I submitted some comments for BUG #18, but forgot to cc this list. Let me know if I shouldn't cc the list. Bugzilla Bug 18 Using ssh -f -L bombs on SCO Openserver 5.0.5 ------- Additional Comments From Sam Vaughan 2001-12-13 08:17 ------- This seems to be fixed in Openserver 5.0.6. The above command runs as expected. So something has changed between 5.0.5 and 5.0.6 in the way select has been implemented in SCO. The only thing I found, so far, is in patch 5.0.6a for 5.0.6 systems. "As of Release Supplement 506A for OpenServer Release 5.0.6, a subset of APIs that use the kernel clock have been modified to utilize the high-precision clock. These are: select(S) has microsecond precision, adjusted for kernel entry and exit times, time-sharing delays, and so forth." Could this be the change? I traced the error on 5.0.5 to the select statement in the function client_wait_until_can_do_something in file clientloop.c When I get more time, I will look into this further.
