similar to: telnet to serial connection?

Hello, ? I'm trying to configure my system such that I have a TCP port listening which will send all data it receives to a serial port. ie:?? tcp/2112? -->? /dev/ttyS0 My goal would be to be able to: Use netcat to create the listen and redirect to a serial port: ? $ nc -l 2112 > /dev/ttyS0 Then in another window, run minicom at /dev/ttyS0 Then in a 3rd window, ? $ telnet localhost

We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like to turn them into some sort of highly available nfs file server. Currently, I am familiar with DRBD and RHCS but I was curious what others might recommend in such a situation. I'm not sure how easily we could use RHCS in such a situation because we don't really have the advantage of shared storage in this setup.

I have to reinit a firewall that can only be done from its console port, and I do not have an XP system with Hyperterminal on it. So I went through the archive and learned that minicom could do the job for me. I installed it and went to configure it (minicom -s). I can set the speeds, but the challenge is selecting the serial device. I have a Serial-to-USB dongle, and when I connect it,

I am having problems when using a Dell PowerVault MD3000 with multipath from a Dell PowerEdge 1950. I have 2 cables connected and mount the partition on the DAS Array. I am using RHEL 4.4 with RHCS and a two node cluster. Only one node is "Active" at a time, it creates a mount to the partition, and if there is an issue RHCS will fence the device and then the other node will mount the

Hi all I am a newcomer of this ML. And I installed CentOS a couple of hours ago on my i386 box because it is said that CentOS is a community based binary distro of RHEL. Before that I used to use RH9(it is quite out of date for my newly upgraded PC) as my host environment to work on embedded systems. The installation procedure went smoothly and after that everything looked functional, however, I

Hi all I have a problem switch in our data centre, which is connected to a linux server via a serial cable. I know I can / could access the switch from my Windows PC back at the office, using hyperterm, but trying to access it using minicom just doesn't seem to work. I have changed the comms in minincom to use /dev/tty0 & the baud rate to 9600, yet I can't seem to connect with

Hello, I have a Soekris net4501, which I'm PXE booting using pxelinux. Everything seems to be working splendidly, except for the fact that I can't seem to make pxelinux understand use the net4501's serial console port correctly. The net4501 uses the serial console as its primary interface; I'm using a null modem cable and minicom to operate with it. At boot, its startup

I'm trying to make my little Asus eeePC 901 into a useful navigation tool that I can use on my boat. I'm running Ubuntu with the 2.6.24-21-eeepc kernel. For chart plotting I run SeaClear_2 (SC) under Wine. SC communicates as it should with my GPS via a Keyspan USB to serial dongle, both sending and receiving works with this device. I am also running the small app AISMon under Wine. This

Hi all, Somebody knows when RHCS for CentOS 4 will be out??? -- CL Martinez carlopmart {at} gmail {d0t} com

Hi, On a regular FC4 machine there are 76 device file for /dev/ttyS*. I tried running minicom on a Xen machine (domain 0) whose serial port is connected to a different machine (a machine with no VGA/Keyboard/Mouse). It gave the following error: minicom: WARNING: configuration file not found, using defaults Device /dev/ttyS1 access failed: No such file or directory. So I checked, and ls

Hi, I have to do some maintenance on a CentOS 7 proxy installed on a routerboard without a video card. The only way to access this machine directly is via Minicom and serial port. I'm using NetworkManager TUI (nmtui) to configure network interfaces, but Ncurses rendering in Minicom works in the sense that chickens fly and horses swim. What you get is a forest of question marks with a few

I need a terminal program, such as minicom, which I see is not part of my Strongbolt install of CentOS+BQ loaded on a RaQ 4 system. Does anyone know if a standard rpm for minicom should work or where to get a package that will provide minicom or other terminal program? Or, perhaps there is another terminal program installed in my system that I can look for? -- Robert

Hello fellows, I have a problem with a 2 node RHCS cluster (CentOS 4) where node 1 failed and node 2 became active. That happened already last year and due to holidays the customer didn't recognize it. The cluster is just a failover for Apache and has no shared storage space. Customer now saw the situation, tried to fix it by rebooting node 1, which then failed to come back up. As

I want to set up a cluster that is used for web hosting (RHCS cluster). Recently, I experimented with a 2 node cluster and was able to run it successfully. However, I have started facing some issues with Apache, which I had configured as a service using the Cluster configuration tool. To do this Apache needs a floating IP address. This address is in addition to the network interface IP address.

Hi all, When i do ''xm dmesg'' the last statement says "*** Serial input -> DOM0 (type ''CTRL-a'' three times to switch input to Xen)" (i have no clue what''s that supposed to mean??) But when i press ctrl-a three times at the serial console, nothing happens. Iam using minicom to connect to the serial port of xen machine. Once xen

I have two computers: both running CentOS 6.7, 64-bit, with kernel 2.6.32-573.12.1.el6.x86_64. One is a laptop with an 2 core Intel processor and the other is a desktop machine with a 4 core AMD processor. Both with selinux enabled. I have a USB serial port device (a RR-CirKits LCC-Buffer USB). On the desktop I am getting this error: sauron.deepsoft.com% sudo minicom Device /dev/ttyACM0
