I have had several network testers here now for measure the connections in LAN between server rooms terminations to outtakes in the building. After a year or so they fail, Tired of sending back to seller and get new. I know there are better quality to buy rather them I have tried, but expencive they are.
I have to small old notebooks that i could install a linux os on both, and have each one in each end of the cable. But I can not find a suitable program for measuring if all pairs are intact. Iperf I have tried, and gives of course a good indication if the cable should be defect, but I would like to have a program with server/client that can indicate the condition of all pairs. Anyone who have any idea for such a program?
