Unable to connect to devuan laptop server on local network

nuclearkev · 2025-07-02 19:27:26

Hi all,

I've run into a issue with my current Devuan install on my laptop. When trying to use a program called "qrcp" I found that I was unable to connect to the server that was created in order to do the file transfer. I did a little testing and if I spin up an nginx server, I have the same issue. I also found that I am unable to ping the address of the laptop as well. After even more digging I found that there were certain machines that I was unable to ping _from_ the devuan laptop (making the request while on the laptop pinging outward) namely my actual home server, my phone, and my TVs but I was able to ping everything else.

I've checked for firewalls, iptables, subnet issues, tried joining to different wifis, etc. but nothing seems to fix this issue. Does anyone have any idea what could be causing this?

PS: I do have internet connection although I recently broke NetworkManager in the process of debugging... xD

Does the router isolate between wireless hosts and wired hosts?

nuclearkev · 2025-07-03 14:13:12

Nope, if I boot into a liveCD I can ping and ssh to the server without a problem. I haven't tried starting up a server on the livecd, however.

Here are a few thing to check:

How are the systems connected to your network?
If any systems are connected wirelessly check they are connected to *your* router, not one belonging to a neightbour. That has been known.
If the laptop also has an ethernet port try connecting it to your router with an ethernet cable. Does that change the symptoms?

What are the symptoms of ping not working? Replace target with the name of the system you are trying to reach below (server, laptop, etc):
host target - does this return the servers IP address?
traceroute target - how many hops away is the server?
ping target - what does it say?
ssh -v target - some systems don't respond to ping but will allow a ssh connection. The -v will make ssh show how far it gets.

I hope that gives you some help.

$ ping 192.168.1.4
PING 192.168.1.4 (192.168.1.4) 56(84) bytes of data.

`ping` never stops...

$ ssh -v samba@192.168.1.4
OpenSSH_9.2p1 Debian-2+deb12u6, OpenSSL 3.0.16 11 Feb 2025

ssh: connect to host 192.168.1.4 port 22: Connection timed out

When I run those on a computer that can connect to the server obvious ping gets a response in like 12ms, traceroute returns something immediately, and ssh asks for the password. The only one that is the same is when I use `host'. I get the same response.

Yes it sounds like the installation (not liveCD) has something wrong.

Does it have a firewall? e.g. does iptables-save report something; (or if you use nftables there would be a similar command among its programs). And use ip6tables-save for ipv6 rules. (I'm not sure about the nftables commands)

Is the interface up? ifconfig wlan0 would be the easiest, if you have net-tools installed. An you'd also check with ip link show dev wlan0 and ip address show dev wlan0. The ip command comes from the iproute2 package.

Is there a default route? ip route show ... and checking ipv6: ip -6 route show

Hmm but if understand right, the laptop does have other internet access... anyhow, please include the outputs of those commands and we'll see if there's something to see there.

Yeah; almost all the iptables rules concerns accepting packets in circumstances, which are kind of useless rules when policy is "accept". However since they don't interfere they can be ignored. And in any case they shouldn't concern wlan0 traffic.

But that virtbr0 bridge might have networking impact. What's your output of brctl show? And ifconfig virtbr0?

I suppose the problem(s) you talk about concern the main host and network 192.168.1.0/24; not any qemu virtual machine?

nuclearkev · Yesterday 13:31:02

Yeah, no virtual machines involved.

ifconfig virtbr0:

# ifconfig virtbr0
virtbr0: error fetching interface information: Device not found

brctl show:

# brctl show
bridge name     bridge id               STP enabled     interfaces
virbr0          8000.5254001b4e3b       yes

nuclearkev · Yesterday 13:32:31

Oddly enough, if I attempt to remove the bridge with brctl delbr it claims that the bridge doesn't exist...

ralph.ronnquist · Yesterday 14:23:10

I misspelled; should be ifconfig virbr0, but I think the bridge is ok since it doesn't have any interfaces. So now it's getting mysterious.

Do you have anything from ebtables-save
Does ping -n 192.168.1.1 work fine?
Check the router's host list for shared ethernet address 2c:9c:58:29:10:6f

ebtables-save returns nothing.

There are no shared ethernet addresses on my router from what I can tell,

To repeat some of my questions you didn't answer:

How are the systems connected to your network? Please answer for both the laptop and the server,
If any systems are connected wirelessly check they are connected to *your* router, not one belonging to a neightbour. That has been known.
If the laptop also has an ethernet port try connecting it to your router with an ethernet cable. Does that change the symptoms?

nuclearkev · Yesterday 16:26:42

How are the systems connected to your network? Please answer for both the laptop and the server,

17 devices are on the network. The laptop and server are on the same network. The home server doesn't currently have any active connections as it's used for backups and streaming mostly. Neither are being used at the moment.

If any systems are connected wirelessly check they are connected to *your* router, not one belonging to a neightbour. That has been known.

Yes, they're on the same network. In other words, I can ping most devices on the network. Only the few mentioned can't be ping by the laptop only. From what I can tell, no one on the network can ping the laptop either.

If the laptop also has an ethernet port try connecting it to your router with an ethernet cable.

Sadly, it doesn't. I don't have a USB-ethernet cable either.

Sorry for missing these earlier!

EDIT: missed some info

As you may know all (almost) network messaging comes in pairs with outbound packets getting inbound responses. I use tcpdump to look at that to show what happens on an interface, like:

tcpdump -n -i wlan0

to see packets in to and out from wlan0 without attempting "reverse dns" on them (i.e. see IP addresses rather than domain names).

You do that in one terminal while using an other terminal for trying things like ping. The best is if you can do the same on the target host, to see where the messages hold-up may be. Note that for ipv4 it is essential that "arp" messaging move freely; the hosts use that so as to learn the ethernet addresses of LAN devices. All networking is carried by the link-level LAN connectivity, which uses the ethernet addresses or broadcasts (i.e. address ff:ff:ff:ff:ff:ff plus the broadcast flag bit set).

In your case, I do suspect your router. I think that most routers have "broadcast groups" where they only forward broadcast messages to interfaces within the group of the interface where the messages come in. Which router do you have -- brand and version "number"? (with that we can probably find its instruction book on the Internet)

Routers may also have limitations on number of connected devices.

GlennW · Yesterday 22:35:14

hi, as a side - note, with "ping" use -c (n) for the number of times to "ping".

I generally use,

ping -c 4

All the best.

The router is a Netgear ORBI32, firmware version 7.2.7.15_5.1.16. I don't really think it's the router because the IP of the laptop has changed over the many days I've looked into this. Originally I was 192.168.1.20, then 6, and now 17. Unless there is something doing it based on MAC address.

EDIT: the server's address is 192.168.1.4

EDIT 2: The number of connected devices isn't the problem either. If I boot into a liveCD of another distro (in my case I used gentoo), I can ping the server and I can be pinged no issue.
