I have someone wanting to connect to the serial management port of a switch from a PC running CentOS6. The management port on the switch is apparently baud 9600, 8 data bits, 1 stop bit & no parity They have plugged in a cable to connect and the output from lsusb is:-
Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

Bus 001 Device 004: ID 03f0:094a Hewlett-Packard Optical Mouse [672662-001]
lsusb -vs 1:2 shows the device in question and gives me:-

The devices I find with usb in the name are these:-
Assuming that I have to create a symbolic link as /dev/modem, what do I point it at? I've tried a few such as /dev/ttyUSB0, /dev/bus/usb/001/002 and the like, but I'm not sure how to test I've got anything right.
It's been suggested that the tool to use is minicom and I've set up the connect speed and negotiation as I've been told the serial port on the switch will expect but no output (not even rubbish) on screen. It's wanting a devices called /dev/modem which is why I presume i just need to create the link.
It's all a bit odd because it is a remote site, but the network team need to get on the serial management port of one of the other switches. They are hoping we can save a journey.
Am I even using the right approach with the right tools? For all I know, minicom might be offering dial-in to my server rather than driving a serial line the other way.
I'm informed it's an HP 2620 switch with a Prolific USB to serial adapter. I've not been to the site, so I'm taking it on trust or the network chap.
He's also suggested using ser2net but I've not got this RPM available to the site to install. We don't allow our remote sites to connect to public package sites, just our internal version. I would have to to package it locally, but that's a lot of work and I'm pretty unfamiliar with that process.
Could you not connect the serial from the switch to a serial port on an old PC piece of kit (running say, Windows 7), and test access from there with a terminal emulator eg, hyperterminal. Then set up remote desktop protocol (rdp) on the machine to allow remote access from the corporate network.
That may not be suitable for you but I've done similar a few times.
HI,
Does anyone installed a GPS from his Serial port to an IBM Server serial port with AIX 5.X
I would like the rs232 configuration you used on the GPS, and the ttys configuration from your server.
Thanks in advance !!! (8 Replies)
