Fedora Networking :: Changing Hostname Disables Autoconnect?
Feb 13, 2009
After installation, I changed the hostname of my computer, using system-config-network. However, after every reboot, it no longer wants to automatically connect to the network. The only way I could fix this was to remove NetworkManager-gnome and install knetworkmanager and use it to create a new connection. There was a flag there to autoconnect.
The other problem is that the hostname never shows on my network. My other PCs all have visible hostnames. One is an Ubuntu box and the other Windows XP. These machines can be pinged by hostname. The Fedora box can only be reached from the other PCs by specifying the numeric IP address.
I've checked the usual places and the hostname is correctly specified. Entering the 'hostname' command returns the correct hostname on the Fedora box. I am running Fedora 10.

I am coming across a strange error with my gateway. When I do a "ping", this is what I get below:k-63a5b848c6cb4:~ # ping simba PING simba.gateway.2wire.net (192.168.1.69) 56(84) bytes of data.

Kinda fed up with NetworkManager. Since trying the betas of F11 on my laptop, i've had endless bad experience with it.
Installed version: 0.7.1
Aside from the description below, please let me know what detailed system info you want to see (specific commands appreciated).
When i log in, the applet loads. However, it doesn't connect to the last Wifi connection i used. My SSID is hidden, so i click on the applet and choose "Connect to hidden wireless network". i see my stored connection in the drop-list. i select it, and all fields are greyed out, the WPA key is blank, and the Connect button is disabled.
Leaving that dialog, i delete my stored connection and re-create it manually, setting all the information correctly. i have DSL, using my DSL modem in bridging mode, and for some reason NetworkManager doesn't retrieve the DNS entries from the modem, whereas Windows does. So i have to set the connection to "DHCP (Address Only)" and manually add the IPs for my DNS.
However, the connection doesn't initiate, so i click the applet again and attempt again to connect to my hidden SSID, using the newly created profile. Same problem: no WPA key, all boxed disabled, and Connect also disabled.
The ONLY way i can get this thing to connect is by deleting my stored connection, clicking to connect to a hidden SSID, and create the connection from the New dialog. However, then i still have to go into Edit Connections and set the DHCP and DNS correcly before i can reach outside.
This is ridiculous, and i haven't been messing with any other configuration. i had a thread when F11 was still in beta where i had inconsistent results with NetworkManager. After thinking i got it fixed with some help, and discovering it wasn't, i decided to wait for the final release to see if it would work any better.
(automatically connect to the last active connection), consistently (connects when it loads at login every time), Otherwise, if there's a different connection manager, i'm open to that as well. Especially if the alternate connection manager can automatically retrieve DNS settings the way Windows can.

If i boot to fedora and boot back to windows i can no longer can access network/internet on windows! It says the network is disconnected. The cable is connected properly and this message is happening only because i booted to fedora 12 previously before booting into windows.
I did not have this problem with fedora 10, 9. recently i did an upgrade to 12 and this is one of the problems among the many other i am facing. In order to get internet back on windows i have to shutdown the pc and wait for a while and power on again to get network back on windows. the same issues exists on windowsXP64 and vista32.
I am connected to the internet like this pc->Realtek RTL8168D(P)/811D(P)->linksys router connected to pc by network cable --> DSL modem. the router connects to DSL by ppoe
My router's ip is 192.168.0.1. usually if i type this on my browser it will take me to the routers configuration. But a previous boot to fedora and i cant even access my router. its like it says "network disconnected".
why is fedora messing up my network connection? its pathetic that there is no OA in linux and it makes my life miserable.

I just have a simple question. When I installed Lucid a few weeks ago, I didnt feel very inspired, and thus left the host name at default. I just changed the hostname today, and I discovered that I can no longer resolve the host for ssh connections to the computer. When I changed the hostname files, I followed this guide: [URL].. Is there a file that I need to change regarding SSH that has a hostname in it?
Specifically, Im trying to ssh and VNC connect to the Ubuntu box from my iPhone. I have a PuTTY client installed on it (from the app store, called iSSH) and up until now, it worked.

