Comproportionation or symproportionation is a chemical reaction where two reactants, each containing the same element but with a different oxidation number, will form a product in which the elements involved reach the same oxidation number. Potassium permanganate contains manganese with oxidation number of +7 and reacts with a manganese compound having oxidation number +2 to yield manganese(IV) oxide (manganese dioxide) with oxidation number +4, potassium hydroxide and water.
Secure Shell, or SSH, is a cryptographic (encrypted) network protocol to allow remote login and other network services to operate securely over an unsecured network. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.
by admin. SSH1 vs SSH2. SSH (Secure Shell) is a protocol which is used to enable security to data communication over the networks. SSH was found by Tatu Ylonen (SSH Communications Security Corporation) in 1995.SH-USERAUTH: It is the protocol used for user authentication at the communication establishment. This protocol authenticates SSH client in SSH server. This protocol also runs over the transport layer. SSH-CONNECT: It is the connection protocol which multiplexes encrypted data into some logical streams.
