Sleep and an Ethernet connection

Thank you for reading this.

One annoying problem that I've yet to resolve is the dropping of the 
Ethernet connection after waking from sleep. I occasionally had the same 
problem with a wireless connection on my laptop but that was easily 
overcome by pressing the "connect" button. There isn't a "connect" 
button in the "Active connections" box after waking on the desktop 
computer. The "Active connections" box is blank until the computer is 
rebooted.

A Google search has shown that this is a common problem. A few 
workarounds have been offered, however, none have worked for me. How 
have other list members overcome this problem?

Ghost gethost attack

I just read in a security tade journal about the "Ghost" attach.  I 
seems that it stems from the glibc library.  I was surprised that not 
much was mentioned about since the security concerns were announced in 
January, 2015.  It seems that Ubuntu 14.04 fixed the issue but 12.04 did 
not.  Between that I did not see clear documentation.

My question: Can I just check the date of the glibc file on my computer, 
and if it is not of a certain date, then replace it?  My issue is that 
some of my computers are running 14.04, but one is not, and I am unable 
to upgrade it, as when I did, things stopped working and it moved the 
prior version to a different filesystem, from which I use the computer.

tia,

John

So? If they can give it the 3 finger salute, they can also power it off when the bios screen comes back around.

CUPS question

I'm sorry if this is a dumb question, but I don't know enough about
CUPS to know. I have a utopic machine that acts as a file and print
server, and I need to set up a print client. The problem is that my
printer requires a binary-only driver that I can't run on the client.

Is there any way to set up CUPS with the driver only on the server, or
does the client also always need that driver?

I'm guessing that the client also needs it, but I would be very glad to
be wrong. :)

shutdown by regular user

How can a non-privileged user initiate a shutdown.

There is one person with an administrative account and sudo 
privleges.  There are 3 others with no account.  Frequently, in 
case of emergency shutdown the admin user is not available.

I would like to set up a regular user but make it possible for 
that user to run shutdown. In Unix I would use asroot, but Ubuntu 
14.4 LTS does not have that.

How can I do this.

Disable Routing Cache on Ubuntu 12.04.5 LTS

Hi,

I am using Ubuntu 12.04.5 LTS and have a couple of static routes on it.

The IP Address is 192.168.10.23 and the default gateway is 192.168.10.1

I added a couple of static routes to it so that it reaches a particular IP address using a different gateway

route add -net 10.24.78.0 netmask 255.255.255.0 gw 192.168.10.99 dev eth0

​This seems to work for a few days and then suddenly it forgets that it is supposed to use the different gateway to reach that ip address. It instead uses the default gateway

So instead of going through 192.168.10.99, it tries reaching 10.24.78.x through 192.168.10.1

The static route is still in place (verified by netstat -rn). The route table has not changed.

I did a "ip route flush cache" and this brought things back to normal.

So my question is, how do I disable this caching permanently? If this is not advisable, what are the other options?

I tried setting /proc/sys/net/ipv4/route/max_size to 0, but this value default to 214748364 on reboot.​
​If not mistaken, this sets the max size of the cache?

Disk partition

Hi,

Can a disk with free space be partitioned inside the OS even if the disk is in RAID or does this need to be
partitioned during install process?

Linux Hardware Problem sata 3 ASM-1061 PCIe x1 expansion card

I purchased a PCIe expansion card x1 Sata 3.0 controller with the
ASM-1061 chip on it. In windows it works fine. However in Linux after
boot up USB 2.0 ports do not work on the computer. I made sure I have
the latest BIOS update on my motherboard. 

Anyone have any experience with this on the mailing list?

Connectivity Problem..

Sirs,

I use my mobile phone (Vodafone 2G) to access internet on my laptop
(Dell Vostro 1015) as i was using Ubuntu 12.4 for long and only now i
have upgraded to 14.4.LTS.

the problem is i am not able to get connectd thru bluetooth as
whenever i am trying to connect thru mobile phone i get message "
unable to pair with Ubuntu-0 "

so when i am trying to pair thru my laptop i get message Error:
connection refused (111)  or sometimes the message says;
successfully setup new device (my Nokia 6120 classic) and after that
it reads.. detecting phone configuration and after a minute or two the
following messages appears;
Error: timed out detecting phone details.

i am not able to get connected as i was earlier so please guide me
what to do for getting connected successfully.

Thank you.
