#177 0.99b2 - Network not keeping state ;

[Jeff Balderson]

I upgraded one of my Gentoo Linux systems to 0.99b2.
I've noted two problems:

1) I noticed that the 100Mb ethernet interface in the
system kept going red at 6Mb. I attempted to correct
this situation by modifying the network test line in
uxmon-net:

localhost speed=100000 network

According to 'testers -t network', "speed=" should be
followed by a value in kbits/s (which I assume to mean
a numerical value only). In this case, 100000 would be
100Mbit/s. The reds went away, but the "InLoad" and
"OutLoad" stayed at 0% and green, regardless of how
busy I made the interface (should have been around 53%
for my test). The InRate and OutRate did show their
correct values.

I then tried:

localhost speed=100Mb/s network

the syntax for which I found in either a Bug report or
mailing list archives. Same result.

I finally removed "speed=" in uxmon-net, went into
lxNetwork.pm and changed the following:

$iface->{"ifSpeed"} = 100000000;

This fixed the problem, mostly -- see #2, below. So,
it looks like the code which parses "speed=" has problems.

As far as setting the "speed=" variable for the network
test, I prefer the numerical-only format of
"speed=100000" (in Kbit/s), assuming it's up to a vote.

2) Once that value was set in lxNetwork.pm, the
interface correctly went yellow when the load was
around 53%, however, during the next five minute
interval, the OutRate went to 0. It continuted to
oscillate between the real value (53% -- 6.6MB/s) and
0. My network load test was pulling about 100GB of
data across an NFS connection (for i in *.dmp; do cat
$i > /dev/null; done), so the network load should have
been pretty consistent at around 6.6MB/s.

1) Sorry, I still cannot reproduce that, here. I set speed
to something like speed=200Mb/s, check in status.log where
the correct speed is reported, add debugging code that also
reports the correct speed - it's certainly a Gentoo problem
(just kidding). Sorry, no reproduction means no fix :-(.
Probably there's something silly I just don't see.

As for voting: no need to do this, you can use whatever you
want, "speed=100000", "speed=10000kb/s", "speed=100Mb/s",
"speed=0.1Gb/s", they are all the same.

2) Hmh, this is probably the kernel's byte counter which is
overflowing. Assuming it's an unsigned 32-bit int it'll
restart from zero every 12 minutes at 6.6MB/s.

For some reason, InLoad/OutLoad perf data isn't getting
reported. from my status.log:
