If dbclient’s known hosts should be saved permanently the file known_hosts from the
directory /.ssh on the router has to be copied to config/etc/ssh. This works in the same
as with a generated host key. In the following example the fli4l directory (fli4l’s boot
medium is generated there) is found at /home/babel/fli4l-3.10.1 . All config files are in
directory config.babel.
cd /home/babel/fli4l-3.10.1
mkdir -p config.babel/etc/ssh
scp fli4l:/.ssh/* config.babel/etc/ssh
4.19.3. Installation Of A Plink Client
OPT_PLINK_CLIENT Default setting: OPT_PLINK_CLIENT=’no’
Installs a ssh1/ssh2/telnet client on the fli4l router. plink is the Unix version of the well
known PuTTY program for Windows. Executing plink on the fli4l router displays a help
page for using plink.
If plink’s known hosts should be saved permanently the file sshhostkeys from the directory
/.putty on the router has to be copied to config /etc/plink. This works in the same
as with a generated host key. In the following example the fli4l directory (fli4l’s boot
medium is generated there) is found at /home/babel/fli4l-3.10.1 . All config files are in
directory config.babel.
cd /home/babel/fli4l-3.10.1
mkdir -p config.babel/etc/plink
scp fli4l:/.putty/* config.babel/etc/plink

4.20. TOOLS - Additional Tools For Debugging
Package TOOLS provides some Unix programs mostly used for administration and debugging.
Other ones like wget are used i.e. for catching the first (ad-)page of some providers. By
setting the value ’yes’ the mentioned program is copied to the fli4l router. Default setting
is ’no’. The programs are only described in short, how to use them is described in their
repective man pages which can be found in your favourite linux distribution or online at:
