[gentoo-user] [OT] Transferring old video tapes to disk
Hi multi-media gentooers, I know you're out there :) A friend just gave me a 15-year-old VCR, and it still works! That's good news because I have some 25-year-old video tapes that I haven't been able to play since my old VCR broke 15 years ago. Now's my chance to save the tapes to a newer format. (Until the new format becomes obsolete in another year or two.) Transferring the audio is easy even for old non-multi-media me, but how to get the video off the tape and into the computer? Do I need a new video card with special stuff? Or what? Thanks for any clues.

Re: [gentoo-user] Strange outbound requests
I'm still getting the blocked outbound requests to port 3680 on my firewall and I'm running the above script (changed 993 to 3680) on the local system indicated by SRC in the firewall log, but mystery.log remains empty. I tested the script with other ports and it seems to be working fine. Also the MAC indicated in the firewall log is 14 blocks long and the local system in question has a MAC address 6 blocks long according to ifconfig, but the 6 blocks from ifconfig do match 6 of the blocks reported by the firewall. Does this make sense to anyone? >>> >>> Does not make sense to me, sorry. :-( >> >> Since my local firewall is rejecting the outbound requests, the time >> elapsed between the request and the block should be very short.

If so, how would you recommend fixing that? Try configuring your local firewall to log the request. There may be something useful, such as logging an associated PID or user, that you can add there. I don't know. Alternately, you could DROP the outbound packet rather than REJECT it; that should cause the connecting process to wait several seconds until it times out. > > I'm also wondering if there is a command I could run on the > router/firewall machine that would log something from the outbound > request.

Is the 'local firewall' on the connecting host, or is it on your router? As far as logging goes, you can set up a rule (prior to your DROP or REJECT) with a target of LOG. The packet will show up in syslog. -- :wq

Is it possible the 'sleep 1' portion of the script is causing the failure to log the connection request? The outbound connection is only attempted a few times per day. If so, how would you recommend fixing that? If the firewall is being nice and rejecting the connection, then yeah, it could be opening/closing in under a second. `sleep` doesn't require an integer[1], so you can probably have it sleep for 0.1s or something like that. I'm also wondering if there is a command I could run on the router/firewall machine that would log something from the outbound request. Even if the information logged isn't useful, it would be nice to see a confirmation of the outbound requests logged from somewhere besides the firewall. What kind of firewall is it? Can you update the rules? If so, make it silently drop outbound connections instead of rejecting them; that way, the connection will hang open for a little bit. [1] This is probably a bash-ism, but it works here.

If so, how would you recommend fixing that? I'm the wrong guy to make recommendations on any sort of scripting, but if sleep 1 is not enough, could sleep 2 or 3 be adequate to complete writing what it is that is being watched? > I'm also wondering if there is a command I could run on the > router/firewall machine that would log something from the outbound > request.

However, it may consume tonnes of disk space if you leave running all the time. Have you checked if such connection attempts take place when you start up the machine? If yes it may easier to capture it. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

What > the heck is a modeline? A modeline is a one-liner way of representing a display driver mode. I always preferred the block form; it's far more readable. It's been almost a decade since I've written one, though. Haven't really needed to since XFree86 4 came out. I don't remember all of the bits of information in it, but here are some of the highlights: * Vertical refresh rate (in kHz): how rapidly the CRT's electron beam crosses the screen horizontally. * Horizontal refresh rate (in Hz): how rapidly the CRT's electron beam crosses the screen vertically. * Some horizontal and vertical overdraw values I don't remember the specifics of, but it amounts to realizing that the electron beam is active past the bezel of your monitor. "xvidtune", by the way, was an awesome way to do live testing and configuration of these values, and it would emit a modeline for you when you asked it. -- :wq

Sounds about like what was going on at his place and it's a reasonable evaluation potentially. I guess I could have made it a bit more clear early on - I'm not looking to solve anything here and I'm not buying KVMs. I was just curious as to the root cause of the problem. I've seen it discussed periodically for over a decade but never any strong analysis of why it happens. It's not a huge problem to the community. Cheers, Mark

Thanks for the ideas, Mark Many of the cheap KVM models do, indeed, mess up the EDID data coming from the monitor.

