Hello I am experiencing a weird problem with my RapberryPi4 8 GB RAM setup. RPi4 is connected via ethernet to the home router.
I start an ssh session from my Windows PC at work using Mingw64 to the home RPi4: ssh -o ServerAliveInterval=60 -p 50006 -L 5901:127.0.0.1:5901 -L 50012:localhost:50012 user@host Those ports are redirected by the home router to the RPi4 static IP address. I launch vncserver normally: netbsd-raspa4$ vncserver New 'netbsd-raspa4:1 (ramiro)' desktop is netbsd-raspa4:1 Starting applications specified in /home/ramiro/.config/tigervnc/xstartup Log file is /home/ramiro/.config/tigervnc/netbsd-raspa4:1.log netbsd-raspa4$ vncserver -list TigerVNC server sessions: X DISPLAY # PROCESS ID :1 961 netbsd-raspa4$ XFCE4 session is up and running fine. At work, in a Windows PC, I run Tigervncviewer at localhost:5901. It starts working well, responsive enough but some times, many times, it starts going slow, very slow, sometimes it stucks, after some time it starts working ok, and so on. When it is stuck, I cannot even write characters in the launched ssh session, or I can write them very very slow. At that moment, I am able to launch another normal SSH session from the PC at work and works fine, very responsive. I have also tried this with no appreciable improvements: $ cat sshraspa4-vnc-gnuradio.sh-comprimido #!/bin/sh ssh -C -c [email protected] \ -o ServerAliveInterval=60 \ -o ServerAliveCountMax=3 \ -o TCPKeepAlive=yes \ -o IPQos=lowdelay \ -p 50006 \ -L 5901:127.0.0.1:5901 -L 50012:localhost:50012 \ user@host I have also tried something like : ifconfig genet0 mtu 1300 with no improvements. Any ideas to debug this are appreciated. I have also noticed the same problem with a NetBSD amd64. Regards. Ramiro.
