Unreferenced date July 2007 A reverse connection is usually used to bypass Firewall computing firewall restrictions on open port s. A firewall usually blocks open ports, but does not block outgoing Internet traffic traffic . In a normal forward connection, a Client computing client connects to a Server computing server through the server s open port , but in the case of a reverse connection, the client opens the port that the server connects to. The most common way a reverse connection is used is to bypass Firewall computing firewall and router computing Router security restrictions. For example, a trojan horse computing Trojan horse running on a computer behind a firewall that blocks incoming connections can easily open an outbound connection to a remote host on the Internet. Once the connection is established, the remote host can send commands to the Trojan horse. Trojan horses Remote Administration Tool s that use a reverse connection usually send SYN TCP packets to the attacker s IP address . The attacker listens for these SYN packets and accepts the desired connections. If a computer is sending SYN packets or is connected to an attacker s PC, the connections can be discovered by using the netstat command or a common port listener like Active Ports . If the Internet connection is closed down and an application still tries to connect to remote hosts it may be infected with malware. Keylogger s and other malicious programs are harder to detect once installed, because they connect only once per session. Note that SYN packets by themselves are not necessarily a cause for alarm, as they are a standard part of all TCP connections. There are legitimate uses for using reverse connections, for example to allow hosts behind a NAT firewall to be administered remotely. These hosts do not normally have public IP addresses, and so must either have ports forwarded at the firewall ... de Reverse Connection ... more details

In algebraic geometry and synthetic differential geometry , a Grothendieck connection is a way of viewing connection mathematics connections in terms of descent data from infinitesimal neighbourhoods of the diagonal. Introduction and motivation The Grothendieck connection is a generalization of the Gauss Manin connection constructed in a manner analogous to that in which the Ehresmann connection generalizes the covariant derivative Koszul connection Koszul connection . The construction itself must satisfy a requirement of geometric invariance , which may be regarded as the analog of covariant covariance for a wider class of structures including the scheme mathematics schemes of algebraic geometry. Thus the connection in a certain sense must live in a natural sheaf mathematics sheaf on a Grothendieck topology . In this section, we discuss how to describe an Ehresmann connection in sheaf theoretic terms as a Grothendieck connection. Let M be a manifold mathematics manifold and &pi E &rarr M a surjective submersion mathematics submersion , so that E is a manifold fibred over M . Let J sup 1 sup M , E be the first order jet bundle of sections of E . This may be regarded as a bundle over M or a bundle over the total space of E . With the latter interpretation, an Ehresmann connection is a section of the bundle over E J sup 1 sup M , E &rarr E . The problem is thus to obtain an intrinsic description of the sheaf of sections of this vector bundle. Grothendieck s solution is to consider the diagonal embedding &Delta M &rarr M × M . The sheaf I of ideals of &Delta in M × M consists of functions on M × M which vanish along the diagonal. Much of the infinitesimal geometry of M can be realized in terms of I . For instance, &Delta sup sup I I sup 2 sup is the sheaf of sections ... sup E with each other. A Grothendieck connection is a specified isomorphism between these two spaces ... Publ.
