Alle, After upgrading from 6.4 to 6.5, our serial console configuration non longer work. We have the following upstart file: [cwfox at hilo ~]$ cat /etc/init/ttyS0.conf # ttyS0 - agetty # # This service maintains a agetty on ttyS0. stop on runlevel [S016] start on runlevel [23] respawn exec agetty -h -L -w /dev/ttyS0 115200 vt100 [cwfox at hilo ~]$ And the following in /etc/securetty:

I am having trouble sending sysrq commands over USB serial, and I'm not sure what else to check. I have two identical machines, each with usb-to-serial adapters, joined by a null modem adapter. One runs an agetty, the other minicom. I can log in over the agetty as a user and it works as expected, until I try to send a sysrq. To send a break in minicom, I type [Ctrl]+[a] then [f]. Then I

Hello, I''ve got a problem to get a serial output on grub, xen, linux-xen0 and getty. The serial works fine with grub, xen and linux-xen0, but I''m unable to start a console, where I''m able to login. I dont''t get any output. If I change only the getty from ttyS0 to ttyS1 than I''m able to login.. At the attachment you can see what I see through a serial,

Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

Hello All I just recently adopted a server with Gentoo/Xen as domain0 server with several domainUs attached to it. Please forgive my xen-noobness, but I was hoping that someone can help me out. These images have not been updated in a long time, and I''m trying to get all the domainUs updated with their appropriate services patches, etc. I''m currently working on one Gentoo

Hi, This morning I had some failed calls. On the console (and in the log) I saw the error "Unable to allocate channel structure". Before I restarted the process, I checked it's memory usage in ps and glanced at my free memory in top. Asterisk was using a normal ammount of memory, about 40M. I don't think this was a system limit. This was running Asterisk v1.0.2. Below is

I have a situation where gnome console does not handle vt102 escape sequences properly and therefor need to employ xterm instead. When I run xterm from a gnome terminal window I am presented with an extremely small terminal window employing an almost unreadably small font. I have attempted to set the font size using xrdb and a custom .Xresources file. I can change the colour scheme. I can

I decided to upgrade from openSuse 10.2 to openSuse 10.3. I installed xen things, but when I boot using xen option the system is blocked. It appears the green window, with little suse logo in the middle, and mouse cursor, but the system crashes. My computer is a Pentium 4 1,5 GHz, 512 MB of RAM. I attached "diff boot.msg boot.omsg" (as diff opensuse-normal-kernel opensuse-xen-kernel)

I've been installing CentOS via PXE and using a serial console interface. The installation works great. I notice that during the install process, the following line gets added automatically to /etc/inittab: co:2345:respawn:/sbin/agetty ttyS0 9600 vt100-nav Which package does this? Is it kudzu?

Hi, I need to add one line to /etc/securetty, say it needs to be ttyS1. Do not add it if ttyS1 already exists in file /etc/securetty. How to achieve this using puppet module in puppet 2.5? This file is different than the other examples using augeas, this one only has value per line, not name-val pair.

Hello, I''m enjoying my Xen quest very much thus far. Q: How does one handle the situation of multiple root users on dom0 trying to `xm console'' to the same guest? I was unable to use the virtual console at all until I added a line to inittab for agetty to spawn on xvc0. Now I''m not sure of an elegant solution for supporting multiple consoles (possible?), or even

Hi, On a regular FC4 machine there are 76 device file for /dev/ttyS*.
