If you are trying to connect 2 monitors (HDMI + USB C), you might find that only USB C and the laptop monitors is working in Fedora 32. After I search around, here is the simple solution. Create a file (any file name end with extension .conf) under folder /etc/X11/xorg.conf.d. I name it 11-nvidia-prime.conf. (Copy from ubuntu). Enter the lines below and reboot.  [root@localhost xorg.conf.d]# cat 11-nvidia-prime.conf Section "OutputClass"     Identifier "Nvidia Prime"     MatchDriver "nvidia-drm"     Driver "nvidia"     Option "AllowEmptyInitialConfiguration"     Option "IgnoreDisplayDevices" "CRT"     Option "PrimaryGPU" "Yes" EndSection I believe this solution should be working for Fedora 25 and above. Leave me a message if you have question.

Recently I've playing with zabbix installation and I faced this issue. From the Zabbix agent issue command zabbix_agentd -s zabbix-agent -k "openvpn[x.x.x.x]" manage to retrieve text value. But from the zabbix server issue command zabbix_get -s zabbix-agent -k "openvpn[x.x.x.x]" empty value return from the zabbix agent. The zabbix script look like this. Timeout=30 UserParameter=openvpn[*],nmap -sT $1 -p 443 |grep 443 | awk -F " " '{print $$2}' After searching the around, i found the solution. First add the capabilities to Nmap. sudo setcap cap_net_raw,cap_net_admin,cap_net_bind_service+eip /usr/bin/nmap Then add additional parameter into the script. Timeout=30 UserParameter=openvpn[*],nmap --privileged -sT $1 -p 10443 |grep 10443 | awk -F " " '{print $$2}' Once the agent restarted, the script will be working again. ---

If you run hping command without root permission or without sudo and you receive this error : [open_sockraw] socket(): Operation not permitted [main] can't open raw socket This command might be able to help you. sudo setcap cap_net_raw+ep /usr/bin/hping3 (or any location of the hping command) setcap command is to set file capabilities. What are filesystem capabilities?    For the purpose of performing permission checks, traditional Unix implementations distinguish two categories of processes: privileged processes (whose effective user ID is 0, referred to as superuser or root), and unprivileged processes (whose effective UID is non-zero). Privileged processes bypass all kernel permission checks, while unprivileged processes are subject to full permission checking based on the process's credentials (usually: effective UID, effective GID, and supplementary group list).  Starting with kernel 2.2, Linux divides the privileges traditionally associated...

Magic Quadrant for WAN Edge Infrastructure - Gartner Published 18 October 2018 - ID G00351467 - 61 min read WAN edge infrastructure is changing rapidly as I&O leaders responsible for networking face dynamic business requirements, including new application architectures and on-premises and cloud-based deployment models. I&O leaders can use this research to identify vendors that best fit their requirements. Strategic Planning Assumption By year-end 2023, more than 90% of WAN edge infrastructure refresh initiatives will be based on virtualized customer premises equipment (vCPE) platforms or software-defined WAN (SD-WAN) software/appliances versus traditional routers (up from less than 40% today). Market Definition/Description WAN edge infrastructure enables network connectivity from distributed enterprise locations to access resources in both private and public data centers as well as cloud (as a service). It is typically procured by senior networking leaders wit...