I have installed Xubuntu 10.4 (Lucid) on a PC at my uncle's. He is the happy owner of a Netgear wg121 wireless usb-adapter.
I have followed the instructions concerning installation of the ndiswrapper here:
[URL]
The wg is up and running and everything seems to work perfect... except that, when I reeboot and log in, I have to issue the following commands again, to make the network initialize the wep-encrypted connection. If I do not issue these commands, the wifi-part of the Xubuntu network manager (I don't know the exact name of the program) is invisible in the menu or anywhere on the desktop. (It just says no network where the wifi should be appended). But when I issue these commands in a terminal, then the adapter (wg121) opens and connects to the network:
sudo depmod -a
sudo modprobe ndiswrapper
I have tried the command:
sudo ndiswrapper -m
in order to make Xubuntu connect automatically on opening, but no success. When i look through the log it says something about a .conf file, but not which and how, so I'm a bit lost.

I have a Fedora 14 machine, and I have an OpenVPN CentOS 5.5 server installed and running without issues.I've setup the Fedora machine to connect as a client to the server, and all goes pretty well using NetworkManager.What I'm not able to do is getting NetworkManager to autoconnect to the server upon user login. I have the "Auto Connect" marked, but nothing happens at boot/login.

I have a network of 2 WinXP machines and one linux box. I have fiddled around with the settings as you do when learning. The network is working. The network neighbourhood on the WinXP machines recognise the linux box and vice versa, (the linux Places|Network recognises the 2 WinXP). I can Ping the linux box using its hostname from a WinXp. But I cannot do the reverse. I get an 'unknown host' response. I can ping the linux to itself using its hostname.

I'm having an issue on two Fedora Core 13 machines where I can ping others by hostname, but the hostname resolution fails whenever I use ssh/scp/vnc/etc. I can still do these things by IP address, just not by hostname. RHEL5.3 machines on the same network with the same configuration do not seem to have this problem.
Here's the not-so-quick-and-dirty description of the situation:
I know that there is a virtual router at 192.168.31.1 and another at 192.168.30.1. I also know that there is another network (let's call it 90.90.90.0) and on that network lies a number of resources. By nature of this configuration, any machine on 90.90.90.0 can be accessed by any 192.168.x.x, but not the other way around. Beyond that is out of my hands and currently out of my scope of knowledge.
I have a dnsmasq server on 90.90.90.10 that operates as a secondary nameserver, another machine out of my sphere of influence is the primary nameserver (90.90.90.31).
The secondary nameserver on 90.90.90.10 holds the hostnames of our development machines. The problem is that in some cases, while I can ping by hostname all day long, services such as ssh, scp, vncviewer, etc all fail to resolve the hostname. In other cases I can do all of these things.
Every machine has an equivalent resolv.conf:
As an example, I will show the output of a handful of my development machines:
I also included columbia as a one-way test -- even though it cannot access 30.x or 31.x, they can access it:
columbia -- physical machine, Red Hat Enterprise 5.3, IP 192.168.100.200
Okay, so here are the various outputs. Remember, nibbler, discovery, and atlantis can ALL:
- Ping by IP address
- Ping by hostname
- ssh, scp, vnc, etc by IP addess
Additionally, the SERVFAIL reply from 90.90.90.31 is expected since my dnsmasq server is on the secondary server.
Note that the only machine that can both ping and ssh/scp/etc by hostname is nibbler, which also happens to be the only one of the three running RHEL5.3 instead of FC13. Other virtual and physical machines running on the 192.168.31.0 and 192.168.30.0 networks (all running RHEL5.3) work just like nibbler does. So the problem seems to only affect machines running FC13.
Final note: selinux is disabled, iptables is disabled, ip6tables is disabled.
Other than that, discovery is a brand-spanking-new install straight off of the FC13 DVD. atlantis has been around longer, but its just a file server so I haven't done anything too crazy to it.

This isn't really a problem or an issue but I'm kinda curious about it. I thought openSUSE generate a hostname like "linux-xxxx" when you install it and that was it. But for me it generates a new host name every time I turn on my computer. For example, right now it's "oseiler-linux" yesterday it was "mac-sophia". I'm wondering how it generates these kinds of hostnames.

