Iperf's UDP defaults are low bandwidth and I think focused on latency. You can explicitly set a desired bitrate for UDP with a parameter. Try that and see if things are better.
Used iperf -ub 100 -c [server-ip] as the command (should be 100 Mbps bandwidth), and i still get the same 1Mbps
server is running using iperf -us

Could you give me the output of
hexdump /sys/bus/nvmem/devices/meson-efuse0/nvmemFor all 4 boards? (unless all identical outputs, then 1 will do. ;-)
Did you want these on boot? or just whenever? Anyways they all look just like as you said
0000000 0000 0000 0000 0000 0000 0000 0000 0000 * 00000c0I ran iperf between 2 PI's and I noticed something strange:
When I use UDP mode, I get around 1.03 Mbps on transfer rates (average over 10 second intervals)
When I use TCP mode, I get around 94 Mbps transfer rates
I can also try to do an iperf from another known device, but I don't have a linux machine available outside of the lepotatoes at the moment, so I'll do that another time.

With the 4 potatoes I have, I (after many tries) successfully updated all 4 of them. I ran the docker install script on all 4 (which usually would crash 2 or 3 of them, but didn't crash.).
I'm running some services on them, will probably add some more tonight and also start executing traffic through them (they don't have much traffic as of right now.)
So far it seems fixed. However, I did notice that the internet speed feels slow. I'm not sure if this is a potato problem or the servers I"m downloading from, so I'll try running some iperf tests later tonight also.
Edit: I also want to mention that
for some reason, it worked fine when I rebooted my first potato The other potatoes required an ifdown; ifup before being able to use the internet. Probably will look into that more again too.
-
Is there a build number that I can confirm that I updated to it?
Also want to mention that it feels bad when you're trying to download a patch for your ethernet to not crash and ur ethernet crashes haha.
-
Thanks guys for the updates.
Is a build with the EEE fix available on any downloadable build at the moment? I would like to try it myself and see if I'm able to do what I originally intended to do before I opened this thread.
-
Is there any action at the moment to take care of this issue? From what I'm hearing, this is a valid issue, so has this been added to the "todo" list? if so, what's the current status?
-
Different potato, but should be the same exact configuration other than the local IP being 1 off.

If I remember correctly, allow-hotplug eth0 pretty much does a similar thing as auto eth0,
So, as I expected on reboot, changing to auto eth0; didn't do anything.

Why did you not provide output of 'sudo armbianmonitor -u' as requested?
I was not referring to your answer, and I didn't see your answer since I was skimming by really quick, so I apologize for that.
I will try switching to auto. It was on these settings because they were the defaults given to me when I installed Armbian (I didn't change any of the keywords)
I've already resolved it one way, so I don't think armbianmonitor will be necessary. I am aware of this since I've already been providing armbianmonitor in my previous thread.
Thanks for all the help.

Yeah, I tried the top answer on that site, and it worked. I don't know what people think of editing base files, but it's good enough for me.

Whenever I've been booting up these potatoes, network never works right off the bat when you're using static IPs.

Then I tried this answer: https://unix.stackexchange.com/questions/275428/i-can-ping-ips-but-cant-resolve-domains
And it works...BUT resolv.conf is overwritten on reboot, so I would have to write into this file every time I boot up. Shouldn't this be something that's automatic on boot?

I changed /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor to performance

I went onto the computer directly, reset the ethernet, and did armbianmonitor -u. (Ethernet was dead and couldn't do apt-get update)

That's weird and might be why you see these errors. Could you check the outut of cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and if it says anything other than performance do sudo echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor (please note that this setting won't survive a reboot) and then redo your testing?
BTW: Is wget https://git.kernel.org/torvalds/t/linux-4.14-rc5.tar.gz a good way to reproduce the issue for you?1) cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor returns ondemand
2) I'll do some testing when I get back home from work.
3) I just did the wget command, and it works fine (didn't change scaling_governor)
4) I'll try changing scaling_governor to performance and then reinstall docker-ce, and then redo the same stuff I was doing before.
-
I'm going to uninstall docker-ce and just use them and see if I still crash.
For my other question of not being able to access the internet on boot, am I doing something wrong here?
/etc/network/interfaces
# Wired adapter #1 allow-hotplug eth0 no-auto-down eth0 iface eth0 inet static address 192.168.5.200 netmask 255.255.255.0 gateway 192.168.5.6 dns-nameservers 8.8.8.8 192.168.5.6For more context,
I have it setup to static IP, but every time on boot, i have to do sudo ifdown eth0; sudo ifup eth0 every single time to get internet access. I can SSH it just fine, and I can ping 8.8.8.8, but I can't resolve any hostnames like nslookup google.com
Edit: I uninstalled docker-ce and so far, it hasn't crashed. I've done some stress tests, iperfs, and it seems to be working fine... Will keep checking. Maybe something wrong with docker with amlogic?
-
@V10lator Nope, just downloaded from armbian's site.
Mine looks like this
CONFIG_CPU_FREQ_GOV_ATTR_SET=y CONFIG_CPU_FREQ_GOV_COMMON=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=m CONFIG_CPU_FREQ_GOV_USERSPACE=m CONFIG_CPU_FREQ_GOV_ONDEMAND=y CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m CONFIG_CPU_FREQ_GOV_SCHEDUTIL=y
-
I've ran into this problem a few times without docker for things like sudo apt-get update, but most of the time that I've ran into this was something involved with docker. Either running the get.docker script, installing docker, or downloading a container (i.e. python2.7-slim). I can test later today and see if other workloads cause this to happen.

Sorry, I should've checked before posting.

-
Also, I've noticed with this particular version, static IPs aren't working on boot and I have to do ifdown/ifup to make it work.
It used to work fine with the previous versions. I'm not sure what's wrong with that either.
-
@TonyMac32
I'm on version 4.13, which I downloaded yesterday. From your post, I'm assuming there's a 4.15 version?
I'll try to reproduce it (it happened again as I was downloading the python2.7 docker container) and see.

So, I've been struggling to figure out the reason behind this problem.
I have 4 Le Potatoes, all connected to a 100 mbps switch. Each of them have a 32 GB Samsung SD Card EVO.
Initially, the problem was that my SSH session would hang at random usually when I download something. I can't SSH again unless I reboot the PI (I didn't bother waiting longer than 5min)
Initially, I thought SD Cards were bad, I moved them around, done reinstalls. I'm also using SD Formatter to format them and Etcher to install them.
Still, this freezing problem had no consistent behavior according to PI hardware or the SD cards..
For Power, I'm using Anker 40W 4-Port USB Wall Charger, which it should (I think) be enough power. I've checked all the cables using my phone to verify.
I plugged HDMI into them, and see if they were still running after those SSH crashes. (why didn't I do this earlier) I ssh'd into them and see what happened when the "crash" behavior happened.
After SSH hangs, I check the PI, and the computer is still running as usual.
I reboot the PI, and I start doing some downloads, and then now I see the network hang I get from ssh. To me it seems like the ethernet driver is crashing or something.
I'm not sure what else to try for debugging / what the problem is. Send Help.

If you're just installing a fresh image, you can just grab the latest nightly build, then do a sudo apt-get update/upgrade cycle to get the latest nightly version.
If you're doing it on an already installed image, and you're not on nightly builds, then you have to follow this: http://www.armbian.com/kernel/
You could use armbian-config if you have it, but in my experience, I can't even use it properly.
