i am using debian, i used to ssh to a machine
172.21.128.61 inside my local network a few weeks ago, probably after the updates i cannot ssh into that machine again,
ssh email@example.com shows:
ssh: connect to host 172.21.128.61 port 22: No route to host
so i tried pinging the machine
ping 172.21.128.61 shows:
PING 172.21.128.61 (172.21.128.61) 56(84) bytes of data. From 172.21.0.1 icmp_seq=1 Destination Host Unreachable From 172.21.0.1 icmp_seq=2 Destination Host Unreachable From 172.21.0.1 icmp_seq=3 Destination Host Unreachable ^C --- 172.21.128.61 ping statistics --- 6 packets transmitted, 0 received, +3 errors, 100% packet loss, time 5128ms pipe 4
Another windows machine in the same network is able to ssh into the machine
172.21.128.61 as well as getting the response on pinging.
i can ssh into
firstname.lastname@example.org which is a demo ssh server (ofc not local)
I think i may have messed up my ssh client for local networks.
My machine's local IP:
ip addr returns:
2: wlp0s20f3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 14:f6:d8:f3:85:81 brd ff:ff:ff:ff:ff:ff inet 22.214.171.124/22 brd 126.96.36.199 scope global dynamic noprefixroute wlp0s20f3 valid_lft 12379sec preferred_lft 12379sec inet6 fe80::2cfd:51da:c35:978b/64 scope link noprefixroute valid_lft forever preferred_lft forever
traceroute 172.21.128.61on both 188.8.131.52 and the other system, and edit the question to add the results?
