Current status

  • Last updated: 2016-05-30
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Slogin symlink to ssh exists for years for compatibility with ancient systems and was recently removed from upstream openssh package. There is no need to hold this symlink. Possible dependent packages need update just in the words of substitution s/slogin/ssh/g.

Sshd-keygen executable is also years obsolete copy from init scripts and does not make use of systemd features. In F24 new sshd-keygen is used, but for compatibility issues (anaconda) the old sshd-keygen is still there. Applications/services that needs to make sure that ssh host keys are available, should depend on sshd-keygen.target instead of running sshd-keygen executable.

Benefit to Fedora

Do not diverge from upstream and lower maintenance costs in slogin case.

Using systemd instantiated service adds more flexibility in control of what keys are generated.

Scope

  • Proposal owners:

Remove the symlink from spec file (revert commit) and remove sshd-keygen from dist-git script (revert sshd-keygen commit).

Package maintainers (anaconda) depending on these files in system should follow recommendation how to work without them.

How To Test

Check for existence of files /usr/bin/slogin and /usr/sbin/sshd-keygen on your system. They should not be there.

1. Open terminal (if not open yet)

2. Make sure you have installed openssh-clients and openssh-server packages: 

rpm -q openssh-clients openssh-server
openssh-clients-7.*p2-*.fc25.x86_64
openssh-server-7.*p2-*.fc25.x86_64

3. Check if you have the files in your system: 

ls /usr/bin/slogin /usr/sbin/sshd-keygen
ls: cannot access /usr/bin/slogin: No such file or directory
ls: cannot access /usr/sbin/sshd-keygen: No such file or directory

4. The files are not there
