Proxies for the Iranian protestors

I noticed over on planet.ubuntu.com that one user is calling for volunteers to setup anonymous squid proxies to allow the protestors uncensored access to the net. He has nice How-To setup including ACL lists to block access to Iranian government agencies and how to communicate information regarding your proxy. If you have a virtualization setup, this would most likely be an easy and secure way to create the proxy and then take it down later.

If anyone is interested you can find more info on his blog post here...

Geocaching

From reading other posts here, I know there are geocachers lurking around. I'm not sure how many of you are familiar with the geomatejr, but this is one slick device. It's geocaching right out the box, and for $69.95 you can't go wrong. I picked one up yesterday and immediately tried it out and it worked awesome, leading me directly to the closet geocache.

It's going to be getting an update kit which will be available soon (July) that will let you update the database and allow software updates. If you're into spontaneous geocaching, just pull this out and fire it up.

Say it ain't so...

I hope this is just bad speculation on the part of investors, but I hope Red Hat does not sell out to Oracle. If there is one company I despise as much as Microsoft, it's Oracle. Please... just say no to an acquisition!!

cp -a command bug or selinux bug??

I'm buidling an NFS installation server and could not get the files from the mounted iso image to copy into the /install directory I created until I spoke to the fine folks in the #rhel channel on freenode. The conclusion was a bug from 2 or 3 years ago that was fixed in Fedora but not RHEL. Why is something so basic and necessary still broken on RHEL? Is it possible this is not a bug and just an outdated man page or incorrect documentation from Redhat?

Let me tell you exactly what I did to cause this problem to happen.

1) [root@habanero /]# mkdir /install
drwxr-xr-x 2 root root 4096 Feb 18 11:06 install

2) mount -ro loop /home/xxxx/isos/rhel-server-5.3-i386-dvd.iso /mnt

3) cp -ar /mnt/. /install
UPDATE: cp -a /mnt/. /install (same errors as below)

4) weeeee, look at the errors - truncated of course :)
cp: cannot create regular file `/install/./EULA': Permission denied
cp: cannot create regular file `/install/./GPL': Permission denied
cp: cannot create regular file `/install/./README-as.html': Permission denied
cp: cannot create regular file `/install/./README-bn.html': Permission denied
cp: cannot create regular file `/install/./README-de.html': Permission denied
cp: cannot create regular file `/install/./README-en': Permission denied
cp: cannot create regular file `/install/./README-en.html': Permission denied
cp: cannot create regular file `/install/./README-es.html': Permission denied

5) now look at the permissions on my /install directory
dr-xr-xr-x 2 root root 4096 Jan 6 17:39 install

6) Now here's the kicker... if I do any of the following, the files copy into the /install directory without issue.

cp -r /mnt/. /install
cp -dpR /mnt/. /install (equivalent of -a)
cp -ar /mnt/. /install (with selinux set to permissive with setenforce 0)
cp -a /mnt/. /install (with selinux set to permissive with setenforce 0)

So I ask you... is this an selinux bug or cp command bug?? Comments more than welcome!

BTW - Redhat documentation states using the command cp -a (just for the record)
