Networking :: Using A Public-Facing SSH Server To Broker A Connection Between Two Clients?
Feb 22, 2010I'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?

Networking :: DMZ - No Communication Between Server And 2 Clients
Oct 28, 2010Code:
DMZ
Server--Router0--Modem0 ISP2--Modem3--Router3--Client3
/
Client1--Router1--Modem1--ISP1--WAN
/
Client2--Router2--Modem2 ISP3--Modem4--Router4--Client4
The Server in the above diagram can be accessed by Client3 and Client4 but not at all by Client1 or Client2. Router0 specifies the Server as a DMZ Host. I would be more specific but this is not my server. I don't use a DMZ, I forward ports when they are needed. In this case I represent ISP1 and the server belongs to a befuddled client. Client1 & Client2 can send packets to each other, no problem. Could the DMZ be breaking communication between the Server and Clients 1 & 2?
Fedora Networking :: F10 As Server And Clients Are WinXP
Jun 21, 2009I'm setting up a network for a school. The network has 11 client computers (windows xp) and a server (fedora 10) All I need to do is have a share for all the children to use. (this I did by adding each client to the workgroup specified on samba then I just map the drive). The issue turns out to be that I have over 300 users. The users don't always use the same computer therefore I need the users to be registered on all 11 clients. How can I do this? I have been searching and I've not gotten anywhere. How can I add the computers to a domain instead of a workgroup? What can I use?

Ubuntu Networking :: VPN Server Does Not Allow Clients To Access Internet?
Jan 7, 2010i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.
i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.
here is what my setup looks like:
Code:

CentOS 5 Networking :: Can't Seem To Get The X Server To Allow Access From Clients On Other Hosts?
Jan 8, 2009I can't seem to get the X server to allow access from clients on other hosts. (I know, not exactly a network problem, but. I made the change in /usr/share/gdm/defaults.conf to be : DisallowTCP=false
and this worked on another CentOS system, but it hasn't fixed it on this one. What other things could prevent other clients from connecting to the X server? From the local host, I get :
Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed although the client DOES actually create the window and work! So, maybe this message is a clue.
From the remote host, I get : Error: Can't open display: 10.10.1.20:0.0 Which is not terribly informative. Is there a log somewhere which details why a connect request was denied? The files in /var/log/gdm are not very informative.

Networking :: Thin Clients On The Network All Have The LTSP Server IP While Surfing?
Dec 10, 2009My 32-bit Ubuntu 9.10 [Karmic Koala] LTSP server has two NICs, one with Dynamic IP set by a DSL modem and the other with static IP of 192.168.0.254. I also have 4 thin Clients that boot from this server without any problems and another computer with Ubuntu 9.04 running some PHP programs with dynamic IP given by the same DSL modem. When I send requests to these PHP programs from thin clients, they all give the LTSP server's dynamic IP as their IP so I cannot trace who has sent this request to response back.
I actually know this is logical. Because the requests are sent by a program that's actually running on the LTSP server rather than the thin client. But my question is How can I run a program on a thin client with it's own IP? I also should mention that the dhcp3-server service running on the LTSP server has no conflicts with the DSL dhcp on the network and I know that the 4 thin clients get the IPs ranging from 192.168.1.101 through 192.168.1.104 from the dhcp3-server service. Because I can ping them while they're on. but /sbin/ifconfig on them shows info about the LTSP server.
Ubuntu Networking :: Setting Up IPSec VPN Server On 8.10 LTS To Work With IPhone Clients?
Apr 3, 2010I've searched through google, and all I can find are instructions on how to set up a L2TP/IPSec VPN that works with macs and iPhones. I'm NOT trying to set up an L2TP/IPSec VPN. I'm trying to set up a pure-ipsec vpn.
The iPhone IPSec client is a built-in cisco client, I believe. I'm staying away from L2TP and PPTP because I need multicast packets to go through. *edit: wow, i just noticed that the title says "8.10 LTS". Oops! I obviously mean "8.04 LTS". Gah, the lack of sleep got to me.
Ubuntu Networking :: DNS - Clients Unable To Properly Resolve The Server's Ip Address
Oct 4, 2010I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
Ubuntu Networking :: Ltsp Server Subnet - Log Clients To The Parent Domain?
Mar 10, 2011I have an Edubuntu server with two nics joined to the primary windows domain and I can log on with domain credentials and everything is AOK. I used LikewiseOpen 6 to join the server to the primary domain. So, on my Edubuntu server eth1 is connected to the primary domain and has a static IP. eth2 also has a static IP and is the DHCP for the thin client subnet, connected to a switch. IP forwarding is enabled.
DOMAIN - eth1 - Edubuntu Server - eth2 (SUBNET) - switch - clients
So far, so good: I can log on the thin clients with one of the local accounts specified on the Edubuntu server and with that account I can surf the net and, if I supply domain credentials, browse the primary domain. Problem I have is:
I can't work out how to log on to the primary domain with a Active Directory account directly from a thin client. If I try DOMAINuser to log on, after giving the password, the password screen refreshes and 'domainuser@11.*.21.*'s password' appears under the blank password box. The IP in that message is the IP for the subnet and not the primary domain. I feel like I'm miss-understanding some basic simple step but I just can't figure it out.
Networking :: Setting Up A VPN For Windows Clients To Reach Debian Server Over The Public Internet
Jan 30, 2010I'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.

Networking :: Set A Route For Eth1 - DHCP Clients - To Reach Tun0 - Openvpn Server - CentOS
Sep 21, 2010I have openvpn tunnel setup between two CentOS servers. One of the CentOS servers also acts as a DHCP server for some client computers.
Server A= OpenVPN server
Server B= OpenVPN client (connects to Server A with OpenVPN)
The two CentOS servers can ping each other (172.16.0.0/24) via the tun0.
However, client computer connected to Server B (DHCP server) can't reach 172.16.0.1 (which is the OpenVPN server).
I think I am missing some routing in my "ip route show". Following is the full picture:
What command can I issue to get this fixed? something along ip route add?
There is no firewall service on both end. service iptables stop! I can't bridge eth1 and tun0 as DHCP server might mess up the other side. I can't do a push of "redirect-gateway def1" because then clients loose their IP as they send DHCP requests to Server A.
CentOS 5 Server :: TFTP-server Unable To Send Files To Clients Outside It Subnet?

But I have one server were I re-installed Debian Lenny - or tried to. At the stage were it wants to connect to a mirror it cannot due to network problems. I tried a new install leaving it behind a router. This solved the problem and it connected. Tried once more directly connected to a static IP and same problem happened - it got to the point with the mirror. Tried changing the settings after the installation through the router. This is what I get from ifconfig :

If I ping it from one of my other servers it shows as OK and can also ping my other servers from the server in question, but if I ping google.com it times out (fails). The IP 92.62.196.77 is in the range that I can use. Checked that with my ISP. Just to make sure I tried disconnecting one of the servers that I have working and changed the server in question settings and still it came out with the same problem.
