Fedora :: Unable To See Any IGMP Requests From IP Address
May 17, 2010
I am trying to send a multicast stream out from a Windows XP computer to my FC12 computer. I am using VLC for both the stream and the receive end of the process. Its version is 1.1.0-pre1 if that helps.As of right now I've used Wireshark to detect network packets, and I am unable to see any IGMP requests from the Fedora's IP address, whereas when I try to initialize a receiving stream on my Windows XP computer, I can see IGMP packets where appropriate. So the issue clearly lies with either VLC in Fedora, or Fedora itself, but I can't figure out how to narrow it down any further.
If it helps, I AM able to stream FROM my Fedora computer TO my Windows computer. Additionally, I am UNABLE to stream from my Fedora computer back to my Fedora computer (locally), despite being able to do that on the Windows side.

Our organization has several external IP addresses. I am behind 2 layers of NAT and the servers choose which IP address to route my traffic to. Can I specify which IP address to use when finally leaving the organizations network. I know that source routing can be done in IPv4 by adding some options in the header. But can I configure my PC to add these options automatically. I have both a Windows and a Linux Machine.

i've tried blocking ping requests with iptables.. and it didnt work Quote: iptables -A INPUT -p icmp --icmp-type echo-request -j DROP
also tried editing sysctl.conf.. which worked perfectly but after i restarted the system i was able to ping my ubuntu machine from my lappy here is what i added to sysctl.conf and then executed it with sysctl -p
Quote: net.ipv4.icmp_echo_ignore_all = 1 here is another atempt to block.. this one worked too... but again after the restart i was able to ping my machine.. Quote: echo "1" > /proc/sys/net/ipv4/icmp_echo_ignore_all

Is there a way of altering the time between password requests. For example after I login there seems to be a certain amount of time before the screen blanks out and a new request for the user password is asked. I would like to increase the time substantially.

I have a FC10 installation with GNOME and NetworkManager and a wireless card. Everything works ok. However, when I try and setup gdm to do autologon I get the NetworkManager applet asking for the password for the gnome-keyring to get the wireless details. Since I want to use this machine as a sever this is unacceptable as I won't be around to type in the password. I tried the solution at [URL] but this does not work. I still get the password being requested and the keyring password is the same as the logon password. Can anyone say if there is a workaround that works to get the NetworkManager to be able to read the gnome keyring without having to prompt me for it.

I want to track the number of requests that a file gets downloaded and viewed.
What I have is mp4 files on the server and they could either get played in flash player or downloaded via mobile or whatever.
I need to see how many times that files gets downloaded or viewed. Since its in a php page I am able to track the number of views. But I want to able to track the direct downloads.
I was thinking something along the lines of htaccess redirect to php then to file.
But that would mess up the player from playing the file I would think. I am not sure how to make that happen with the htaccess either though.

I seem to be having real difficulty downgrading my Wicd as I keep getting "Connection Failed: Unable to Get IP Address", and after having the trouble in another laptop (Ubuntu Mint) with the same problem...oddly enough the solution (other than buying another router) was to downgrade the wicd. butttt.... Now I not able to uninstall Wicd and therefore can't install the downgraded rpm file.Below is the error when trying to delete Wicd 1.7.0.2/ On another note,,, is there an easier one stop search for available software?, One that doesn't require an intimate knowledge of repositor

I just got a AWUS036H Alfa Network Adapter but there's like 10 folders on teh CD that it comes with, and there's read me's in about all 10 of'em, i have no damn idea which one to install. I went ahead and just did ifconfig wlan1 up and brought the interface up, went to wicd network manager and added wlan1 to wireless adapter
when i try connecting to my wireless router, it says resetting Ip ddress, something else with the configuration file, then obtaining IP address... it just hangs there for about 2-3 minutes and gives me an error... anyone else know how to set up this adapter?

Basically I am trying to set up my own server so that I can ssh into it from anywhere. I am able to SSH into my server when I use the LAN IP of my server but I am not able to SSH into it if I use the public IP address. I have read many threads and in my opinion I've tried almost all of the common fixes suggested. One possibility may be that my ISP has blocked port 22. I have taken this into consideration and sent them an email and I'm presently waiting for a reply. However, I highly doubt that my ISP has restricted acess to port 22. I would really like to be able to SSH into my server from anywhere.
1). I installed openssh client/server using the following commands:
Code:
sudo apt-get install openssh-client
sudo apt-get install openssh-client
2). I forwarded port 22 on my router. (see attachment for the settings)
3). I modified /etc/ssh/sshd_config such that my server has a static LAN address.
contents of sshd_config file:
Code:
# Package generated configuration file
# See the sshd_config(5) manpage for details
# What ports, IPs and protocols we listen for
Port 22
# Use these options to restrict which interfaces/protocols sshd will bind to .....
I then entered the command:
Code:
sudo /etc/init.d/ssh restart
4). I turned off the firewall using the command:
Code:
sudo ufw disable
5). Here is the output of the IP tables:
Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination

