View 3 RepliesMore for my own posterity than anything else, I thought I'd document here the way to get to eDesktop through linux (debian, ubuntu) at the University of West Florida (UWF), since they appear to only support Windows through their documentation on the University web site, and the link through Argus (the secure web site) doesn't work in Linux. This is sometimes needed to use the University resources (libraries and computer programs) from remote locations, and otherwise a google search is fruitless. I had to have a guy in the computer science department show me how to do it.This may apply for other Universities with similar setups.

I'm running Lucid on a laptop client and a desktop server. The server has windows partitions that I'd like to connect to from the client using nfs over a wireless link on my home network. Is this possible? (I'm currently using samba but find it slow and stalls shutdowns on the client.)I've successfully connected to ubuntu partitions on the server via nfs, but most of the data is on the windows partitions, and must remain there.
View 4 Replies View RelatedI'm trying to connect to a Microsoft ISA PPTP server from my Linux box. The box I'm connecting from is itself a router. I have no problem connecting a Windows XP machine to the VPN via this machine. This is fine, but I would rather connect via the Linux machine, giving me far more advanced routing options (i.e. no to send every packet from the XP box completely unnecessarily via the PPTP tunnel). The Linux router is running Debian Lenny.
I've checked iptables. There were initially some issues. I've fixed those.
Invoking pppd from the console, I can see that authentication succeeds, but then some negotiation goes wrong and the server terminates the connection. Here's the output from pppd, with the more sensitive stuff removed:

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

View 3 Replies View Relateduntil 2 weeks ago I had o.S11.3 on both my Siemens and Asus laptops. I have installed NX No Machine. ( I know it's not open source,I am using the free version). With commandline ( root) /usr/NX/bin/nxclient I was able to connect to the other machines. I got Qt: Locales not supported on X server, the NX menu popped up and I was able to connect by inserting resp codes. After fresh install of o.S.11.4 on the ASUS the commandline (root) answers:
xlib: connection to":0.0" refused by server
xlib: No protocol specified
nxclient: cannot connect to X server:0.0
The ASUS can still be reached from the other machines (one with o.S.11.3,the third one with o.S.11.2 ) SSH ( Lan)connections are all working forth and back between the machines, even to and from Win XP, however only from Win 7 on the ASUS, but that's a Win7problem. Comparing the installed xorg-x11- server-extra : on o.S. 11.3 Additional X servers ( Xmdx,Xephir,Xnest,Xvfb ) ,on o.S.11.4 the Xvfb is missing, might that be the reason?

So a while back I was able to mount a directory from my OpenSuse server as a NFS on an Esxi server. After restarting the Esxi server, the NFS became inactive and I was unable to remount it. The error given was that the Esxi client was unable to connect to the Suse server. I was looking into the showmount -a command on the Suse server and it showed the mount point on the Esxi server. Could this be causing the Suse server to reject new attempts to mount the directory? What else can I try to fix this problem? Also I should note that both servers can ping each other.

I am trying (desperately) to setup freeNX so that I can access my Mandriva box from my Macbook over my network. I have great need to be able to do this. Here's the necessary info for you: Mandriva PC: running Mandriva 2010.0 with freeNX installed from the Mandriva repos Macbook: running OS 10.4 with the Nomachine NX Client installed Now, I have followed the setup from the Mandriva wiki as well as the freenx wiki to no avail. I simply cannot connect the Macbook's NX client to the server. I get an authentication failed message. However, I can ssh from the Macbook to the server just fine (that's how I'm getting most of this work done).

I was wondering if there was a way to connect over ssh "backwards". For example, lets say there's a client connected to example.com via ssh from behind a router. Well you wouldn't be able to ssh to that client unless the proper ports were forwarded on the router right? So I'm wondering if there would be a way to connect to example.com through ssh then from there connect to the client using the already existing ssh connection.

I'm trying to set up a VPN connection between our CentOS 5.3 server at work and my bosses XP computer at home. At this point, we are kinda locked into Quickbooks. I'm testing the connection from my XP boot at home to see if it works. I can log into our servicemanuals easily enough from XP at home however, the windows takes forever to update. I have the Samba server only listening on port 445 because is seems to work more efficiently at work. I connect to the Samba shares via linux from home and everything works well but, when I try to do anything with the shares from Windows client at home, it's very slow!
I'm thinking that it must have something either to do with the Windows OpenVPN client or the client.conf file. Is there anything I should look at in the .conf file for answers?

I want to use FTP client (for example ncftp) to connect in active mode. I have firewall (iptables) on my laptop and most of time I am behind rooter. With outgoing packets and with passive mode all is working fine.But some sites accept only active mode.I could open some port range in firewall and in rooter for active data packets, but I don't know how to solve security issues.So how should I correctly manage active ftp connection?
How can I set data port range when opening active connection with ncftp (or maybe another ftp client)?How can I limit that incoming connections to that ports range is accepted only by ncftp or else dropped?
Linux VPN client exists which will connect to a Sonicwall firewall?
