search for: oom_adjust_setup

Currently, on linux sshd attempts to remove itself from the influence of oom-killer by modifying the oom_adj parameter for itself in proc to -17. This is controlled via two functions; oom_adjust_setup() and oom_adjust_restore(). Setup saves the old score (typically zero on initialization) and sets sshd to -17 whilst oom_adjust_restore places the saved value from initialization back into the running sshd process. The principle here being that whilst we want the main sshd listener process never...

Thanks Ben. i am checking in linux. I do have this command working: ssh localhost -o password=abc123 SSH started with password Could not create directory '/root/.ssh'.

But is it possible to show some pointers for my

Hi, OpenSSH 8.0p1 is almost ready for release, so we would appreciate testing on as many platforms and systems as possible. Snapshot releases for portable OpenSSH are available from http://www.mindrot.org/openssh_snap/ The OpenBSD version is available in CVS HEAD: http://www.openbsd.org/anoncvs.html Portable OpenSSH is also available via git using the instructions at
