A small dictionary attack on sshd (in my case 260 tries over 12 minutes) are able to produce auth.log.0:Aug 3 05:30:35 dirk sshd[1825]: fatal: Couldn't obtain random bytes (error 604389476) and the sshd dies (followed by apache on the first subsequent SSL request and so on). Unfortunately I can't help you in tracing the uml process or trying patches - this is a virtual server at my provider and I don't have any access there. I could try to get the .config file. # uname -a Linux dirk 2.6.26 #1 Wed Jul 30 10:56:10 CEST 2008 i686 GNU/Linux # cat /proc/cpuinfo processor : 0 vendor_id : User Mode Linux model name : UML mode : skas host : Linux seldon-base 2.6.23.17 #2 SMP Sat Jun 21 15:04:22 CEST 2008 i686 bogomips : 4771.02 # cat /proc/sys/kernel/random/entropy_avail 293 After exhausting the entropy with cat /dev/random | od -cx the entropy only slooowly gets up, one byte per several seconds or so with me typing in the ssh console...
