RS-232 serial to ethernet

2019-04-08 Thread LÉVAI Dániel
Hi misc@! I was wondering if I could use some budget solution to access my OpenBSD machine via its serial console over the network, and I stumbled upon this piece of hardware: [1] [2] [3] (the same device "USR-TCP232-302", I'm just not sure which one will be up at the time someone looks at them)

Daniel, Ethernet to serial is normally done using ppp [1]. Why add unneeded hardware. Do you have RJ45 or RS232 on the OpenBSD machine already? Joseph [1] http://man.openbsd.org/ppp ‐‐‐ Original Message ‐‐‐ On Tuesday, April 9, 2019 12:04 AM, LÉVAI Dániel wrote: > Hi misc@! > > I

I have a somewhat similar device and works without issues. However, it has a serious backdraw: it provides no way of securing the comms channel: any TCP/UDP is open text. Should you need to use such a device in the wild, take that into account. Regards! El lun., 8 abr. 2019 a las 18:07, LÉVAI

Hi, I guess you're hitting 2 bottlenecks: the CPU performance for iperf and HDD performance for scp. Check how much CPU is consumed during iperf transfer and try scp'ing something not from/to HDD, e.g. /dev/zero. I've seen extremely slow HDD performance in OpenBSD, like 12x slower than on

I have one of these, but I really only use it to connect the old VIC-20 to BBS systems. It works alright, but it's a bit funky in it's implementation.  As others have said, it's completely plaintext; everything is sent in the clear.   You'd be telnetting (not ssh) into it. How much do you trust
