Is there a vpn client out there that:
1) doesn't require a group password
2) doesn't require a cert
3) can work with cisco any connect
the vpn server admin is being pretty obstinate and uncommunicative
is there such a program?
[As RHEL licensing has changed over time, please don't attempt to answer these questions unless either you are confident of the answer, or you have recent experience with these items.]
We are virtualizing our data center. We have a total of 23 HP blade units (2-sockets each) that will have hundreds of potential RHEL 6 virtual machines running on them within VMWare. All of these VMs (Set 'X') will need to have rhn_register run on them so that patches and updates can be routinely applied. A subset of X - call it set 'A' - of these VMs will require 12x5 support (Standard Support) from Redhat. Another subset of X - call it set B - which is mutually exclusive from set A, will require 24x7 support. For any given server, we can not yet identify which will be in Set A, Set B, or just in X alone.
If we decided we had no need for phone or web support, but wanted to be able to use RHN for patches, would purchasing one Self-Support entitlement for each VM suffice? We are probably looking at the Unlimited-number-of-guest-OS subscriptions. Is there any way to purchase Premium (24x7) support for some VMs and Standard (12x5) for others? Does the count have to be decided ahead of time, or can we decide on the fly?
In other words, can we wait until a VM crashes over the weekend to call Redhat and say "We need this VM on premium support" ? The motivation for this inquiry is that we don't have the budget to put 23 blade units' worth of VMs under premium, or even standard support. I'm curious how Redhat manages this, since subscriptions are done per physical server, not per VM. (When you're dealing with the unlimited-number-of-VM pricing.)
I successfully edited the .bashrc file to get ruby version manager (rvm) working. Now I would like to turn that setting into an alias so that if i type the word 'ruby' into the terminal it not only goes to the rvm settup but also defaults to my webdev folder which is in my user home directory and also exicutes a command that will open up gedit ready to be used as the text editor for editing the .rb files. Can this be done i would settle for some added code for the 'if then' statement: so far it looks like this:
[Code]...
I don't want to mess with the default setup on this system too much and think things could get out of hand if i am not careful. So am cautious about doing anything at this stage. I wonder if it is possibel thought to setup that whole 'if then' statement as an 'alias'. I read a few referances to alias and looked in the manual like any good newby should but am needing your help please. getting out of the MSwindows mind set and into the linux logic is not so easy but is a great experience
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface
auto lo
iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
I have the following problem:I have to networks in remote places.I have an opnvpn client in one network that connects to the the router (openvpn server).My question is,can i connect the network where the openvpn client is,throught the computer with the client to the other network.If yes,how? (please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface

I would like to be able to mount a share served by my mac os X machine(10.6.1). I have read the Ubuntu community doc on Ubuntu samba clients.It didn't say what to do when using dynamic LAN I.Ps.I understand the way to go is to use avahi on the client side(Ubuntu) and Bonjour on the server side(mac os 10.6.1).I can't find anything about how this is done.What do i need to do to set up the client side(Ubuntu) to use avahi with SAMBA?.Because in the Ubuntu community doc it just referenced /etc/hosts, which is for static I.Ps.So i'm assuming that SAMBA on Ubuntu doesn't use avahi by default.All i need to know is how to set up the client side of SAMBA on Ubuntu when i'm using dynamic LAN I.Ps.

I am trying to connect to an existing VPN server that I have been using for years now. I am moving my develpment environment over to a Ubuntu box and I must have openvpn working in order to access SVN. It has been a few years since I have been setting up linux boxes. And networking is a soft spot for me. But
The server has been running without problem for a LONG time. A windows computer I have been using connects to it fine and I can access the network on this machine. I am setting up a new computer, but when trying to connect openvpn starts the initialization sequence completes but I cannot ping the network I am trying to connect to.
I use a second VPN connection to connect to an alternative network and it works fine. The difference between these two is that the working vpn connection is a routed IP tunnel and the one that is not working is a bridged connection.
The VPN that is working on this box brings up tun0 while the bridged connection connects but does not bring up a network tun device. The server logs look normal, it just looks like the client is not setting itself up to use the network once connected. (The key/cert pair work find when on a windows box) Just not on this new ubuntu build.
My current client config
Quote:
cert eric@home.crt
key eric@home.key
client
dev tap
[Code]....
The server is using tap, as well as the working windows client uses "dev tap"
It has been a long time since I have been maintaining linux boxes but its coming back slowly.
Do I have to bring a device up manually ?
I'm using a Kubuntu 10.10 Client Machine which mounts NFS shares form a Kubuntu 10.04 Server.The server seems to work smoothly but the client causes huge problems since I upgraded to 10.10 (before I used 8.04 which worked withouth problems).My problems are, that in various situations the use of the NFS shares causes the Client to freeze completely!Examples:Unzipping a big file from the NFS server to the NFS server via the client -> always immediate freeze (after some seconds)Transfering big files from one NFS folder to another -> mostly immediate freeze (after some seconds)Viewing a movie which is on the NFS server -> sometimes freeze after variably amounts of timeLetting the Strigi-Indexer index files on the NFS shares -> mostly freeze after a short whileIt seems that everything that puts some load (high data transfer) on NFS immediatly locks up the whole client.

