Pacman, wget: "Network is Unreachable" [SOLVED]

Hello all,

I got back from my summer vacation a week or so ago and pulled my desktop computer out of storage to give it the ol' pacman -Syu. After a lengthy update, I learned of the deprecation of net-tools, so I went into my rc.conf and replaced the network section with that of rc.conf.pacnew and set it up as suggested for eth0 as dhcp. Now, after another week of mainly using Windows, I've hopped back on Arch Linux (x86_64) and attempted to -Syu again. However, I began to get "Network is unreachable" errors, and was unable to get anything downloaded. Any pacman, wget, or curl calls time out with the same error. The strange thing is that I'm able to access web pages through chromium just fine. However, no wget's are working, manual or pacman-run. Curl is similarly malfunctioning. I have done plenty of research through the interwebs, but a majority of the time, the offered solutions do nothing.

One response to similar problems is to make sure a default gateway is set up. Here's the output of netstat -rn. I've double checked this with my school's provided information, and it seems to match up. Should be fine here.

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
0.0.0.0         128.113.192.254 0.0.0.0         UG        0 0          0 eth0
128.113.192.0   0.0.0.0         255.255.240.0   U         0 0          0 eth0

I also have a laptop running Arch64 which I was using all throughout the summer. It has no problems on the network, so it's a likely a problem with my computer and not my school's network. Any ideas, or commands whose output I could post up for further checking?

Re: Pacman, wget: "Network is Unreachable" [SOLVED]

Can you

# ping google.com

and then

# ping 74.125.226.80

if both are fine you should not have problems with dns.

If you boot to init 3, are you able to ping anything or get an ip address? Maybe your window manager is working out the network while on the lower level things are not properly setup?

Re: Pacman, wget: "Network is Unreachable" [SOLVED]

All of my pings time out with 100% packet loss. The only ones which work are those which resolve to my local network (www.rpi.edu and webmail.rpi.edu both work). Pinging google.com or any IP address results in a time out. I'll check init 3 when I get back to the room.

EDIT: Solved it. I've been so busy moving back in to college that I never learned that kernel.org had the security breach and was down for maintainance. Turns out it was the only thing on my mirrorlist. I'm all good now; thanks for the help.
