Hello everyone, I recently bought a Riello IPG 600 UPS ( http://www.riello-ups.com/products/1-ups/39-iplug) to prevent hardware damage to my server in case of power outages (already lost two hard drives because of this) and I managed to successfully configure it with NUT version 2.7.4 available for Ubuntu 17.04: nut/zesty-updates,zesty-updates...

...ave been proposed. However, they have been hard to implement, because they require that the operating system maintains a high resolution timer, which could incur lots of overhead. In contrast, PSPacer employs an alternative simple and easy to implement scheme which adjusts the inter packet gap (IPG) to insert gap packets between outgoing packets. PSPacer can control the IPG precisely, by adjusting the amount of gap packets. The form of gap packet is the IEEE 802.3x PAUSE packet, therefore gap packets are discarded at a switch input port and real packets go through on keeping uniform interv...

Hi, I was wondering if anybody can help me. In the small data set below I would like to select the index which doesn't contain the letter 'N' in the variable 'letters'. How can I discard these rows when the letter has a different position everytime (but the same letter for the whole column)? index<-c(1,2,3) letters<-c("CCTTGGAA", "NNTTGGAAT",

Hi there! I am working a lot with VoIP in my company, so I thought to use linux bridge functionality together with tc to emulate delay, jitter, packet loss, duplication, reordering etc. for testing purposes in our lab against our VoIP products. I just recognized, that a basic bridge just with it''s minumum configuration of 2 network interfaces creates latency of approx. 5ms on very low
