When I try to connect to my switch I get this error
$ ssh cisco@192.168.7.203
Unable to negotiate with 192.168.7.203 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1
And I just did a factory default on this box
System Description: SG300-52 52-Port Gigabit Managed Switch
Firmware Version (Active Image): 1.4.11.5
Boot Version: 1.3.5.06
Configured it like this
configure
interface vlan 1
ip address 192.168.7.203 255.255.255.0
no ip address dhcp
ip default-gateway 192.168.7.1
end
config
ip ssh server
ip ssh-client server authentication
ip ssh-client source-interface vlan 1
end
copy running-config startup-config
reload
What am I missing?
This works, but I would like to configure the switch properly
ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c aes256-ctr cisco@192.168.7.203
