<para>Remote connections are easily made by typing the

<para>You can bookmark these &URL;'s, however, please
read the

<emphasis>securely save passwords</emphasis>. For connecting to
multiple locations, bookmark these &URL;'s and open
them one by one, or open them all together by using
&panel-profiles-lnk;. To switch from one to another
location, just open a &foldertabs-lnk; for
each.</para>
<para>There are three ways to start a remote connection:

<para>Select
<emphasis role="bold">

<guimenuitem>New Net Connection</guimenuitem>
</menuchoice>
</emphasis>which will pop-up a dialog that will ask for the
remote site details. This dialog is handy if you are not used
to type remote &URL;'s in the Location Toolbar.
Leaving the password and user name fields empty will log you
in as anonymous. NOTE: we are planning to rewrite this dialog
window.</para>

<para>&krusader; is a file manager that supports
remote connections via &tdeioslaves1-url;, but if you
are looking for even more advanced remote connections features,
&eg; an advanced &FTP;-client we
recommend you to use &eg;
&kasablanca-url; or
&kftpgrabber-url;.</para>

feedback about this chapter is appriciated. Thanks!</para>
<note>
<para>This works on a &debian; system, so it will work on &debian; and derivatives (&kubuntu; &etc;), though
it should work on other Linuxes as well.
We assume that you have <link linkend="gloss-ssh">SSH</link> installed, configured and working on
every machine on LAN you want to connect to/from.
There are plenty of very good tutorials about <link linkend="gloss-ssh">SSH</link> on the net, &eg;
at <ulink url="http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch17_:_Secure_Remote_Logins_and_File_Copying">linuxhomenetworking.com</ulink>
or just google for it. We use the default <link linkend="gloss-ssh">SSH</link> port (22) for this chapter.
Remember to change it if you use different one. All modifications, editing &etc; must be done as root.

<para>
Let's start with installing all the packages we need:
<screen>
<prompt>#</prompt> <userinput><command>apt-get install</command> <option>avahi-daemon libnss-mdns tdednssd</option></userinput>
</screen>
Everything is installed, now let's do some configuration. First, we need our services to be announced on LAN.
That's why we installed avahi-daemon: it represents your machine on local network and allows other applications
to publish services they provide. Avahi-daemon comes with example <filename>ssh.service</filename> configuration
file found in <filename>/usr/share/doc/avahi-daemon/examples</filename> . In order to get the service to be
announced on LAN we need to copy this file to <filename>/etc/avahi/services</filename> directory:
<screen>
<prompt>#</prompt> <userinput><command>cp</command> <option>/usr/share/doc/avahi-daemon/examples/ssh.service /etc/avahi/services</option></userinput>
</screen>
Now we need fish:/ protocol to be announced too, so we use an ssh.service file as a template for fish.service:
<screen>
<prompt>#</prompt> <userinput><command>cp</command> <option>/etc/avahi/services/ssh.service /etc/avahi/services/fish.service</option></userinput>
</screen>
This file is just a copy of ssh.service, Edit the <filename>fish.service</filename> file and replace
"Remote Terminal on %h" with "Fish to %h" and "_ssh._tcp" with "_fish._tcp".
Here's how it looks after edit:
<programlisting>
&lt;?xml version="1.0" standalone='no'?&gt;&lt;!--*-nxml-*-->
&lt;!DOCTYPE service-group SYSTEM "avahi-service.dtd"&gt;
&lt;!-- $Id: remote-connections.docbook,v 1.6 2007/05/02 18:07:28 codeknight Exp $ -->

&lt;service-group>
&lt;name replace-wildcards="yes">FISH to %h&lt;/name>
&lt;service>
&lt;type>_fish._tcp&lt;/type>
&lt;port>22&lt;/port>
&lt;/service>
&lt;/service-group>
</programlisting>
Save the modified file.
Now we need to create a new file <filename>_fish._tcp</filename>, open a text editor and add the next lines:
<programlisting>
Name=FISH Protocol (ssh)
Type=_fish._tcp
UserEntry=u
PathEntry=path
PasswordEntry=p
</programlisting>
And save the file <filename>/usr/share/apps/zeroconf/_fish._tcp</filename>
Do the same on each machine on your LAN, then restart avahi-daemon:
<screen>
<prompt># /etc/init.d/</prompt> <userinput><command>avahi-daemon</command> <option>restart</option></userinput>
</screen>
Than open &krusader; and type in location-toolbar-lnk: <filename>zeroconf:/</filename> to open the
<link linkend="gloss-zeroconf">zeroconf</link> connection.
Enter the <guilabel>Fish Protocol</guilabel> directory. Inside you'll find the links to each machine that
announced <filename>fish:/</filename> on your LAN, the location-toolbar-lnk: will point to
<filename>zeroconf:/_fish._tcp</filename> Double clicking on any of these machines,
them will bring up the password prompt, asking you for yor ssh key passphrase (if password was set).
Enter your passphrase. Congratulations: you connected to remote machine using &krusader;!
