Mac Address Generator For Stalker Client
Rocki Stenger
So, if you are building some kind of LAN based system and your clients are on the same ethernet segment, then you could get the MAC address by parsing the output of arp -n (linux) or arp -a (windows).
too late to answer but here is my approach since no one mentioned this here:
why not a client side solution ?
a javascript implementation to store the mac in a cookie (you can encrypt it before that)
then each request must include that cookie name, else it will be rejected.
to make this even more fun you can make a server side verification
from the mac address you get the manifacturer (there are plenty of free APIs for this)
then compare it with the user_agent value to see if there was some sort of manipulation:
a mac address of HP + a user agent of Safari = reject request.
Perhaps getting the Mac address is not the best approach for verifying a client's machine over the internet. Consider using a token instead which is stored in the client's browser by an administrator's login.
Perfectionism, with its burden of dysfunction, guilt and shame, is not always just a client issue. As therapists, supervisors and other human service professionals, we need to be self-aware if this stalker lives within our own mind and body.
Perfectionism, with its burden of dysfunction, guilt and shame, is not always just a client issue. As therapists, supervisors and other human service professionals, we need to be self-aware if this stalker lives within our own mind and body. We cannot help others heal if perfectionism has us by the throat. It will choke our compassion, patience and efforts to maintain a nonjudgmental approach. We also need to understand the importance of recognizing signs of perfectionism in our clients as it is often lurking in the shadows, not always obvious.
Make sure that the client computer has established the infrastructure tunnel: In the Windows Firewall with Advanced Security console, expand Monitoring/Security Associations, click Main Mode, and make sure that the IPsec security associations appear with the correct remote addresses for your DirectAccess configuration.
The second, more flexible, method is enabled by the secure_link and secure_link_md5 directives. Here the encoded string is an MD5 hash of variables defined in the NGINX Plus configuration file. Most commonly, the $remote_addr variable is included to restrict access to a particular client IP address, but you can use other values, for example $http_user_agent, which captures the User-Agent header and so restricts access to certain browsers.
The more flexible method for securing URLs uses the secure_link and secure_link_md5 directives. In this example, we use them to allow access to the /var/www/files/pricelist.html file only from clients on IP address 192.168.33.14 and only through December 31, 2016.
The secure_link_md5 directive defines the expression that is hashed to generate the MD5 value for the request; during URL processing, the hash is compared to the value of $arg_md5. The sample expression here includes the expiration time passed in the request (captured in the $secure_link_expires variable), the URL ($uri), the client IP address ($remote_addr), and the word enigma.
What do you do when your landlord is using a commercial ozone gas generator in a 43 unit building and first not telling a soul what
there doing allowing people to just live there caused the death of my Service Dog and damaged my lungs in my unit. Then HUD takes
2 years to investigate and makes the landlord fix many things but never addresses the toxic Gas , This is in units 4 years old.
The Access Rights are stored in one file for each domain, the Access.settings filestored in the Settings subdirectory of the domain directory. This makes it easy to check to whomthe Server administration rights are granted.Restricting Access If you do not plan to support mobile users, you may want to restrict access to the Server accounts. Use the following option on the Protection page: Grant Access to Clients Only When this option is selected, all Access (POP, IMAP, WebUser Interface, ACAP, PWD, etc.) connections are accepted only from the Server computer itself, and from the computers (network addresses) included into the Client Addresses list. When an access module accepts a connection from an unlisted network address, and this option is selected, the module sends an error code to the client application, and the connection is closed immediately. Links with the rest of the Internet will be used only for mail Transfer and access to Personal Web Sites. When this option is selected, the SMTP AUTH operation can be used only if a client mailer or server connects from the network address included into Client Addresses list. Note: Before you enable this option, make sure that the address you are using is included into the Client Addresses list: otherwise you will immediately lose access to the Server. You can also specify the access restrictions on the lower (TCP) connection level. For each service (module), open the Listener page and specify the addresses the service (module) should or should not accept connections from. If a connection comes from an address that is not included into the Grant list or is included into the Deny list, the connection is closed immediately, and no module-level operations are performed.Using SSL/TLS Secure ConnectionsThe CommuniGate Pro Server supports secure (encrypted) connection for all itsservices and modules. Secure connections can be established in two ways:
- A client mailer uses a special port to connect to the Serverand starts to establish a TLS (encrypted) connection right after a TCP connection withthat port is established. This method is used in Netscape and Miscrosoft mail clientsreleased before 2000. To support these clients with the CommuniGate Pro, configure the listeners for POP, IMAP, ACAP, SMTP, and LDAP modules: the Listenersshould accept TCP connections on those special ports (see the module descriptions forthose port numbers) and the Security option should be enabled for those ports, so theCommuniGate Pro server starts to establish a secure connection as soon as a TCP connectionto those ports is established.
- A client mailer uses a standard port to connect to the Server, and then issues aspecial (STARTTLS) command over the established clear-text TCP connection. When the Serverreceives such a command it starts to establish a secure connection. To support these clientsyou do not have to cofigure additional ports with the module Listener. At this moment, thismethod is implemented in the Netscape mailer only, and only for SMTP connections.
Many ISPs register the client's MAC address for service and billing services.[3] Since MAC addresses are unique and hard-coded on network interface controller (NIC) cards,[1] when the client wants to connect a new device or change an existing one, the ISP will detect different MAC addresses and might not grant Internet access to those new devices. This can be circumvented easily by MAC spoofing, with the client only needing to spoof the new device's MAC address so it appears to be the MAC address that was registered by the ISP.[3] In this case, the client spoofs their MAC address to gain Internet access from multiple devices. While this is generally a legitimate case, MAC spoofing of new devices can be considered illegal if the ISP's user agreement prevents the user from connecting more than one device to their service. Moreover, the client is not the only person who can spoof their MAC address to gain access to the ISP. Computer crackers can gain unauthorized access to the ISP via the same technique. This allows them to gain access to unauthorized services, while being difficult to identify and track as they are using the client's identity. This action is considered an illegitimate and illegal use of MAC spoofing.[4]
Quick post today showing some different ways to block visitors via their IP address. This can be useful for a variety of reasons, including stopping some stupid script kiddie from harassing your site, or preventing some creepy stalker loser from lurking around your forums, or even silencing the endless supply of angry trolls that never seem to get a clue. So many reasons why, and so many ways to block them. Continue reading to learn how to block any IP address using a thin slice of .htaccess.
The Internet of Things (IoT) is increasingly a reality today. Nevertheless, some key challenges still need to be given particular attention so that IoT solutions further support the growing demand for connected devices and the services offered. Due to the potential relevance and sensitivity of services, IoT solutions should address the security and privacy concerns surrounding these devices and the data they collect, generate, and process. Recently, the Blockchain technology has gained much attention in IoT solutions. Its primary usage scenarios are in the financial domain, where Blockchain creates a promising applications world and can be leveraged to solve security and privacy issues. However, this emerging technology has a great potential in the most diverse technological areas and can significantly help achieve the Internet of Things view in different aspects, increasing the capacity of decentralization, facilitating interactions, enabling new transaction models, and allowing autonomous coordination of the devices. The paper goal is to provide the concepts about the structure and operation of Blockchain and, mainly, analyze how the use of this technology can be used to provide security and privacy in IoT. Finally, we present the stalker, which is a selfish miner variant that has the objective of preventing a node to publish its blocks on the main chain.
