People,
I get an error trying to ssh from a BasicLinux floppy booted 486 (I want
to sort out HD problems on the old Adaptec 1542 controlled SCSI drive
that has RH5.2 on it!) when trying to connect to my Fedora 25 x86_64
workstation. On the F25 machine in /var/log/secure I get lines like:
Mar 13 16:25:47 phil sshd[7562]: Unable to negotiate with 192.168.1.40
port 1034: no matching key exchange method found. Their offer:
diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1 [preauth]
On the BasLin terminal I get:

Any suggestions about how to fix this SSH problem?
Thanks,
