unpacking Dell’s iDRAC schtuff
I hadn’t look at Dell’s iDRAC stuff in forever… and it appeared they’d changed some of the formatting of the iDRAC updates/etc. since then. I didn’t see anything out there, so here’s what I used. First, grab an update – for instance, at – https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=wn31m – I grabbed “iDRAC-with-Lifecycle-Controller_Firmware_WN31M_LN64_7.20.30.50_A00.BIN” On the windows EXE file at…

stupid docker tricks #239192
1) Limit max processes on container; unfortunately docker seems intent on me not doing docker stupid tricks, so this is actually a bit of a pain on some systems… but if you figure out/etc/security/limits.conf, or can use prlimit (or write your own; use RLIMIT_NPROC instead of RLIMIT_NOFILE), you can do “prlimit –pid 666 –nproc=3:3” to limit the processes…

shotgun scanning
UDP scanning has always been slow. Slower than slow, slower than molasses, really fucking slow. So when I started being interested in scanning for IPMI out in the wild, which runs on UDP 623, I first fired up trusty ol’ nmap… but bless it’s heart, it’s a cautious, robust scanner that is outrun by crippled…

one packet auditing
Not all packets are equal. If you send a single UDP packet to port 623 that contains an “Get Channel Authentication Capabilities” (see secion 22.13 of the IPMI v2 spec), you’ll get back a packet that has some interesting features. You can get this by parsing the output of “ipmitool -v -v -H 10.0.0.1 -U…
