Content overview

This page is about technical issues for anyone producing packages for Mandriva. Organisational issues are described in Maintainer Howto.

Shell aliases

You can set up aliases to make life easier for yourself. Some examples are:

alias tailue="tail -f /var/log/ue/ue.$(date +%Y%m).log"
alias ue="sudo /usr/local/bin/ue"
alias findrpm='find $(rpm --eval %_rpmdir) $(rpm --eval %_srcrpmdir) -mtime -1 -type f'
alias ftpcontrib="sudo /usr/local/bin/ftpcontrib $(findrpm)"
alias ftpcooker="sudo /usr/local/bin/ftpcooker $(findrpm)"
alias rpmlint='rpmlint `findrpm`'

SSH configuration

If you want to directly use ssh on nX computer.

/home/misc $ ssh n1 hostname ; hostname 
n1.mandriva.com
crovax

First, you need to use an ssh key. Use:

ssh-keygen -t dsa

and copy the content of id_dsa.pub to the file .ssh/authorized_keys. Please use a long passphrase (to protect the key is very important for security reasons).

NOTE: You need to be sure of the permissions of your private key ( ~/.ssh/id_dsa on your computer must be "rw" for the owner only), of the permissions of your .ssh folder (e.g. ~/.ssh on your computer must be "rwx" for the owner only). Same thing for the authorized_keys on the server. Therefore when you edit those files remember to change their permission; for example for authorized_keys you can use the command chmod 600 ~/.ssh/authorized_keys.

When all this is ok, you will be able to use an agent with the default Mandriva Linux installation.

Each time you log on to your workstation, type ssh-add in a console, your passphrase, and you will be able to log into kenobi without password. The second thing to do is to enable ssh agent forwarding on kenobi. For this, just add this in your ~/.ssh/config:

Host kenobi.mandriva.com
        ForwardAgent yes

Now, you can use ssh n1 without password on kenobi. To do so, type:

ssh kenobi.mandriva.com -t ssh n1

But this is not enough. The last step is to add this in your config files:

Host n1 n2 n3 n4 n5
    ForwardAgent yes
    ProxyCommand ssh -qax kenobi.mandriva.com /usr/bin/nc %h %p

Then ssh n1 will take you to n1, using the subversion server through ssh will work, like scp or rsync.

SSH config

Add the following to your ssh config if you use ssh-agent, makes life easier:

# Mandriva
Host n1 n2 n3 n4 n5 deborah seggie
  ForwardAgent yes
  ProxyCommand ssh -qax kenobi.mandriva.com /usr/bin/nc %h %p
  Host kenobi
  Hostname kenobi.mandriva.com

# Mandriva chroots
Host chroot100
  Hostname n1.mandriva.com

  ProxyCommand ssh -qax n1 /usr/bin/nc -w 120 %h %p
