I'm having trouble with SSH sessions between two laptops on my network,
A is a laptop I bought recently.
B is the laptop it replaced.
When I purchased
A, I cloned
B's hard drive.
A thus has the name that
B used to have, and I gave
B a new name by editing
/etc/hostname and the name of
I built new ssh host keys on
B and also a new ssh key for my user account there.
On a separate device, I run DHCP and DNS servers, and I reserve addresses for most of my devices.
B's Wi-Fi interface had a reservation for
x.x.x.10. I changed
B's reservation to
x.x.x.23 and gave the
.10 address to
A's Wi-Fi interface.
The problem I'm having is that whenever I try to connect via ssh from
B or from
A, the SSH session freezes after all the handshaking and negotiating.
I have no problem ssh-ing to or from either of these machines and any other device on the network. But on
B, I've even installed Windows (fresh) as a dual boot OS, and from Cygwin, when I try to ssh to
A, I have the same problem.
I've cleared the ARP cache on these machines and every other one on my network, but to no avail. I have no trouble running
iperf between the two machines, and I can host a simple web application on one and view it on the other. I don't know what's going on with SSH.
It has to have something to do with the Wi-Fi connection, though, because if I connect the two laptops together with an Ethernet cable and give them static IP addresses, I have no problem with SSH over that interface.
I shut down the sshd daemon on
B and ran this:
sudo /usr/bin/sshd -ddd 2>daemon.log
A, I ran this:
ssh -vvv B 2>client.log
