@strugee They're different fields. IT security folks generally couldn't design a cipher (well, at least not a secure one). Cryptographers (who are often mathematicians) probably couldn't configure an enterprise firewall (at least not correctly).
I find the manuals very difficult to read using the terminal. Is there a way to highlight specific text on the terminal? I tried piping to gedit using man man | gedit, but it opens a blank file instead.
Perhaps there's some way to find text within a man page and have it highlighted?
@Braiam - via meta: "...Now, notice that this is subtly different from saying "If that other question isn't asking the exact same thing as yours..." That's because the proof is in the answers. If the question looks the same, but the answers aren't solving the asker's problem, that is not a dupe – that is a legitimate new question. Neither the person asking nor the person who lands from Google cares if the question has been asked before: they care if it has been answered...."
I feel like we got off on the wrong foot. Due to me being an idiot miscommunication, a partial change snuck out early, and even though we announced it we didn't really explain why we made the change. So let me just start over...

How can you discover who is connected to a wifi network near you? (you not being connected to it).
I know that some tools can scan your own network, and that some tools like Wireshark can monitor packages (and you can see the MAC addresses of these packages). But what I want to find is a tool t...
You can use the tool fing (you'll have to install it) to see all the clients on the network. It won't show structure, just connectivity.
To see what's accessing what you need to use a monitoring tool to collect this data on the host that it's passing through. For example if you have a router/switch that is acting as a NAT for your entire network, you need to collect the data there or periodically collect it from that host and store it somewhere else.
I have installed wine and i am afraid that viruses will affect my PC now. I will not open any other .exe file other than mine one (which i use everyday)

@Dew don't spam people in chat. if you think you'll have a better chance on U&L, flag for migration. when you simply post questions in chat it makes us want to help you less, not more
@slm But the dupe question didn't give me an answer. Is it regardless (in your opinion) equivalent in some sense? I don't know sed. And moderators can be wrong. :-)
@Dew - if you post Q's here I'll make sure to ignore them, esp. if you continuously do it! Also you asked your new SU Q a while back here and it was marked as a dup. I left a comment on your SU Q about this. What do you want with this Q? HINT BE MORE SPECIFIC!!!! YOUR Q IS VAGUE AND MAKES FOR A DISCUSSION, NOT ROOTED IN FACTS OR DATA!!!!
@FaheemMitha - maybe let's tear your Q down more then. What exactly did you want that wasn't addressed in the dup? The title of the dup and the A's seem to be what it sounds like you want: "...Inserting text at the beginning of a file with sed via the terminal in Linux..."
@slm Yes, the title of the other question is the correct topic, but didn't contain my answer. I'd prefer to have it reopened so I can add my answer - currently at the end fo the question.
I actually don't understand why the working solution worked.
@FaheemMitha - I voted to reopen it. We'll have to ask around here to get others to do so as well. I reopened mainly b/c you had a working solution that you wanted to post and it wasn't available on the other Q nor would it have made sense to add it to that one.
@slm Right. Actually, both questions are examples of a more general question which it probably impossible to answer in general. Can you explain why my answer works, though? Just curious.
So I know umask can restrict privileged users, using this format umask ugo.
I understand that the read = 4, write = 2, and exec = 1. However, when I type umask, it returns 4 digits which is 0022 or 0073. I have no understanding of how does this work now because there is an extra digit. What is t...

@strugee - that guy can be a jerk, just a heads up!
This kind of crap is what he pulled with me: "why do you not recommend changing the program version? I changed it yesterday to 1.5.5 and it worked.. and I've changed it from the changelog file.. so what about this debian/control file that you are talking about??"
We aren't mind readers, I deleted my A to his Q and we voted to close it, it was a weak Q anyway and I was being nice, he came back and was giving me hell for not suggesting that he use find to find a file on disk or some garbage.
apparently our avatars say we're mind readers, I must be blind, cuz I didn't see it on mine 8-)
"I guess you are wrong about the control file.. it has no version numbers or anything.. I'm just gonna try the changelog file since most of articles out there say that its first line is what determines the package release and version numbers and I guess they are right because I've tried it once and it worked. So I guess it's better to delete that part in your answer.. Ciao! "
He comes across as a know-it-all but is the one asking the Q's and then pulling that tone with us when we provide him with our understanding of it. I'd avoid him, he bites
Another example: "@Totor I figured out that too late. I mean people here can be very misleading. It should have been obvious to them that both have same version. so it was like I did nothing.. Regarding security, my site is just a personal blog, and i guess nginx security holes are way complicated for an ordinary hacker to exploit. so i'll have enough time for that.."
" I accepted your answer as because at least you were the most helpful and concise but I urge you to at least put an example of pinning this particular package since your link is very useless at pointing that out. Looking forward to your edit. Thanks – Dr.SMS""
I would not engage him unless you're in the mood to get criticized for trying to assist. You've been warned.
In general most people on these help forums are less appreciative than one would like. For example, most people don't say thanks, even when accepting an answer.
@FaheemMitha - yeah I don't care if there isn't a thank you but the backhanded comments are unnecessary, ppl here are learning and trying to help too. Plus no one is getting paid to be here, it's voluntary.
@Seiyria - you're quite welcome. Thanks for the Q and hope to see you on our site in the future. Good luck with your foray into Linux! — slmJan 14 at 18:33
Thank you for the in-depth example. I learned a bit more about linux today! — SeiyriaJan 14 at 18:29
@strugee there was a fair amount of discussion about this, and there was a sort-of concensus that the CTTE members could be trusted to rise above such things. :-)
But I don't think humans are so lofty in practice. People like to think they are, perhaps.
Do you guys think systemd is better than upstart?
I've corresponded with Russ a bit, and by reputation he is one of the sanest people on the planet, as well as being pretty nice, so I'd tend to trust his opinion.
Some people thought Ian Jackson's post was rubbish, but I could not really judge.
Determine you exposure
Taking your output from the netstat command, what looks like a lot of services is actually a very short list:
$ netstat -lntup | awk '{print $6 $7}'|sed 's/LISTEN//'| cut -d"/" -f2|sort|uniq|grep -v Foreign
avahi-daemon:r
dhclient
dropbox
nmbd
rpcbind
rpc.statd
smbd
sshd
...
When researching this Q there were basic things that you couldn't do around getting the status of services in upstart that seemed ridiculous that they weren't avail.
mostly I like systemd because it's so simple to write services. I haven't yet gotten the hang of robustly parsing arguments in bash scripts yet, so systemd service files are much easier to read and modify than Upstart scripts
e.g. if you don't have a single native systemd service file on your system, systemd will find all the shell scripts that you had for initialization and use them. if those scripts have Upstart or LSB headers, systemd will use that info as best it can. it's very clever
@FaheemMitha I feel the exact same way (see: Upstart on other distros, Mir, libnotify... the list goes on). that's why I don't touch Ubuntu systems anymore
the systemd journal is also a very cool replacement for syslog
I find the manuals very difficult to read using the terminal. Is there a way to highlight specific text on the terminal? I tried piping to gedit using man man | gedit, but it opens a blank file instead.
Perhaps there's some way to find text within a man page and have it highlighted?
