Redhat/CentOS #2

Open adorosario opened 14 years ago

adorosario commented 14 years ago

Any luck with the redhat system? I tried removing the -q0 from nc and that took me a little further.

However, there seem to be other problems with the ssh'ing.

I run into the nc -q0 problem as well. I'm using Fedora17. What's the meaning of the -q0 option? I wonder if there is another option can do the same thing as -q0 in Fedora's nc.

erikfrey commented 11 years ago

-q0 instructs netcat to close immediately after reading EOF from stdin.

It may not be necessary at all in Fedora, but I don't have a way of testing. If you can get br to run the example and performance tests in Fedora, with different arguments to netcat, I'll add a switch to conditionally use those args.

i get the error message "nc: invalid option -- 'q'" when run it in centos6.4.

Try installing nc6 and using it instead of nc in the br script. That solved the problem for me.
