Hi evsar3,

I'm having the same problem. I can connect using SiriKali via the mount options field which is free text so adding KexAlgorithms isn't a problem.

KexAlgorithms is not listed as a custom command line params and I can't find any way to set it when using sshfs-win manager.

Can you add KexAlgorithms to the list of custom command line params? Or provide an option to name params that aren't listed?

Thanks Chris

I've solved this issue by using the custom command line param ssh_command with value ssh -o StrictHostKeyChecking=no -o ServerAliveInterval=15 -o ServerAliveCountMax=3 -o KexAlgorithms=diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

With the exception of idmap, create_file_umask, create_dir_umask and umask (these were also set via custom command line params), the options above were copied from the SiriKali Mount Options.
