I did a new install of Fedora 14. This is my first time using Linux seriously and I am trying to figure it all out.
I am able to ping my hostname of sinbad only from the linux system itself. On all my windows boxes, I am not able to ping it. I can only ping the IP address.
Here is /etc/hosts:

I disabled the firewall, disabled SELinux, and still not able to ping it.
Here is the info from ifcfg-eth0 :

I don;t have physical access to the system and it is a server located in Europe. Fedora release 10 (Cambridge) is installed in it.
I am trying to share directories between two F12 machines on a local network with a router box doing DHCP because not all machines on all the time. Web access is fine and local ping and ssh works but telnet doesn't. I have never succeeded doing mounts. So I have been searching for things to fix the above and have just tried rpcinfo. If I do this :
rpcinfo -p 192.168.2.2 it gives rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host. Does that suggest that actually there is an installation problem? So I tried "yum provides portmapper" and that gives "No Matches found".
i am writing a script to know the status of the server whether it is accessable or not. i use ping. But sometimes the server is pingable but the SSH didnt work., is there any way so that i can check if the SSH (port 22) is working or not after ping that server.
View 1 Replies View RelatedI have installed a Netgear WG111v3 wireless USB networking adapter on an OpenSUSE 11.3 system. I'm using ndiswrapper to run the Windows driver. Using the "Network Settings" GNOME applet (says "Network Settings - YaST" in the title bar) it shows that I have the adapter installed as wlan0, but it's not connected. However, if I go to the "Network Tools" applet (says "Devices - Network Tools" in the title bar) and select "Wireless Interface (wlan0)" from the drop-down, it says that I have an IPv4 address of 192.168.1.104. This is a plausible address that my router could have served. However, I cannot use the network interface from the box itself.

Luckily I saved the old hosts file and copied it back and all is now well. But I'd like to understand why, particularly as I will need to change myhostname in the future.

On every machine that SSHes in, the connection gets dropped randomly between immediately, and 30 minutes into the session, while the user is actively using the remote system (typing, etc). Before, during and after the disconnection, the system responds to pings regularly (0% packet loss).It takes about 5-10 minutes before I can make an SSH connection again.I have tried restarting SSH on the server and rebooting the server. I even removed and reinstalled sshd and it is still happening.What might be causing these random disconnects and how might I solve this?
View 1 Replies View RelatedI 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.
View 7 Replies View RelatedI'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.
I am installing ISPconfig on a Ubuntu server 9.10. When i write hostname -f i get the unknown host message.
View 4 Replies View RelatedDoes a network install assign a pingable ip during installation? I am trying to verify why I get an error during installation that "stage2.img" cannot be found and I'm guessing that since I can *not* ping the static IP I assigned, that the network functionality is not working during the install process. Can anyone confirm if I should be able to ping a system during installation using the assigned static IP?

View 2 Replies View RelatedI 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 just built out an Ubuntu Server 10.04.
My problem is setting the hostname. I cloned the machine, then normally on the clone, I would change the /etc/hostname and /etc/hosts file.
However, when I do this, upon restart, I get the message, "init hostname main process (some process number) terminated with status 1"Then, when the machine finally boots, the hostname is set to (none). Literally has braces like: user@(none):
I've tried: sudo hostname machine_name but it says can't resolve hostname (none).
I've Google'd around a lot but can't get it. It may have something to do with 10.04? I have been using 9.04, 9.10 with no problems.

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.
View 4 Replies View RelatedI 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.

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...

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"?
I got a diferent domain. I got a modem-router (192.168.1.254 ) thats connect my computer with apache (192.168.1.68) I got dinamic dns with inadyn to update the ip adress for my domains. My question how to edit the hostname file (/etc/hosts)?
[Code].....
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.
At school can connect to my computer via SMB/Samba and VNC from the Windows Machines, but not by hostname (I still cannot VNC in at home on my desktop computer and have yet to try Samba there because I wanna setup Samba there from the comfort of my laptop and therefore need VNC first). How come I cannot access this machine by it's hostname?

first time user of F14 here. Used PCLinuxOS so far. Installed F14 fine , got samba up, set the hostname of the box to fedora.linux BUT when I connect to my wireless router (Belkin) the hostname shown in the routers DHCP client list is different:
Router shows:
IP Address-----Host Name-----------------MAC Address
192.168.2.4----ralf-FK790AA-ABA-m9---00:22:5F:17:dE:98
In terminal it shows
[dagaz@fedora ~]$ hostname
fedora.linux
[dagaz@fedora ~]$
When I search the forum or google, I end up with hostsfile or samba howtos. Those settings all show the right name : fedora.linux Why does the router show ralf-FK7 etc..? and where can I change it?

I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused
