Thank you for reporting. This is probably your /etc/resolv.conf file not being generated correctly. Any chance you can take a look at it's contents and compare the DNS servers with ipconfig /all at the cmd prompt?

Also, a couple of questions:

1) What is your network connection (wifi / wired)? 2) Are you on a VPN?

If you're on wifi, can you try and switch to a different network and back? If not, try uninstalling through "lxrun /uninstall" and reinstall in Bash.

Let me know if any of the above work. I will also be writing a bug on our side for this.

[robertsmieja]

I'm on a Wired Connection, without VPN. I do have an IPv6 enabled router/modem, and am using NAT.

vi /etc/resolv.conf results in the following:

nameserver 2601:19c:4500:5e6b::1
nameserver 192.168.1.1

ipconfig /all results in the following (I snipped a bit, let me know if there's something I left out):

[russalex]

Thanks. Sending this off to the dev team to take a look.

[russalex]

@robertsmieja. one more question. Any chance you can send me the rest of your ipconfig /all? If you don't want to post feel free to DM it to @richturn_ms. Just tell him it's for me.

[robertsmieja]

Here's the rest. I think the only identifiable info in it is my MAC address which I already shared. Whoops.

[jokeyrhyme]

Out-of-the-box I had apt-get update etc working just fine on my machine. No VPN, no wireless, ethernet hardline, but I do have the Hyper-V and VirtualBox virtual bridging interfaces.

[robertsmieja]

Well if I had to take a guess, there's an error creating a socket so I have 0 network connectivity. It could be a "driver" issue where the Ubuntu distro doesn't have the driver for my network card, or something to that effect.

What's suspicious is that it's complaining about "invalid argument" for the setsockopt function call in socket.c, where the call "setsockopt(20, SO_TIMEOUT)" appears to be missing one argument, according to documentation: http://man7.org/linux/man-pages/man7/socket.7.html

Here's the ifconfig and ll /proc/net/ output, which may be useful:

[jernejs]

I have the same problem if I leave the ipv6 nameserver first in /etc/resolv.conf. Removing (or moving it to the last line) makes resolving work for me.

[jokeyrhyme]

@jernejs good call. My working scenario is IPv4-only, without any IPv6 internet connectivity.

[jacqinthebox]

Same problem here, no internet connectivity.

root@localhost:/# ifconfig
Warning: cannot open /proc/net/dev (No such file or directory). Limited output.

Here I'm pinging my gateway:

root@localhost:/# ping 192.168.2.254
ping: icmp open socket: Socket type not supported

I'm on a wired internet connection and disabled the Hyper-V bridge just in case. No VPN.

Here I'm trying to reset the network:

root@localhost:/# service networking restart
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: No such file or directory
 * Running /etc/init.d/networking restart is deprecated because it may not re-enable some interfaces
 * Reconfiguring network interfaces...
ifdown: failed to open lockfile /run/network/.ifstate.lock: No such file or directory
ifup: failed to open lockfile /run/network/ifstate.lo: No such file or directory

And for the record, I run Ubuntu as well on this machine (dual boot) and it never has problems recognizing my network interface card.

Any suggestions? I'm so happy with this feature. :)

[pallatee]

I have same symptoms as @jacqinthebox but I am able to install packages with apt and access internet with links

[gdude2002]

I got networking working on mine by disabling my AV's firewall. That won't fix all networking applications, but it'll get apt-get working.

[jamesscholeyweb]

I can also confirm that disabling firewall in Bitdefender solved this for me. I tried also with allowing bash.exe through but didn't work so i'm assuming some other services need to be allowed through firewall. So for now have it disabled and using windows firewall and everything ok.

[gdude2002]

Images from BfW seem to be completely separate from normal Windows processes. They do exist, and they don't show up in the task manager, but you can see them in the resource monitor.

For example, in the below screenshot, you can see an image named http, which shows up when I run apt-get update.

---

Even more curious:

root@localhost:/mnt/c/Users/-gdude2002# http
The program 'http' is currently not installed. You can install it by typing:
apt-get install httpie

[thanosk]

I am running Win10 build 14316 inside VMWare on Ubuntu 15.10 host OS. VMWare networking is configured as Bridged for Win10 guest OS. LAN situation on this PC is ethernet-based.

MS Bash did not correctly generate /etc/resolv.conf, it was totally empty. I had to add a simple nameserver 192.168.1.254 (my home router) in order to get it working. I'm also attaching the output from ipconfig /all (with snipped MAC address) if that helps. ipconfig-output.txt

[gdude2002]

Oh, right, I should point out that I'm running bare metal here.

