View 14 RepliesI can't get past the "scp -p id_rsa.pub" step; ssh fails with "Could not resolve hostname" errors. Both machines are connected with a hub. I've also tried using the IP address in the place of hostnames with no avail. Both machines can ping eachother successfully.The server has the "openssh-server" package installed.

I am running three ubuntu computers on my local network:my desktop which runs ethernet, and two laptops which run wireless on the same network, and all from the same router. For purpose of this thread, I am concentrating on this one issue with pulse(assuming its pulse doing this). When I have two computers running at the same time, or even all three, I can hear bursts of sound coming from the other computer, not all the time, but consistently. I don't know what is causing this. I've searched hi and low in all ubuntu pulse audio forums and those mentioning pulseaudio and I have not seen this issue posted anywhere. Most threads deal with issues of not being able to get pulse to recognise audio from one computer to the other...mine is just the opposite...I'M TRYING TO STOP THIS FROM HAPPENING!......

How do I make a local mail server that itself is a client to a WAN mail server.I want the local mail server to query new mail every 30 minutes from the WAN server.
View 6 Replies View RelatedI want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.

View 5 Replies View RelatedI'm trying hard to run an openvpn server on a openvz VPS, the problem is packets sent from openvpn server process, doesnt reach the client, so connection is never stablished (I run tcpdump on server and wireshark on client to carefully investigate whats wrong), the first guess is that a kind of firewall is blocking traffic (I tried connecting to server through different ISP's but it's possible the national network provider applied some filtering but it cant be on IP,src port or dst port as I'd tried different configuration.
what about deep packet inspection technics, is it possible to block my traffic?) but at exactly the same time I can transmit UDP packets using netcat from server to the guest. there is no firewall enabled in between, I had tried, tcp and udp, tried both open vpn and openvpnAS and tried any thing one can imagine! the VPN is configured as a routed (TUN) type on debian

We're setting up an OpenVPN access server, a quite straight-forward and very customizable system.

The requested method is not implemented by this server. Although we have added on the cisco router a port forwarding for port number 9943. It is working when we access the website : port with the local IP address [URL]...

I am connecting servers using NFS4 the shared directories are on servers running Debian 4 while the one who read from them is Debian 5.0.3. The problem is one of these shared servers suddenly stop responding and you cannot list it from Debian 5 server, also df hang, and the web application that is using it does not respond to requests that use this shared directory since it is blocked. Then the load on the server start to increase until the server cannot respond (over 90). I have found many entries in the syslog that refer to this like:
ma25555 kernel: [1200285.732919] nfs: server 10.xxx.xxx.xxx not responding, still trying

I have tried the connection between the 2 servers using ping for one day and all are OK (zero lost)
There are 3 other servers that are running Debian 4 and are working fine.
I've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

The issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.

I am now trying to setup a VSFTP server where local users can upload files to there home directory so that Apache can serve web pages straight from the directories of system user home/accounts giving users the ability to run their own web sites which are hosted off the main server [tutorial here: [url]
So far i have been able to serve/display index.html files from the users home directory [url] but so far i cant upload files to any user home directory, every time i try to upload a file with filezilla i get this error message: 553 Could not create file. Critical file transfer error
I have searched online for similar problems like mine and so far i've tried alot of the solution but none seem to work.

Also the root directory where the web pages are served from is called public_html here are the permissions
Here is my vsftp.conf file can someone check it to see if i made any errors in there:

View 6 Replies View RelatedFolks, I have an old notebook (IBM T23) running as my print server on the home network. Recently my wife needed to fax some documents. No problem, said I, I will just set up a fax server. That was months ago and I have achieved nothing more than dig a deep pit. Sigh.
Could some kind person give me step by step instructions for this?
Setup: LAN including IBM T23 with an external modem (it has an internal winmodem, but I expect using that to be just too hard) and running FC10. This machine currently has the only printer, accessible from all machines on the LAN.
Wish list: Be able to fax from any machine on the network, via the T23->modem. Preferably, to see the fax device as a printer on client machines, so it is a simple matter for my wife to 'print' to the fax. Machines on the LAN are FC10 (wife) and FC11 (me). Ability to receive faxen is not necessary, but if it is feasible I MIGHT try to set up for it too. The phone line is our normal house line, so I don't want the fax to pick up any incoming call unless I instruct it to.
Current status: Hylafax installed on the T23. So far cannot make it recognise the external or internal modems. Have not figured out how to make it appear as a printer on the T23 or over the LAN. The problem is me, but at my advanced age I am not too proud to admit my failing grey matter and ask for help.
Kind regards, Doug.
In my computer networking class I have the option of doing a project where I set up a dns server for our classroom network. The problem is that this network is totally separate from the school network and we aren't allowed to connect it to the internet. I want all the machines to ping each other by name instead of ip using dns instead of host files on all 20 computers. I read on a site somewhere that you cannot do this because the dns queries will always go to the root servers. Is this correct? Is there some way I can do this using dns? The machine in question is using Ubuntu 9.04.
