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.
View 1 RepliesI cannot uncheck the "Change Hostname via DHCP" box because it is disabled. Next to it says "No interface with dhcp". How can I fix it? I'm using OpenSUSE 11.3/KDE4
View 3 Replies View RelatedI 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.

How do I set $HOSTNAME to dynamically update with the hostname that is specified for the ip in DNS?
View 3 Replies View RelatedI 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?
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'm facing bit of a conundrum with my new server. It is essentially a distributed-virtual Plesk Virtuoso container with a rather simple LAMP setup (PHP5 etc) and virtual hosting. Running 10.04 LTS.
The issue is that on each reboot, the /etc/hosts and /etc/hostname files are reset with their original configs causing the virtual hosting to break, i.e. rather than hosting the vhosts correctly, it essentially routes all traffic to /var/www, or essentially 000-default ~ this beats the whole point of vhosting in the first place!
Is there any way to get around them being overwritten at boot? A very crude workaround would be to set a script to load at boot via init.d and have it rewrite both files to their correct configs - of course, I have no idea as to the point during boot at which they get replaced.
Before reboot,
$ cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 172.20.10.22
search mycomp.local myhost.com
After reboot, the search path in resolv.conf is overwritten by the hostname.
$ cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 172.20.10.22
search penguin
I have installed CrunchBang, then I moved the /tmp and /var to different partitions (I like to put these on reiserfs) the reason I did it after the install is because CrunchBang's installer doesn't give me the options to create reiserfs partitions during install (but does recognise reiserfs as I can manually mount them). Also these two partitions are logical.Anyway I have Windows 7 and Ubuntu 10.04 already installed and working fine but CrunchBang always changes the UUIDs of /var and /tmp when I reboot. Is that even possible I have also tried using the old method of /dev/sd** but of course that gets changed as well.
View 3 Replies View RelatedI was having a discussion with someone who asked me whether a Linux OS has to be rebooted when the hosts file is modified. From personal experience, on Windows I change the file but don't reboot and I've seen others do the same thing. I assume Linux has no exception(s), but is there any reason why a reboot is not required (to at least justify my actions)?
View 2 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'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.

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.

View 9 Replies View RelatedI've a little trouble: I reinstalled on my notebook OpenSUSE 11.3 yesterday and I'm unable to change the hostname. I modified it, but when I type on terminal
Code:
uname -a
it doesn't give the right answer but returns
Code:
host
I don't know where I wrong because I did this action many times with Opensuse 11.1 and 11.3 without any problem.
I managed a first installation of SUZE 11.2 from a mag distro - downloaded the iso file - burned the dvd, installed again, looking to retain the host name for this computer. But for the second time I get a linuxXXXXX sort of host name! No chance to set my preferred one up. I like what I've seen of SUZE so far and am happy to move to it sort of permanently. This legacy hostname helps me keep sane in networking matters though and I have yet to configure a networked laserprinter and add another computer. Can I re-set the hostname to my selection without harming the whole set-up?

I installed openSUSE on my notebook with an usb drive using openSUSE 11.4 KDE LIVE iso. The installation process set the name to "linux-ygrl" which I don't really like. (I probably just missed the setting during the installation.). I tried to change it through YaST -> Network -> Hostnames and I set everything where needed to the new name and restarted but the changed weren't applied. I searched the web and found out about the /etc/HOSTNAME file which still contains "linux-ygrl". Now I could change it manually but I was wondering if there is a GUI for it?
