General :: Running Tcl For Mobile Ipv6 / Creating Nodes And Setting Their Positions In Tcl?
Dec 1, 2010
i have installed ns2.33 and added mobiwan , i tried to run tcl script after modifyng simple tcl which i have got along mobiwan patch, but the problem is after creating some nodes and setting their positions in the tcl, according to my topology, i tried to run , but the command i have included in tcl , which sets the positions for mobile nodes, has no effect , which means that the positions of the mobile nodes is already fixed , trough tcl i am not able to change , and also each time when i run nam , different positions mobile nodes taking, and also the mobile node is not moving , even if i have given mobility to it, at different time , i have given different destinations.this is part of tcl in which i have set positions mobile node.
Code:
set cn_ [create-router 0.0.0]
set router_ [create-router 1.0.0]
set bs1_ [create-base-station 1.1.0 1.0.0 200 200 0]
set bs2_ [create-base-station 1.2.0 1.1.0 200 600 0]
set bs3_ [create-base-station 1.3.0 1.2.0 600 200 0]
code....
i have installed ns 2.33 and added the patch mobiwan for supprting mobile ipv6. i ran some tcl scripts , and below is the trace file generated. calculate the handoff latency, and if someone has awk or perl script to do so, tcl file [URL] out.tr [URL]
Are there any prerequisites which much be met in order for udev to create /dev/usb/hiddev* nodes?
I have two Slack 13.0 systems, each connected to a APC UPS via USB, one of which creates a hiddev0 node and the other doesn't. apcupsd can't find the UPS unless this node is present.
The "working" system has been stable in its current configuration for so long that I honestly can't remember if I had to tweak anything in this regard. I've verified that it doesn't use any local udev rules to create this node, and to the best of my knowledge there are no external scripts or processes which would create it either.
The non-working system has a similar configuration - no local rules and/or scripts which touch usb devices or nodes.
I'm putting a server together and have run into a boot up problem. (I thought about putting this in the server forum, but it might be a more generic problem that others have seen and know how to rectify.) The install seems to have gone just fine. I have the /boot partition on an internal IDE drive. The rest of that drive and another are mirrored in a Raid0 configuration (using the Linux software to do that) for data storage. The swap partition is a part of the Raid5 SCSI array that also has the / (root) partition on it.
After installation it would not finish the booting process. I suspected that GRUB didn't like all the Raid arrays and such, but it seems to be fine. I can say that because the machine will boot into rescue mode with the GUI splash screen and I have access to the whole directory tree. I have already searched on-line and following prudent advice, ran the yum update while in the chroot /mnt/sysimage mode. That only took overnight to download and most of this morning to complete. Still no dice. Used vim to delete the rhgb quiet commands in the grub.conf file so I could see where the kernel seems to be hanging.
So right after the "Creating initial device nodes" is a line about my generic PS2 wheel mouse. So I tried a USB mouse. Got more output so tried swapping out to a USB keyboard. Got a little further with more information about input devices, but still stops. Also, I tried a PCI video card just to make sure the onboard video wasn't the problem - no change. So, if someone in the Fedora community knows what loads up or is configured right after the mouse and keyboard, I might be able to figure out what's causing the computer to hang during the boot process.
Early in the boot process, system generates message "Creating nodes with udev." After a pause, CPU timeout dumps are listed on the display. Likely it is related to wthe display driver (Intel 845G) as the system can be brought up in failsafe mode. /etc/X11.conf is intact. The system was apparently successfully upgraded online from 11.3 using the zypper method. This issue has appeared a day following the upgrade, after restarting the 11.4 system.
setting up NAT and firewalling for both IPv4 and IPv6. The machine is headless, so everything must be configured via CLI. I've done all IPv4 firewall configuration writing iptables rules in a bash script so far
I decided to try and get my network ready for IPv6. All of my hosts are set up to do stateful autoconfig, I have radvd installed and working, and I can ping6 ipv6.google.com from my Ubuntu server. However, when one of the clients on the inside tries to ping6, no packets return and I get this message in the router's syslog:
Code:
Feb 8 17:55:17 foo kernel: [ 1344.824474] Dead loop on virtual device tun6to4, fix it urgently!
Since I got the liquorix kernel installed on my machine I got an error of setting kernel variable error. net.ipv6.bindv6only at boot time, since it wasnt a big deal I never looked further into it, but now that I had some spare time and I didnt want to see any errors on my machine I found a solution for it, with a little googling all we need to do is read the /usr/share/doc/procps/README.Debian and bingo no more error i hope this help anyone else with the same problem. I did the 3rd suggestion on that file to load the module in /etc/modules cheers.
