This is the patch from Amos Waterland for the xenconsole to use /dev/xvc0 instead of taking over ttys. I''ve fixed a few places which needed to check for XVC mode in addition to serial mode. Also, until LANANA responds with an official minor, I''ve adjusted it to use char 250/187 (in the experimental range) as opposed to 204/187. (Should be identical to this patch from last time)...

On FreeBSD 4.x with HAVE_LOGIN_CAP defined the OpenSSH daemon doesn't properly follow standards. As stated in man 5 login.conf and the process followed by /usr/bin/login, "The ttys.allow and ttys.deny entries contain a comma-separated list of tty devices (without the /dev/ prefix) that a user in a class may use to access the system, and/or a list of ttygroups (See getttyent(3) and ttys(5) for information on ttygroups)." It appears that the OpenSSH Daemon...

Fix the polling section of the hvc driver to use the global "last_hvc" variable, rather than the ttys.

Hi all, I have a question on /etc/inittab for DomU booted with xencons parameter. I saw the following error messages when I appended xencons=ttyS to DomU boot option.

...t three file descriptors are something like socket: [460]. The issue on this system is a number of tty related functions fail, greatly impairing my ability to use all but the simplest terminal programs. What is wrong? What must I do to enable programs run over ssh (such as bash) to get real pseudo-ttys and not simple sockets? Thank you for your time, James Steven Supancic III

I have the following line in /etc/ttys: ttyv8 "/usr/local/bin/kdm -nodaemon" xterm on insecure Because of X misconfiguration it constantly crashed, so: kdm-bin[1178]: Unable to fire up local display :0; disabling. So I fix xorg.conf, then I change on => off in ttys, then I do kill -1 1, and X gets started! Seems il...

Hi, I am running nut with megatec driver accessing ttyS0 as user nut on "standard" kernel (gentoo-sources). It works fine. However, I just built a hardened kernel on a new gentoo machine and have no experience with it. NUT (upsdrv) is failing because it says it doesn't have permission to access ttyS0 even though nut is within the appropri...

...stem from CDs but they were not. I have found various resources on the web and from them uncovered the setserial utility. What I need from somebody is guidance on how to use this utility to properly configure the ports.

I'm trying to work out how to set up a custom udev rule to override permissions on serial ports (/dev/ttyS* and /dev/ttyUSB*) on CentOS 5.3 The default rule, in /etc/udev/rules.d/50-udev.rules has the line: KERNEL=="tty[A-Z]*", NAME="%k", GROUP="uucp", MODE="0660" and I would like the mode to be 0666 Various docs on web say that you shouldn't ch...

I am a 62 year old beginner in Ubuntu. Thanks for any help, guidance, suggestions on this problem! I have used commands like the following to be certain that I have an active com port: dmesg | grep ttyS rm com1 ln -s /dev/ttyS0 com1 So I suspect the solution lies somewhere in WINE. If all else fails I will get a USB to SERIAL converter cable and try that. My wife has an Abbott Labs Freestyle Lite Glucose meter which uploads to a program called COPILOT via RS232. I was only able to get it to wor...

Hi, I would like to log all keyboard activities in all ttys in my FreeBSD 5.2 box. Is there anyway to do it? I read the watch man page and it seems like I should run watch with tty as many times as number of ttys. Am I right? Also is it possible to do the log in invisible way? The main reason is to log all commands typed in shell and tty and send the log t...

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 direct...

While all ?real? ttys may support TIOCGPGRP, /dev/console doesn?t; using TCGETS here allows Linux booted with init=/bin/mksh-static to have working interactive command line (PS1, editing, etc).

...e followed the code in pty_make_controlling_tty and it seems to go as follows: 1. Starts with a controlling tty. 2. setsid works, no controlling tty. 3. open of tty works, however it doesn't become the controlling tty. 4. open of /dev/tty fails. I don't have a huge experience of pseudo ttys or controlling ttys but it looks to me like point 3 fails because there is already an open file handle pointing to the same device. As an aside, Dynix has a function called fvhangup (virtually hangup the specified controlling terminal) but if I insert a call to this then all slave terminals are h...

> ssh has to set NONBLOCK otherwise it can, well, block - there's > no way for ssh to know a priori how much data it can write to a fd. I don't know anything about how ssh is structured, but I think it must be a bit more complicated than that. Ssh only sets O_NONBLOCK on an fd if isatty(fd) returns false, so it's able to function with blocking input and output if the relevant

Hello xen-users ! I am coming for help concerning the just released 4.0 version. Install has worked rather well on my Debian Lenny. I have just had a few bugs for which I have found the answer looking around on this list. I have created a Debian Lenny domU which boots up just fine. The only problem is that I am unable to get a console prompt when using "xm console nameofdomU". I do see

I get no data from reader. Even cat /dev/ttyS0 does not work anymore afterwards. I thinks it's because as soon as application opens it via wine some tty flags change: (P...
