2016-11-21ssh.py: add flag to keep stdin openRoss Brattain1-0/+19
For some VNFs we may want to send periodic commands, for example to print statistics, but otherwise not write anything for long periods of time. Currently when we can no longer read from stdin we close it. A workaround is to constantly spam stdin with newlines to keep forcing stdin open. We don't want to have to do this, so add an enable flag to keep stdin open. If the caller wants to close stdin at some point it can.

2016-08-12[Yardstick-233]latency measurment by using pktgen-dpdkwu.zhihui1-0/+9
VM A runs pktgen-dpdk as a traffic generator and is connected back-to-back with VM B running testpmd for forwarding packets. 1. use linux expect to fetch the latency statics data. 2. fetch 10 samples of latency and calculate avg_latency. 3. use screen to keep test scripts running in the background. 4. add a function send_command() for screen in ssh.py JIRA:YARDSTICK-233 Change-Id: I90ae64b3d198c79f159275ae35715eb284f05080 Signed-off-by: wu.zhihui <wu.zhihui1@zte.com.cn>
2015-08-20Add unit test for sshKristian Hunt1-0/+285
Unit test file for ssh.py originates from rally. It is modified to be consistent with the ssh module used in yardstick - some tests for missing functionality are removed and naming convention is changed (ssh in yardstick vs sshutils in rally). Running of unittest from run_test.sh is NOT enabled. JIRA:- Change-Id: I3ea554e3fbe6f1f906778f88ddd859424331c8df Signed-off-by: Kristian Hunt <kristian.hunt@gmail.com>
