Has someone using opensource SPICE [URL] wit WIN7 Prof. desktop across the low 2 Mbps WAN with 50ms latency? BTW we're using VMware View 4.6 Desktop with WIN7 Prof. (PCoIP) and have a lot performance problems across the WAN.
View 4 RepliesSPICE has been getting there for a while now and seems to be a very capable mechanism for running remote desktops. (You see where I'm going?) Virtual desktops have a good chance of becoming all the rage if SPICE gets a low enough latency implementation. But what about applying that low latency implementation to running over a physical layer? Who says the host machine has to be a virtual box? (See where I'm going now?) Does anyone know if I can start using SPICE as an alternative to NX for example?

Is this possible using USB ports? Would I need a 2nd video card for the monitor?
View 1 Replies View RelatedInstalling spice is my first attempt at compiling anything from source and it has been an incredible headache so far. After going round and round for 3 hours chasing missing dependencies I'm finally stuck at a place where I don't know how to proceed. According to the instructions I'm following: "In case of an older kernel (version < 2.6.30)Get kernel sources using the following git repository:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.30.y.git
cd <spice_root>/vdesktop/kernel
./configure
ln -s <linux-2.6.30 source dir> linux-2.6
make sync
make "
Unfortunately my CentOS box (the one I'm working on) doesn't have internet capability, so I have to download everything on my windows box and burn it to cd. So I downloaded the 2.6.30 source from kernel.org, copied it to my CentOS box and unpacked it. I got as far as "make sync" in those instructions before I hit the next snag. When I tried to "make" it gave me an error "/lib/modules/2.6.18-194.el5/build no such file or directory"When I look for the referenced "build" file, it says link broken and when I follow the link to "/usr/src/kernels/2.6.18-194.el5-x86_64" which does in fact not exist.
So a quick google search reveals I need the source for my current kernel in addition to the 2.6.30 kernel source. The instructions here:
[URL] for the full kernel source look hugely complicated and involve rpms which is something I know nothing about. I tried to yum install kernel-devel hoping that would appease the unhappy make build, but I'm limited to installing things on the CentOS install DVD and yum tells me "error downloading packages" from the DVD repo, so I guess the source files are not the DVD? To top it all off, I only have 30 Mb of free space left on this drive anyhow, so I don't think there is room download the whole source anyway unless I put it on cd and mount it or link to it somehow in ways that make my tired brain hurt.
Spice server/client configuration. I used remote viewer on debian jessie to connect to a guest virtual machine on kvm and everything works fine. It used a spice server / client and qxl. After I upgraded to debian stretch, I suddenly face issues with black bars in the remote client window. Those black bars appear only on the left and right side of the remote viewer window. Also in full screen mode the black bars sadly appear. Maybe the scaling mode is somehow disabled or my screen resolution of the host was wrong calculated related to that i can change the guest screen resolution but the spice remote client keeps its window size with the black bars. I was trying the last couple of days to resolve this issue, unfortunately without success.
View 10 Replies View RelatedWe are running in to a issue where we don't seem to get our bridging to work as we expected. Meaning passing all traffic from Point A to Point B. As explained below:
[Code]...
This is the original connection. Now we are adding our Linux IP impairment box for IP tables in between Application Server A and Router X so the figure would look as below: Application Server A --> IP Impairment box --> Router X --> router Y --> Application Server B
The issue we are having is When a packets are sent from Server A to Server B they are going through for PING, TCP, UDP, but for BGP the connection is established at a TCP level (SYN, SYN-ACK, ACK), but the BGP OPEN packet does not get through and our BGP relation ship does not come up between Application Server A and B. Application Server A and B are a routers also but there are applications running on those router. BGP is underlying protocol used for Application Server A to be talking with Application Server B and getting routes for each other.
Even with the iptables empty (all rules default ACCEPT) we still can't seem to get these BGP OPEN's through. We see both sides of the application servers sending BGP OPEN's, but the Linux bridge never passes those packets to the other side of the bridge. Tracking the BGP packets, we see the packets at iptables raw PREROUTING and filter FORWARD tables but the packet doesn't get out the other interface.
The three lines in /etc/services for nfs (2049) has UDP, TCP and one I haven't seen before sctp. what is sctp and does iptables block it?

I am trying to backup my CentOS5.5 webserver to our local windows sbs 2003 server in the office. I have set up ssh and cwrsync on the windows server and have confirmed that the linux server can reach the windows server via the command: ssh RemoteUser{AT} It asks for a password and connects fine.

I get this error after entering the password: protocol version mismatch -- is your shell clean? PS I had to use {AT} instead of the proper character as the forum thought I was posting a URL

The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

Using CentOS 5.5. I have ssh setup to use a radius server for authentication. When I use filezilla to test sftp I can successfully authenticate and get directory listings, but every time I try to download or upload a file filezilla attempts to re-authenticate which fails because the radius server uses token auth with one time passwords, so the original password used to authenticate is no longer valid. However I can browse directories all I want and it never tries to re-authenticate.
1. is this re-auth just how sftp protocol was designed? like re-auth anytime a user tries a different action, like browse vs download vs upload?
2. or am I just missing something? (very likely, I'm not real experienced with linux)
I have Debian 8.4.0 with gnome gdm3 and NVIDIA GeForce 8400 GS. When I run some applications the following message appears:

Previously, I had lightgdm instead of gdm3 and I fixed this problem allowing indirect GLX protocol just setting xserver-command=X -core +iglx in /usr/ share/lightdm/lightdm.conf.d/50-xserver-command.conf...Now I can't allog GLX protocol. I have tried the following:
Set Option "AllowIndirectGLXProtocol" "On" in xorg.conf Set serverargs="+iglx" in /usr/bin/startx Set exec /usr/bin/X in /etc/X11/xinit/xserverrc
Despite all this, the error message persists and xorg.0.log indicates that indirect GLX is disabled (line 19.477):

I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol.
I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour :
In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame.
In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog.
I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.
I installed ubuntu server 10.04 32-bit and I installed XRDP so I can connect to it using RDP sessions. I was wondering if there is a better alternative to it. I have the following issues with it: 1. When I connect to the server locally using rdp it works just fine the first time. Then when I close the session I cannot connect to it again (it says connection timed out). Then if I uninstall then reinstall it will work again for another time then do the same thing. 2. I receive a protocol error when using Windows 7 or RDP version 6.1.7600 (Newest RDP version)

View 2 Replies View RelatedI'd like VOIP that works. VOIP is essential for my work, video would be very, very nice for keeping in touch with loved ones (keeping in touch with little nieces as they grow up, that kind of thing). It would be nice to get Skype working, but a more open alternative would be good too. Skype worked fine with Mandriva 2008.0, I couldn't get it working with acceptable sound quality in 2008. 1 in spite of following instructions. Now it seems broken in 2009.0 too, with no clear instructions on how to make it work - I just don't want to get into another vortex. Especially since, as I now discover, Skype does not support the open "SIP" VOIP protocol.
I gather that MSN & Yahoo both do support it, and Google Talk supports other protocols for text (not sure about voice) so I could connect through Ekiga, for example. I just set up Ekiga Softphone - don't know if it will work, but it's asked me to set up port forwarding without giving me the first clue of how to do it or which ports to forward. I'm also thinking about changing to Debian - I want a distro that lets me configure it at install, setting up the system to be very light and fast. (I'm not really a Linux Geek, but at least I figure Debian should be well documented, and stable and fast enough to make it worth the trouble.) Does that affect my choice of VOIP?
I developed a protocol "it's a modification of OLSR" for wireless networks, it was with JAVA and I try to simulate it on NS2, I used AgentJ, so in the TCL I did any thing like usual;
set val(chan) Channel/WirelessChannel ;# channel type
set val(prop)Propagation/TwoRayGround ;# radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
[code]....
and I didn't specified the protocol because I attached my nodes to the JAVA class responsible for the protocol, but when I run it generates errors, it claims the protocol to use, so I don't know how proceeding.
