So what I'm trying to do is write a USB stack for a uC, but beyond the 10 ms reset signals from the host I'm kind of lost. What happens after that? If someone could point me somewhere that explains it step by step in detail, instead of jumping around

Is there any guide available explaining how to setup Chat and Broadcast?It is not very important (I dont use it much), but as ubuntu is now "Social from start" and very user friendly it should be very easy.However I have not been able to set it up no matter what i have done.
View 3 Replies View RelatedI 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.
There is a protocol in use - for example when I use Firefox to do a query through Google - as I type into the search field the browser sends my characters - one at a time - to the server. As I recall, at one time I found the specification but I'm pulling a blank. As I recall it does a POST of each character as I enter it, and the server responds before I have entered a <CR>. I want to write a client side program that uses that protocol and need to see the spec.

I want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.

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:
Code: Select allname of display: :0

Minor opcode of failed request: 24 (X_GLXCreateNewContext)
Value in failed request: 0x0
Serial number of failed request: 33
Current serial number in output stream: 34
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):

We 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.
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?
