Command:
[root@host ~]# netstat -lupn | grep 443
Results in:
udp 0 0 0.0.0.0:443 0.0.0.0:* 3603/litespeed (lsh
udp 0 0 0.0.0.0:443 0.0.0.0:* 3603/litespeed (lsh
udp6 0 0 :::443 :::* 3603/litespeed (lsh
udp6 0 0 :::443 :::* 3603/litespeed (lsh
---------------------------------------------------------
So, in CSF Firewall
Enabled UDP 443 - both in and out
Turned LF_SPI off
UDPFLOOD was already off.
Checked netstat -lupn | grep 443 again:
[root@host ~]# netstat -lupn | grep 443
udp 0 0 0.0.0.0:443 0.0.0.0:* 3603/litespeed (lsh
udp 0 0 0.0.0.0:443 0.0.0.0:* 3603/litespeed (lsh
udp6 0 0 :::443 :::* 3603/litespeed (lsh
udp6 0 0 :::443 :::* 3603/litespeed (lsh
-------------------------------------------------------
Command:
[root@host ~]# alt-svc:quic=":443"; v="35,37", or "http/2+quic/37"
Outputs:
-bash: alt-svc:quic=:443: command not found
-bash: or: command not found
-------------------------------------------------------
https://http3check.net/ NOW shows:
QUIC is supported
HTTP/3 is supported
YET...
Chrome HTTP/2 and SPDY indicator, shows green lightning bolt only AFTER refreshing page
Firefox shows blue lightning bolt for pages without refreshing.
Redbot, securityheaders.com, and other header checkers still show HTTP/1.1 200 OK
Chrome developer lighthouse still shows HTTP1.1 for pages (php).
---------------------------------------------------
Any ideas?
Thanks, Ian.
