Ah, memories! These days, setting up hardware on Linux is often easier than it is in Windows. Lots of drivers are built-in and auto-detected, and many are provided through a distribution channel that makes it almost as easy.
Wireless networking, however, is a bit of a throwback to the old days. Half the hardware doesn’t have Linux drivers, and half of the devices that do require you to hunt for the driver — based on the chipset, of course, not on the name or model number on the box — and compile it yourself. (At least these days, you can sometimes run a tool to adapt the Windows drivers if there’s no native Linux option.)
The steps I actually needed to take to set up wifi on my Fedora 13 desktop probably only amounted to about 10 minutes. Unfortunately it took a lot of false starts to get there. I had installed a Zonet ZEW1642 PCI card, which my initial research suggested would be supported by the built-in rt2860 drivers. As it turned out, it wasn’t that simple. Continue reading
Last week I connected to my Linux desktop from my Mac laptop, and Finder wouldn’t let me copy files over to the Linux box. Even stranger, it would delete the original file on the share after stating that it didn’t have permission to access it!
The error message it kept popping up was:
The operation can’t be completed because you don’t have permission to access some of the items.
So it didn’t have permission to access or save the items, but it had permission to delete them? Clearly the error message wasn’t telling the whole story!
Even stranger: if I opened a file with an application like TextWrangler or NeoOffice, they had no problem saving it! It was only Finder that had the problem!
Now, I’ve successfully transferred files back and forth between these computers many times before, but I had changed two things recently:
- Upgraded the Linux box to Fedora 13.
- Installed the Mac OS X 10.6.4 update to Snow Leopard.
I didn’t have much luck searching online, maybe because I was looking for the wrong terms. The closest I came up with were discussions like this one, but they all involved a server using netatalk or other AFP file sharing implementations. I’ve been using samba (Windows-Style SMB shares) on the Linux box ever since I had some problems with Netatalk and decided that since the Mac would connect via Samba, I wouldn’t worry about it.
I idly posted the problem on Twitter. My brother replied that he’d run into the same problem (on Ubuntu, IIRC), and suggested turning off Unix extensions in Samba. That meant opening up
/etc/samba/smb.conf on the Linux box and adding the following line to the “Filesystem Options” section:
unix extensions = no
I restarted Samba on the Linux box, and that was it. The Mac was able to copy files over without any errors!
I hope this post helps someone else solve the same problem.
I think I finally fixed it.
This stupid “OMG Nepomuk is not running!” error has been dogging me every time I launch KMail, ever since Fedora upgraded KDE. I followed all the directions on fixing Akonadi, and nothing worked. Finally, it turned out that there was a config file telling it to load the old-style “redland” database — which doesn’t exist in current versions of Nepomuk — instead of the new “virtuoso” database.
The file was in
~.kde/share/config/nepomukserverrc and the item in question is “Used Soprano Backend.” I changed it from “redland” to “virtuosobackend” as described here and now it actually starts Nepomuk, and KMail doesn’t complain when I start it!
Someone at KDE decided to massively overcomplicate things!
