Networking :: Ssh To Computers On LAN From A Proxy That Has Public IP?
Apr 13, 2010
I have a PC which has a Public IP.It is a webserver but it is not a proxy server.I want to be ableto do an ssh to the machines which are behind this webserver on LAN in one step.Right now I do an SSH to this webserver and then do an SSH to any other machine on my LAN how can I do it in one step.
I wish all of my Internet connections will go through a proxy server. HTTP as well as FTP, and every other type of link. How can i do that? On top of that, is there a free ubuntu-users' public proxy list?
Currently my DHCP Server is working now what i want to have is auto detection of squid proxy in any browser but I still got an error in my dhcp server when I restart it.
My Config:
# DHCP configuration generated by Firestarter ddns-update-style interim; ignore client-updates;
At the moment I have a proxy and all the users have to configure it in the browser to access internet. I want to make the users able to browse even without configuring the proxy in the browser. but eventually it should be received in the proxy rather than giving an error to the user. I heard with transparent proxy I can redirect all the traffic from a particular network, to a particular host( ie my existing proxy).
I tried this using firewall rules. But then the existing proxy doesn't understand the protocol of the requests. I heard that it should be in the kind of proxy protocol.
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
The following errors show up when I run from the file from the term window, but are not written to log.log:
tar: /public/public/clamscans/*.txt: Cannot stat: No such file or directory tar: Error exit delayed from previous errors mv: cannot stat `/public/public/clamscans/*.txt': No such file or directory
I know with windows you can add the 2>&1 to capture error data. Is there such a thing for Linux?
I've setup squid proxy st time on centos 5.This is my current setup.squid.conf:Quote:acl our_networks src 192.168.10.0/24 ttp_access allow our_networksQuote:
internet -- modem -- Firewall --switch--squid proxy (192.168.10.100) --client workstation ((192.168.10.200) (client workstation is connected to the same switch as the squid proxy)
How can I forward all traffic from a public IP to another public IP. Let's say I have a first debian box named box1 with eth0 = 1.1.1.1 and eth0:1 = 1.1.1.2 and I want to forward all traffic from 1.1.1.2 to "box2" located somewhere else over the internet and having for eth0 2.2.2.2 Both 1.1.1.0/24 and 3.3.3.0/24 are public IP ranges.
im trying to connect two computers on lan.One computer has: VMWare Workstation and has Opensuse 11.3 mounted in it.The other computer has: VMWare Player and has Opensuse 11.3 mounted in it.Both computers are connected to a switch with cables.I have followed this guide in both computers:Depanati singuri calculatorul!: Opensuse 11.3 - configure local networkin order to setup a network.In one computer, if i go to: Computer---Network---Network folder, i only see one machine. When in fact i could see both of them right
I am having a heck of a time trying to find directions on networking my two computers together in order to share files. I have two machines running Ubuntu 10.10 Desktop & Netbook remix.
They are both connected to my wireless router to connect to the internet.
I set up an SSH server on my home machine and finally figured out that I needed to disable password authentication to get RSA authentication enabled. Now I'm having problems with that too.ssh -v -i id_rsa ashtray@x.x.x.83
Code: OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8o 01 Jun 2010 debug1: Reading configuration data /etc/ssh/ssh_config
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?
I recently purchased a block of 5 IPs from Comcast. I have a computer running Arch Linux connected to the Comcast gateway they gave me. On my connected computer I have 2 Windows XP virtual machines running. Now I was wondering how can I make each of those virtual machines have a different public IP, because currently the only thing I can get working is have the computer and both virtual machines sharing the same public IP.
i am working at a place that has 2 physical web servers yadayada1 and yadayada2 but only one public ip address i can use dyndns to register 2 dynamic domains on the same ip address how can i get yadayadayada1.dyndns.org to route to yadayada1 and yadayadayada2.dyndns.org to route to yadayada2 ?
from the router it split into 2 connection one to my GW (linux debian) and another to a switch which is connected to a web/email server and the gateway.
My gw use x.x.x.27 and x.x.x.26 (everything I use on these ips is ok)
on the web/email server I have x.x.x.28 29 and 30
With this setup it's ok but I want to eliminate the link to the switch and make it pass thru the GW and i can't manage to get it work!
My web server public IP is: 202.1.2.3 and it was natted to internal IP 172.16.1.31 just confusing why I am unable to browse http://202.1.2.3 from LAN? (I able to browse http://172.16.1.31 from LAN)
As waht it says above. I can't access public wifi as any browser on every single distro i've tried (15+) won't load just stuck in perpetual loading. No error message or nothing.
