Some applications not connecting to the internet [SOLVED]

hooya · 2015-01-11 20:10:42

Trying to install anything from AUR is no longer working, I always get 404 errors during the mkpkg when the source download tries to happen. I can't even grab the tarball from the terminal with curl using an https address. Happens on all packages.

Additionally, Dropbox is no longer seeing a connection to the internet.

I am not behind a proxy. I have never set up any proxy settings. I have a typical Comcast residential connection. Browsers access http and https just fine.

I honestly don't know where to start troubleshooting on this.

http://www.yougetsignal.com/tools/open-ports/ shows all my ports are closed, but this should be normal as I'm not trying to serve anything from this computer.

Anyone that finds this. Still an unsolved problem.

See my edit. My post had been transmogrophied when I posted.
What about

wget google.com

?

hooya · 2015-01-11 20:31:44

I saw the improper BBC tags and stripped them before running the command and stripped them out.

Testing with google.com did work.

Pacman will work with -Sy however if I tried to enter a custom repository those return with 403 or 404

Is it my router? I did get a new one recently, but because all web services have worked and pacman updates correctly I didn't think there was any problem until I noticed that dropbox wasn't connecting, then I had other problems when I started digging. It's a Netgear C3700, and I haven't done much of any tweaking or customization on it. The machine in question is connected through ethernet, not wifi.

ewaller · 2015-01-11 20:50:12

That is a problem. You are not getting out of your private network (Note that the first set of digits is 192. ? )
What are the contents of /etc/resolv.conf ?

Edit: We were posting at the same time. Yes, I suspect the DNS server in your router.

Weird problem on the router then. I'll check the DNS settings for it. Thought it might be port forwarding but that must not be it.

hooya · 2015-01-11 21:02:17

Router was set to receive DNS from the ISP. The defaulted manual numbers were the same as in resolv.conf, and if I switch to the manual numbers with the router everything is giving me the same results.

I'm stuck...

Edit: The router has its own traceroute utility in a diagnostics section:

Performing traceroute to (216.58.216.68), 255 hops max, 72 byte packets

01 sendtotraceroute: wrote www.google.com 72 chars, ret=-1

idk...

You need a local DNS, say dnsmasq.

hooya · 2015-01-11 22:39:18

I set up dnsmasq according to the wiki. No change at all in my connectivity for those apps - edit: actually it simply broke my network completely. So I either didn't set it up right or it does break things on my system.

I'm posting to this board from the effected computer. Traceroute on an android phone and on another arch linux machine on the same network (wifi) have no similar issues - all programs connect properly including dropbox and commands in the terminal. This is something broken on this computer, not something that needs fixing. No idea why the traceroute utility on the router itself doesn't work but I don't really care about that.

Any other thoughts? I'm fairly certain it's not a DNS problem now, and it's not a router problem, since other computers on the network have no similar issues.

If I use a net utility to traceroute I have no issuesl
http://www.monitis.com/traceroute/
Give me valid route results to various places online.

Just had a realization. My new router does not support IPv6 at all where my old router had some support. Stupid downgrade, but my old net connection was a separate router and modem, this was required to continue getting internet through our local cable company.

So it might be an IPv6 compatibility issue. Any way to just set everything to IPv4 globally on the computer? Would that fix it?

If the traceroute indicates that falconindy's site maps to a private address inside your network, yes, you do have a DNS issue.

What about this:

wget http://96.126.110.212/archive/cower/cower-12.tar.gz

That worked. It's really unpredictable.

Also, see my above edit.

I was starting to wonder that very thing.

Yes, it can be disabled. https://wiki.archlinux.org/index.php/IPv6#Disable_IPv6

hooya · 2015-01-12 03:15:50

Looks like it was already turned off for my wired network in NetworkManager. I've added the indicated setting from the wiki for my dhcpcd conf and just rebooted with the kernel parameter through grub.

Dropbox still doesn't work, "traceroute code.falconindy.com" also doesn't work as before.

However, "traceroute 8.8.8.8" works just fine, as does "traceroute www.google.com". So it's not completely on my end. Some destinations don't like me.

Still can't load the db from that one repository or get the file from aur that I was trying for. I can download the tarball through the website but curl gives me an error: Failed to connect to aur.archlinux.org port 443: Connection refused
this package: https://aur.archlinux.org/packages/dropbox/

Failed to connect to aur.archlinux.org port 80: Connection refused

hooya · 2015-01-30 03:00:46

To update, I just tried loaded up a Virtualbox running Windows XP and dropbox from within that virtual machine connected just fine. There must be something specific to my network environment in Arch only that is causing the problem, as it's very service dependent. Still looking for a solution to this.

Is there a way that I can reset my entire network config as if my machine were a new install? I'm thinking about going nuclear. What is the current default network config program for new Arch installs? Thoughts on where to find what files I should remove to get old network configs out of my system?

hooya · 2015-02-17 19:45:44

Turns out this may be a router issue. Plugging my desktop into another router that is then plugged into my cable modem router solves the connectivity issues. The Traceroute was stopping at not the router itself but the stupid Netgear "Readyshare" server that is built into the router, which was obviously not the right final destination. If this is a DNS issue or something else I don't know but the hardware change has at least solved the problem for now.

Still not sure why browsers and virtual machines would connect fine, and why it works in this new hardware config, but it works.

Arch Linux
