Tags: cli, security, ssh, tips

I use an SSH gateway for work (one that requires two-factor authentication: an RSA SecureID PIN and an AES-encrypted Kerberos password). Problem is, since the gateway servers are clustered and change often, I sometimes get the following:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE [...]

(Another “piecemeal” post. Yes, I know: I should write more often.)
I cycle through one-off passwords (of varying lengths). To generate these, I use the following shell script:

#!/bin/bash
 
usage() {
echo "Usage: `basename $0` [length]"

[ $# -eq 0 ] && len=8 || len=$1
 
strings /dev/urandom | grep -o [...]

I’ve been meaning to fold in [...]

Fix for Picasa 3 Linux login problem

Picasa 3 for Linux has this niggling* problem: you can’t log on to Picasa Web. [...]
