How to test if your Quic UDP network configuration is correctly. http://storjnet.info/ping_my_node Run the following command on the host to change network protocol settings. makes it persistent across reboots echo "net.core.rmem_max=2500000" >> /etc/sysctl.conf sysctl -w net.core.rmem_max=25000…

Look what I found somwhere on internet: Modify Kernel parameter in /etc/sysctl.conf for permanent change After modifying the kernel parameter in the /etc/sysctl.conf, execute sysctl –p to commit the changes. The changes will still be there after the reboot. vi /etc/sysctl.conf # sysctl –p Modify k…

[image] SGC: Run the following command on the host to change network protocol settings. -w makes it persistent across reboots sysctl -w net.core.rmem_max=2500000 Have you checked? Is it permanent? Do you think so? (as usual you are used to) sysctl --help

IBM documentation usually has some excellent tips and tricks, and very well documented about how and why. i already optimized my network setting a long time ago, but generally what i learned from that rabbit hole was that there are way to many bad suggestions about changing network setting for opti…

[image] SGC: if you do decided to test it out do let us know, if its persistent or not… It is not persistent, it only lasts until shutdown. It is just as @Krawi wrote: [image] Krawi: Edit /etc/sysctl.conf and add these lines

[image] SGC: -w, --write enabling writing of a value to a variable

which seems again doesn’t tell you if that is persistent or temporary… ofc since we can change variables without using -w then one can deduce that it most likely means that it’s persistent… i just don’t think it’s written in a way that cannot be misunderstood or requires prior knowledge… like say…

Didn’t you feel like rebooting the system to check?

hell no, its a soft failure even if it doesn’t work… barely changes anything…everything will work… the storagenode at worst gets slightly more latency. so i can deal with that if it turns out to be a problem … rebooting my server is a bother…

man sysctl info about the -w: -w, --write Use this option when all arguments prescribe a key to be set. Nothing about the destination for this action, is it memory, a file, a piece of rock, wood, steel or the surface of the next SpaceX rocket?

But you’re writing the manual: " [UDP QUIC configuration guide for linux / docker]" and you mislead others …

it will work… else i can correct it i did consider doing an echo whatever into whatever sysctl or a sysctludp.conf or something… but just made everything so much more difficult, this was simple and i’m sure somebody will complain if it doesn’t work. and the --help sort of says it works, other peo…
