[Swift-user] Error with SSH and SSH-CL

[Yadu Nand]

Hi Justin,

Could you send me a tarball of the configs and the log files generated ?

Meanwhile, could you try the configs from the test-suite for the MCS
systems ?
https://github.com/swift-lang/swift-k/tree/release-0.95-swift/tests/sites/mcs
You would need the sites.template.xml, swift.properties and
tc.template.data.

Thanks,
Yadu