Re: [gentoo-user] Strange outbound requests
If the machine is running linux, then 'watch "lsof -n|grep TCP|grep 3680"' as root is a sloppy but effective way to find it.

Video resolutions / refresh rates / timing / &c is a bit of a black art. What the heck is a modeline? The manufacturer of a KVM isn't going to be able to test it with all the 10,000 monitors available on the market today - not even 1% of them. They're happy if it works 99% of the time, and if you complain to them they'll say "oh, it must be a bug with that monitor" and maybe, eventually, give you a refund for the sake of a peaceful life. There are probably a handful of different KVM chips that are made by big manufacturers in Taiwan, and then sold by the 10,000 to other manufacturers, this time manufacturers of actual KVM units. These second tier manufacturers probably all wrap the KVM integrated circuits up in slightly different ways, using slightly different resistors and capacitors to interface with input and output. So in terms of your specific questions, I'm not able to answer very helpfully. I think you could waste a lot of time trying to get these answers, whereas you could swap in a specific model and try it in a matter of minutes - and that way you'd know for sure. Stroller.

According to the manual, if Windows set up 1680x1050 then it must have been using the only rates, etc. (I think!) And yes, the interface on that monitor is the old-style VGA. It's fairly clear that X kept saying there wasn't a resolution available from the monitor to support what I had requested in the xorg.conf file. I was asking for 1680x1050, being told the monitor didn't support it, and then given 1280x1024 instead. When he removed the KVM all those messages went away, X & KDE said the monitor was running 1680x1050, and the OSD on the monitor itself said it was doing the requested setup.

However, if I understand the nouveau driver correctly then that won't work for using the nouveau driver as it requires KMS. Digging a little deeper into the nouveau driver and KMS[1], I discovered that I probably need to have CONFIG_VT_HW_CONSOLE_BINDING set in the kernel config as well - which it wasn't. So that probably explains what was happening as CONFIG_HW_CONSOLE was set, so there may have been two drivers competing for fb0. Now off to build a new kernel...

[gentoo-user] KVM problems - anyone know _why_ it happens?
I've seen reports for years about folks having problems with some KVMs under Linux. I've never personally had one myself. However I've been helping a Windows friend break his Redmond addiction over the last few months using Gentoo. He has a nice 3 monitor KDE-based system that's been working fine but there was one monitor that refused to set up with the right resolution. We left it alone for a long time as it was usable but finally yesterday got together to figure out what was happening. From the title it should be clear that the problem was a KVM hooked to that one monitor. Removing the KVM completely solved the problem. Now, what I'm wondering is why this same video card/KVM/monitor combination which apparently worked in Windows should have any problems in Linux? Anyone know why? In the spirit of full discloser I don't really know that this _specific_ video card was tested in Windows, but he owns multiple NVidia 8400GS cards and it's my understanding that other 8400GS cards did work with this KVM & monitor, so unless it's this specific card having a defect, or even being just a bit weak in some way, it would seem to be the insertion of the KVM itself that upset things. Looking at the monitor's specs/requirements for running the higher resolutions it uses, as should not be a surprise, higher frequencies to do higher resolutions. If the KVM was filtering those a bit then it's possible things wouldn't work, but that doesn't explain why it did work in Windows. Basically, I looked around in Google for anyone that had real info about why this problem occurs, couldn't find any that made sense, and am wondering how to choose a KVM that's going to work out of the box short of asking for model numbers, etc. Cheers, Mark

I assume we'll update the management apps to handle > configuration of IPv6 as well. Here's an elucidation of what I was thinking. I'll assume the company building the product builds many embedded systems. I was thinking you could use an assumed ULA prefix as associated with all of these products, e.g. fd62:f67b:fcb9::/48.[1] You've then got 32 bits of address space for product organization and categorization before you come down to a /64, whereupon each device in the line gets its own unique address derived from its MAC. You could then either have the device broadcast an RA for that /64 or manually configure another host to use that /64 to access that device's initial configuration interface. Anyway, that's what I was thinking there. Just food for thought. :) [1] I used an Android app which implements RFC4193 to generate this prefix; you'd obviously want to come up with your own prefix. -- :wq
