t go over how to get kernel support and all that crap – there are many guides, and while many won’t work eventually something will for you too ;( This one is fairly simple to […]
Since I didn’t find it anywhere else… Avocent, who makes a heck of a lot of BMCs, and at times (like with Dell’s iDRAC, at least version 6) keeps encrypted passwords in (well, quite possible/probable OEM dependent) “/flash/data0/etc/avctpasswd” (don’t be fooled by the /etc/passwd file) using SHA1 hashed passwords converted into Base64. I surmise this file is used to protect the real passwords that are stored in clear text […]
Looking at a file (manuf_sign_cert.sh): # This script is run on every iDRAC at manufacturing time. # to create a certificate with a derived CN using the # service tag so it can be authenticated by a provisioning server # for zero touch deployment. # # Files used: # 1) d_h_ssl_manuf.cnf # 2) ROOTCAPK.PEM (loaded by mdiags via dynamic partition) […] ENCRYPTED_CA_PRIV_KEY=”/tmp/MFGDRV/ROOTCAPK.PEM” […] #decrypt the signing key if !

Or, perhaps, working with a really minimal system… saw two posts that were pretty handy – basically how to reconstruct binaries with the shell alone (no cheats like mv or an editor or anything…); reconstruction by force: http://fakeguido.blogspot.com/2010/08/rescuing-hosed-system-using-only-bash.html And: http://www.eusebeia.dyndns.org/bashcp Some nice little functions here building on the above: http://www.h-i-r.net/2009/08/cratered-your-linux-box-here-are-some.html
Lost in Translation is really a fabulous movie – if you’ve travelled a lot while being in monogamous relationships (and probably a guy, or at least of a certain mindset), and in particular tokyo or somewhere that is really alien. The sense of awe and aloneness… and the grandeur of tokyo, which I’m already in love with… Sofia just nailed that one. I don’t know what I’d think if […]
