I want to use my personal computer remotely. The problem is my computer is connected to a local network that I can't modify. I can connect from my computer to another one that has public IP via ssh. Is it possible to login to the "proxy" computer from somewhere and somehow use the connection established before to connect to my PC?
View 3 RepliesI am using Nautilus to connect to an external server. Currently, I use password authentication, and all works fine. I just type sftp://SERVER and the connection is established after providing the login credentials. However, I changed the server to only accept Public Key Authentication and disabled password authentication, and as a consequence I could not login using Nautilus anymore. Is there some way to make this work?

My Ubuntu server is now providing routing duties to my network, but I'm having trouble opening ports to my network. I have a DynDNS account, so the IP is always current, but I can't ping even my IP directly.
My network map looks like
Internet > SpeedTouch DSL modem with DHCP > eth1 > Ubuntu > eth0 > LAN
With the modem providing a 192.168.1.xx IP to eth1, I can browse fine. The default gateway is my modem. I switched to the public IP of the modem so I could use iptables for firewall duties, but I was locked out of the internet. No gateway was set when I did that, but eth1 received the public IP of my modem.
How can I use the public IP assigned to eth1?
I have two nagging problems on one network which I do not have on another elsewhere, both using uptodate Debian servers. The server is on the private subnet behind a router/adsl modem. The symptoms of the one which does not work
1) Users cannot access their web site from lan. If they try, they get to the router web interface, same as if they entered http:10.0.0.138 which is the router's lan address.
2) Users cannot access smtp or pop3 service using the domain name, they can access it only using the servers LAN address.
I fear that I might have not set up the router properly because appart from that the two servers are almost identical but I do not know where I might have made an error.
I'm sure this is possible... I'm just not sure how. Yet! I have three machines. One is at home behind my firewall and has a dynamic IP. That's fine as I don't really want to open any ports on my home firewall. The second is at work sitting behind the firewall there- and I'm not even going to ask for approval to NAT an IP to my PC at work :-).
The third is in a data center far away. I only have a shell account on this server but other than that shell account not being root, I can do most anything I like with that account. What I would like to do is SSH to this server simultaneously from my home and work PCs and, via this third machine, make them talk.
This is pure geekery so it doesn't matter what they say to each other; I just want to make them talk. Maybe one uploads a file and the other just pulls down that file. Maybe one opens a FIFO on the remote server and starts writing to it while the other starts snarfing that data. In fact, I like this latter idea best, I think. How would you do it? What scripts (fired by cron if need be since I'm ostensibly away from at least one of the PCs at any given time) would you use?
I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet. I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.

guest is ubuntu 9.04 server 64bit
Qemu : 0.11.1
Qemu manager: 7.0
from Qemu manager, if network card is using User Networking, it's a NAT and I can see that Guest Ubuntu has an ip address 10.0.2.15 and is able to access the internet. However, as Guest ubuntu is running server so I want to do use Tap networking and I assue with Tap, the Guest ubuntu will get an ip address which is in the same subnet as host machine by dhcp. so from Qemu Manager 7.0, I changed Network card to be:
NE2000PCI
Vlan Number =0
VLAN Type: Tap Networking
Mac address: tap0's mac address from host
TAP Network Adpator: Tap0
Note that tap0 was created by openvpn. and then fired Ubuntu guest, ifconfig shows no ip address on eth0 (which has the same mac address as Tap0) so the guest Ubuntu has no ip address and can't access public.
I have installed Linux Mint 8 (based on ubuntu). And I have setup a webserver on port 8098.
I can connect to my webserver with http://127.0.0.1:8098, but when I try to connect to http://192.168.1.107:8098 from the same machine or another machine it doesn't work.
How can I get this working? Is there any default firewall settings that I have to change?
I have one doubt that is how can we actually connect a system in private network with the system in a public network using IP address. I have one system in private network (in my campus) I need to connect it with the system on public network (home) using IP address and communicate with each other. How can I do it or is there any other way of connecting these two systems more easily?

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

View 14 Replies View RelatedIn Gnome Places->Connect To Server dialog, I am having problem using the Custom Location Service Type. I enter in the URI as
Code:

I get an pop up error message that says:
Quote:
Cannot Connect To Server. You must enter a name for the server.
Which would be fine if there was actually a place for me to enter the name which there is not. What am I doing wrong. This is the first time I have tried using the Connect To Server dialog. Normally I just use a script I wrote to mount my share in a folder on my local drive as some programs cannot access the mounted network folder. In a browser all I have to do is:
Code:
smb://ipaddress/share_name
I tried using Windows Shares, but that did not work either. It does work if I click on network and access the share that way, but some programs like firefox and a few others that I want to save a file to my network drive do not show the network unless the share is mounted in a folder. So, I wrote a script:
Code:
#!/bin/sh
#mount ext storage drive
mount -t cifs //192.168.0.2/files -o username="username",password="password" /mnt/files
This works and I can use this, but it would be handy if I could just use the Connect To Server dialog.
I have the opportunity to set up our local public library with a linux server. The primary need is for the server to land wifi users to a hotspot splash screen where they will accept terms of use and indicate what town they are from by checking a box or selecting from a dropdown menu. Users of terminals in the library would also have to indicate what town they are from. Things such as content filtering may come later. What distro would be recommended for this? Ease of use and configuration is important. They basically want to track use of the internet.

Run a script on ServerA which uses a ssh-connection to ServerB to execute a few commands on ServerB. As ServerB only allows login with username+password the whole stuff gets more complex. SSH provides key authentication enabling passwordless login as you probably know. So as stated in many tutorials I did the following:

ssh-keygen -t dsa
ssh-copy-id .ssh/id_dsa.pub osr@10.17.120.207

I've got a slight issue with logging into my server using public keys.
It was working fine, until I had to rebuild my desktop machine. I had the key copied to the server, and passwordless logins where fine.
However now I have rebuilt my desktop, I cant get to the login.
So heres whats happend.
Rebuilt id_rsa.pub, server will not allow login. Remove id_rsa.pub and the server allows password based login.
On the server, removed authorized_keys and known_hosts. makes no difference. Server still disallows keyfile, but will allow password when id_rsa is not present on the client.
Heres a -v of the login chat with keyfile
Code:

So, is there anyway of getting the server to forget the previous keys, it is remembering, As previousily said, I have completly removed the contents of ~/.ssh/ on both the clients and the server.
How would you assign a server a public static IP ?
Ok.. I guess to better ask my question... how to assign server public static IP centos? Like for example I am in the router itself.. where would I go to point ip 44.33.33.21. to ?> 192.168.1.4
What would be the most common in the routers?

How do I move the contents of /public-back/templates recursively with permissions into /public/templates ?
