How do you scan the IP addresses for a certain open port with nmap?

Kadir last edited by

Using nmap, I faced a problem: when I scan the range of IP addresses for a certain open port with nmap, I get a lot of information: closed, open and filtered ports. I don't need information on closed and filtering ports, but I need only open ports and IP addresses where this port is open. Write what team I can use for this. It would be ideal if the information were to come in such a form, if that was possible: Discovered open port 12345/tcp on 94.75.2.5 (e.g.) Discovered open port 12345/tcp on 94.75.2.10 (e.g.) Thank you.

Use the grep, remove the lines that begin with 'Discovered'
```
nmap 10.0.0.0/24  -Pn -p 22  -v | grep 'Discovered'
```

Both of those NAC products use Gratuitous ARP, not answering to the who-has packets to win the race.

Problem solved. Port is available on a local network and no additional booth dance. It's just that the server was listening to localhost, not 192.168.x.x.x.

Round robin's not his fault. The address is one.213.242.253.81 is being resinsulated from several places quite successfully and uniformly. First, make sure the hosts file or the bottom of the local case servers didn't contain a line like that. 172.16.0.8 uapa.ru And then start screaming the service provider.

They can set up a packet sniffing program such as Wireshark to intercept all communications. As long as the websites you visit have an https - you're protected. As for apps and other things, try to find out if they use TLS encryption. Even with encryption/https they can see what IP addresses you connect to. If you don't set up your own DNS settings (with DNS encryption) they can see what domains you access. So if you type in google.com they can see your device made a DNS request for that but that's it they cannot see what you do on Google. Perhaps you may be interested in using a VPN

I don't know if the library socket allows that.An alternative is to read the report ifconfig with io.popen("ifconfig"):read"*a".If you know the interface name, then you can use that name in the call ifconfig.Unfortunately, the format of the report ifconfig appears to depend on the platform: they are different in Linux and Mac OS X.

If you want to use only HTML it is possible using accesskey, but in this case it is necessary to tighten alt, how alt+s would be:<a href="https://google.com" rel="noopener noreferer" target="_blank" accesskey="s"> ^^^^^^^^^^^^ But if you just want to click s (or any other key), without the alt, should use JS, using a simple EventListener. You can test below an example, click "s" and a page will open.window.document.addEventListener("keydown", function(e){ if (e.key != "s") { return } window.open("https://pt.stackoverflow.com", "_self"); })O https://developer.mozilla.org/pt-BR/docs/Web/Events/keydown will be triggered whenever a key is pressed. So if key equal to s it will open the page.

This you want to do, it is not possible to do only with DNS. DNS only resolves addresses, not ports. To redirect HTTP to another port, you need an HTTP server. We then have two alternatives. If the subdomain address (123.45.678.90) is with port 80 free (which I do not believe is the case, otherwise you would not want to use port 8180), you should place a web server answering on port 80 and redirecting any request to http://subdominio.meusite.com.br:8180 .If the subdomain address (123.45.678.90) is already using port 80 for the main domain (I believe it is your case), you must enable the use of Virtual Host on port 80 server, because there a single Web server can serve multiple domains in the same address. In a virtual host you place the domain, in the other virtual host the subdomain that redirects everything to :8180.The virtual host configuration varies according to the web server you are using, so I will not enter details.

From further research, it appears the issue may be a result of older SQL clients performing an "InstanceValidity" check when connecting to SQL Server (specifically sqlsvr32.dll driver). The driver passes "MSSQLServer" as the instance to verify for the InstanceValidity check. In this case, since the instance name listening on the Default port (1433) is named "Instance1", the check fails because the Instance names do not match the InstanceValidity check. Specifying the port number or instance name explicitly in the connection string works.