On my Lenovo T410 (openSUSE 11.4 KDE - 64bit) I have mobile broadband. Gobi-loader is installed and working properly. However when I try to setup mobile broadband connection the KDE Control Module crashes. Tried many times also after reboots, though KDE Control Module keeps crashing.
Problems with setting up mobile broadband in KDE4? Than use this instruction: openSUSE starter: Step 2. Need mobile broadband? Use the GNOME applet to make the GNOME nm-applet work under KDE. With this nm-applet I have set up mobile broadband within couple of seconds.
PC1 and PC2 are linux pc's with linux 2.4 (or) 2.6 kernel installed on it.Observations are done on both 2.4 kernel and 2.6 kernel Problem explination:
1)PC1 "ifconfig eth1 down" on linux shell. 2)Check the "ifconfig eth1" on PC2 3) The running flags are unset first(disappear)and set(Re-appear) on the eth1 interface on PC2.
4) unset and set toggling happens with in short period of time about 1 or 2 secs.
This is clearly observed in linux 2.4 kernel with some time delay for the toggling, but 2.6 kernel this will happen every quickly..
I used to play with gw6c ( a client for tunnel broker ) It works well with fedora9 , fedora 10, but not with leonidas. my rpm is gw6c-6.0-0.4.beta4.fc9.i386.rpm ( a little old!) when I tried to install i have got this: libcrypto.so.7 est ncessaire pou w6c-6.0-0.4.beta4.fc9.i386 I try to make a soft link to libcrypto.so.0.9.8k, but nothing; The question :-Is there a solution for that pb - did you know a better client for non native ipv6 connectivity?
I have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.
I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
My aim is to test on my computer some .jar games for cell phone before installing them on my Samsung GT-S5230. Unfortunately, the result of the following commands is not so happy:

Is there a way to get F10 (Gnome) to remember where my screen positions are? I keep having to move them over and over anytime I open a new application and tell it where I want it.
I'm running Ubuntu 9.10 on a Dell Inspiron 6000 laptop (intel Mobile 915 video card), with an external 19" HP monitor.
I "preferences/screen" I set the HP monitor to be on the left side. When I restart my computer, this setting is kept ok and the HP monitor works as intended (on the left side). But when I suspend the laptop and resume back, the HP monitor is moved to the right side and have to repeat the process os moving it in the preferences menu. What am I doing wrong/how can I fix it?
I want to find a utility that will allow me to manage the size, position of open application windows. Like tile, cascade of that other OS. So if I have my FTP, Editor, Terminal, Browser I can organize the screen ...
- The icons in my desktop is always changing randomly upon startup - Evince can't remember the last page i read before quitting - Unable to mount usb automatically (have to do 'mount /dev/sdc1/ /media/usb' and 'df -h' every startup)
All of these problems happened just recently. I thought they were coming from unresolved packaging but after upgrading and distro-upgrading from packman only, and gnome, the problems still persist. If it helps, here's my zypper lr -d
I have a system built and running in exactly the basic configuration I want, with my recompiled kernel, extra packages, special drivers, everything works, life is good. What I want to do is take this exact setup and create an image I can copy onto a bootable USB stick. Is there a way to essentially take the contents of my hard drive and copy that onto a USB stick and then boot directly from that? The use case behind this is that I am building an embedded system of which I may have hundreds of boxes with identical hardware and software configurations. Instead of hard drives, I am going to use USB sticks for cost efficiency and maintenance. My idea is that when it's time to upgrade, I could just image a hundred new sticks and go out and swap them.
My issue is that a standard LiveCD install gets me maybe 25% of the way to a finished system. I need to recompile the kernel for realtime support with my CPU, add some fidgety drivers for some specific hardware, and install a whole bunch of additional packages. I suppose I could create a makefile(s) to replicate all the manual steps of the buildout but that seems like a lot of unnecessary complexity IF I can just image that running system as it is.
I have a quad cpu with 8gb ram running SUSE 10 sp2 on a raid 5 XEN host server. I have created a 250 gb partition GWMAIL in the extended partition to be the disk space for the first virtual machine OES sp1 with groupwise 8.0. I have downloaded the OS .iso's to the desktop of the host server to use for installation. When I begin to install, it hangs for 5 to 10 minutes then gives me an out of space error.
