resolv.conf broken on ubuntu system

0 votes
367 views

At some point that I sadly cannot identify, /etc/resolv.conf stopped being created/updated by network manager on my Ubuntu 12.04 system. The system gets an address via DHCP, and the network works just fine if I use IP addresses or if I manually put a suitable DNS server address in /etc/resolv.conf, but /etc/resolv.conf is not updated automatically any more.

I have watched the DHCP exchange with wireshark. The client requests everything it should, and the server responds with everything it should (domain, gateway etc); I see it all arriving at the eth0 interface. But /etc/resolv.conf change th not. Nor is it created anew if I simply delete it.

The problem survives a restart of Network Manager, and a complete reboot,

Is "/etc/resolv.conf" a symlink to "/run/resolvconf/resolv.conf"?

Does resolvconf run at boot? (It runs and exits so "ps ..." on a running system won't determine whetehr it's run.)

How to obtain list of installed packages on Ubuntu System?

I believe that this question gets asked from time to time, but I do not know that a solution has been found.

The question is this; does a utility exist, that can be ran, to produce a list of installed packages, in a way that can be used by a user (system administrator), to perform a system rebuild, so as to, after installing the system again, ensure that all of the optional packages that were previously installed, are again installed in the new system installation?

I am running UbuntuMate 15.10, on a system with other Linux operating system versions (which are inappropriate for the hardware), that are not used, installed, and, with wanting to eliminate them, and, repartition the HDD, for a number of reasons, including occasionally seeing an error message that states that the partitioning is out of alignment, or something (I am not sure of the exact message, or, how to reproduce the error message), I believe that a new installation of the operating system, is needed, but, I want to again, have all of the existing installed optional packages, installed and operable.

So, I figure that, if a utility exists, that can produce a list of the installed optional packages, that could help me to reproduce the system, with its current functionality, in terms of the currently installed, optional packages.

how/where umask is defined on a Ubuntu server system

I am wondering how - or more exactly where - umask is defined on a stock Ubuntu server system.

I have reactivated the root account. Here's the respective default umask for root and normal users:

Nomal User:

$ umask
0002

Root User 

$ umask
0022

On RHEL/CentOS, these values are defined in /etc/bashrc and then in the individual ~/.bashrc files. How does Ubuntu handle this?

ethernet bonding and NFS on ubuntu system

I'm facing some trouble setting up a 13.04 server (amd64) which I want to use Ethernet bonding and NFS mounted volumes.

I've read the ubuntu tutorial about Ethernet bonding but seems the machine try to mount NFS volumes BEFORE the network comes up , the result is the volumes are not mounted at boot up.

Please help.
