Since this is on-topic for a Netatalk thread, here are the nitty gritty details on what is stored with each AppleDouble backend: The "old" AppleDouble v2 system: All metadata for files is stored in a separate hidden directory called .AppleDouble with equivalently named files. These files follow...

Took a look at the materials on the AppleTalk for Programmers CD. Sadly nothing too detailed in the lessons, but there is a really nice HyperCard stack with the various AppleTalk packet format graphics in it.

OK, the above will only work if you are using ea = sys and NOT the old AppleDouble v2 system with ea = ad. IT should be pulling the resource fork from the ._ files as I have it working here. You need both files in the directory together, Netatalk always stores the resource fork in the ._ file.

In addition to the ad set commands, add the following to your script to "fix up" the header of your ._ files so Netatalk stops complaining about bad AppleDouble data: printf '\x4E\x65\x74\x61\x74\x61\x6C\x6B\x20\x20\x20\x20\x20\x20\x20\x20' | dd of="._Applications HD.img" bs=1 seek=8 count=16...

Its not a new idea, look up the CBS sequential color television system. Early on, many flatbed scanners were not "single pass". They were actually modified grayscale units doing what you want to do, except that they automatically switched out the red, green, and blue color filters with each...

Reading thru the source, it appears that if a ._ file has extended attributes embedded in it, that Netatalk will indeed copy the FinderInfo from that file and into a metadata EA if one isn't found. It will also re-write the ._ file minus the embedded extended attributes (discards them) with the...

Don't worry about the "bad CNID" error messages, those are normal for files added from outside the share and the dbd tool is fixing them. The "Bad AppleDouble" message is also from dbd. Looks like it only throws that with the ._ files. They likely aren't 100% like what Netatalk expects since it...

You don't run ad cp at all. Copy/extract the files into the share folder like they are standard UNIX files, then run ad set to set the filetype/creator, which forces creation of the Netatalk metadata EA. After that, Netatalk will update the CNID database on access, running dbd is optional. The...

OK, the lack of a Netatalk metadata EA is the problem, do the following with your files after you extract them: ad set -t dimg -c ddsk "Applications HD.img" ad set -t dimg -c ddsk "NetBoot HD.img" ad set -t chrp -c tbxi "Mac OS ROM" Also, the pax utility that comes with Debian has really...

In theory, you should be able to put both the file and the matching ._ file into the share and it'll "just work", minus the filetype/creator (netatalk doesn't copy the FinderInfo from the ._ file to its metadata extended attribute). You don't need to run dbd for that anymore like with netatalk...

Nothing has come up at all in my searches. Now that slide deck has something that might have been mentioned in the original document. Namely the overview of the algorithm for a node to bootstrap determine its network address.

I await a detailed change log of the various Performa System 7.1P releases now that all of them have been unearthed. :cool: A friend had a Performa 600CD growing up, so that purplish desktop background is burned into my brain. It was annoying when I used other machines and couldn't find it...

These were likely direct clones of what was commonly sold as the Logitech ScanMan hand scanner. Macs got a SCSI interface, while PCs had a dedicated ISA interface. Even the Apple II got an interface that sold as the Vitesse Quickie.

The xattr command is macOS specific. On Linux you can use getfattr and setfattr.

@MacinJosh A2SERVER is being updated to incorporate Netatalk 4.x. Its been a long process (particularly because of the EA support and conflicts with ciopfs), but its getting there. With regards to Synology and extended attributes, it appears that the Disk Manager software is storing them in a...

Maybe the BlueSCSI 2 is throwing other devices onto the bus even if they aren't configured? It would be useful if there was a utility that scanned and dumped the devices detected on SCSI bus. Is there a bluescsi.ini file on the card? I would remove it if so. Stuff like the DaynaPort Wifi...

The level 2 protocol was likely FDDI (100Mbit) on these early fiber networks. Later on it was easier to just run Ethernet frames over fiber when 100Base-FX became available. Remember in the late 80s, Ethernet was not a sure bet at becoming the standard for the physical layer. Token Ring and FDDI...

As per the GS/OS source, the following ROM detection is done to determine if an "old" (not High Speed) Apple SCSI card is installed. It then checks code in the I/O select space at $Cn00 thru $Cn57 where n = slot number. It points to bank $00 then checks $C8XX for $02 (this is a check for the...

Make sure both the modified "SCSI.Manager" and "SCSIHD.Driver" files are in the "DRIVERS" folder of the System Folder on your startup disk.

Do not install the driver. You should be able to partition and access a drive from GS/OS without it. I suspect that the ROM on the card differs from what the patched driver has in it. Its one of the pitfalls of modifying a design.
