Starting Telnetd

[djrose]

I'd like to set up a remote connection to my Pandora, but I'm not too familiar with Linux.

What are the options for doing it? I tried starting telnetd, but was told it "Cannot possibly work without effective root".

I then tried doing an su, but don't know the password.

Sorry if this sounds dumb, but I've done a search and not managed to find an answer.

Thanks.

You should use SSH, as that is already setup and working on the Pandora. Also, Telnet is unsecured.
You can use a tool like Putty if you're on the PC.
Just ssh to your Pandora and login with your name

people still use telnet? :blink:

 

[PhillipJ]

I use telnet all the time at work. Don't think the version of Vxworks I deal with has ssh.

So the Pandora has a SSH server running by default ??
Isn't that a bad idea with people using no or relatively insecure password.

Installing / enabling a SSH Server should be easy but I don't think it should be running by default.

 

[djrose]

Thanks for the replies. I'll give ssh a try.

Out of interest, and just carrying on with one of my questions, what would the password be for su? Or is it of no use?

I highly doubt there is a SSH server running. But a SSH client is installed by default of course!

Well the original question was "to set up a remote connection to my Pandora"... but your're right this need clarification.

I don't think sshd is running by default - refer to the ps ax from laurens post (ps ax result)

 

[mQQm]

Yes, mine seems to have an SSH server running out of the box. Funny there also seems to be an http server (port 80) running as well.

(edit)

I may have started the http server myself.

That listing clearly includes Dropbear, though.

odd - apache httpd? could you do a ps of the running processes and post them here. thanks.

 

[mQQm]

Yep i must of started the httpd server while I was mucking about. Its gone after a reboot. Here's a PS anyway.

oops - you're right - too used to heavyweight linux distros. Looks like ssh access is enabled by default.

 

[WizardStan]

That listing clearly includes Dropbear, though.

I did not notice that the first time through. It is extremely risky to run an SSH daemon if you have no interest in it, and especially so to leave it on the default port. The word "stupid" did cross my mind for a moment. At the very least it should be an opt in with the setup wizard.

Agree 100%

It's not like ppl aren't connecting their Pandora to the Internet / Public Network

default port is not really the big the issue here IMO... it's just:

-You shouldn't run an SSH server if you don't need it

-If you're running it you should you should:
- Use a Strong password for your account
- (OR/AND) Configure a passkey for authentication

 

[sebt3]

-If you're running it you should you should:
- Use a Strong password for your account
- (OR/AND) Configure a passkey for authentication

I'm using no password at all at home, nor will I on my P.
But I'll have sshd running (ssh key pairing ftw)

 

[WizardStan]

In general yes, I meant in this specific case. If you're going to have something active by default without telling the user how to shut it off, leaving it on a commonly attacked port just adds to the risk.

I personally would still put a password on the Pandora default account (same as any linux distro).
Doesn't mean you shouldn't use auto login though.

Key pairing is great for SSH

Did anyone notice that the process was running twice? What's with that?
