Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : question about ssh and telnet

[matt2kjones]

ok if i create a user on redhat 7.3

and put that user in the group users

will they be able to login via ssh or telnet???

because i just want the users to be able to upload using ftp

thanx

actually, also, what exactly is ssh??? is it to allow people to use the command line of the server from a remote location???

as i dont want to be able to access the commandline away from the server so can i turn it off????

thanx

Set their shell to /nologin or /nonexistant
Allows ftp but not ssh. Telnet should be completely turned off.

[matt2kjones]

ok so is ssh and telnet the same thing???

they are currently set up as /sh

so can i stop sshd??? because i dont need it do i???

[matt2kjones]

ahhhh just looked

telnet is NOT running

i thought i remember stopping that a while ago.

[PHBPendragon]

telnet usually runs out of inetd and should be commented out.
If you turn off sshd I have no idea what it will break other than the ability to ssh in and fix things.

[matt2kjones]

because i can actually physically go up to the server, as in touch it, and login from the server itself, since its in my house.

its not at a datacanter or anything.

so do i need it running??? really???

all my users other than me are set to /nologin

so is there really any reason to stop it???

also it is also blocked by my dedicated firewall anyway, well, that is, if im correct when assuming that it runs on port 22

so really, if i can access the server physically if there is a problem, do i need ssh running??

thanx

If you can always get to the console, you can turn it off.