I'm trying to ping another Ubuntu computer on my local network. If I try doing,ping <hostname>then I get the messageping: unknown host <hostname>however, if I doping <hostname>.localthen I get a response back. I was wondering how I can change it so that I can ping without having to append .localI've installed winbind and modified my /etc/nsswitch.conf file but this has made no difference.

I have an ubuntu 10.04 server with hostname "abc.domain.com". However, due to migration, we had to change to hostname to something else, "xyz".
I have done changing /etc/hosts and /etc/hostname and run /etc/init.d/hostname start.
Checking the hostname and all shows it is now using hostsname of xyz. However, email sending out is still using old hostname. We have some scripts that will send out alerts like failed rsync or hdd space full to my email account. But I see the sender is still "root@abc.domain.com".
How do change that to xyz? I am using postfix. I have edited main.cf and restarted postfix but no go.

I am new to Ubuntu 10.04 and so far I love it! I recently created a LiveUSB and I am running Ubuntu from my USB drive with preserve mode.
I changed the /etc/hostname and /etc/hosts files with my new hostname and everytime I reboot those files are going back to original state and change the hostname back to ubuntu...
The rest of my installed applications and settings are preserved... Is there a way to permanently change the host name?

I do a lot of work on the Seattle bus system on my Jolicloud netbook (I'm a hardcore Kubuntu user, and Jolicloud is based on Ubuntu Netbook). All Seattle buses have free wifi. They have a name scheme like "ST_9545" for the 545 from Redmond to Seattle, or "ST_7483" for whatever. You get the idea...all the free wifi on the buses are "ST_****".
Here's what I want. I want to autoconnect to whatever my current bus's wifi network is based on a name scheme. "ST_****" will be the name of the open wifi network on the bus. How do I set it up so my netbook automatically finds and connects to an open wifi network with that specified naming schema?

Running Fedora 11.
Did get a Kimsufi dedicated server through [URL] When I did get it the hostname resolve does not work.
I have never got any of this problems before so this is my first time playing with the network settings.
Nothing works! Lynx, wget, yum and so on. IT works if I do enter the hostname by its IP. But thats not working in the long way

When I use Ubuntu, my DSL modem correctly gets the hostname I call my computer "mertensia", but I'm having issues with Fedora. Yet, when I look at the name assigned by the modem (using URL... in a web browser),I need the PC Name to be mertensia, because otherwise it will complicate how I ssh immensely.

I have 4 installations of Fedora 14 running on a Win 2008 R2 server in Hyper-V.
When I try to ping my desktop or the host server via the hostname from within any of the Fedora installations, the ping fails. I can ping by IP without issue. Also if I try to ping the VMs from my desktop it fails. I have an XP VM setup that I can ping without issue via hostname and IP.
All of the VMs can access the Internet without issue. I have disabled all firewalls on all systems with no luck. My desktop can ping the Hyper-V server without issue so it would appear that the problem lies with the Fedora installations.
My resolv.conf

Does anyone have anything I can try to get the name resolution working?

So everything seams to be fine on my F10 boxes networking. I can ping computers on the network with both LAN IP addresses, and their hostnames. However, I can only access my F10 box with a LAN IP. In windows, I go to view workgroup computers... only the windows systems. If I go to the F10 system with samba via the IP address it works fine, just can't get to it with a hostname.
I'm wanting a static IP of 192.168.1.22. And on the windows workgroup "workgroup".
I'm new to doing things with linux that are remotely difficult... and well, this has proven to be. I can't work out if this is a SMB problem, general networking...
smb.conf (I've ommited the top info segment due to forum character limit, as well as the SELINUX notes)

Yesterday, while trying on establishing mobile broadband, my hostname changed, and I can't make it yet. My /etc/hosts is
1 127.0.0.1 pc-194-101.fysik.uu.se localhost.localdomain localhost
2 127.0.0.1 pc-194-101.fysik.uu.se roddur
3 ::1 localhost.localdomain roddur
The second line I edited but after a reboot it inserted the first line all automatically and my /etc/sysconfig/network is
1 NETWORKING=yes
2 HOSTNAME=roddur
What I have to do if I have to change my hostname to "roddur"?
