Good question. I have cloned the git version of OpenSSH for disco- proposed. When I compile this version of the code, the privilege separation directory is defined as "/var/empty" which would solve the problem. However, the installed version 18.04.2 LTS (bionic), has it defined as /run/sshd. The man pages for disco-proposed indicate that the privilege separation directory is at /run/sshd. So, which git repository should I use to get the Ubuntu 18.04.2 (LTS) / OpenSSH 7.6p1 should I use? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1832110 Title: Resource Sharing with multiple sshd services Status in openssh package in Ubuntu: Won't Fix Bug description: Ubuntu: 18.04.2 LTS OpenSSH: 7.6p1 I am having a problem starting multiple sshd processes. The default location of the sshd privilege separation directory is hard-coded to /run/sshd (see man page). If I want to have 2 sshd services using systemd, I need to write 2 service files, let's call them sshd_wan.service ans sshd_lan.service. Both of these services need to have their own "RuntimeDirectory=sshd_wan" and "RuntimeDirectory=sshd_lan". If you do not have separate RuntimeDirectory definitions for the 2 services, then when one service is killed/faults/restarts/stops/etc. the systemd (or init) process deletes the RuntimeDirectory and causes the other service to crash since a RuntimeDirectory does not exist. The problem is the hard-coding of the sshd Privilege Separation Directory. We need to modify the OpenBSD/OpenSSH sshd code to provision command line assignment of the privilege separation directory. I have attempted to contact the OpenSSH team (i.e. OpenSSH.com) and they say it is a Ubuntu problem. I reported this in Ubuntu bug #1831765 and Ubuntu (e.g. Paride Legovini, June 6, 2019 @ 2:55AM PDT) rejected it because I described the problem using the init.d example. I know how to modify the sshd.c file in OpenSSH 7.6p1, the problem is getting Ubuntu and OpenSSH to admit there is a problem and it needs to be fixed. The problem is still there regardless if you are using Upstart (i.e. init.d) or systemd.
