Fedora :: Changing Host Names On Fc15?

Jun 22, 2011

I'm building a replacement service, and in the not to distant future, I'll need to change the host name and IPs (ipv4) (I'll also be doing this on the fedora 10 box I'm replacing)

I can look around and edit a bunch of files to make it happen, but there has to be an easier way.

Fedora Networking :: Resolving Host Names To IP Address ?

Jul 27, 2010

At work we run DHCP. hostnames have the format: computername.city.mycompany.com

I have a laptop runing Fedora 13 and a desktop I use for backups, etc. My laptop is named copernicus. Desktop is named galileo. If ping either hostname from itself I get back the localhost IP address. If I ping the fully resolved hostname it tells me unknown host. The desktop is exporting an NFS share I use for backing up work data. I need the laptop to be able to resolve host names to mount the share since we use DHCP. The desktop is dual boot and if it is booted into windows my laptop can resolve the hostname properly. What do I need to do in Fedora to get it to register a hostname with the DNS and/or DHCP server? Should the domain and the search path below both say the same thing?

Here is resolv.conf on the laptop (I am at home). The desktop looks the same, except for a different nameserver. Both computers can resolve other hostnames, just not each other.

Fedora Networking :: Local Host Names Without Domain Using Bind?

May 10, 2009

I want to use single label host names on my local LAN, without using any domain (at least no registered one). My machines should be named in a fashion similar to 'myserver', 'mydesktop' etc. so that i from a browser on any LAN machine may write 'http://myserver', and get the webserver on 'myserver' (so NO domain part, e.g. myserver.domain).

Do i need to create a DNS zone for each host or is there a way to put all host in a single zone, if so; which? Would such a name be considered a root domain?

Ubuntu Networking :: Assigning Host Names On LAN?

May 29, 2011

when I'm in my campus I saw things like this from tcpdump:

client-64-15.department.univ.edu
client-x-y.department.univ.edu
gw.nettokurabu.univ.edu

and my laptop got a name like that too (x and y being last 2 segments of the IP)out of curiosity, how to assign names like that to each IP? well, the names are not in dns records (can't resolve them to IPs)... when I set up (illegally) my on subnet with a routing software the addresses I used also already have their name without me configuring it before...

General :: Filesystems - Changing Device Names In /dev

Apr 25, 2011

I have many disks and volumes in my system. Some of disks IDE, some SATA.

Volumes on SATA disks cause me problems - I have them listed in etc/fstab, but on every boot, they have different name:

/dev/sdd* becomes /dev/sdb*
/dev/sde* becomes /dev/sdc*

etc. on every boot.

1) Why is this happening?

2) How can I prevent it?

3) If I can't, is there a workaround?

OpenSUSE Network :: Host Names Cannot Be Resolved Except For Ping

May 5, 2010

I'm running openSUSE 11.2 (Linux piura 2.6.31.12-0.2-desktop #1 SMP PREEMPT 2010-03-16 21:25:39 +0100 x86_64 x86_64 x86_64 GNU/Linux) and have a network problem. At work, ethernet works fine. When I plug it into my DSL router at home (which works with other computers), I encounter the following behavior: ping can resolve host names, however, traceroute and Firefox and Thunderbird cannot.
It happens for both wired and wireless connections.

General :: Get Windows To See Host Names And Vice Versa?

Sep 17, 2011

I have Windows and Linux machines on the same subnet. My router configuration correctly tells me both their machine names, and their IP addresses. However, when I try and ping a Linux machine from a Windows machine, or ping a Windows machine from a Linux machine, I need to use IP addresses rather than names. If I'm pinging a Windows machine from a Windows machine, or a Linux machine from a Linux machine, the machine name correctly resolves without any hosts file entries. Why is this?

I would have thought my router (D-Link DIR-655) would act as a DNS server itself. I see it has an option called "Enable DNS Relay", but from what I've read this won't help me. If it's relevant, the DIR-655 is used for internal traffic, with my ISP's Netgear DGN1000 used as a gateway to the Internet. It's on a different subnet though, and all my machines connect to my DIR-655, not the DGN1000. What do I need to do to have host names automatically resolved within my subnet regardless of the operating system that they're running?

Networking :: Internal Host Names Resolving Through External DNS?

