[solved] Broken ping
Hi all, a recent update seems to have caused the "ping" binary to misbehave. Pinging a known good server on a known network now causes the time interval between each ping (after typing "ping google.com") to become sporadic and random.
I have two servers: server A, which I do not update frequently (maybe about once a month), and server B, which is updated daily or every other day.
The ping command on server A works as expected, but not on server B. Here is the full package list of each server:

Re: [solved] Broken ping
Can you provide examples of the timings please. I update 2 machines daily and I haven't noticed anything at all odd with ping.
Does anything else misbehave?

Re: [solved] Broken ping
I also find this highly unlikely. Are the network-connections of both machines comparable? Anything else that might be bogging down the system or the line? Maybe your iptables differ?

Nothing else seems to misbehave. The ping latency values themselves are correct, but the delay between each ping is sporadic.
For example, doing ping -i 1 archlinux.org actually behaves more like ping -i 5 (but a bit more random).

Network connections are exactly the same. Cat 6 cable to the same Ethernet switch. Tested with iptables with empty rules, exactly the same behaviour. There's next to no traffic on the Ethernet when tested, so it can't be the line getting saturated.
I've never had this problem before. Maybe it might be the Ethernet chipset driver. I'm using the r8168 module package from community.

Re: [solved] Broken ping
Okay, so you could run `tcpdump icmp`; tell us what the network-traffic looks like while ping is pausing. Alternatively use strace to check what is happening

Alright, so doing `ping -i 1 -c 4 66.211.214.131` works as expected. So something must be going wrong trying to resolve the name?
Doing `dig archlinux.org` is instantaneous.

Re: [solved] Broken ping
Yes; and another useful indication is this line which tells you what is on the other end of #4:
connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/avahi-daemon/socket"}, 110) = 0So have a look at your avahi daemon as it might be slowing down the resolving; which in turn slows down your ping

Fixed. I had to edit /etc/nsswitch.conf and change
hosts: files mdns [NOTFOUND=return] dns myhostnameto
hosts: files mdns_minimal [NOTFOUND=return] dns myhostnameThank you!
