Linux training
by Montana Quiring 06 Jun '11

06 Jun '11

Hello, This year I would like to put some processional development energy into some Linux course(s) among other things. Are there any good (relevant, current, and uptodate) Linux server courses on-line or in Winnipeg that anyone would recommend? Some topics would probably be intermediate to advanced server admin, server security/hardening, Apache, etc. Regards, -Montana Quiring CTO of QMTS http://qmts.ca

Re: [RndTbl] AGP video card.

The cards in question are actually PCIe cards with a PCIe-to-AGP bridge. I don't believe there were any "native" AGP chipsets with HDMI-out. -Adam Trevor Cordes <trevor(a)tecnopolis.ca> wrote: >On 2011-05-24 Kevin McGregor wrote: >> They made AGP video cards with HDMI out? > >Yes, I just checked and I did sell some HD3450 AGP's with DVI+HDMI (no >adapter).

AGP video card.
by Sean Cody 04 Jun '11

04 Jun '11

I am in need of a decent AGP Video card with DVO for my brother to connect his T-Bird Shuttle PC to his LCD TV. I had purged my collection of legacy gear earlier this year and the cards I have left are fried. I don't need new, just AGP and DVI with basic GPU acceleration (he just watches video at 720p,via DVI->HDMI adapter). If it works/supported with Linspire all the better. -- Sean (mobile)

burning large files
by Trevor Cordes 04 Jun '11

04 Jun '11

I need to burn a 5GB+ data file to DVD-DL, using command line tools in linux. Obviously burning small (sub 2 or 4GB) files to DVD is easy using mkiso and cdrecord, or whatever. Now I need to burn a large file and I'm discovering it's not so easy. It turns out there's a file size limit for ISO9660 of 4GB. Doing a bit of research, it looks like you must burn UDF format instead of ISO, but the UDF burning utilities on linux are limited. mkisofs has options -udf and -allow-limited-size which may solve my problem, though the "alpha" labelling of it doesn't inspire confidence. My other issue is I need to know exactly how much usable (non-FS) data space I get out of a DVD-DL. That number is well known down to the byte level for ISO9660 on DVD (single layer). I'm having a really hard time finding hard numbers for DVD-DL and UDF overhead. One would assume you get DVD-SL x 2 raw space. And one could probably guess at some reasonable overhead for UDF. Still, hard numbers will help me avoid coastering a multi-$$ DVD-DL blank. Hopefully someone has some experience with this? Thanks!

Usually it's the other way 'round, as the mgmt port is used for remote "lights-out" installs. You can connect to a virtual console port through the sun mgmt port, so you should never need both.

What its usually meant by that is that you must physically put the RSC module into the server, and you must cover give it an IP address, etc. before you can do anything with it.

Not if there's a frame buffer installed. And that sound like you're in the host serial port, not the management port. Which do you want to be connected to?

Turn off hardware flow control (RTS/CTS or DTS/DSR) and use software flow control (XON/XOFF) instead. Also, if you don't want to use minicom, (the modem AT initialization is a pain to turn off completely) just use screen instead: "screen /dev ttys0 9600" -Adam Kevin McGregor <kevin.a.mcgregor(a)gmail.com> wrote: >This is driving me nuts, since it was working and now it isn't and I have no >idea what has changed.
