I figure ip tools thinks I'm attempting to set something on the interface. Anyhow, your "ip l l" shortcut appears (see my manpage comment below) to evaluate to "ip link list", which is awesome! Shortcuts for the win. On a CentOS 6.6 system per the ip manpage, it seems that "list" is undocumented for link and addr. (Certainly correct me if I'm wrong ... I did find a TLDP page with an example of "ip link list", so it's known by some.) Thanks Mike. I use Ubuntu on the laptop and in the manpage for the ip command it has the following: COMMAND ...*As a rule, it is possible to add,** ** delete and **show (or list )**objects, but some objects do not allow all** ** of these operations or have some additional commands.* ... Seems to be vaguely documented - I can see how *(or list )* part can be misleading as you might think they are just saying that show _will_list_ and not necessary that *list* can be substituted for *show* - it's all in the wording! Oddly, the man page for ip (iproute-2.6.18-13.el5) on CentOS 5 is way more comprehensive (it has way more examples on where list can be used) than that on Ubuntu 14.04.1 with iproute-3.12.0-2!

Indeed it is quite easy. In you ${HOME}/.screenrc file, add the following:

This would change your escape sequence to CTRL+Z. I had to do something

He reckoned that for a man with his temperament (he is quick to anger and is rather well built), he would end up in a maximum security joint for sure. I ended up siding with him in that it would be better to invest in a monitored security system and ensure there are enough signs around the premises to alert any personnel in the B&E business to stay out! Below excerpt taken from [0]: Data shows that homes with monitored security systems are up to three times less likely to be broken into than homes without them. If you have a security system, be sure to: * Install the stickers and signs, so you can let the would-be burglar know your home won't be an easy target. * Test your system often to make sure it is working properly. Security equipment manufacturers recommend testing your system at least once per month. * Keep your key holders list updated, so you can be easily contacted in the event of a break-in. All of these things can help you prevent a burglary from happening to your home. Benjamin Franklin once said, *"An ounce of prevention is worth a pound of cure."* This rings true when it comes to keeping your home safe and secure. That's my $0.02.

[CentOS] Layer 2 VPN with OpenSSH on CentOS7 not working!
Hi all. I'm trying to bring an Amazon VM into the LAN by following this guide [0].

CentOS5/6 gives me: ** tap1: mtu 1500 qdisc noop state DOWN qlen 500 link/ether 9e:9e:44:9e:49:4c brd ff:ff:ff:ff:ff:ff CentOS7 gives me: tun1: mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 500 link/none So, what's broken in 7 - or is it that it requires something different?

Hi folks.
Just wondering if I can change the ownership on the nginx logs folder so I can

/var/log/nginx is owned by nginx:nginx which shuts me out.
Cheers, Bee
Here's a twist to the other provided solutions. I find it easier to
leave permissions as they are and instead use ACL's. That way, I can
remove the ACL's (# sudo setfacl -b /path/to/dir) and not worry about
what the original permissions were.
This is how I'd sort it out:
First, I'd create a default ACL (this will allow new files in the
directory to inherit the ACL):
# sudo setfacl -d -m u::rwx /var/log/nginx
Next, I'dd apply the ACL to the directory:
# sudo setfacl -m u::rwx /var/log/nginx
Finally, I'd ensure that I can access existing files in that directory:
# sudo sh -c "find /var/log/nginx -maxdepth 1 -type f -exec setfacl -m
u::r {} \;"
Caveat: I use EXT4 so not sure how this would play with other file systems.