I have just installed Ubuntu 9.10 (64 Bit) and I'm trying my best to get this Linksys WMP300N wireless adapter to work.I have searched and gone through a number of threads here with some level of progress but I still can not get this to work.Adapter info is BCM43XG [14e4:4329] rev 01I have installed driver bcmwl5.inf using ndiswrapper and ndisgtk.I had absolutely no success trying to use network manager applet so uninstalled it and went with Wicd instead which at least sees my SSID network with a strong signal.My network is encrypted using WPA and I entered the passphrase which seems to pass authentication but it keeps trying to get an IP address until finally it just tosses a failed message.I feel as though I'm really close but it just won't connect.
iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

So I got Ubuntu 9.10 on my laptop working really neat and wanted to upgrade my desktop to 9.10 as well. So I reinstalled Ubuntu there and now I can't connect to my network anymore....
I have a usb wireless adapter (currently Sitecom as I bought a new one today to hopefully fix it, but ended up at exactly the same problem as with my old adapter). The network manager I'm using now is Wicd since some topics I was looking through were about malfunctioning GNOME network-manager (which I removed) and suggested to try this. The GNOME network-manager kept prompting to insert my WEP network key which was a correct one. When I removed all security from the network it didn't prompt anything anymore but just failed to connect. The Wicd network manager is so nice to tell me that it cannot obtain the IP address however, so I suspect that this is my main issue... but I have no idea what I can do about this? Tried using a static IP and then I get the message "Connection failed: Could not contact the wireless access point."
I feel powerless as my knowledge here is just lacking..

this issue which has suddenly occurred on both my Desktop and my Laptop. When I try to configure an IP address to any interface I get the following error....
uadmin@Ubuntu:~$ ifconfig br0 addr 192.168.10.1/24
addr: Unknown host
ifconfig: `--help' gives usage information.
uadmin@Ubuntu:~$
I get this for ethernet interfaces as well. I do not understand what is different as I was able to configure the ip address only the day before yesterday on the laptop..? The Desktop has had this issue for about 3 weeks now.
br0 Link encap:Ethernet HWaddr 32:70:40:91:06:25

When trying to copy my personal address to CouchDB I get this error: Unable to open address book. This address book cannot be opened. This either means that an incorrect URI was entered, or this server is unreachable. Detailed error message: Invalid source
I have been trying (since 10.04!) to sync my Evolution contacts. UbuntuOne seems to be the most promising way of doing that automatically, however, I completely fail at accomplishing this seemingly simple task. I have NEVER been able to successfully back up my address book to UbuntuOne. Note: all other sync works fine. It's just Evolution that is seemingly smarter than I am. Thing I have done to solve the issue:
- Upgraded from 10.04 to 11.04
- All three steps from this article:
https://wiki.ubuntu.com/UbuntuOne/FA...olutionSyncing
- Cuss and swear and roll my eyes, mutter a few unrepeatable curse words about Canonical and their mothers.
None of this has solved my issue.

I installed Wicd from the Slackware DVD and was successfully connecting to the internet for the past few weeks.I do not know if the following caused my problem or if it is something else that I did:All of a sudden (probably something that I did) the wpa_gui screen started to appear on my desktop. I just closed it.Today, in a moment of stupidity, I said "Who needs this wpa-gui thingy?! I know, I'll just use pkgtool to uninstall it. Then, if I need it, I'll just use pkgtool to reinstall it!" So, I did. After my next reboot, you guessed it, no wireless.
Wicd seems to do everything it used to do, except connect. I get the error msg "Connection Failed: Unable to get IP address." I see my 'connection' listed and it is still set to "Automatically connect to this network" but it doesn't.So, is it the wpa-gui app that I 'uninstalled' or is it something else that I might have done?

I recently setup motion on one of my computers with a USB camera. On that computer if I type [URL] I can see my live video. If however I type [URL] on that computer or any other on my wireless network, I get a page cannot be displayed. I checked that UFW was disabled and I am able to ping the motion computer from any other computer on my network. Also I am not sure if it matters but I do have apache installed on my motion computer as well. why I cant view my live video from different computers I am using Ubuntu 10.4 on all computers

Writing a program that finds the IP address of a host name. Sorry forgot to include the line numbers, but where the $$$ is where the syntax error is. The errors are syntax error before "{" token and syntax error before "if". I've looked throught the code for a couple hours and can't figure out what's causing it. The code is attached below.

I run an centos server. From the console I can ping google.com and get a reply. But when I ping another address say xyz.com, the IP address is resolved (11.22.33.44) but there is no reply. In the same network in our office from my desktop I ping [URL] and there is a reply.I turned of the firewall but still the same problem.