There's a concept of a default gateway. In fact, the existence of it means, "if you don't know the route to the destination send it to the default lock."In addition to the default route, the Router may also know specific subnets. For example, a homewalker usually only knows his inner cell to which the user devices are connected. All the rest of it, he's throwing it on the locker. The homewalker may also know about the inside network of the provider, but it usually ends with his knowledge.And there's a lot more of "know" players. If you do not enter the internal routing of the service provider ' s network, it may be easier to say that the router knows about all the inside subways of the service provider, as well as the sub-networks of other providers that he has direct connections (so-called Piring). As strange as it may be, most providers also have a default lock that leads to a higher-level and larger-scale service provider (so-called aplinc, uplink).But! Tier-1 providers are located at the top of the network. Their routers don't have a shut-down lock. They know where any IP address is. Tier-1 providers are connecting the network, which means connecting any two white IP addresses. Of course, the equipment of these providers doesn't go any way compared to the usual housewives.It should be added that if we know where the destination is, that is, the address of the Router that he is behind, it does not mean that this target source is the only one. In fact, the Router's address is tied down, i.e., a continuous group of addresses (or several groups) that serves this router (so-called prefix). There may be a group of others behind this route, each of which only serves part of these addresses. For example, a service provider may set a route to the area and have one general nature combining regional subnets. This structure allows for aggregation of addresses, reducing the number of prefixes at the plinkov level.So when your home computer in Volgograd wants to get a page from the site in Mexico, it's sending a bag to the homewriter, the one on the provider's router, the provider-- his pinnacle, and so long as the package doesn't reach the provider who knows where the Mexican web site is (i.e., the address of the Router for which it is located). The package goes further through a chain of routers, followed by increasingly small subnets and finally reaches the right site. A similar process is taking place when the site sends you an answer.

The answer is quite possibly, it depends on how the proxy is configured and the networking works. The key to answering this question is the line about the IP address of aaa.com being accessible using telnet or nmap. As this is the case, we can assume that traffic to the site is not being blocked completely. For example assuming the proxy is blocking based on hostnames it sees (e.g. aaa.com) and not based on other factors (e.g. the IP address) if it doesn't see a blocked address it may not block it. If you give aaa.com a different address using hosts (which generally takes precedence in name resolution over other mechanisms), the request will go to the web server with that alternate name. Now the webserver may not respond as it will get a request for a host it doesn't recognise and may not respond well to that, or may redirect back to aaa.com which would cause the proxy blocking to kick in. What we don't know from the question is whether the requests using telnet or nmap were bypassing the proxy and therefore that's why they could get to it, in that circumstance it might not work. To provide an example, say we're trying to block www.google.com. If you put a line in /etc/hosts specifying one of www.google.com's addresses being www.flooble.com, and then make a request to www.flooble.com and intercept the request with a proxy, what you see is a request to www.flooble.com on the IP address mentioned, with no mention of www.google.com. So if the block is purely based on the hostname, it won't kick in. Now we know from the question that connections to the web port on that IP address are successful, so it's possible that the connection would work. EDIT - One other factor to consider, which would be important in this case is "where does the name resolution occur". In some cases with an explicitly configured proxy the name resolution occurs on the proxy, in which case the request wouldn't work. In other cases with a transparent proxy (i.e. the client browser isn't aware that it's using a proxy) the name resolution would occur prior to the proxy seeing the traffic, in which case it would seem from the question that the request would work.

Only if 2 or more endpoints are to be provided for different machines. For example, REST API and EPP API may be separate in different machines or for any other need. It's true, and it's possible to put it in ports, but that's what I want, I want and I cry, I cry, and I'm doing it.

VLAN:s are not inherently insecure. I'm writing this from a service provider perspective, where VLANs are the technology used in 99% (statistics made up on the spot) of cases to segment different customers from each other. Residential customers from each other, residential customers from enterprise leased lines, enterprise VPNs from each other, you name it. The VLAN hopping attacks that exist all depend on a few factors; The switch speaks some kind of trunk protocol to you, allowing you to "register" for a different VLAN. This should never, ever occur on a customer port, or someone should get fired. The port is a tagged port, and the switch isn't protected against double tagged packets. This is only an issue if you have customers on VLAN-tagged ports, which you shouldn't. Even then, it's only an issue if you allow untagged packets on trunk ports between switches which, again, you shouldn't. The "packets travel on the same wire" reasoning is valid, if the attacker has access to the physical wire in question. If that's the case, you have a lot bigger problems than what VLANs can solve. So, by all means use VLANs as a security measure, but make sure that you never, ever speak VLAN tags with the entities you want segmented from each other, and do keep track of which switch features are enabled on ports facing such entities.

To answer your questions: If someone could breach your wireless security, they may be able to sniff everything going across your wireless network. You may think this is only a small risk, however, if this traffic includes any usernames or passwords which are not further encrypted, then those might be at risk - which would weaken security further. If they could gain access to an account on the wireless access point itself, there is potentially a wider risk of compromise of the connection into your network. I wouldn't necessarily buy an analyser if you have an iphone, laptop or other mobile device as you can get free applications to do exactly this In terms of the question itself - it is arguable how much security a quarterly scan will give you; it really will only spot permanent wireless devices or ones that happen to be on at the time you are scanning. however, to get your PCI-DSS checkbox you had best do it anyway. As @AviD says: PCI compliance reduces the risk of the penalties of non-compliance
