ncal(1) prints control sequences on stdout if stdout is not a tty
Hi list, being the maintainer of www/nanoblogger, which uses cal(1) to generate the blog calendar, I noticed that ncal(1), and therefore cal(1), prints control sequences to stdout in order to highlight the current date. This scrambles the calendar generated by nanoblogger. I fixed this issue in the port but talking to one of the folks of our local unix user group I was asked why I am not fixing this in ncal(1) as the sane behaviour would be to omit control sequences if stdout is not a tty. Thinking about that I decided to create a patch: http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/158580 I just wanted to ask you fellow FreeBSD users what you think about this issue as feedback in PRs tends to be slow.

vidcontrol / vesa mode regression in 8.1-RELEASE
Hi list. I just upgraded my laptop to FreeBSD 8.1 and this time it's the first time I actually have a regression: I can't switch my console to high resolution using vidcontrol or allscreen_flags in rc.conf. My kernel configuration contains VESA and SC_PIXEL_MODE: t...@sushi [/usr/src/sys/i386/conf] > egrep "(SC_|VESA)" SUSHI options VESA options SC_PIXEL_MODE With basically the same kernelconfig I could use the following call in FreeBSD 8.0 to switch my console to a higher resolution: vidcontrol MODE_279 This no longer works. The display gets black and I can't see anything. Nonetheless I can enter commands which are executed. I just don't get any visual feedback. So I can at least reboot after experimenting with vidcontrol ;) I tried several modes and it seems it's the VESA modes which are misbehaving. I played with hint.sc.0.vesa_mode which is mentioned in the release notes but I honestly don't know how to use it. Any hints on this issue? I will provide further information if you tell me what you need. Thanks in advance, Tobias pgpiGdwo8einQ.pgp Description: PGP signature

[OT] C programming question: reopen stdin
Hi all. I'm having a little trouble solving a specific problem in C. I want to write a filter which reads data from stdin. After reading the user should be able to interact with the program via stdin. This means I have to reopen stdin but I don't know how to do this. I tried to solve this using dup() and dup2() but without success. You can have a look at my first experiment here: http://gist.github.com/95320 I guess the code and the contained comments show what I'm trying to achieve. Although this is off-topic on this list I hope someone with more knowledge in C may steer me into the right direction. Sorry for the noise and thanks for reading.

[perl] sysopen(CD, "/dev/cd0", O_RDONLY | O_NONBLOCK) fails
Hi all. I have a perl script which seems to work fine under Linux but fails on FreeBSD. The Problem is the line: sysopen(CD, "/dev/cd0", O_RDONLY | O_NONBLOCK) After this line the following evaluates to true: $! eq "No such file or directory." /dev/cd0 is readable and writable for me. I rebooted multiple times and tried with and without atapicam. sysopen(CD, "/dev/acd0", O_RDONLY | O_NONBLOCK) fails either. So what's up here? Is sysopen a linuxism? Any help is greatly appreciated.

Re: Jailing net/skype
For the archive: I finally got skype working in a jailed environment. The hardest part was to define the ports needed using trial and error. Here are the leaf ports installed in my jail: ===>>> skype-2.0.0.72,1 ===>>> xauth-1.0.2 ===>>> xorg-fonts-100dpi-7.3 ===>>> xorg-fonts-75dpi-7.3 ===>>> xorg-fonts-cyrillic-7.3 ===>>> xorg-fonts-miscbitmaps-7.3 ===>>> xorg-fonts-truetype-7.3 ===>>> xorg-fonts-type1-7.3 ===>>> 8 leaf ports xauth is needed to enable X-forwarding in ssh.

Hello all. As nobody seems to have experience with this I decided to set up a simple jail to test this. Unfortunately skype keeps dumping core when I'm trying to start it. Perhaps someone has a hint for me how to deal with this. I tried to set up a jail as unrestrictve as possible.

[OT] Why behaves my application different when run in gdb
Hi all. Sorry for asking off-topic questions but I started to dive into C programming. I know a couple of scripting languages quite well but wanted to learn something more low level. What me struck now is the fact that my code will crash (signal 11) while processing a strcpy. When I run the same thing in gdb it won't crash and whats even more important to me: It does what I wanted it to do... Perhaps someone can tell me why a program which crashes repeatedly in console runs fine in the debugger.
