comment How does one change user's home directory in Ubuntu 9.04?
@Aleks the functionality of usermod hasn't changed in years, or probably decades, so this answer should still be valid. As for why you're only seeing your desktop background, perhaps something else in your desktop environment depends on the username, in which case usermod doesn't know about it. But I can only guess at why this is happening (without having access to the system).

comment Options to configure Apache to take into account other folders despite /var/www
What URLs do you want the files in those other directories to be accessible at? There are a few different methods to use, depending on the answer to that question. Or is your problem that Apache is not even able to access the files and you want to know how to set permissions to allow it to do so?

Which desktop environment are you using? (Gnome, KDE, etc.)

comment Time to zip very large (100G) files
Note that if a suitable compiler is available on the machine, and the filesystem permissions are not set to prohibit executing binaries from the directories you have access to, you can compile pigz and run it from wherever you happened to build it, without installing it. If there is no compiler, you could cross-compile it on another computer, although that's starting to get into more effort than might be worth it. (Depending on just how badly you need this compression to run faster, I guess.)

comment How do I set up SSH so I don't have to type a password, and without using a public key?
Sorry I forgot to come back and provide feedback on this. After modifying /etc/hosts as suggested I get debug1: Unspecified GSS failure. Minor code may provide more information Generic error (see e-text). Nothing else in the output is relevant to the error.

Yeah, it would... I'll ask them about it, but for now hopefully your fix should settle things. I'll try it tomorrow.

This seems like it should be pretty close to ideal for me, but it doesn't seem to work - I was able to login with Kerberos successfully (no error messages), but I still get prompted for a password. Error messages from ssh -vv are similar to the trace I posted except I get debug1: Unspecified GSS failure. Minor code may provide more information\n Server not found in Kerberos database instead of the thing about the credential cache file not being found.

@Broam I can't imagine that I'd be the first one to ask, so presumably they have some reason for keeping it that way... I suppose it wouldn't hurt to try, though.

The master connection would reset when I shut the client down, though. So this isn't an ideal solution, but it would be a slight improvement over my current situation.

@grawity No /etc/krb5.keytab, but it does have /etc/krb5/krb5.keytab. I don't have access to the contents. The server name is sftp.pass.psu.edu (I don't think there's any harm in giving that name out) if it helps you explain the procedure.

comment Why don't you see binary code when you open a binary file with text editor?
@ZJR: No reason they shouldn't. Many hex editors do let you view file contents in binary. Programmers just don't generally find it as useful as the hexadecimal view, so you don't hear about it as much.

comment How do I delete a directory that appears to contain nameless files?
I haven't run fsck yet, because I need to unmount the filesystem first.

No luck, running with sudo fails the same way.

I've edited that into the question too.

Silly me, I completely forgot to include that output ;-) but yes, that was what brought my attention to the problem in the first place.

KMail is on Kubuntu, I forget which version but it might be 9.10, and Thunderbird is on Windows 7.

comment Protecting a SVN server
Yeah, but git runs over ssh by default (probably Mercurial too, I'm not familiar with it) so you automatically get all the benefits of ssh. Plus, if your concern is repository damage, using a distributed VCS automatically gives you a whole slew of remote backups, since each developer should have a reasonably up-to-date clone of the repository. Besides, the ease of branching and merging in git or Mercurial compared to svn may make it worth the learning curve.

comment How much does a gigabyte worth of data physically weigh on a hard disk?
Indeed, you're talking about less than a trillionth of a gram, though it depends highly on the storage medium. I did a blog post about it once (and thought I'd leave a note here for interested readers).

comment How to send a large file securely?
I'm not at all convinced by your objections to SSH. As Keith said in comments on the question, you can configure it pretty much however you want, e.g. disabling all logging and only accepting connections for a single unprivileged user.

What do you need (or want) the older ebuilds for?
