install mininet only

Hello,

I want to install mininet only, I did the following command but I faced an error.
I do not want to remove the existed openvswitch

alghada <at> kw12067:~$ sudo apt-get install mininet/precise-backports
Reading package lists... Done
Building dependency tree      
Reading state information... Done
Selected version '2.0.0-0ubuntu1~ubuntu12.04.1' (Ubuntu:12.04/precise-backports [amd64]) for 'mininet'
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 mininet : Depends: python-networkx but it is not going to be installed
 openvswitch-controller : Depends: openvswitch-common (= 1.10.0-1) but 2.3.1-1 is to be installed
                          Depends: openvswitch-pki (= 1.10.0-1) but 2.3.1-1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

If you compare the kernel package changelog of 3.16.0-31.41 with 
3.13.0-46.75 you'll see that it has the same patches* that solved the bug 
#131811, but they're applied to a different bug report for some reason.

*"xen-netfront: Fix handling packets on compound pages with skb_linearize" 
and "xen-netfront: use correct linear area after linearizing an skb"

HP 1020 Printer issue

Some strange entries in my syslog pertaining to my printer

http://pastebin.com/xGfnztcz

the current kernel is 3.13.0-46-generic #77-Ubuntu SMP Mon Mar 2
18:23:39 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux, seems like the printer
will not initialize during the boot process as it used to in previous
kernel versions. As shown below in my sig this is Ubuntu 14.04.2 LTS.
Any ideas?

SSD and Ubuntu FDE

Hi

I am about to purchase a Crucial BX100 120GB to replace my HDD. I read
that it doesn't provide hardware acceleration for Full Disk Encryption
(FDE). Should I be concerned (in terms of performance) about such a
matter, given that I am indeed planning to use the default LUKS FDE
(as is the case for my current HDD) and the PC is used for word
processing and spreadsheets (no gaming, video editing)?

Thanks!

Fix for dropped packets on EC2 included in 14.04.2 LTS, 3.16.0-31-generic ?

Hi,

I'm not sure how to confirm if this bug fix [1] was included in 
Ubuntu 14.04.2 LTS, 3.16.0-31-generic ?
I didn't see this bug listed in the 14.04.2 release notes [2] and it looks to have been fixed recently but lists the fix as verified and included in 3.13.0-46.75

perforrn internet function on a schedule

My internet service provider limits my throughput but allows free access 
from midnight to 05:00 in my time zone.  Sometimes I need to get 
upgrades, etc. which are large.  Is there a way to schedule net 
functions, such as downloads to certain hours.  I understand (sort of) 
cron, but I see that for command sequences in bash.

Run from thumb drive

  Hi all, I am using Lubuntu   ( Navigatrix)  on a computer to navigate 
a sailboat with.  At the present time I have a laptop for navigation 
that I do not use on line and I have one that I use on line. I am afraid 
that my navigation computer might be compromised and cause me to run up 
on top a coral reef. Home file is incripted. I am being told that IF I 
use the program running off a thumb drive that it will be safe from 
compromise because it can't be written to?    What do you guys think 
about this does it make sense. Doug

Dual embedded Broadcom Gigabit1 NICs 5721J; 
Optional single and dual port Intel PRO/1000 PT Gigabit adapter (copper); Optional single port, Intel PRO/100S; 
Optional single and dual port Intel PRO/1000 PT (PCI Express); 
Optional Broadcom NetXtreme™ Gigabit adapter

Any ideas?

Looking for a life-save LVM Guru

Dear All,

I am in desperate need for LVM data rescue for my server.
I have an VG call vg_hosting consisting of 4 PVs each contained in a
separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1).
And this LV: lv_home was created to use all the space of the 4 PVs.

Right now, the third hard drive is damaged; and therefore the third PV
(/dev/sdc1) cannot be accessed anymore. I would like to recover whatever
left in the other 3 PVs (/dev/sda1, /dev/sdb1, and /dev/sdd1).

I have tried with the following:

1. Removing the broken PV:

# vgreduce --force vg_hosting /dev/sdc1
  Physical volume "/dev/sdc1" still in use

# pvmove /dev/sdc1
  No extents available for allocation

2. Replacing the broken PV:

I was able to create a new PV and restore the VG Config/meta data:

# pvcreate --restorefile ... --uuid ... /dev/sdc1
# vgcfgrestore --file ... vg_hosting

However, vgchange would give this error:

# vgchange -a y
          device-mapper: resume ioctl on  failed: Invalid argument
          Unable to resume vg_hosting-lv_home (253:4)
          0 logical volume(s) in volume group "vg_hosting" now active

Could someone help me please???
I'm in dire need for help to save the data, at least some of it if possible.

Regards,
Khem
