Things like cd are shell functions so there must be something else wrong with his permissions scheme. All your programs should exist in /bin, /usr/bin, /usr/local/bin, /opt/bin, or someplace like that. You really shouldn't have any executables anywhere in /home. Providing that is true, everything will work as normal.

I, myself, don't noexec /var as I actually have some programs that need to run that live there (qmail's entire bin directory for example). However, that isn't a big deal for me as I jail my users from access to /var anyway.
I think I see the problem, my /home is not a separate partition. I changed permissions of /home to 766, and then tried to cd~ and was denied permission.

Could this be because it is not a separate partition?

All I know is what I saw. I am just now reaching the ranks of upper newbie so don't blame me if things went awry!

Does it really matter? Spyware isn't a phenomenon in Linux.

Could it somehow possibly exist? Yes. Does it matter? No.

Could it be a phenomenon in the future? Yes. Will it be dealt with then? Yes.

If people are so paranoid, they can just use trusted repositories--most distros have something like this. If people are even more paranoid than that, install software only from source and inspect the source code (warning: you'll have to know programming and actually have time to inspect all the source code). And if you can't be bothered with that and you're paranoid, then don't connect to the internet at all and don't install any programs--hell, don't use computers or install an OS. Maybe the OS itself has spyware.

Geez, people. Just use the friggin' thing!

Even before I knew the word "spyware" or the word "adware" in Windows, I knew right away that something was wrong--my computer ran slower, there were weird programs in my C:\Program Files folder, random pop-up ads would pop up even when I didn't have Internet Explorer open.

If you don't notice anything wrong with your computer, you have two options:

1. Assume everything's okay.
2. Assume that there must be something sneaky lurking--in which case, maybe you shouldn't install any programs at all (or install only from trusted repositories).

Lightbulb Wow this was an amazing thread

Wow this was an amazing thread I think we will all take something form this. Springshades in looking back you are some user. I need to read post more closely. You were correct in saying;

Of course, if you've solely been a Linux user for quite awhile, it's possible you don't really know how spyware works in most cases.
I mostly stopped using windows in 1996, after a very bad Win95 experience.

one question: what functionality is lost by mounting /home noexec (besides the obvious)?? like, for example, will users still be able to use things like javascript in the web browser??
Java will work; the java VM runs outside /home.

javascript != java.

The ONLY thing javascript and Java share is the word "java" in the name. They are not otherwise even remotely related in the slightest.

I agree. At this point I think the best thing to do is just not worry about it as it isn't something that Linux is going to have to deal with for awhile. The only problem I see is that there is a huge group of people who think that Linux doesn't have to deal with spyware because there is something fundamentally different about the operating system that protects it against those specific threats. This MAY be true for viruses and worms (default permissions settings and firewall blacklisting external connections), but spyware operates in a very different way. It mostly relies on the user to do its dirty work.

Best course of action is to not worry about it now, but admit that at some point, it will most likely have to be dealt with IF Linux becomes significantly more popular.

Would blacklisting all known spyware servers like Gator/GAIN, Xupiter, and friends help conserve bandwith? You could find IP addresses using connection tracking.

yeah, it would help a lot... but i suggest you use domain names instead of IPs if possible...
