I have a problem with SSH. I can not ssh into a server because of DH GEX group out of range
My ssh version:
OpenSSH_7.2p2 Ubuntu-4ubuntu2.4, OpenSSL 1.0.2g 1 Mar 2016
I tried to ssh into a server that has host key algorithms:
c-sha1-96-etm@openssh.com,hmac-md5-96-etm@openssh.com,hmac-md5,hmac-sha1,umac-64 @openssh.com,umac-128@openssh.com,hmac-sha2-256,hmac-sha2-512,hmac-ripemd160,hma c-ripemd160@openssh.com,hmac-sha1-96,hmac-md5-96 mac algo SC: hmac-md5-etm@openssh.com,hmac-sha1-etm@openssh.com,umac-64-etm@open ssh.com,umac-128-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm @openssh.com,hmac-ripemd160-etm@openssh.com,hmac-sha1-96-etm@openssh.com,hmac-md 5-96-etm@openssh.com,hmac-md5,hmac-sha1,umac-64@openssh.com,umac-128@openssh.com ,hmac-sha2-256,hmac-sha2-512,hmac-ripemd160,hmac-ripemd160@openssh.com,hmac-sha1

And this is my ssh debug:
