Ubuntu Networking :: Setting Up SSH Server (Hamachi Based VPN)
Jan 8, 2011
I recently started to set up a SSH server, I was able to set up a Hamachi based VPN and was able to connect to it on all levels, for about 5 min, after that the server goes into idle mode and is no longer able to connect to that computer via LAN or Hamachi. Not till after I shake the mouse can I connect back in via LAN, and I have to log out and back in of Hamachi to get that to work. Is there a way to stop the Internet shutdown on that computer when it goes into idle mode? SSH servers are more or less useless if it doesn't let me tunnel in when I need to. This is for Ubuntu Server.

I've tried to install Hamachi on my Ubuntu 10.04 but it was unsuccessful. I followed the steps below based on a tutorial i found on the web: 1. Made the fake module "tun", necessary for running VPN apps, which in Ubuntu 10.04 is already compiled in the kernel.Reading several forums on the web they say it was a "work around" for getting VPN apps to work...
A - mkdir faketun
B - cd faketun
C - echo -e "#include <linux/module.h>
[code]....

run a Hamachi client in a Windows virtualbox and be able to set it up (using network bridging, maybe?) like Hamachi was running in the host itself.
I'm most definitely not a networking expert, but I thought it would be worth a try to see if anyone had any ideas. Hamachi for linux is outdated and unstable.
Also, if this isn't possible and anyone has another cross-platform zero-config VPN solution as stable as Hamachi

I've just loaded the new Hamachi2 Linux beta with Haguichi for a GUI. Everything installed & connects OK, but the connection at the hub is dropping & reconnecting every minute or so. I tried adding a line to the sshd_config file to keep it alaive but it didn't make a difference.

I am not well versed in networks, I want to understand whether broadcasting is possible through a TCP based Server? If yes, then what are the complications? I searched Google and found this: [URL] It said
Quote:
The types of broadcasting uses on TCP/IP that I know about are:
1. ARP on IP
2. DHCP on IP
3. Routing table updates.

I've been trying to set up a music server and running into some difficulty.
I want to be able to stream music and video to my network and over the internet.
From what I've read so far ampache is what I would like to use but I've yet to find a user friendly guide on how to set it up. I've never set up a server before so all of the guides and documentation have just confused the heck out of me.

I'm setting up a loopback server for work related testing. I have a small program that needs to be executed through telnet from about 200 IP's on the same network. On the server, I have to set a static ip, enable telnet login, and place my 2 program files in the appropriate folders so it will run. I have been on this for 2-3 days and haven't got far.
My /etc/Network/interfaces file is this...
Auto lo
iface lo inet loopback
The rest of terminal is filled up with these, and it states that the file only has 32 characters. I don't know if this is a privilege issue or not. I've read several threads on telnet, and lots of arguments about ssh, but I can't run ssh, so I need to enable telnet. There is not a security issue. I run a private network where the only valuable resource would probably be the text file with my IP address on it. Its also accessed by people that have very limited networking knowledge and no linux knowledge...
So,
Set static IP
Setup telnet server...
Any takers?

I'm trying to set up an old computer that was donated to my by an aunt to hold my external hard drives and use it as a file server so i can use them from anywhere within my house. However I can not seem to get the samba server to broadcast/be seen by my ubuntu installation, nor my windows installation.
I've read the manual, to an extent, but I feel as if I am missing something. All I want is to have it to where I can just type in \server and bring up my files to access without having to worry about passwords.
Here is the config file:
Code:
[global]
workgroup = WORKGROUP
netbios name = GrenadingBadger
security = share
[Code]....

I do not know much at all when it comes to setting up hardware--servers, switches, etc.
I have a 1701HG 2Wire wireless router that I use for my home network. I have an old pentium 3 tower that is just laying around, and I want to be able to host my projects on it for testing. Basically, I just want to be able to do everything on my laptop and then upload it to the server for testing.
I have set up an Ubuntu LAMP server on the desktop and am able to do everything I want via SFTP; however, I want to be able to type in "projectx.local" in a browser on my laptop to go to one test site, "projectz.local" to go to another, etc.
Is this possible, since I do not have the server set up as my gateway? It is merely connected to the router like everything else.

post the "perfect" tutorial for setting up a router and firewall for Ubuntu 10.10 Server 64-bit? I'm kind of a n00b when it comes to Linux, so I get really confused with some things, I have seen things on the ubuntu wiki about this... but it really confuses me =
I'm trying to setup my ubuntu sys as a router and firewall... Internet -> Ubuntu (Router) -> Switch (no DHCP on it) -> Computers I've already setup bind and dhcp3 and got those working perfectly... I've also setup Squid3 and Dansguardian for content filtering (blocking ads and such) and got them working too... I want to set it all up to be transparent, and allow the system itself to function as a powerful firewall router, giving absolutely NO issues to client computers connected, and no speed reduction at all.... I want to setup the firewall to allow all outgoing connections, but block everything incoming (stealth the network)... Forcing all http/s traffic to pass through dansguardian, then to squid...
But am very confused on how to pull this off... The system is running Ubuntu 10.10 Server 64-bit, with 4 GB of RAM, 320 GB SSD, and two 1Gb NIC cards... Sorry if I'm not very clear, I do speak english perfectly, but just kinda new to the "Linux world", I was using SONICWALL but that's getting a little too costly to my network and wanna do a free alternative... Something completely CUSTOM, not using some network security distro.

I used windows OS and installed Ubuntu 10.04 (amd64) in separate partition and works well but had a problem in internet connectivity. Likely reason may be the proxy setting that we used in college (currently). I used this commands to set up the IP address and gateway.
ifconfig -a | grep eth
"eth0"
sudo ifconfig eth0 192.168.5.209 netmask 255.255.255.0
[code]....
Then I manually set the proxy setting of HTTP which is given as proxy server 192.168.5.2 and port as 8000, further more there is a wins setting which is 192.168.1.178, really don't know where to put this number.

Looking to force eth0 & eth1 to 100MB Full Duplex/Auto Negotiation off but am having trouble.
When I run: "ethtool -s eth1 speed 100 duplex full autoneg off" manually, it works fine. However when I add it to the intefaces file it does not after several different configuration attempts:
/etc/network/interfaces:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
#auto eth1
#iface eth1 inet dhcp
[Code].....
it seems my current configuration wont allow both eth0 and eth1 to be active at the same time. I would like them to be active-active if possible (if one goes down the other will service all traffice and vise versa).

I'm going to be going off to college in the fall and the internet probably won't be blazing fast like it is at home, so I was wanting to set my desktop up so that it would act as a local cache of the parts of the internet i frequent the most, but I can't find anything like that. All the tutorials I've found are either for sharing the load on a server or for setting up a separate machine as the squid.

To be short and to the point, I want to setup a service with my clients and allow them to back up to one of my servers. What I would like to do is allow client connections via WinScp to a ssh server that has home directories for each user to backup data. If users want their data I would like them to be able to connect to my apache web server (same as ssh) and download from anywhere.
Is there a way for apache to link web directories on the server to the actual /home/user account and use the same login information/authentication?? Does this make sense? I really appreciate the help. I am not a developer or else I would simply develop a user friendly front end for to an ssh server. Since that is the case I think this is the best solution for me, as well as the easiest for the client.

Ive spent the last couple of days looking for a way to set this up and cant find the solution anywhere. Right from what iv read so far i understand i have to set the card to master mode but when i try
Code:
sudo iwconfig wlan0 mode master
i get the error
Code:
Error for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Invalid argument.I read somewhere that the madwifi driver is up to the task but im still quite new to linux and not really sure how to change the drivers. this is what iv done so far
Code:
wget http://snapshots.madwifi-project.org/madwifi-trunk-current.tar.gz
tar xvxf madwifi-trunk-current.tar.gz
cd madwifi-trunk-r4108-20100115/

I am using VSFTPD as my FTP daemon. I want it to be set up so that my user (cj) will have a default directory of / when I log on to the FTP server and I want the secondary account (guest) to have it's home directory as the default location without any access to the root of the drive.
I need my account to have the default as / because the FTP client that I use in Windows won't go up to the parent directory of the default. Therefore, I cannot access the rest of my drive.
When I set "local_root" to "/" , it brings both users to the / directory when they sign in, even though the guest account is set to open the home directory with the "chroot_list_enable". It seems like the local_root option overrides the chroot_list_enable option.
Is there any way to set the default directory for each local user separately?
Also, Let me know if this is impossible with this FTP daemon

I'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.

I've been having issues setting up the wireless interface on my Ubuntu server (command-line only, no GUI) and I can't seem to get it working. It seems as though the card is recognized, the drivers are installed and the interface is up, but it fails to connect. I have no idea where I'm going wrong. I have WPA and a MAC filtering setup on my wireless router. An exception has been made for this PC's MAC address and I've manually entered the connection details into /etc/network/interfaces.

I'm setting up a VPN with openVPN on a debian lenny server. I successfully installed it in the server, then created the certificates and both client (winXP) and server config files. For the client I use openVPN gui. I tested the tunnel and everything went just fine. I even can ping the openVPN server from the XP client.But thats all. I can't ping any machine behind the openvpn server.Some facts that you may find useful to help me with this issue are:
- The openVPN server is not the default gateway of the LAN. The dg is a pfsense server
- I dont have iptables enabled (policy of all chains are ACCEPT).
- I have configured ip forwarding (echo "1" >/proc/sys/net/ipv4/ip_forward)
[code]....
I have checked and all seems to be OK. I think that the problem is connected with routing the traffic from the vpn to my LAN but I don't know how to do that (besides the push route line in the server.conf).

I would like to set a double range of IP address with my DHCP3-server. Now, I have eth0 (which is my only network card) with this IP address : 172.16.93.1 and I have created a second interface eth0:1 with this address: 192.168.3.1. The goal is to give an IP address 172.16.93.X to phones (with option 66) and the IP address 192.168.3.X to the computers.
This is my DHCPD.conf :
ddns-update-style none;
option domain-name "mycompany.com";
option domain-name-servers 172.16.93.1;
default-lease-time 3600;
max-lease-time 2347200;
authoritative;
log-facility local7;
option ip-forwarding off;
default-lease-time 20;
max-lease-time 20; .....
Right now my DHCP server work fine, (I means, no error at the startup ) but the server give always the same kind of IP address, whatever if it's a phone or a computer. I notice something "wired", if I put the :
subnet 192.168.3.0 netmask 255.255.255.0 {
range 192.168.3.100 192.168.3.199;
option routers 192.168.3.254; }
(Which is first in the dhcpd.conf) after the "subnet 172.16.93.0 netmask 255.255.255.0", the server will give IP address 172.16.93.X at all the clients. Is it possible to give more than one IP range with one network card at the same time? And how set the option 66 to only give IP address (172.16.93.X) to the phones?
