Please use a search engine before posting:


Honestly, if every one that wanted to know what a certain IP is, asked here, ....ridicules, I know, some technical questions do not all ways get good results, and sometines people do not understand what they read in the results, so that is what the forum is for. But asking us to look up a IP :!: :

Here is a example, in a effort to help the OP learn how to look up a IP, and find out what it is :
What is 224.0.0.1?
First hit: https://en.wikipedia.org/wiki/Multicast_address
A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (layer 3 for OSI) for Internet Protocol Version 4 (IPv4) or Version 6 (IPv6) multicast.
Please try to learn how to use a search engine. Thank you , and have a good day,...
P.S. Also the 'whois' command is useful, 'man whois',.....example:
Code: Select all
 $ whois 224.0.0.1

Comment:        Addresses starting with a number between 224 and 239 are used for IP multicast.  IP multicast is a technology for efficiently sending the same content to multiple destinations.  It is commonly used for distributing financial information and video streams, among other things.

Ah, You again.
I had asked you to ignore my questions in another thread.

Do you work for this forum? (This is the only reason I can think of).
If so,
Please let your boss know I asked you to ignore all my dumb questions.

I thought a forum is a place to exchange information and even gossip.
Don't answer if you don't want to.


ALL Forum stuffs,
I really dont know why I have all theses Dumb questions sometime.
There is absolutely not need to answer if you are not having fun to answer them.

No, I don't work for anyone or anything,.....But I don't want to ignore them, I find them humorous, this is a public forum, any one can read anything they want, and respond to any posts as well. You could just ignore my answers/responses if you don't like them.. Or you could just try to find the answers , before asking, then no one would be calling you a help vampire...The members that do help all are volunteers, and do help a lot of people, it just gets "under my skin" when I see this kind of abuse, probably just asking questions to boost your post count,..I don't know, maybe a bot , a mindless one at that..who knows ? Who cares ?

Don't answer if you don't want to.

Yes it is, all though this forum is not intended for gossip, and foolish play questions that some one asks just to boost the post count.
I do want to answer, I enjoy it, I enjoy sharing demos and examples about how to search, and sometimes, find a answer for some one,... I did show you 2 methods, that you could have used to find a answer, and Head_On_A_stick, also asked you to start using a search engine, he also gave you a link, that has the answer as well , yet it never even occurred to you to say thank you! Another trait of help vampires,

Help vampires can be cured, if the person is willing to improve their selves, and most are not only willing , but want to improve, want to become better members.... I am starting to really wonder about you, I suspect you are a very young person, maybe about 12 years old, spoiled brat that thinks they are entitled to everything on a silver platter, still to young to comprehend the idea of actually do a little work for yourself, instead of all ways needing someone to hold your hand, ...I mean , yes the forum is for technical questions, and technical answers, but it is not intended for silly "boost my post count" questions, and google is excellent for finding out what a specific IP is for, who it is, and even more,... we use the IP information to block hackers,spammers, and other "bad boy's", we can use google to find out if a certain IP should be blocked, ....you are asking about a Firewall, and using Iptables , you need to learn how to look up IP's and see what they are, even on a PC you will see many IP's, all communicating with your PC, or modem, yes I know, there is a lot to learn, but just like most of your other questions, there is also tons of information that experienced people are willing to share, and have made the effort to make that information available to you, Why don't you take advantage of that ? Did you even try :
Is it worth to set up a firewall for PC? The results can be enhanced if you include Linux in the string,...try it, and let us know what results you think are the most useful,..
Other tech help forums, also do not like help vampires very much, it is not just me, nor this forum only, I am trying to help you become a better person...for your own good, you will be proud of your self when you show your self and others you actually are able to find answers, and solve problems, on your own,...
Also, and I will close with this, you really should read it:
What we expect you have Done
Look at the date :by Absent Minded » 2009-11-20 20:37
Indeed I really am trying to help you, I enjoy it very much, I do not do anything if I don't enjoy it..usually any way, sometimes we all have to do things we have to do, even if we don't really like to, getting online, and passing time on a forum is not something I have to do, it is something I like to do, when I have the free time and nothing else to do,...now I have put a whole lot of time and effort into writing this, it was fun, but it has gotten to long, and I am tired, so it is not so fun any more,... I hope it helps you, and/or others stop being a help vampire, and become better person , more useful contributors... not just on this
forum, but even out side, in the real world , at work...etc. Anyway, have a good day, or night,... and try to learn how to do searches and use the databases for your benefit, it is much more rewarding then needing to sit and wait for a hand out, and hand holding nanny, learn how to crawl, before trying to walk, when you are ready, stand on your own 2 feet, and walk, no need to wait for a nanny to hold your hand, ...blah blah , bla blah,...good nihght ZZZZZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzZZZZZZzzzzzzzzzzzzzzzzzzzz

Also I agree with H_O_A_S:
And as I told you before don't bother with iptables, it's obsolete.

This gives details and explains why,...
https://wiki.debian.org/nftables
Should I build a firewall using a nftables?

Yes. Building new firewalls on top of iptables is discouraged.

Should I replace an iptables firewall with a nftables one?

Yes, nftables is the replacement for iptables. There are some tools in place to ease in this task.


Is it worth to set up a firewall for PC?

My opinion, no, there really is no need, using the default settings:
nftables in Debian the easy way

If you want to enable a default firewall in Debian, follow these steps:

Just enabling the default fire wall is all I need, so why bother with complicating things,KISS, . but someone else might have different requirements. If one has more requirements, then I suppose it is worth the extra hassle, or for someone that just enjoys making things more complicated then need be.

Wow, cuckooflew, coffee much? :lol: I agree with what you say however.
Personally, a forum is usually the last place I will try to find answers and only when all else fails. Most questions have an answer somewhere on the internet already and a search engine will find that answer in a fraction of a minute. Much better than waiting hours or days for a forum reply.
I try to ignore help vampires. If a question is obviously something for which an answer can be found with a simple search, I just don't answer it.

8) Ignoring is the best policy, especially when it's obvious no effort was made to search or read the manual or help menus first.

https://www.darkreading.com/who-invente ... id/1129238

Runs down the birth of the firewall concept at Digital. History is interesting and sometimes prescient. No one really knows who came up with term "firewall"... so maybe there is no such thing.

Wow, cuckooflew, coffee much?

Actually I think so, I don't usually drink coffee in the evening , or night,..usually milk, but for some reason last night, I was going to have a evening snack, chocolate chip cookies, and milk..but I got a craving for coffee, made with hot milk.... and it hit me pretty strong, I was up until 2am, and for someone that usually wakes up a 5am, 2am is very late, I slept in a little, but had to get up at 7,...any way...yea , it was the coffee. But I don't regret writing all of that, guess that will be my rant for this week,...
