ssh client. The public part of the key will be needed on the fli4l router and is provided to
it by SSHD_PUBLIC_KEY_x or SSHD_PUBLIC_KEYFILE_x.
For further informations see manual pages for ssh and its components res. the documen-
tation for putty (http://www.chiark.greenend.org.uk/~sgtatham/putty/).
SSHD_PUBLIC_KEY_x Provide the public part of each user’s key here who should be able
to access flil4 via ssh. The easiest way is cut and paste it from a terminal window.
Example:
SSHD_PUBLIC_KEY_1='1024 ... username@hostname'
Important: The key does not contain carriage returns. Puttygen will insert those even-
tually while doing cut-and-paste. They will have to be deleted again.
SSHD_PUBLIC_KEYFILE_N Default setting: SSHD_PUBLIC_KEYFILE_N=’0’
Instead of copying the content of the public part of the key to sshd.txt you could copy it
directly to the opt archive. This works like described for SSH_CREATEHOSTKEYS. Copy the
public part of the key to the directory config /etc/ssh.
SSHD_PUBLIC_KEYFILE_x The file name of the public key in directory
config /etc/ssh.
SSHD_PUBLIC_KEYFILE_1='root@fli4l'
SSH_CLIENT_PRIVATE_KEYFILE_N Default setting:
SSH_CLIENT_PRIVATE_KEYFILE_N=’0’
If you want to use private keys for the ssh or plink client for login at a ssh server you could
copy them to the directory config /etc/ssh. This works the same way as described in
SSH_CREATEHOSTKEYS. Copy your private key to the directory config /etc/ssh. Private
keys in OpenSSH format will be automatically converted to dropbear format on each
boot.
SSH_CLIENT_PRIVATE_KEYFILE_x The file name of the private key
in directory config /etc/ssh.
SSHD_PRIVATE_KEYFILE_1='babel@rootserver'
4.19.2. Installation Of Dbclient
OPT_SSH_CLIENT Default setting: OPT_SSH_CLIENT=’no’
To use a pure ssh2/scp client activate dbclient from dropbear by setting OPT_SSH_CLIENT
to ’yes’. The advantage of this client is that it shares program code with the dropbear ssh
server. This saves a lot of space in the OPT archive. Dbclient is more or less compatible
with ssh/scp client, its command syntax is similar. A symbolic link to /usr/bin/ssh res.
/usr/bin/scp will be created to make ssh host res. scp source target working
out of the box.
