Hello everybody,
Thank you Fufu Fang for your quick reply:
With tinc version 1.0.35 and the bellow options at 100% CPu load i get
about 10 MB/s...
PMTU = 1400
PMTUDiscovery = yes
#Cipher = none
Cipher = chacha20-poly1305
Digest = blake2b512
Tried Cipher = none as well and also got 10MB/s with 100% CPU on one
thread the other three available threads are idle.
With inc_1.1~pre17-1.1_amd64.deb and libssl1.1:amd64 1.1.1d-0+deb10u2 I
get the following error:
Apr 04 19:03:19 officelink01 tincd[522]: Error while decrypting:
error:060A7094:digital envelope routines:EVP_EncryptUpdate:invalid operation
installation steps:
wget
http://ftp.nl.debian.org/debian/pool/main/t/tinc/tinc_1.1~pre17-1.1_amd64.deb
dpkg -i tinc_1.1~pre17-1.1_amd64.deb
apt-get -f install
Any speed improvement ideas?
Kind regards,
Jelle
