Can't ping from root, yet network still available
I'm having a problem here. As I said in the title, root can't ping google, yet seamonkey has no trouble connecting to google whatever. I have some output I can show you.:
Code:
root@caitlyn:~/RetroArch# ping www.google.com
PING www.google.com (216.58.193.132) 56(84) bytes of data.
^C
--- www.google.com ping statistics ---
13 packets transmitted, 0 received, 100% packet loss, time 11999ms
root@caitlyn:~/RetroArch#
What is going on here? I can obviously use the network, assuming that this posts without a problem, but I can't seem to ping anyone out there. I recently got a new modem, which seems to provide more reliable connections, but meanwhile I can't update my systems because I can't ping anybody. Please help!

Have you other machines on your local network? Can you ping those?
My immediate thought is that icmp echo is being filtered.
Check with your ISP, perhaps?
Thanks

Have you tried pinging an external IP? That could help determine if it's a DNS issue with root vs something else.

I don't know what that hitronhub.home thing is about. I didn't add that.

A quick web search indicates that domain hitronhub.home is from hitronhub routers. The resolv.conf file indicates using dhcpcd and the file is being updated dynamically from the router based on the DHCP exchange.nameserver 192.168.0.1 entry means there needs to be a DNS name server at that address. Likely this IP address is the router.

How do I do that? How do I connect directly to the ISP without going through the router? The router is the cable modem. The ISP supplied it.

With an Ethernet cable.
Try
dig +trace www.google.com and
traceroute www.google.com . The commands should provide some clues.

Can you show the dig and traceroute commands with a regular user?

The PC connects directly to the ISP modem. Unplug the Ethernet cable between the modem and router and connect the modem to the PC.
The traceroute is not getting past the router. At the least reboot the sucker.
