Description poma 2014-10-26 01:03:50 UTC
"Netload-plugin cannot handle predictable interface names."
systemd-udevd: renamed network interface wlan0 to wlp0s4f1u3

This accompanied patch works reliably, long since.
"Workaround for extending the maximum interface name size (+10 chars)"

"Length limit of interface names precludes use of valid interfaces"

Comment 1 poma 2014-10-26 01:10:27 UTC
"Network Monitor applet doesn't accept more than 7 characters in interface name"

Comment 6 Kevin Fenzi 2014-11-09 21:23:44 UTC
Upstream fixed this in a different way. They removed the limit on it entirely... 

Can you please comment on upstream bug: 

and see what might be going on with their fix?

Comment 7 poma 2014-11-21 12:28:38 UTC
1.2.3 broke it even more, in addition - incomplete units display.

The way it works OK:

# This commit didn't solve ifnames lenght problem at all:
# Do not enforce max length for text/device entries (bug #9869)

# So here we go again

Can you expand on "in addition - incomplete units display" ? 

Note that this breakage is why I haven't pushed this to any stable releases.

Comment 9 Kevin Fenzi 2014-11-22 22:07:16 UTC
Please test 1.2.4. Just built in rawhide. 


Comment 10 poma 2014-11-24 18:53:31 UTC
Actually labels were reduced only to "B", but this has now all been resolved, with the addition of "b".
Super duper.

Tested with:
$ rpm -q xfce4-netload-plugin
