I recently returned to my college campus for classes and brought my desktop computer running 64 bit Arch Linux out of storage. After updating my packages with
sudo pacman -Syu, I rebooted and began to have some strange problems. While I can still access web pages through chromium and uzbl, some other programs such as pacman, wget, and curl are now failing to work. I also fail to ping any websites outside of my school's local network (although all my friends report the same issue on their Windows computers, so this could be my school's doing). I've mainly done my testing through wget, so I recognize a couple errors now. The usual one I've been getting is as follows:
:: Synchronizing package databases... --2011-09-08 17:28:59-- ftp://mirrors.kernel.org/archlinux/core/os/x86_64/core.db => `/var/lib/pacman/sync/core.db.part' Resolving mirrors.kernel.org... failed: Name or service not known. wget: unable to resolve host address `mirrors.kernel.org'
After doing hours upon hours of google searching, many similar problems can apparantly be fixed by forcing the use of IPv4. However, modifying pacman.conf to append -4 to the wget command only changes the error to:
--2011-09-08 17:36:56-- ftp://mirrors.kernel.org/archlinux/core/os/x86_64/core.db => `/var/lib/pacman/sync/core.db.part' Resolving mirrors.kernel.org... failed: Temporary failure in name resolution. wget: unable to resolve host address `mirrors.kernel.org'
I've tried countless changes and nothing has worked so far. I'll post up some config files below. One last thing to consider is that at my school (Rensselaer Polytechnic Institute), they have redesigned their internal network to be fully IPv6 compatible. I also don't know what other firewalls or restrictions they may put on us. However, I do have a laptop running on the same network with nearly identical configuration. It has no troubles at all, so something must be wrong with this computer.
