Template: ssh/new_config
Type: boolean
Default: true
_Description: Generate new configuration file
This version of OpenSSH has a considerably changed configuration file from
the version shipped in Debian 'Potato', which you appear to be upgrading
from. I can now generate you a new configuration file
(/etc/ssh/sshd.config), which will work with the new server version, but
will not contain any customisations you made with the old version.
.
Please note that this new configuration file will set the value of
'PermitRootLogin' to yes (meaning that anyone knowing the root password
can ssh directly in as root). It is the opinion of the maintainer that
this is the correct default (see README.Debian for more details), but you
can always edit sshd_config and set it to no if you wish.
.
It is strongly recommended that you let me generate a new configuration
file for you.
Template: ssh/protocol2_only
Type: boolean
Default: true
_Description: Allow SSH protocol 2 only
This version of OpenSSH supports version 2 of the ssh protocol, which is
much more secure. Disabling ssh 1 is encouraged, however this will slow
things down on low end machines and might prevent older clients from
connecting (the ssh client shipped with "potato" is affected).
.
Also please note that keys used for protocol 1 are different so you will
not be able to use them if you only allow protocol 2 connections.
.
If you later change your mind about this setting, README.Debian has
instructions on what to do to your sshd_config file.
Template: ssh/use_old_init_script
Type: boolean
Default: false
_Description: Do you want to continue (and risk killing active ssh sessions)?
The version of /etc/init.d/ssh that you have installed, is likely to kill
all running sshd instances. If you are doing this upgrade via an ssh
session, that would be a Bad Thing(tm).
.
You can fix this by adding "--pidfile /var/run/sshd.pid" to the
start-stop-daemon line in the stop section of the file.
Template: ssh/forward_warning
Type: note
_Description: NOTE: Forwarding of X11 and Authorization disabled by default.
For security reasons, the Debian version of ssh has ForwardX11 and
ForwardAgent set to ``off'' by default.
.
You can enable it for servers you trust, either in one of the
configuration files, or with the -X command line option.
.
More details can be found in /usr/share/doc/ssh/README.Debian
Template: ssh/insecure_rshd
Type: note
_Description: Warning: rsh-server is installed --- probably not a good idea
having rsh-server installed undermines the security that you were probably
wanting to obtain by installing ssh. I'd advise you to remove that
package.
Template: ssh/insecure_telnetd
Type: note
_Description: Warning: telnetd is installed --- probably not a good idea
I'd advise you to either remove the telnetd package (if you don't actually
need to offer telnet access) or install telnetd-ssl so that there is at
least some chance that telnet sessions will not be sending unencrypted
login/password and session information over the network.
Template: ssh/encrypted_host_key_but_no_keygen
Type: note
_Description: Warning: you must create a new host key
There is an old /etc/ssh/ssh_host_key, which is IDEA encrypted. OpenSSH
can not handle this host key file, and I can't find the ssh-keygen utility
from the old (non-free) SSH installation.
.
You will need to generate a new host key.
