No route to host until I ping and then it works fine?
Probably should find a linux networking specific community for this one..
I have a strange issue that feels very familiar, like I've fixed it before, but I can't remember how.
I try to rtsp to security cam:
ffplay rtsp://user:password@192.168.19.137:554/h264Preview_01_main
And I get a no route:
Connection to tcp://192.168.19.137:554?timeout=0 failed: No route to host
rtsp://user:password@192.168.19.137:554/h264Preview_01_main: No route to host
Strange, I'm in the same subnet 192.168.19.129/24, and it worked a few days ago.
Check ping:
ping 192.168.19.137
PING 192.168.19.137 (192.168.19.137) 56(84) bytes of data.
64 bytes from 192.168.19.137: icmp_seq=1 ttl=64 time=5.69 ms
Of course.. So I run the command again;
ffplay rtsp://user:password@192.168.19.137:554/h264Preview_01_main
And now it works.
I could bandaid by crontabbing a ping every hour or something, but I would really like to know why I'm getting a 'no route' until I ping.
My routing table is pretty basic:
default via 192.168.19.1 dev enp4s0 proto dhcp src 192.168.19.129 metric 100
default via 192.168.19.1 dev enp4s0 proto dhcp src 192.168.19.129 metric 1002
172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
172.18.0.0/16 dev br-68c1e0344e27 proto kernel scope link src 172.18.0.1 linkdown
192.168.19.0/24 dev enp4s0 proto dhcp scope link src 192.168.19.129 metric 1002
192.168.19.1 dev enp4s0 proto dhcp scope link src 192.168.19.129 metric 1024
And I don't think I have any rules in firewall for LAN.
Any ideas?
You're viewing a single thread.
Why do you have two default routes?
The last line in your table also doesn't look right.
