ssh to qemu, with the Hurd

Follow-up to Hurd on qemu from Nothing to see here

Using sshd on the Hurd makes things relatively painless – with the normal qemu interface, you can’t (as far as I know) copy and paste to the console. However, connecting over the network gets you all kinds of benefits, such as the right keyboard layout locally.

The Hurd-specific bit is getting sshd to work – first you need to get /dev/random and /dev/urandom working (because they don’t by default – you may start laughing now). The Hurd Installation Guide from UWHUG still works.

# cd && mkdir tmp && cd tmp
# wget http://kilobug.free.fr/hurd/random-64.tar.gz
# tar xvfz random-64.tar.gz
# cp random/random /hurd/

# settrans -c /dev/random /hurd/random \ 
           --seed-file /var/run/random-seed --secure
# settrans -c /dev/urandom /hurd/random \ 
           --seed-file /var/run/urandom-seed --fast
# chmod 0644 /dev/random /dev/urandom
# apt-get install openssh-client openssh-server

Disable UsePrivilegeSeparation in /etc/ssh/sshd_config as well – I didn’t check, but I’m fairly sure that bug still exists. You’ll want to allow root logins, because su doesn’t work. (I forget whether that bug has a workaround.)

Then to actually connect to qemu, I’m using a command like this:

qemu -hda hurd.img -m 256 -redir tcp:2222::22

Then:

ssh -p 2222 user@localhost

Easy.
