When I do this I keep getting a message saying the host cannot be resolved. I was told the previous person that used the machine deployed a very restrictive firewall on it. I tried service iptables stop, but I am still having this issue. What other firewalls could be preventing me from communicating with other hosts? The firewall is setup in a way that I can only ssh into the machine through a specific machine in a given lab.

Authored by Dan Nanni 5 Comments On Red Hat based systems such as RHEL, CentOS or Fedora, yum is used as a package management tool for installing, updating and removing RPM packages. When you try to install a package with yum command, you may encounter errors for various reasons. In this post, I will describe several common error symptoms for the yum command, and explain how to fix yum errors. 1. Fix 404 Errors Symptom: When you try to install a package with yum, yum throws an error: "The requested URL returned error: 404 Not Found" Loaded plugins: fastestmirror base | 3.7 kB 00:00 base/primary_db | 4.4 MB 00:09 extras | 3.5 kB 00:00 http://mirror.steadfast.net/centos/6.4/extras/x86_64/repodata/e0e507c76dc5e5aa66c1f32632b9dc0a9759d97031ab5a028562a7cb7be6e294-primary.sqlite.bz2: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" Trying other mirror. http://mirrors.seas.harvard.edu/centos/6.4/extras/x86_64/repodata/e0e507c76dc5e5aa66c1f32632b9dc0a9759d97031ab5a028562a7cb7be6e294-primary.sqlite.bz2: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" Trying other mirror. You can get these 404 errors when the metadata downloaded by yum has become obsolete. To repair yum 404 errors, clean yum metadata as follows. $ sudo yum clean metadata Or you can clear the whole yum cache: $ sudo yum clean all 2. Fix Connection Failure Errors Symptom: You get "network is unreachable" or "couldn't connect to host" errors while running yum command.
