VT100 emulator on Win7 to Linux Virtualbox

[JohnSmith]

Hi,

I am using Windows 7 as host, and I have Linux Red Hat running on VirtualBox. I would like, from Windows, to use any vt100 terminal emulator to connect to Linux. I have already changed the network to bridge, but even though, I am not able to access Linux environment, so, does anyone know how to solve it?

tks.

Have you got any error message?
Which emulator have you try? I suggest to try PuTTy.
How would you like to access your linux? Via SSH? Telnet? Serial port or something other?
IMHO you try to use ssh. If it's true, then...
- sshd is running?
- it is listening on the bridged interface?
- which user did you use to login? If you tried to login with root, then you must to allow root login in sshd's config.
- what's with linux firewall? If enabled, it can deny to use ssh..
etc...
Could you give some details?

Hi H.Z,

I am not an expert in Linux, so, let me see if I can answer your questions:

Have you got any error message? --> no, I have no message, but I have no access as well.
Which emulator have you try? I suggest to try PuTTy. --> I am using Putty.
How would you like to access your linux? Via SSH? Telnet? Serial port or something other? --> could be ssh or telnet, what it works first, or what I dont have to change many things in Linux....
IMHO you try to use ssh. If it's true, then... --> yes, I tried to connect to Linux using ssh and telnet, however, it is difficult to knwo the correct IP address. I used ip addr eth0, and I used the first IP that I saw after this command......
- sshd is running? --> yes, it is running....
- it is listening on the bridged interface? --> how do I know that it is working....the internet is being sharing.....
- which user did you use to login? If you tried to login with root, then you must to allow root login in sshd's config. --> I didnt type any user, because there is no prompt to do it,..I think the connection is not completed.....
- what's with linux firewall? If enabled, it can deny to use ssh.. ---> it is enable, but telnet and ssh are set as reliable...


if you have any hints, please let me know....

tks.

Could you ping the guest?

it is difficult to knwo the correct IP address. I used ip addr eth0, and I used the first IP that I saw after this command......

Ahh...
Start the VM and...
(I assume, you use only one virtual network adapter on the guest)

version one:
- login to guest as root (or other user, then su -, or sudo -i)
- ifconfig eth0
This will show parameters of interface eth0.

version two:
run cmd.exe on host, and
VBoxManage guestproperty enumerate "guest name" | find "Net/0/V4/IP"

- it is listening on the bridged interface? --> how do I know that it is working....

Login to guest, get a root shell, and run "netstat -lntp | grep ':22' "
You should see something like this:
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 777/sshd
If you see 127.0.0.1:22 instead of 0.0.0.0:22 then try to reconfigure sshd to listen on all interfaces. (I don't know, how can you do it, because I use debian based systems)

- what's with linux firewall? If enabled, it can deny to use ssh.. ---> it is enable, but telnet and ssh are set as reliable...

If the above hints don't help, then try to temporarily disable firewall on linux!