Also the browser wouldn't work until i disabled ipv6 in about:config. All browsers do this. is there something i could do to disable it completely so i have a browser choice?
I'm trying to connect to my Xubuntu box (zelda) remotely using my RSA key. I'm using Cygwin on my Windows box (link) to SSH in to the Xubuntu box. I've created the key and placed it in the authorized_keys file on my remote box. Here's where it gets weird. When I ssh into zelda the first time, it prompts me for my password. However, if I'm already connected to zelda and try to open another connection, it prompts me for my RSA passphrase. This is very confusing, and I have no idea what's going on.Here's my sshd_config file on zelda.
Code: # Package generated configuration file # See the sshd(8) manpage for details
After years with Linux and using ssh on a daily basis I have to admit I've never setup public/private key authentication and I've never run passwordless logon to ssh. It's not that I've never tried, I have - I've just never got it working. That to me is an almost alien concept as I am a tinkerer at heart and rarely stop until something is working the way I'd like it to. I get the principle of what's going on but I've always had a mental block about it.
I've been searching for a while in forums about the issue I'm facing but couldn't find anything clear, or at least my net search skills are pretty lame. I'm facing a problem with prompted user password in a SSH chain connection when using authorized_keys.
I have: (1) Client - (2) Server - (3) Testing machine (testing machine is connect to Server via usb network)I've created keys for Client and Server, and updated authorized_keys in host machines with the key values: Testing machine has Server public key, and Server has Client public key.Until now everything is fine, if I try to connect via ssh the user password prompt is not shown since public key is found in authorized_keys.
For example: from Client: Code: ssh server Works fine, no password prompt.from Server: Code: ssh testing_machine Works fine, no password prompt.But if try to do that from Client only: from Client: Code: client:$ ssh server Works fine, no password prompt.from Client: Code: server:$ ssh testing_machine Asks for password.Bellow the verbose output from previous ssh command:
Code: ssh -v root(at)192.168.100.2 OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to 192.168.100.2 [192.168.100.2] port 22. [Code].....
does somebody know how dnsmasq / iptables need to be configured such that requests to my public IP from lan are correctly NAT'ed to the host that handles them? Currently my routing device treats them like "oh, these are anyway for me, gnam gnam" which actually doesn't work.Unfortunatly setting up NAT rules that redirect requests from my lan correctly as they are redirected from wan is an option I would like to use only if there is no other possibility.I would like some kind of solution that treats packets that are sent to my public IP as normal packets that are not looped back before they even get out. So they would need to be at least sent to the wan gateway where they are directed back where my firewall can successfully treat them like all other public requests.
I want to do some basic web hosting, mainly for the experience. I have verizon fios for my isp, and what i am wondering is can i have the public ip address that they give me when i connect out to the internet point back to my linux box?
The reason that i am asking this is because i want to register a .com and i would like to have that point back to my linux box, i have looked at a few services and it seems that godaddy.com will do this and they seem to be the best choice. Before i register the .com i turnd on my httpd server but i am not sure how to get the public ip point back to my box...?
I have been doing some research and i am learning about things such as
ddclient openvpn port forwarding nat dynamic dns
Verizon fios like most isp's uses a dhcp connection meaning that the public ip address i get will change 1-2 a year. What i don't know is how can i setup my network at home preferably with iptables to have that public ip routed back to my linux box at home? I am using fedora 15 for those that are wondering...
Also when i enabled port forwarding and started my web server and tried loading http://mypublicipaddress in firefox i am directed to a verizon page with a login and password prompt.
I am aware that i will need to get certain information from my isp to have their public ip address routed back to my linux box but i am unware of what to ask them...?
If anyone here can tell me the following i will be so happy because it seems like a lot to hosting at home but i really want to learn...
here is what i need to know?
1) What kind of questions and information do i need to ask and get from my isp? DNS info? Logins and Passwords?
2) What do i need to do on my linux box to have that public ip address routed back to my linux box at home?
3) What rules do i need to add to my iptables script to allow this, i know there are certain nat rules that need to be added and port forwarding is needed as well..
4) anything else you can think of that i need to do...
I'm updating many servers blacklist manualy. from time to time. I want to create a blacklist and host it on a website, and servers will update from this list regularly. For servers I'm using:
Centos iPcop Smoothwall
And for proxy I'm using Squid. And I dont use squidguard.
I have a strange problem and I can't seem to find clear information on how to do this . I have 2 loadbalancer set up keepalived NAT mode with 2 interfaces each
i have a commercial ISP connection with 5 IP addresses available and i want the following configuration note when i say domain group i am refering to a group of top level domains (not subdomains) owned by the same entity (company) with their A records pointed at the same public IP for a single server
