Re: [EXTERNAL] Canceled do-release-upgrade

2019-03-19 Thread Armindo Silva
Hello Leroy,

Probably not all packages were downloaded/installed.
Depending on where you were on the upgrade process the Crtl-c may try to
reverse the install.
You can use the livecd to boot/chroot into that installation, check if your
apt config is pointing to xenial repositories (something like grep
xenial /etc/apt/sources.list should output several lines) and then try to
finish it: sudo apt update + sudo apt dist-upgrade.

Re: [14.04] KVM Windows 2008 R2 Guest, Fica lento inexplicavelmente

2014-07-15 Thread Armindo Silva
Hi Serge,

Disabling KSM appears to solve this - I disabled it a couple of hours after
receiving your email and I haven't had a network problem since then.
Although not mandatory KSM is a nice feature to have, is there anything I
can do to help sort this out? Is there a bug report related with this or
should I open one?
Thank you for for help.

Best regards,
Armindo

Re: [14.04] KVM Windows 2008 R2 Guest, Fica lento inexplicavelmente

2014-07-08 Thread Armindo Silva
The version of the qemu package on that ppa is older than the one currently
on trusty repos.

I have a similar problem, I updated a host from 13.10 to 14.04 and since
then some of the virtual machines have been experiencing network connection
problems - the connection freezes and pinging them goes from a couple of ms
to several seconds. I made some preliminary tests like changing the network
devices to and from virtio but the problem still persists.
Rebooting the virtual machines solves this for a couple of hours.

Any ideas/pointers?
Thank you.

Regards,
Armindo

[Bug 1196887] [NEW] Virtio-9p Failed to initialize fs-driver with id:fsdev-fs0 and export path: my path

2013-07-02 Thread Armindo Silva
Public bug reported:

I am trying to add a filesystem (add new virtual hardware, filesystem)
using libvirt's virt-manager to a guest and when I try to start the
guest it fails with the following message:

virsh # start images
error: Failed to start domain images
error: internal error Process exited while reading console log output: char 
device redirected to /dev/pts/4
Virtio-9p Failed to initialize fs-driver with id:fsdev-fs0 and export path:my 
path

I found this old bug report on debian:  http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=674919 and it appears that a similar bug was
caused by a mismatch between the glib versions used to compile the
package and available on the system.

 all other users can read and execute.
 755= same as above, but group can only read and exec.

 777= all users on your machine can do anything in files/dirs set with
 this acl. Remember, even if you are the only physical user on the
 machine, all processes (apache, ftpd, postfix, etc) are users on your
 machine and will be able to do bad stuff if 1) the code is buggy and
 happens to try to delete everything, or 2) if the process gets owned
 by evil hacker eddie.

 Thanks!
 Michael

[Bug 379329] Re: Security flaw in openSSH prior to 5.2

2009-05-22 Thread Armindo Silva
It appears that there's no need to backport a new version of OpenSSH. As
you can see here: http://www.openssh.com/txt/cbc.adv you only need to
add this line:

Ciphers aes128-ctr,aes256-ctr,arcfour256,arcfour,aes128-cbc,aes256-cbc

to ssh_config and sshd_config and restart the daemon.
Also:
The severity is considered to be potentially HIGH due to the
32 bits of plaintext that can be recovered. However, the 
likelihood of a successful attack is considered LOW.
