TL;DR: LAN devices are reachable by everything except by slowroll.
I currently have a home network with two managed hosts with static IP addresses, each with two exposed LAN interfaces, say:
- Device 1 has:
192.168.1.20(eth0) and192.168.1.30(wlp3s0) - Device 2 has:
192.168.1.40(eth0) and192.168.1.50(wlp3s0)
The administration machine has the IP 192.168.1.15 which is also static.
Both administration machine and device 1 are connected to the same Wireless Repeater (Same SSID), device 2 is wired to the ISP modem/router.
Since all three devices have static IP addresses ideally they should be reachable normally. Which Slowroll isn’t doing.
I can access all three hosts from other devices inside the LAN, with Slowroll this isn’t the case, trying to access this machine via SSH returns a:
ssh: connect to host 192.168.1.20 port 22: Connection timed out
# Using the second interface doesn't help
ssh: connect to host 192.168.1.20 port 22: Connection timed out
Trying to connect using an android SSH client (inside the same connected SSID) does return an SSH session.
For some reason it appears that OpenSUSE (in the control node) randomly decided to stop recognizing all other LAN hosts, nmap -T4 -A -v 192.168.1.0/24 shows the administration machine to be “alone” in the network:
Nmap scan report for 192.168.1.20 [host down]
...
Nmap scan report for 192.168.1.30 [host down]
...
Nmap scan report for 192.168.1.40 [host down]
...
Nmap scan report for 192.168.1.50 [host down]
...
Scanning 192.168.1.15 [1000 ports] <-- localhost in this case
Nmap done: 256 IP addresses (1 host up) scanned in 5.52 seconds
I tested communication between devices and the Slowroll admin machine is the only one who gets timeout on all attempted host communications.
Does anyone have any idea what could be happening? Could this be something introduced by an update? I would love to blame this on the repeater, but the second host (192.168.1.40) which is also wired to the same network, can access and be accessed by other hosts.
