[SOLVED] Can't ssh into my laptop
Hi there,
I have been trying to deal with this issue for a few hours now and can't figure it out. I am having another unrelated issue on my laptop and I am trying to ssh into it from my arch desktop but I am unable to, actually I can't ping local machines either. I am able to ssh from another laptop into this one but my dekstop seems to not be seen on the network, I can't ping from it or receive pings from other devices. Using ethernet or wifi dongle the issue still persits. This isn't ssh issue per-se but rather than something in my network settings that isn't working as it should be.
I have tried nmap on wifi and ethernet and found 0 IP addresses.
I have generated new ssh keys too which didn't change anything.
This is the output of me trying to ssh:
ssh -vvv root@192.168.0.53
OpenSSH_8.7p1, OpenSSL 1.1.1l 24 Aug 2021

Re: [SOLVED] Can't ssh into my laptop
This isn't ssh issue per-se but rather than something in my network settings that isn't working as it should be.
So let's start there.
ip a; ip r
find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -fAnd finally please post a complete system journal ("sudo journalctl -b")

Re: [SOLVED] Can't ssh into my laptop
ix.io, but 45k lines is excessive - did you rise the debug level or so?
Edit: 1st link below
You've 3 NICs, enp6s0 has no carrier (no cable plugged), eno1 and wlp0s20u14 are connected to the same segment (192.168.0.0/24) in some(?) sort of failover(?) configuration.
Unless this is the explicit and deliberate cause of the problem, I'd suggest to only use one NIC for the moment and until the basic issues are sorted out.

I have a USB dongle connected to Wifi of the same router as my ethernet, this was a debug step, I forgot to remove it.
This is not an issue because the issue was present before. I will unplug the dongle now though.
The journal start from 2021-09-01 to 2021-09-26 hence the number of lines when I type in that command. You need this all? Also how would I decrease the length of the output for the specific parts you need?

Re: [SOLVED] Can't ssh into my laptop
The command is supposed to print the journal of the current boo ("-b"), did you not reboot since a month?
Another thing: your OP suggests a failure to ssh into 192.168.0.53, but that IP isn't attached to any NIC according to #3. Are you simply trying to connect to the wrong IP?

So I figured it out thanks for my friend. He was also having trouble sshing into his laptop on the same network but we were both able to ssh into each others pcs to test. Even if we're both connected to the same router through wifi and ethernet they're on a different layer it seems.
After I unplugged my ethernet from my pc and only had the wifi dongle I was able to finally SSH.
Thanks for the help tho seth, much love.
