Telnet

[Anjaneyulu]

Hi, I need to know about these things

Telnet,rlogin,rcp,rsh,ssh,scp

Which daemons are must running to login these commands?

If you have any document Please forward me.

[Laurent Menase]

telnet, rlogin, rcp, rsh it is inetd with
the following services

telnet -> telnet starting telnetd
rlogin -> login starting rlogind
rcp, rsh-> shell starting remshd
rexec -> exec starting rexecd

for ssh/scp it is sshd which is the daemon

[OldSchool]

ssh / scp rely on the Secure Shell package being installed and configured, and sshd must be running on the destination.

Telnet requires telnetd be up and running in the destination.

rlogin requires rlogind be runing.

Note:
generally, if ssh / sftp / scp are installed, then telnet / rlogin / rcp and remsh would be disabled.

Refer to the man pages, /etc/services and /etc/inetd.conf for more info

>>Telnet,rlogin,rcp,rsh

check in /etc/inetd.conf

>>scp,ssh

check in /etc/opt/ssh/sshd_config

[Laurent Menase · Accepted solution]

docs are:

man inetd
man inetd.conf
man telnetd
man rlogind
man remshd ( for rcp and remsh since both are using remshd)
man sshd
man sshd_config

everything is above
what other type of info are you looking for?
