I have really imagine myself managing Solaris 10, I really want to go back to GNU/Linux, I can’t please. ?
I have been learning Solaris for some months now and decided to get back to working on the terminal and trying to ssh into the server but was having this error.
Unable to negotiate with 192.168.111.129 port 22: no matching key exchange method found. Their offer: gss-group1-sha1-toWM5Slw5Ew8Mqkay+al2g==,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
SSH Configuration In Solaris
You have to check if the SSH Daemon is running on your system first, which by default it runs but do check that again.
# /usr/bin/svcs ssh
And it shows the STATE either online or disabled, But incase it is disable enable it with the following command.
# svcadm enable ssh or # svcadm enable network/ssh
Configuring SSH Config File
vi /etc/ssh/sshd_config
From your configurations of SSH of config file, I enabled the following.
PermitRootLogin yes PasswordAuthentication yes
And then save and restart the sshd daemon with,
Note: I permit root login and also use PasswordAuthentication for some reasons, But you need to disable both in a production or enterprise server for security reasons.
# svcadmn restart ssh or # svcadmn restart network/ssh
SSH Into Your Oracle Solaris
I was having an issue with the Cipher key exchange method in other to fix this.
ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c 3des-cbc [email protected]
Just change your username and password to what you need to login into.
That’s all, If you need an explanation on the options of the ssh used, let me know.
