Our host have updated their algorithms and removed outdated ones,
and now, whenever I try to access any site on the host, I get the error saying:
"Algorithm negotiation fail". (RSEG1066)
I am running RSE 3.7.100 with eclipse Photon.
Do you have an update comming out?
Or is there another way of getting it to work?
Really enjoy this IDE, but working on remotes systems are a must for us, and I don't intend to switch host on 20+ websites :-D
Kind regards
- Jesper

Hello Jesper,
RSE / Eclipse uses JSch for the SSH communication. As per the JSch homepage http://www.jcraft.com/jsch/ , the following ciphers should be supported:
Key exchange: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521
Cipher: blowfish-cbc,3des-cbc,aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-ctr,arcfour,arcfour128,arcfour256
Please check if any of these should be compatible with your host. You could also try checking with a local command-line ssh to see what your host reports (ssh -vvv yourhost).
I'm afraid that I won't be able to help beyond these initial hints. RSE is not really maintained any more. You might try the mailing list https://accounts.eclipse.org/mailing-list/tm-dev but don't expect timely replies.
Good luck,
Martin

I am not sure why -
I followed your hint, and looked at what my host reported through the command-line, and it all seemed fine - So I couldn't understand it.
I installed netbeans - (Which had the same problem)
So I updated my JDK, which seems to have fixed both eclipse and netbeans for me.
It is working fine now - I really love that RSE/eclipse can work directly on the servers, instead of having to download and create projects for all of my sites.
(something that PHPstorm and netbeans could learn form)
Well thank you for the tip Martin.