[jacqinthebox]

Thanks @thanosk, I can confirm apt-get update is working now as well now after adding the nameserver to /etc/resolv.conf.

The regular Linux network troubleshooting commands I tried result in rather cryptic output in this enviroment, so I was on the wrong track thinking it was a hardware problem.

[jolibert]

Same problem here, running on native hardware (thanks thanosk for the vmware users but that did not work here). Using a "Killer e2200 ethernet" interface, popular amongs gamers. Already had complications with it and windows.

Nice to see that project btw, will be glad to participate more.

[gdude2002]

@jolibert Does apt-get update work for you, or does it hang?

[jolibert]

My bad, it works with update. Thank you, cat > /etc/resolv.confseems the solution.

[gdude2002]

@jolibert It seems that only certain types of sockets are working at the moment, that's why I asked. No ping yet, unfortunately. apt-get seems to be working properly though.

[jolibert]

@gdude2002 Linux reflex, if no icmp (or ping) then all is wrong. Thank you.

[ghost]

Same here, no connection to archive.ubuntu.com. Had to remove fritz.box and some 10.xxx.xxx.xxx entries from resolv.conf to make it work.

[gdude2002]

@Poddr Did you try the suggestions in the rest of this issue?

[ghost]

Yes, and worked for me.

[Aneurin]

So I spent ages investigating this by looking in what turned out to be the wrong direction. DNS lookups using the default BIND tools don't work regardless of the DNS server used. For example:

root@localhost:~# dig archive.ubuntu.com @8.8.8.8 socket.c:2447: setsockopt(20, SO_TIMESTAMP) failed: Invalid argument socket.c:1915: internal_send: 8.8.8.8#53: Invalid argument socket.c:1915: internal_send: 8.8.8.8#53: Invalid argument socket.c:1915: internal_send: 8.8.8.8#53: Invalid argument

Forcing TCP gives a slightly different error:

root@localhost:~# dig +tcp archive.ubuntu.com @8.8.8.8 socket.c:1915: internal_send: 8.8.8.8#53: Invalid argument ;; communications error to 8.8.8.8#53: end of file

So at first this seemed like DNS connections simply wouldn't work at all, even when specifying a known-good DNS server.

But! I eventually noticed that adding the address of my local DNS server to /etc/resolv.conf did work - in the sense that DNS lookups in applications (presumably using the glibc stub resover) would succeed, but BIND tools like host and dig still don't. It took me a while to realise this given that my usual diagnostic tools for DNS issues are the things that are in fact broken.

I did try to investigate a little further, but I didn't get very far. I doubt this is illuminating, but just in case:

root@localhost:~# strace -e trace=network dig -4 +tcp archive.ubuntu.com @8.8.8.8 strace: Test for PTRACE_O_TRACESYSGOOD failed, giving up using this feature. socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 3 getsockname(3, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28]) = 0 socket(PF_LOCAL, SOCK_STREAM, 0) = 3 socket.c:1915: internal_send: 8.8.8.8#53: Invalid argument ;; communications error to 8.8.8.8#53: end of file --- SIGTERM {si_signo=SIGTERM, si_code=SI_TKILL, si_pid=1081, si_uid=0} --- strace: ptrace(PTRACE_SYSCALL,pid:1081,sig:15): Invalid argument Process 1081 detached

The thing that's confusing me is that AFAICT socket.c:1915 is only reachable as a result of "sendmsg(sock->fd, &msghdr, 0);", if it returns an error - but the strace doesn't show sendmsg being called at all, so I'm not sure what's going on.

Anyway, I'm moving on now, because it turns out there are alternatives: apt-get install knot-dnsutils knot-host replaces the BIND utils with the Knot DNS ones that work.

[robertsmieja]

Last night I tried editing the /etc/resolv.conf but all of my changes were reverted, didn't take effect, or had no impact.

Today I was able to run the following without any error or Windows updates :

lxrun /uninstall /full
bash
curl www.microsoft.com

I'm confident that this issue is now fixed and can be closed.

EDIT: Nevermind, it just broke. I have no idea why it worked temporarily. More interesting output:

root@localhost:/mnt/c/Users/Robert# ping 192.168.1.1
ping: icmp open socket: Socket type not supported

[Gingernaut]

I'm also running into the same issue on build 14316, bash is unable to do any commands that use the internet: curl, git clone, apt-get, etc. I allowed bash through my Bitdefender firewall but that hasn't solved it yet either.

