remote profiling with SSH requires legacy key algorithms

Postby cyjb » Sat Jun 09, 2018 12:12 am

I'm running YourKit Java Profiler 2018.04-b71. When I try to connect to a remote machine, YourKit Java Profiler tells me it can't connect, and when I check the remote machine's auth log, I see a message like this:
Code: Select all
fatal: Unable to negotiate with port 60655: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1 [preauth]

I can modify the sshd config on the remote machine to accept one of these, but I believe they're all considered to be somewhat insecure. Are there plans to update the ssh library used by YourKit Java Profiler?

YourKit profiler runs on a JVM and uses its ssh libraries. On which Java version do you run the profiler? On what platform?

Could you please send the full profiler log to [email protected]
