Having problem with remote login on Ubuntu after being updated to 15.04
I updated my server from 14.1 to 15.04 and I having issues logging in with one of my IDE's. I kept getting this errror,
establishing sftp connection failed no suitable key exchange algorithm could be agreed
I found this page with a solution https://nikinuryadin.wordpress.com/2015/05/19/aptana-studio-3-sftp-key-exchange/
It says to add this line to my /etc/ssh/sshd_config file
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,email@example.com,firstname.lastname@example.org,email@example.com,blowfish-cbc,aes128-cbc,3des-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc KexAlgorithmsfirstname.lastname@example.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
My question is, will this weaken my security or cause any major security risks by adding these ciphers?
