Fedora Networking :: F14 Avahi Mdns Not Configured By Default?
Nov 23, 2010
Two machines:
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

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.

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've had a go with a netbook and 11.2. Installed ok and X configured KDE desktop with default 1024x600.
Minor. Most apps on running fit between top and panel but then you run their menu item like 'settings' or 'prefs' and its window size is coming up >600 in height. Some allow a scrollbar on the right but for those not, the result is not seeing the 'ok, apply, cancel' buttons. I did find that changing certain font sizes under System Settings both up and down and re-logging in sorted that for most.
If you click the top-left icon on a window you get to the special window settings and can see and change the geometry. However, for some that didn't respond to the font change above and seem to be hardcoded geometry-wise for a 1024x768 minimum, the result is a "squashed" window. Certain button options seen in the normal window are not there or the items are overlayed on each other.
Specific is Okteta the hex editor.Major. I don't use a wheelscroll mouse on other pcs. This netbook has a trackpad with the rightside 7mm or so having a scroll facility. In editor or Firefox running a fingertip on it will scroll the pages which is nice instead of looking and clicking in the scrollbar.
What is NOT nice, I found, is that if the cursor arrow is over a desktop patch and my finger hits that 7mm part of the trackpad when I want to move the arrow, it results in switching between desktops. I wondered what the hell happened when the apps and console I had up disappeared then reappeared then.OK this is the wonderful KDE4 where you can do anything and customise as you like. Well no, not about this. Funnily enough it shows up in the KDE handbook help about being an option in the desktop numbers section but of course isn't there. A fallback entry from previous help version it seems.
I've seen, and have some to make of, the general KDE4 crits but this one's a real WTF. So desk users with a wheelmouse doing some critical reading of some file or webpage could have that rudely interrupted just because their hand moves inadvertently? OK, maybe I should direct at KDE people, but is this fixable in the supplied 11.2 KDE4 or later KDE4.x ?

I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04.
The problem is that I would like to use a larger size display that is configured by default.
Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080.
This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation.
The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file.
I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily.

I have a few ubuntu machines in my house, 1 mythtv backend server with other services as well, 2 mythbuntu frontends boxes hooked up to tv's etc. I wanted to push the audio from my laptop out over pulseaudio to the machine connected to the AV equipment.
I could not see any other pulseaudio sinks in padevchooser... this lead me down the road to investigating avahi.
When I run avahi-browse on my laptop (hydrogen) it only returns the services published from itself:
Code:
$ avahi-browse -ta
+ wlan0 IPv4 byron's remote desktop on hydrogen VNC Remote Access local
+ wlan0 IPv4 hydrogen [00:1b:77:71:97:76] Workstation
[Code]....
My laptop has vmware on it, and I've changed the vmnet intefaces to not support multicast so avahi ignores them. but I'm still at a loss to why my laptop can't see the other machines on my network with avahi (mdns).

why my new Ubuntu 10.04 computer won't automatically advertise afp thru avahi to the network? This is a new install of Ubuntu 10.04, I downloaded and installed newest version of Netatalk, and the Avahi daemon. Both installed with no issues. (I followed instructions from articles on here) I can manually login to Ubuntu afp share from my iMac, by going to "Go to Server" and typing in the ip 10.0.1.3 and putting in the Ubuntu username and password. I just can't get it to advertise or broadcast itself to the network like it is supposed to using netatalk and avahi. I've followed all of the tutorials I can find on this, but nothing works. Even if I issue the command to restart avahi daemon, Ubuntu still isn't seen in the iMac's finder window? Because I can manually login to it, I am assuming that netatalk is working properly. I've even tried to issue the command to restart netatalk first, then restart avahi, but still nothing?

I've got problem with Avahi on my laptop. It can see the other machines and services on the LAN but not it's own local services and I have no idea why. The laptop (hostname: forseti) sports Ubuntu 10.10, installed aavahi-daemon, avahi-dnsconfd and libapache2-mod-dnssd. Firewall is disabled. Other hosts on the LAN are: magni (openSuSE 11.4 with lots of services published and visible from forseti) and freya (Ubuntu 10.10 with gnome-user-share up & running). Forseti can see the other hosts and their services but not itself. The other hosts can't see forseti. Checked both with nautilus and CLI's avahi-browse.

I got a new X201 which is running Ubuntu 10.04. While at home, everything is fine, at work, I encounter some issues with wireless. the signal cuts in and out repeatedly.Here's the output of ping. I set it to ping a server every 90 seconds, 10 times. So this is a snapshot of 15 minutes of network activity...
Code:
PING (REDACTED) bytes of data.
64 bytes from (REDACTED): icmp_seq=1 ttl=252 time=1.50 ms
64 bytes from (REDACTED): icmp_seq=2 ttl=252 time=2.13 ms
64 bytes from (REDACTED): icmp_seq=3 ttl=252 time=1.38 ms
[code]....
Also I tried this (from a 2 year old thread which was most relevant solution I could find):
Code:
Changing AVAHI_DAEMON_DETECT_LOCAL=1 to AVAHI_DAEMON_DETECT_LOCAL=0 in /etc/default/avahi-daemon has got rid of the irritating pop-up. Basically, every 5 minutes or so, for a solid 60 seconds or so I get no signal. I've tried updating the kernel, and doing apt-get remove avant-daemon, but still have problems.

