I'll spend some time debugging with this in mind. Basically I as understand it now the connection is via std in/out over ssh and any extraneous output from the shell can break things. What I'm currently seeing is the following: chlr11723> fossil clone ssh://host.com/tmp/mrwellan/blah/fossils/test.fossiltest.fossil ssh -e none -T host.com ssh: Reflection for Secure IT 6.1.2.1 (build 3005) on x86_64-suse-linux-gnu (64-bit) fossil: ssh connection failed: [] But "ssh host.com ls" works fine.
