I find iptables to be a bit of a beast… so for posterity (or my own sanity, in case I lost this, I might recover from search engine caches!) this simply forwards a port (A) of a certain protocol from one host (B) to a second port (C) on a 2nd IP (D). Linux only, unless your OS happens to support iptables… no error checking, although it will echo […]

In conjunction with the openssl scripts… a little bit of python code to fire up an ssl server… lots of them out there, this one is mine. #!/usr/bin/env python # # fire up an HTTPS/ssl web server in the PWD (defaults to localhost:8081) # # optional – give a file name to serve up, like "$0 foofile.html" # If you use this option it’ll wait a few seconds and […]

I put a script or two on github; generates a CA and server and client certs, suitable (I hope!) for openvpn and https and all that.

A trivial utility to dump password/account information from a special file found on a SM BMC (see this R7 post about the PSBlock file.) (Later edit – put a new version on github that fixes a bug) #!/usr/bin/env python # usage: $0 file # # (try to) Dump out passwords/accounts from a SM binary file; # usually this is in /conf or /vm on the BMC, and goes by […]