I briefly was able to share a folder in my Windows machine, and access it through my Ubuntu machine, after connecting both laptops with a cross-over cable. However, I can't even ping the Windows machine from my Ubuntu machine anymore, after trying to configure the IP addresses. I think I screwed it up.
Also, although this is not an Ubuntu issue, I have a weird Windows problem, where I can't access the Internet when both wireless and wired ethernet controllers are active at the same time. It would be a bonus if you could solve this problem too for me. I was surfing online for a solution to this problem for quite some time, but I was unable to comprehensively understand and implement what I browsed through. Also, some of the guides, like for example, that on configuring Samba, seem to be outdated, as the terminal tells me something like the package (that was required to be installed by the guides through sudo apt-get install) has been superceded. Hence I post here for clear, concise and easy-to-understand help from you gurus. It would be great if I could achieve the end result of being able to access the internet on my Ubuntu machine (through the Windows one).
I have a number of Ubuntu machines running. Our NAS is FreeNAS. I am typing this on an Ubuntu 10.04 desktop that is successfully connects to an NFS share on the FreeNAS box every day. In addition, we have 3 10.04 server machines that also stay connected to the share successfully, Yesterday, I installed a new 10.04 server machine using IP 192.168.0.11. Everything works except connecting to the NFS share. It always returns with: mount.nfs: mount to NFS server '192.168.0.13:/mnt/amrd0s2/public-NFS' failed: timed out, giving up
Here's what I have checked: I can ping 192.168.0.13 (obviously) The NFS export mask is set to 192.168.0.0/16. The other machines are all on the same subnet as this problem machine (192.168.0.*) nfs-common, nfs-client, and portmap are all installed and running correctly. portmap is running correctly showmount -e 192.168.0.13 give the proper response:
Export list for 192.168.0.13: /mnt/amrd0s2/public-NFS/ 192.168.0.0 iptables isn't even installed (these machines are segregated in a private network behind a hardware fire all) There is nothing related to NFS is any of the syslogs. dmesg has one entry: [6.025966] FS-Cache: Netfs 'nfs' registered for caching which is insignificant. how to at least debug the nfs-client short of downloading the source and actually stepping through the code.

I am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.

View 7 Replies View RelatedI want to connect two computers using ssh. One is at work, behind a firewall (which I have no access on it), and the other is mine, at home. I want to connect, from home, the one at work at night.
Obviously, the computer at work should be the server, and mine, the client. The point is that the firewall does not allow it, maybe blocking any SYN bit coming from outside of work.
Since I can establish communication when the client is at work and the server is at home, I can make the computer at work try connection periodically, and when I want, take control of the client. Do you know any way of doing that with ssh?
I'm having problems with squid, and i don't know how to solve them because I'm new to linux. a. Why squid in my computer often does not work? The process has already started (using the command sudo squid start), but the Internet on client computers can not connect. This can be be resolved if the proxy server computer is restarted. Anybody know why is this happen?
b. How do I set the client bandwidth limitation using squid? I want the client computers can only use maximum 60-70 KB / s. Do I need another additional software package?
I set up an ssh server and configured port forwarding on my router so that I can access the ssh server from the internet. This is working fine, also from within the LAN.
Additionally this machine should be connected to an VPN Server on the internet. Again, this is working. I get connected, the tun interface is coming up, etc.
The moment the VPN Connection is established I can not connect to the SSH Server anymore from the internet, LAN ist still working fine. I guess it has something to do with the route that is set by the VPN Connection?!
So my question is, what do I have to do to reach the ssh server from the internet while the ssh server is connected to an VPN Server itself.
ifconfig without VPN

I have a mate who runs the IT in his office. He has recently set up and secured the network but now has an issue logging in to the network from home. Here is the message I got from him regarding the set up and what he is having specific issues with.
I was really pleased with the results on my Pen Test; the office itself is a pure MS environment but the testers all use Ubuntu 9.10 to hack with. The main tools of choice are Nessus and Ophcrack with a bit of NMap. It's pretty scary what you can do with just these tools. I had a Wireshark trace running all the time and it's fascinating to watch how these guys crack open a system. The only really major change I've had to implement on my network is to force the use of SSL as a transport layer for our remote desktop sessions. This has forced me to start using MS RDP Client 5.2 because it can use certificates on the session. The problem I've got now is that the Terminal Client in Ubuntu can't do this so I can't remote in from home on my Ubuntu laptop.
I have an Ubuntu server that is currently running Ubuntu 8.10. I was thinking of making it a VPN server for my iPhone and also for my laptop whenever I'm outside and need to access internet over insecure wireless networks. Now that part should be easy I found several guides on how to configure OpenVPN server, as well as enabling clients on iPhone, and OSX.
However, the things is that my server is currently a OpenVPN client also, I have a paid tunnel set up to bypass my ISP blocking incoming traffic on various ports. Is it possible to keep this setting but still enabling a VPN server? Essentially causing traffic from my external device to go in through my tunnel to the VPN server, and then out through the external VPN provider.