I am wondering if it is possible to use avahi to resolve hostnames across a gateway. With gateway I mean a linux box with ip_forward'ing enabled to pass traffic between interfaces. The gateway connects two networks with all hosts running Ubuntu and specifically avahi-daemon. The gateway is not running avahi and I am not able to install it there. The firewall configuration on the gateway is not blocking any traffic between the networks. I am able to send UDP packets from a host on one network to a host on the other.
When I run tcpdump on a host and try to ping that host.local from a machine on the other network I see no traffic. This means that the gateway is not passing the multicast traffic along. Is there any special setup required on the gateway to allow this?

I am sharing some folders from my Ubuntu machine, using Netatalk and Avahi, over my network.I access these folders from my Mac using the AFP protocol.When all is well, my Ubuntu folders show up in Finder on the Mac and I can connect to them.But at random intervals, the Ubuntu folders will disappear. Sometimes they reappear a short while later.At other times, they wont appear until I go to my Ubuntu machine, and re-save (even if i don't change anything) the file:/etc/avahi/services/afpd.service.

I have a laptop with Ubuntu 11.04. Failed to connect my home wireless network, which is composed of a modem and a Netgear router.
ifconfig showing:
wlan0 Link encap:Ethernet HWaddr 00:24:d6:07:2b:a2
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:30238 errors:0 dropped:0 overruns:0 frame:0
TX packets:24005 errors:0 dropped:0 overruns:0 carrier:0
[Code]....
I do not quite understand how the virtual interface wlan0:avahi appeared. My guess was, my request "sudo dhclient wlan0" failed to get a valid ip, although I did not get any error message from running that command. I executed "sudo dhclient wlan0" again, but still no error message or network connection.
Later today, I tried to connect to a public wireless network. Still got the same error. But when I reboot my machine, no such problems.

I am trying to compiling avahi from src.rpm, and got this error: /usr/include/gtk-3.0/gtk/gtkapplication.h:57:3: error: expected specifier-qualifier-list before 'GApplication'According to bug651328 Comment #2,gtk3 in F14 is a dead-end, unfortunately. gtk3 requires a newer glib than f14 has or will have.So how was the avahi rpm compiled? And how can I compile it from src.rpm?

In a previous thread I had detailed an issue I was having with avahi not firing up properly at startup.As a bit of background: the services available on the server aren't advertising until I restart the avahi-daemon manually after startup - The syslog shows the daemon starting on boot, but it never seems to access the service file.I was wondering if it is possible that this may be a file permission problem?

I have recently installed netatalk and avahi-daemon on my lucid server but, much to my chagrin, I have to run
Code:
restart avahi-daemon every time I boot to get the service to advertise.
both avahi-daemon and netatalk have been added to the appropriate runlevels.

As mentioned in the title something is terribly wrong with my system. After some updates in the last 2 days Plasma keeps on crashing like a jackhammer. Kwin reports bugs and siece to work. That said I have no borders of any window I have opened and no Kickstart menu. (I am using KDE 4.4.1.) On top of it all when I rebooted the system it just hangs when it is supposed to start X and KDM. When I switch to verbose boot I see that Avahi Daemon has a "Failed" sign. I have tried with older kernels, but that did not solve anything. To be honest I am clueless on how to fix Avahi. The easiest way is to reinstall Fedora, but I would have stuck with Windows for that and where is the learning opportunity in that?

Using Unity in Ubuntu 11.04,
OK I've figured out to to set up a VPN, by clicking on the Networking Icon and clicking VPN Connections->Configure VPN and setting up the details... but how to I actually USE the VPN I set up??? I thought it would appear in the VPN Connections but no the only things in there are Configure VPN and Disconnect VPN!
UPDATE: Nevermind.. I rebooted and it appeared in the VPN Connections as expected

All of the servers I manage run a bare minimum footprint. Unnecessary services waste server resources and they are potential security risks if not updated.This is why I want to "absolutely" remove the Avahi-daemon.

I have configured bridging based on information from a few web pages Google found. Traffic is being seen (using tcpdump) on both interfaces that are configured. However, the traffic is not going between them. What could be missing?The bridging machine has 3 NICS: eth0, eth1, eth2. eth0 is configured normally with an IP address (I can login via ssh to it just fine). The bridge is named br0 and uses eth1 and eth2 (a dual NIC card for convenience identifying which NICs are the bridge).
A script executes these commands:
Code:
bash-4.1# /etc/rc.d/rc.bridge-up br0 eth1 eth2
EXECUTING brctl addbr br0

I have a hub with some VoIP phones attached as well as a machine that is used to record the calls. This all works fine as all packets coming to/from the voip phones are also seen by the recorder so it can process them as necessary.
What i want to do is put another machine between the hub and recorder and have it act as a transparent firewall. So far i've managed to successfully set up a bridge on ports eth1 and eth2 and all the packets destined for the recorder go through the bridge fine. The problem is that the bridge is acting as a switch so the packets from the phones are received on eth2 but don't get retransmitted on eth1. Is there any way to configure the bridge so that all packets received on eth2 are transmitted on eth1, i.e. have it act as a hub instead?

I did a echo 1 > /proc/sys/net/ipv4/ip_forward
I configured following rules in webmin:
Incoming packets (INPUT)

AcceptIf input interface is eth1 and state of connection is ESTABLISHED,RELATED

I would like an old desktop box to use my laptop as a router to access the internet. Here is my setup:
I have one ethernet port in the side of my laptop which I want to use to get internet access to my desktop computer. The laptop is connected to the LAN via a wireless link. Both systems run Linux. The desktop autoconfigures itself using DHCP. The laptop is a Kubuntu system. I do not have any crossover cables, though wireshark on the laptop sees the DHCP requests from the desktop just fine, so I doubt that I need one.
What do I have to do to make this work?
