[Swift-devel] MODIS freezes on Midway

[Ketan Maheshwari]

Yadu,

netcat/nc has been helpful in the past resolving network/port connectivity
issues. I tried to write to midway port 50000 from beagle which worked:

on midway:

$ nc -l 50000

on beagle:

$ netcat 128.135.112.71 50000
hello from beagle

Gives on midway:
$ nc -l 50000
hello from beagle

Hope this helps with debugging.
