rlogin, ftp, telnet
 

Hi all,

I'm having problems after installing linux 7.3

from my solaris box I can ping my linux box but I can't get logged into the linux box via rlogin or telnet. With telnet, it brings up the log-in dialog but even when I try to login as root it gives me a 'Login incorrect' message. With ftp and rlogin my connections are refused. I have amended the telnet file in xinetd.d to disable=no.

Any help would be really appreciated.

I don't think those services will allow you to log in as root. Have you tried it with a user account?

Yeah, tried and failed - it's only telnet that actually brings up a log-in dialog

Ok, are these services tcp wrapped? What does your inetd.conf file look like? Have you run a port scan to see if the ports are listening? What distro are you using? Ftp server? Why do I have more questions than you do?:)

incidentally, you may want to consider using ssh instead of telnet.

woah, woah, woah... slow down there...

firstly, you'll have to tell me what I should be doing in order to answer your questions..

you could be right about ssh but neither are any good to be if I can't get them working...

Sorry, I'm on my second cup of mate -- I'll try to take it easy.

Let's start with your distro and kernel version. You should now the distro straight off. For the kernel version, type 'uname -r'

I am curious to see if necessary ports are open. Nmap may already be on your machine. Simply type (as root) 'nmap localhost' Post the results. If you get a 'command not found' error, you need to get it and install it -- it's an invaluable security tool.

Just for fun, try this from your Solaris box: 'ssh IpAddressOfLinBox' and see if you can log in with a user account.

Cheers for bearing with me...

kernel : uname -r gives me 2.4.18-3

nmap:

Starting nmap V. 2.54BETA31 ( www.insecure.org/nmap/ )
Interesting ports on mack (127.0.0.1):
(The 1545 ports scanned but not shown below are in state: closed)
Port State Service
22/tcp open ssh
23/tcp open telnet
25/tcp open smtp

513/tcp open login

1024/tcp open kdm
1025/tcp open listen
6000/tcp open X11


Nmap run completed -- 1 IP address (1 host up) scanned in 1 second

ssh: requests the user's password but gives a 'permission denied' dialog when correct password entered


Any help?

So, you're login ports (22, 23, and 513) are all open, but ftp (21) is not. Most likely you don't have an ftp server installed/running. We'll worry about that later.

The user that is being denied remote access -- can it log in to the machine itself?

I'm probably misunderstanding you but if you mean if I can log into my linux box from the box itself then yes I can, I'm typing from my linux box....

...with a user account

Hey sknoxy, how you coming?

Sorry I disappeared for the weekend, have you worked it out yet? If not, I had another idea. What do your hosts.allow and hosts.deny files look like?
