而家政府講嗰啲嘢出嚟啊好多人都唔明添 可能要同你地講要政治正確先睇得明

what's that mean

換過講法先
呢啲人應該係違反咗中共政府嘅政策 導致呢啲疫情係醫院之內發生

-,-

still not understand

總之你食嗰舊三文治附近冇人就得㗎啦 包括好似林鄭推行嘅 落雨都要出街食飯咁樣

原來公司d laptop依家裝左crowdstrike

900MB/s = 8100 mbps

TIL how to set site:site vpn in wireguard

https://github.com/githubixx/ansible-role-wireguard
ah

i thought the author was stevefan1999

本身都想寫一個wireguard ansible playbook添

clone everything and push to your own repo

bash-5.0# ip route
default via 10.42.4.1 dev eth0
10.42.0.0/16 via 10.42.4.1 dev eth0
10.42.4.0/24 dev eth0 proto kernel scope link src 10.42.4.94
ah, there you go

this is why i cant ping 10.43.0.1 from my node

so technically if i set my source ip to 10.42.4.0, it should ping right

Set source IP to a network address? Steve you are a genius

Wow!
Amazing!

hmm

not right

ping -I 10.42.4.1 10.43.0.1
doesn't work

but i can curl https://10.43.0.1 🤔

but there is no route at all...

 15   900 KUBE-MARK-MASQ  tcp  --  *      *      !10.42.0.0/16         10.43.0.1            /* default/kubernetes:https cluster IP */ tcp dpt:443
  161  9604 KUBE-SVC-NPX46M4PTMTKRN6Y  tcp  --  *      *       0.0.0.0/0            10.43.0.1            /* default/kubernetes:https cluster IP */ tcp dpt:443

a

there you go

ah, because k8s uses iptables for proxy by default

咦

咁姐係話pritunl link嘅direct link mode就係default all transit

以下嗰啲內容係咪CCNA教?

i tried this insane idea of running wireguard cni within wireguard tunnel

for some reason vxlan doesnt work

i assume it is because wg, as a layer 3 protocol, cannot fully support vlan

if i tried to use vxlan, it is extremely laggy

i dont really want to get to the bottom of this but im still curious for the proper answer of this

i guess the performance can be hit by 50%, so 500mbps uplink is effectively 250mbps after this crazy shit
