Folks,
I am defining a new service for Avahi to vend to the network. It starts
up and all of the parameters are correct and it can be found by my custom
software and by "Bonjour Browser". But then Avahi stops advertising the service
in about 5 minutes. This is running a "stock" Fedora 11 on VMware on a Mac. To
simplify the configuration, I've given the linux image a static IP address and
it is bridged onto my local network. Internet access is working properly. SSH,
_ssh._tcp, as delivered by Fedora, also suffers from this problem.
Below is as much data as I know how to dig up about Avahi's status. I,
of course, can perform any system experiments any of you might desire to get
more data about this problem. I am confused and would appreciate your help.
Thanks in advance.
Anon,
Andrew
P.S. I have already submitted these service identifiers, _rest._tcp and
_rest-http._tcp, to the DNS-SD registry. (These are named similarly to my
submissions made in an earlier life, _ws._tcp, _soap._tcp and _upnp._tcp.)
Since I'm now using REST services, I believe they need their own identifier.

Using avahi-daemon 0.6.25
Here are the two services:
<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<name replace-wildcards="yes">%h</name>
<service>
<type>_ssh._tcp</type>
<port>22</port>
</service>
</service-group>
<?xml version="1.0" standalone='no'?><!--*-nxml-*-->
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>

<service>
<type>_rest._tcp</type>
<port>3000</port>
<txt-record>txtvers=1</txt-record>
</service>
</service-group>
Here is the result of ip addr:
