Fedora Networking :: Avahi MDNS Works Then Stops Working?
Jul 8, 2011
F15 current
avahi-daemon installed
nss-mdns installed
firewall totally disabled (for now while testing)
connected to network wirelessly
For perhaps 5 minutes I can either ssh into or from the F15 computer using:
ssh chris@macbook2.local
OR
ssh chris@f15.local
Works fine, no problems. And then in about five minutes it work resolve in either direction: ssh: Could not resolve hostname f15.local: nodename nor servname provided, or not known
I can still ssh in using an IP address. So I do:
[chris@f15 ~]$ service avahi-daemon status
avahi-daemon.service - Avahi mDNS/DNS-SD Stack
Loaded: loaded (/lib/systemd/system/avahi-daemon.service)
[code]....
*sigh* No that's not it. I just found no mDNS service in or out of the computer 3 minutes 26 seconds after restarting it, no additional items in messages.
fedora.local = F14 default mingisapsycho.local = Mac OS X 10.6.4
I want to be able to ssh/scp between these two machines using:
ssh -l login fedora.local and ssh -l login mingisapsycho.local
rather than using IP addresses. Neither of these works, from either of the two machines. This does work between Mac OS machines. And I can ssh if I use IPs. So it seems that by default Avahi is not configured even though it is running? I really don't understand. By "does not work" I mean I get on both machines: ssh: Could not resolve hostname blah.local: Name or service not known
recently i notice this warning in my /var/log/messages avahi-daemon[4335]: WARNING: No NSS support for mDNS detected, consider installing nss-mdns! but i can't install it yum install nss-mdns No package nss-mdns available.
I have install fedora11 live and the mouse work well when installing.When you reboot the mouse works ok until the welcome screen apears then the mouse stops working and I cannot continue with the postinstall. I have a 1TB usb externalHD that I am installing fedora11 and have partitioned it so that I have 500Gb free for fedora, system is doucore 2.4,4gb RAm, I tryed doing this with three differend mice and connectting the mouse to different usb ports
I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?
I have just installed Fedora 15 xfce on my desktop. When I 1st start my computer my RaLink RT2870 works but after a while it disconnects and won't start again till I restart.
I can't see any pattern I am doing to make it stop. I been doing various tasks when it stopped working. I don't what command prompt or configuration file to look for or what to configure in the file.
I have two ubuntu 11.04 laptops that today stopped working with my home wifi, but my windows laptop works fine. These same ubuntu laptops connect fine to iPhone wifi hotspot.
I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.
I can't seem to figure this out. I've got a DOS disc that loads up a network share (my Samba server running Fedora 10) - connects to the share, runs ghost.exe from there. Everything runs perfect for about 2 minutes, then my thoroughput drops to 0. Sometimes, after about 40 seconds, it'll resume imaging. Most of the time, after about 40 seconds, Ghost gives me an error stating 'not enough free space on the destination disc' - This is a raid 5 3TB array that I'm ghosting a 6.0Gb HDD to! lanman auth = yes and client lanman auth = yes are already set up - I can connect fine, but it's almost like Samba hiccups and drops my connection!
I log on and Network Manager shows no wireless adapter.
I go to System > Administration > Network:
There are two entries in the Devices tab: Wireless and Ethernet
As soon as I double click the Wireless device and the configuration pops up, the device starts working (no changes to the settings are made)
I have the following set to ON: - Controlled by Network Manager - Activate device when computer starts - Allow all users to enable and disable this device
I have 3 computers connected to a router; the ip addresses are assigned by the ADSL provider via DHCP. One of the 3 computer has a printer connected. In Fedora 9 I used to print from the other. 2 computers via CUPS by defining the ServerName in /etc/cups/client.conf as assigned by mDNS (the one with the .local suffix). It seems that in Fedora11 the game dos not work anymore; the connection is forbidden unless, you put the IP address of ServerName in /etc/cups/client.conf. But this is upractical because the IP address is not fixed. (DHCP) A workaround is possible because ping on the name assigned by mDNS shows the IP address; if you capture the IP address, it is possible to create /etc/cups/client.conf with the IP address at boot. (A suitable script can do the job).
I'm having some problems with wireless, it works fine on boot but after a while pretty much randomly, it can be a few days or it can be a few hours, it stops working. I'm not sure which command would tell you what and it would take a little while to debug it because like I said it's random, but if anyone knows what to do please tell me! I'm on Lucid Lynx 10.04.Another something that's really bothering me (But not related to wireless) is that for some reason when I restart my computer, the top panel keeps changing the applets locations.
I have created a Samba share, using the fantastic Webmin tool. I have a network media player which can connect to my router, and then access windows (samba) shares. Most of the time, it works fine - it's able to stream HDTV wirelessly across the network. However, every so often, it just stops working ... the media player sees :
Network, then WORKGROUP, then FILESERVER-1 (machine name), then Media (share name), then Video (subdir, then TV_Shows (subdir), then MyShow.AVI ... just hangs
if I use the Webmin tool, I see multiple samba connections all from the media player. Restarting samba seems to have no effect. The only way to fix it, is to reboot.
logfile I can check, or a setting I can tweak to fix this issue ?
When it get like this, trying to access the share from a windows machine, just gives me an error saying it can't find the machine. But when it's rebooted, it works fine.
I have mapped the "nobody" linux user to "guest" which is what the media player is defaulted to login with (it's primarily sold as a "Windows" media player), and using Webmin I have assigned the "nobody" user read-only rights to the samba share. It worked fine for 6 months, until I added this new drive.
This should be easy for the Ubuntu Gods to sort out:
I have a Sabrent USB 802.11N adapter. (I am using 64-bit Ubuntu in all below)
I plug it into a 9.04 box and it works fine. Plug it into a 9.10 box. Network manager sees it and can attach to the network, but has 0% signal strength, no internet.
Rebuild the 9.04 box with a fresh install to 9.10. 0% signal, no internet. Try 10.04 Alpha 2, 0% signal strength, no internet.
Rebuild same box down to 9.04. Works perfectly. 100% signal strength. I do all updates and then the upgrade to 9.10 using the USB. Everything works fine until the reboot. Then, USB connects, but 0% signal strength, no internet. Oh! ifconfig says the wlan0 interface is up, but it has a random ip address.
I don't mind using 9.04 because for the forseeable future, the box is just going to count aliens for Seti, but my wife wants it off the counter and I would like to upgrade someday.
I have an Intel PRO/Wireless 5100 AGN [Shiloh] on my HP Pavilion dv7 running a fully updated Lucid (10.04).I can connect to the wifi on my smartphone and I have no problems at all.However, after a recent update I found myself unable to use my home wifi connection.Once connected, I can usually transfer about 1 MB of data and then nothing else will go through.# uname -aLinux lappy 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 08:03:28 UTC 2010 x86_64 GNU/LinuxSince the home wifi router, a Linksys Wireless-G SRX, is a bit more advanced than the wifi capabilities of the smartphone, I'm inclined to think there is some feature being used that is now broken in the iwlagn driver.I've tried to disable the "11n" support with this:
but the problem continues even after that ... is there something else I can try to disable?r some way of getting the details of these two connections to see exactly what the difference is?
I upgraded to the newest version of Ubuntu a few months ago, and ever since then, the ethernet connection to my router stops working when I restart the machine. It eventually comes back, but after varying amounts of time. Sometimes 20 minutes, sometimes 2 days.
Restarting the computer and cycled reboots of the router don't seem to have any beneficial effect, at least that I can detect.
The light for the slot on the router does not light up like it normally would, so it's almost like the OS doesn't even recognize the network card.
New Toshiba laptop dual booting with Windows 7. I really like MM 10.10 and most things are working great! Periodically I will be web browsing and I lose connection. At first I thought it was Firefox but if I try to disconnect wireless and reconnect it will no longer connect unless I reboot. My network is hidden but Ubuntu finds it no problem on a fresh boot and connects per my settings and it is not a network problem since I can connect to Windows all day long and the rest of the family never has problems.
My wirless device is: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)n and all OS updates are applied that I can find. I am thinking about un-hidding my network since years ago that used to be a problem with Redhat and even early Ubuntu but beyond that I cannot think of what else to try.
I'm currently working with Ubuntu 10.10.I wanted to add a default route to a gateway named ppp0.I did it with the command> route add default ppp0It works ok. But then from time to time it suddenly stops and I have to go back again to the server and retype the command. I'm clueless as to why is it happening. I can assure no one is working at the server or doing anything over there.Does anyone know causes that might be triggering route default to stop working?Btw where is the best place to add this command so it will be executed automatically on start-up and without needing to login to the server?
i am getting some troubles with WiFi. I got a Lenovo G550 with a BCM4312, at first i found some troubles making it work but i managed to find a proper driver and it is working "fine" Every 5 minutes or so my WiFi freezes and internet stops working. I don't get disconnected from the network, but until i don't reconnect to it, internet will not work.
Rare thing is, i realised that this happens ONLY when my notebook is plugged in. When it's working on battery, this does not happen. If i use it on battery it works for 30-40 mins (or more) and 3 minutes after i plug it in, it just stops working. I'm using Ubuntu 10.10, if there is any information i could give, just tell me. I also have a Windows partition and this does not happen there, either plugged in or on battery.
I have a Trendnet TEW-649UB Wifi N dongle, and I'm using the latest Realtek firmware downloaded from their website. It works ok, but everytime, after an hour or two, the blue light turns off and the dongle stops working. I have to unplug it and plug it back to bet my network back up.
My Ubuntu when i start it up, go to the wireless networks , try to connect to my network it trys to connect stops than says disconnected. My internet card is a Cisco Aironet wireless (idk the model number)
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I am using the routing multiple upstream providers solution available on internet using iproute and gwping script. It works great but the problem I am facing is;
Code:
ip route add 192.168.15.0/24 dev eth1 src 192.168.15.2 table ptcl ip route add default via 192.168.15.1 table ptcl ip route add 192.168.16.0/24 dev eth2 src 192.168.16.2 table nayatel ip route add default via 192.168.16.1 table nayatel
I'm running Debian server 5.0.6 and the latest stable version of Apache. I am hosting a website and it will stop responding after an unknown amount of time. In order to make the website work again I have to run /etc/init.d/networking restart. The server is running a static IP address and is not resetting when the website goes down. I don't know where to start looking.
This holds true in Transmission and NOT in Vuze. UPnP is enabled, ports are randomized and open each time. Pings to outside still work fine, but I cannot browse to websites (404 errors) when the app is running. I'm stumped, is Transmission locking all other in bound traffic/ports except the one it wants to use?
Previously my wifi has worked just fine in 10.04, but as of recently I keep losing my connection after leaving my laptop on for a while (and this happens sooner and sooner each time, used to be daily, now it's every few hours), I can no longer see any networks at all, and I have to reboot to get it working again. I haven't even installed or removed any packages lately, so I'm not such what might've caused this to break all of a sudden.
I am trying to get a network bridge configured but every time I make the changes and restart networking (or reboot) eth0 appears to come up OK but I can no longer talk to the outside world via it. With no bridge defined, I can talk to the web using either wireless or wired; wicd is configured to switch to a wired connection when available (got rid of Network Manager. It didn't recognise eth0(!)).
I want to use the bridge so virtual machines (LXC containers) can talk to the web when the machine is wired to the wireless router. Eth0 gets its IP address (192.168.1.4) via DHCP from the router and I want to bridge to another subnet, 192.168.154.n say, and the containers will have fixed IP addresses 192.168.154.101, 102, 103 etc.
I'm trying to get internet set up on my grandad's laptop (sony pcg-f590), which has a fairly old pcmcia belkin 54g wireless card. I've installed the relevant bcmwl5a.inf driver through ndiswrapper, and for a time wireless worked so I installed updates through update manager. however after restarting the network manager menu comes up with "wireless networks disconnected" and no list of networks (I know there are because my laptop works and his is sitting next to the router!). The light is on on the network card so I know the laptop is talking to it. Unplugging and replugging the card does nothing, and neither does restarting again.
After a while, my connection suddenly drops and I'm no longer able to see any networks or anything. The only way I can regain my connection is to reboot over time this happens, which is a pain. I've searched around and can't find any fix for this card.
