- Partial WORKAROUND -
The error message in question gets generated here:
/etc/dhcp3/dhclient-exit-hooks.d/zzzz_dhcdbd
Where we have the following code:
if [ -n "${dhc_dbus}" ]; then
/usr/bin/dbus-send \
--system \
--dest=com.redhat.dhcp \
--type=method_call \
/com/redhat/dhcp/$interface \
com.redhat.dhcp.set \
'string:'"`env | /bin/egrep -v
'^(PATH|SHLVL|_|PWD|dhc_dbus)\='`";
fi;
Now this always gives an error message about a bad path because "
/com/redhat/dhcp/$interface" doesn't exist.
Also this part:
'string:'"`env | /bin/egrep -v '^(PATH|SHLVL|_|PWD|dhc_dbus)\='`"
just spits out all the environment variables. That doesn't sound right. I
think this is supposed to pass information about the interaface to a database
or something, but envirnment variables don't seem right. I would guess that
this is supposed to be passing permanent leases to the dhcdbd.
Anyway I have attached the workaround patch which fixed the Network
Manager interaction for me.
Basically it changes "/com/redhat/dhcp/$interface" to "/"
This stops the error and gets rid of the need to restart my network interface
every time I connect to a network. I still contend it should be doing
something other than passing environment variables, but I don't know enough
about dbus to fix it. Hopefully, this will show the right person where to look.
