Monitor Zeroconf advertisements:

avahi-browse --all --resolve

To look for just SSH services use the following command. Note the rather cryptic type name that you must use. You may also find it useful to add the --resolve option.

avahi-browse _ssh._tcp
avahi-browse --resolve _ssh._tcp

The --dump-db option is almost totally useless since it lists the human readable names of the service types, but it does not give you the actual name that you need to use to browse that service. For example, --dump-db will list SSH Remote Terminal as one of the service types, but to actually browse for that service you need to use the type name of _ssh._tcp, which is a name I will never remember. You can't use --dump-db to remind yourself of this.

GUI browser

The avahi-discover package has a simple GUI browser. This is the equivalent of the command-line tool avahi-browse.


If you want Avahi to publish your SSH service you must create a service config for it. You can usually just copy the example one and use it without editing it.

cp /usr/share/doc/avahi-daemon/examples/ssh.service /etc/avahi/services/.

If that example is not available then the following should work if copied to /etc/avahi/services/ssh.service.

<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
  <name replace-wildcards="yes">%h</name>
