[Bug 1414887] Re: dns query from localnetwork ignored
Ah, thanks Thomas. You lead me to the right direction. As Simon Kelley, the author of dnsmasq said in the new dnsmasq manpag, `local-service` is intended to be set as a default on installation, to allow unconfigured installations to be useful... it will have no effect, but for otherwise-unconfigured installations, it stops dnsmasq from being vulnerable to DNS-reflection attacks, I'm changing this bug report to bear the purpose to have dnsmasq better configured out of box for Ubuntu (14.10+). - First, as suggested by the author of dnsmasq, the `local-service` should be in the default configuration. However, Ubuntu 14.10 doesn't have that: % cat /etc/dnsmasq.conf /etc/dnsmasq.d/network-manager | sed '/^$/d; /^#/d' bind-interfaces - Second, unlike its previous version, Ubuntu 14.10 now starts dnsmasq in a very restricted way. Here is what I found out how dnsmasq is started in Ubuntu 14.10: /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind- interfaces --pid-file=/run/sendsigs.omit.d/network-manager.dnsmasq.pid --listen-address=127.0.1.1 --conf- file=/var/run/NetworkManager/dnsmasq.conf --cache-size=0 --proxy-dnssec --enable-dbus=org.freedesktop.NetworkManager.dnsmasq --conf- dir=/etc/NetworkManager/dnsmasq.d I.e., that ` --listen-address=127.0.1.1` will willfully ignore any dns queries from localnetwork. This is the exact reason causing the symptom that I reported. I believe this setting should not be there, because 1. for people that need the setting, it is very easy to put it into a conf file under /etc/dnsmasq.d/; 2. however, it will make it very very difficult for people who don't need it to get rid of it unless altering the package installation. 3. Ubuntu should really ship the default setting of `local-service` instead of `listen-address`, because it is a safer default and not invasive in the meantime. it will have no effect but for an otherwise-unconfigured installation. Please consider. Meanwhile, is there any better way to get rid of that ` --listen- address=127.0.1.1`? The least that I want is to altering the package installation.

It is not because of iptables rules either: $ sudo iptables-save | wc 0 0 0 I've installed dnsmasq on two different machines, one being freshly installed today, and both of them are showing exactly the same symptom.

[Bug 1395343] Re: Ubuntu 14.10 Utopic suspend/resume not working for my Laptop
This is a rarely used computer. I'm sure it is not disk errors, as it never gave any problem before, but failed to wake up the HD instead, each and every time that I tried. I got disk errors on other machines before, so I know what it means. I.e., if it is disk errors, the the error sequence reported above will be entirely different. No I can't use apport-collect, as it's function is to automatically generate crash reports for debugging. However my machine/SW does not crash, but freeze up entirely. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to pm-utils in Ubuntu. https://bugs.launchpad.net/bugs/1395343 Title: Ubuntu 14.10 Utopic suspend/resume not working for my Laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1395343/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1395343] [NEW] Ubuntu 14.10 Utopic suspend/resume not working for my Laptop
Public bug reported: The Ubuntu 14.10 Utopic suspend/resume is not working for my Laptop. I first tried with the Live CD, on failing that, and thinking that suspend might need some disk to write to for the suspend info, I did a HD installation. But still, suspend/resume is still not working. On second attempt (after HD installation), I switched to console and close my Laptop lid. It suspended well, as it has always been. On resume, I see the repeating errors of `sda1` soft reset failure (or something like that). Minutes later, I start to see all kinds of disk related errors, disk sector writing error, ext4 journal error, etc. I thus think the reason of `resume` not working is that the HD is not waken up. This is Acer Aspire AS5536, with XUbuntu 14.10 Utopic. Any more info that I can provide?
