What about "yum update yum", did you try that one before?

Filipe

Yes, not works. I'm using this yum version:

[root@juzgado ~]# yum --version 2.4.3

[root@juzgado ~]# cat /etc/redhat-release CentOS release 4.6 (Final)

Looks like I can't install any package with yum.

Is there a proxy between your machine and the Internet?

See this question in Yum's FAQ: http://wiki.linux.duke.edu/YumFaq#head-49047d5d448aee45946da9394fa57b7041a9d...

Are you able to download these packages using "wget"?

yes, I not have any proxy and wget works:

I suggest you try using a FTP mirror, you can find one here: http://www.centos.org/modules/tinycontent/index.php?id=30

Then edit your /etc/yum.repos.d/CentOS-Base.repo, comment out the "mirrorlist" lines, uncomment the "baseurl" lines and change the URL from http://mirror.centos.org/ to ftp://... using the mirror you choose. Then run "yum clean all" and "yum update" again. If the issue is indeed an HTTP proxy, using FTP might work for you.

You can also use the command line they suggest in the Yum FAQ to find out if you have proxies. Using your mirror that would be: echo -e "TRACE / HTTP/1.1\nHost: mirror.centos-br.org\n\n" | nc mirror.centos-br.org 80

Actually, my suggestion to use "wget" was a little misguided, as the issue here seems to be that "yum" uses HTTP/1.1 and some advanced features of the protocol, so the fact that "wget" works doesn't necessarily means all is well...
