Running Avahi for automatic IP address configuration in the absence of DHCP services, I've encountered an issue where Coherence does not correctly detect the IP address of the ethN:avahi interface alias. The system is running Debian Sarge, and Coherence v 0.6.6.2.
Here is the relevant ifconfig output:
eth0:avah Link encap:Ethernet HWaddr <hwaddress>
inet addr:169.254.7.45 Bcast:169.254.255.255 Mask:255.255.0.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Interrupt:21
Here is the .coherence config file:
<config>
<logging level="warning">
<logfile active="no">coherence.log</logfile>
</logging>
<plugin active="yes">
<content>/tmp</content>
<uuid>dd717c09-e1ee-4e96-a9b3-df74d170353e</uuid>
<name>Test FS Store</name>
<backend>FSStore</backend>
</plugin>
<controlpoint>no</controlpoint>
<use_dbus>no</use_dbus>
<web-ui>no</web-ui>
<interface>eth0</interface>
</config>
Here is the error message:
WARN coherence May 10 16:19:20 detection of own ip failed, using 127.0.0.1 as own address, functionality will be limited (coherence/base.py:308)
If I change the Avahi auto-ipd.action script so that the interface name doesn't include ":avahi" and update the .coherence file accordingly, the warning does not appear.
I'd guess it has something to do with the length of the interface name, but I don't know that for sure.
