2017-04-26 Wieder Problem mit Backup ambra

Problem: seit 6. April 2017 geht der ambra backup nicht mehr, Ursache noch unklar. Ursache SSHD config kaputt. Cygwin shell als administrator öffnen:

ssh-host-config

*** Info: Generating missing SSH host keys
*** Query: Overwrite existing /etc/ssh_config file? (yes/no) yes
*** Info: Creating default /etc/ssh_config file
*** Query: Overwrite existing /etc/sshd_config file? (yes/no) yes
*** Info: Creating default /etc/sshd_config file
*** Info: StrictModes is set to 'yes' by default.
*** Info: This is the recommended setting, but it requires that the POSIX
*** Info: permissions of the user's home directory, the user's .ssh
*** Info: directory, and the user's ssh key files are tight so that
*** Info: only the user has write permissions.
*** Info: On the other hand, StrictModes don't work well with default
*** Info: Windows permissions of a home directory mounted with the
*** Info: 'noacl' option, and they don't work at all if the home
*** Info: directory is on a FAT or FAT32 partition.
*** Query: Should StrictModes be used? (yes/no) no
*** Info: Note that creating a new user requires that the current account have

*** Query: new local account 'sshd'? (yes/no) yes
*** Info: Updating /etc/sshd_config file
*** Info: Sshd service is already installed.
*** Info: Host configuration finished. Have fun!

Danach ging

net start sshd

2016-09-09 sshd login problem auf ambra

Problem: seit 4. August 2016 geht der ambra backup nicht mehr, weil ssh von hawaii nicht mehr funktioniert.

Analyse: Hawaii (der Rechner auf dem BackupPC aka ad-backuppc2 läuft) war ursprünglich im 132.230.152.* Netz (und im 10.4.152.*), wurde dann Anfang August zusätzlich ins 10.8.152.* eingetragen und Routing ging ab dann direkt über 10.8.152.* (und nicht mehr über 132.230.152.* wie vorher).

Lösung: ambra -> Windows Firewall -> Advanced Settings -> Inbound Rules -> sshd -> Properties -> Scope -> Remote IP addresses -> Add: 10.8.152.58 (das ist hawaii-p.informatik.privat) ... bei der Gelegenheit 132.230.152.0/24 gelöscht (das sind unsere Server: stromboli, etna, alicudi, elba, ...)