[gdude2002]

@Gingernaut Allowing bash through the firewall is not good enough, you need to disable it entirely. The bash launcher is not the process that deals with networking, but nobody knows what exactly to allow at the moment.

[AndrewAndreev]

Big thanks to @thanosk. After adding a nameserver 192.168.0.1 (which is ip of my router), apt-get started to work correctly. So, I confirm bug with socket.c:1915: internal_send: 8.8.8.8#53: Invalid argument caused by incorrect generation of /etc/resolv.conf

[tommck]

I don't even have a /etc/resolv.conf file at all and running ifconfig gives me this:

root@localhost:/etc# ifconfig Warning: cannot open /proc/net/dev (No such file or directory). Limited output.

[AndrewAndreev]

@tommck, have you tried lxrun /uninstall and then lxrun /install?

[Gingernaut]

Turning off the firewall altogether resolved my issues, thanks @gdude2002.

[tommck]

@AndrewAndreev root@localhost:/etc# lxrun /uninstall lxrun: command not found

[gdude2002]

@tommck Do it outside bash, lol. You can't uninstall something you're using.

[tommck]

OK, I have no idea what lxrun is.. I guess it's the linux stuff.. makes sense

[tommck]

OK, tried that.. made no difference

[carloshm]

I got the same problem with connectivity. I edit /etc/resolv.conf and added first IP-router and voilá! Scenario was wired, /etc/resolv.conf created with DNS and local interfaces (HyperV), but not able to connect to internet. The problem is /etc/resolv.conf is changed during session, and permanent changes are not persisted #93

[tommck]

I even tried lxrun /uninstall /full and reinstalled.. same problem.

[dethoma]

Thanks for sharing. We investigated this issue and found that for machines where the first entry on the DNS list was an IPv6 DNS entry that lacked a route DNS lookup fails. Apparently glibc cycles through the first three entries in the resolv.conf file but this is only true when the nameserver returns success but zero records (doesn’t know how to resolve the name). We will work towards a more graceful solution here and post an update when we have a build with the fix released.

The reason manually editing the /etc/resolv.conf does not persist is because we recreate it during instance creation.

[boulund]

I got the same problem with connectivity. My /etc/resolv.conf was empty. Editing it and adding the line "nameserver 192.168.1.1" solved my issues with apt-get not working. Ping still not working.

[dethoma]

@boulund Can you please share your ipconfig /all with me? A completely empty resolv.conf indicates a generation bug on our side which is separate from the IPv6 issue I mentioned earlier.

The reason ping is not working is known, we have not yet implemented ICMP sockets. Given the general interest we will certainly look into this.

[boulund]

@dethoma Sure! Here goes:

Yeah I noticed ICMP sockets weren't working and saw other people's reports. No biggie for me really, I don't really need them. Ping is one of my first GOTOs for debugging network problems on Linux though :).

[ltd65]

On my system which runs bitdefender as AV and firewall it is required to disable the firewall completely to get a network connection from within bash

[Yas3r]

It is required to disable the Bitdefender firewall in order to get network connection in bash. However, ICMP packets are still not working.

Thanks

[ghost]

I believe ICMP ping won't work because raw sockets aren't supported.

use curl example.com as a better test of network connectivity for now.

[sn0wf1ake1]

Confirmed that if there's a IPv6 address in the first lines of the /etc/resolv.conf file then it doesn't automatically continue to the next DNS host.

and the generated resolv.conf was:

nameserver fec0:0:0:ffff::1
nameserver fec0:0:0:ffff::2
nameserver fec0:0:0:ffff::3

When i changed the content of resolv.conf to:

nameserver 192.168.2.1

wget, apt-get started to work but not ping.

and here is the generated /etc/resolv.conf on my machine :

nameserver fe80::1

nameserver fec0:0:0:ffff::1
nameserver fec0:0:0:ffff::2
nameserver fec0:0:0:ffff::3
nameserver fec0:0:0:ffff::1
nameserver fec0:0:0:ffff::2
nameserver fec0:0:0:ffff::3
nameserver fec0:0:0:ffff::1
nameserver fec0:0:0:ffff::2
nameserver fec0:0:0:ffff::3

I manage to get it to work by removing anything but the nameserver 192.168.100.1 line.

Hope this help :)
