[17:52] <starspot> how do I set up an ssh tunnel so I can connect to this home Ubuntu machine from a remote location?
[17:53] <mhall119|work> starspot: is it behind a firewall/
[17:53] <mhall119|work> ?
[17:57] <starspot> mhall119|work, no. just a comcast modem and a linksys router
[17:58] <mhall119|work> is the linksys doing NAT?
[18:02] <starspot> I don't know - what is NAT?
[18:03] <mhall119|work> it's where inside your network, you have IP addresses like 192.168.x.x
[18:03] <mhall119|work> but on the outside, the router has a public IP address
[18:04] <mhall119|work> which makes it hard to access your internal computers from the outside internet
[18:07] <starspot> yes I do have 192.168.1.100 ...1.200 etc
[18:07] <mhall119|work> then you're using NAT
[18:07] <mhall119|work> which means you can't connect directly to your home machine from a remote location
[18:08] <starspot> what if I remove the router?
[18:08] <mhall119|work> there's better ways
[18:09] <mhall119|work> one second, let me find you a tutorial
[18:09] <mhall119|work> http://www.howtoforge.com/reverse-ssh-tunneling
[18:09] <starspot> thanks man!
[18:11] <mhall119|work> np
[18:35] <starspot> hey mhall119|work : that tutorial's pretty complex. if the problem is NAT and it's in my Linksys, couldn't I just remove the router and then tunnel more easily directly to my IP?
[18:37] <starspot> or anybody else?
[18:38] <starspot> If I connect directly to a cable modem will SSH Tunneling work so I can access this machine remotely?
[19:03] <mhall119|work> starspot: the NAT is useful and offers some level of protection to you, so I wouldn't recommend removing it
[19:04] <mhall119|work> another options is to setup port forwarding on your router, so that incoming connections to port 22 are sent to the Ubuntu machine you want to connect to
[19:55] <starspot> I already got around the NAT issue. I'm ssh'd in to my box now, with the router
[19:55] <starspot> mhall119|work, yes - I used port forwarding on the router
[19:56] <mhall119|work> okay
[19:56] <mhall119|work> just make sure you either use good passwords, or public key authentication only
[19:56] <grayghost> I am looking for help with telnet ....??
[19:57] <mhall119|work> what kind of help?
[19:57] <grayghost> I am trying to copy a file to a dd-wrt router and can't make copy work
[19:58] <mhall119|work> does dd-wrt use ssh?
[19:59] <grayghost> it can ... but that look harder.
[20:00] <mhall119|work> it's safer, and make copying easier
[20:00] <grayghost> but I should learn ssh ...   I thought telnet looked easer
[20:00] <mhall119|work> there's not much difference from a user perspective between ssh and telnet
[20:01] <mhall119|work> but if you use ssh, you can use scp to copy files to and from dd-wrt
[20:01] <grayghost> so do I log on the router with ssh insetad of telnet
[20:01] <grayghost> or do I use ssh from the ubuntu shell
[20:02] <mhall119|work> you need sshd running on the routher
[20:02] <mhall119|work> then you ssh from the Ubuntu shell to the router
[20:02] <mhall119|work> ssh username@routerip
[20:02] <mhall119|work> should get you a shell on the router
[20:02] <mhall119|work> scp $localfile username@routerip:/path/destfile
[20:03] <mhall119|work> will copy $localfile to /path/destfile on the router
[20:04] <grayghost> I don't understand username@routerip
[20:04] <mhall119|work> okay, did you create a user account in dd-wrt?
[20:04]  * mhall119|work isn't familiar with dd-wrt setup, sorry
[20:05] <grayghost> i am on the router now..... wirless
[20:05] <mhall119|work> did you install dd-wrt?
[20:08] <grayghost> yes I have it installed and working ... I am trying to copy acm.o to the router to set up mobil internet on the phone.
[20:09] <grayghost> the wiki tells me what to copy ..but not exactly how.
[20:12] <grayghost> I have the file on a usb drive which is avalible on the router ... i can see it with telnet ... but cp will not work on the router
[20:14] <grayghost> I am installing sshd now   and will try that
[20:18] <grayghost> no joy :-X
