Raw Blame History

Subject: [PATCH] Sshd: revert Sshd module to 1.1.0-compatible, add Sshd_140
In order to keep the default sshd config lens compatible with 1.1.0,
the lens from 1.4.0 has been kept in the Sshd_140 module and is not
loaded by default. Use aug_transform, augtool --transform etc. to use
it instead of Sshd.

+Module: Sshd_140
+ Parses /etc/ssh/sshd_config
+
+ This module is compatible with Augeas 1.4.0, but is not loaded by default.

+About: Reference
+ sshd_config man page.
+ See http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&sektion=5

+About: License

+
+About: Lens Usage
+ Sample usage of this lens in augtool:
+
+ * Get your current setup
+ > print /files/etc/ssh/sshd_config
+ ...
+
+ * Set X11Forwarding to "no"
+ > set /files/etc/ssh/sshd_config/X11Forwarding "no"
+
+ More advanced usage:
+
+ * Set a Match section
+ > set /files/etc/ssh/sshd_config/Match[1]/Condition/User "foo"
+ > set /files/etc/ssh/sshd_config/Match[1]/Settings/X11Forwarding "yes"
+
+ Saving your file:
+
+ > save
+
+
+About: CAVEATS
+
+ In sshd_config, Match blocks must be located at the end of the file.
+ This means that any new "global" parameters (i.e. outside of a Match
+ block) must be written before the first Match block. By default,
+ Augeas will write new parameters at the end of the file.
+
+ I.e. if you have a Match section and no ChrootDirectory parameter,
+ this command:
+
+ > set /files/etc/ssh/sshd_config/ChrootDirectory "foo"
+
+ will be stored in a new node after the Match section and Augeas will
+ refuse to save sshd_config file.
+
+ To create a new parameter as the right place, you must first create
+ a new Augeas node before the Match section:
+
+ > ins ChrootDirectory before /files/etc/ssh/sshd_config/Match
+
+ Then, you can set the parameter
+
+ > set /files/etc/ssh/sshd_config/ChrootDirectory "foo"
+
+
+About: Configuration files
+ This lens applies to /etc/ssh/sshd_config