Feb 6, 2011

I just set up my first ever bind9 DNS server running on ubuntu server 10.04. This server is also my gateway/dhcp server.

Here is what is weird: If I do a dig @8.8.8.8 dschuett-lmtl.scs.local from any of my clients it resolves?!?! Dig shows that it got the answer from MY Bind9 DNS server (and NOT Google's of course), but why is it still resolving when I'm telling it to use and external DNS server?

The other weird thing is that the SAME EXACT dig command above does NOT resolve internal host names if I do it from the Bind9 DNS server. - Which is what i would expect SHOULD be happening if done from the client machines...

Here are the dig results:

From any internal client:

Server :: DHCP: Logging Host Names In Log File?

Jul 7, 2009

What I am trying to do is log IP Address, MAC Address and the host name for records. So I can have a record of what PC got which IP address and when they got it. So far my search has yielded no results. It would not be that big of a deal as I could always look at the dhcp file, but it is generated dynamically (3rd party application using RADIUS and each user gets a host).

subnet 208.x.x.0 netmask 255.255.255.0 {
option routers 208.x.x.1;
option subnet-mask 255.255.255.0;

CentOS 5 Server :: Name Resolution Of Host Names Using Bind?

Mar 21, 2011

I installed bind & did not install chroot. I set up a fictional domain kelly.local. I am able to resolve FQDN (example: angus.kelly.local) in both dig & nslookup & ping on linux boxes.

I want to be able to resolve bare host names (example: angus) using bind. I get mixed results.

(1) linux boxes resolve bare host names & FQDNs just fine using nslookup & ping, but not dig. dig gives error:

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> angus

CentOS 5 :: Configure Sendmail To Accept Email Without Domain In Local-host-names

Mar 23, 2011

dammit... all that typing and I hit the wrong "submit" button. *sigh*

Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.

SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?

Ubuntu :: Computer Will Not Boot After Changing Host Name

Mar 16, 2011

I'm very new to Ubuntu and installed it (10.10) just a few days ago on a laptop I got for my girlfriend. The problem is that she wanted me to change the username and computer name that I have set up when installing, which I tried to do. I followed the instructions on this link to change the computer name/hostname: [URL]. Obviously I did something terribly wrong, because after trying to restart my computer I couldn't boot it. It freezes immediately after the BIOS screen - just displays a blinking dash in the top left corner. The same thing happens when i try to boot from a CD (I tried both Ubuntu and Windows 7 CD's. Resetting BIOS to default also did nothing.

Security :: Deny Host When Changing SSH Port 22

Oct 30, 2010

I have an Asterisk on an externally hosted vServer with Lenny. In order to further protect the SSH access I intended to change the Port number 22 to something like 55555. For this I changed the /etc/ssh/sshd_config file and restarted ssh. This caused unfortunately the following problems:

(1) The first login works but DenyHost writes now the IP in its list so that the second login with the same IP is blocked.

(2) With RESET_ON_SUCCESS = yes several logins were possible with the same IP, but later it also was blocked for some still unknown reasons.

(3) Files can be uploaded for being edited, but they can't always be saved. When they can't be saved the next login with this IP is blocked. It thus looks like the blocking can occur while being connected. When the files can't be saved it is however still possible to copy files from the computer to the vServer.

I add below the entries in the auth.log from a logout and a login. It shows further how suddenly the attempts to save files were blocked. After this session the IP used for it was blocked. I don't know where the message "Unable to open env file: /etc/default/locale" comes from. If I remember right I had these messages already before. I don't know how much that is really important.

OpenSUSE Network :: Cannot Resolve Host Names On Local Network?

Mar 9, 2010

I have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!

This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.

Fedora :: FC15 - Will Not Boot At All

Jul 4, 2011

Recently installed FC15 XFCE on my new hard drive in my laptop, bring it home from work and it wont boot up.

Only changes I made at work were removing the standard package manager, replacing it with yumex, and slightly changing the panels to more suit how I like to work. Other than that just a little browsing the web on work's wireless connection.

Now it will not boot at all. Pressing Ctrl+Alt+2 and the last command I see is "Started SYSV: Late init script for live image.."

Tried booting into the original kernel (rather than the updated one from when I first installed) and the writing is smaller so I can see an earlier message where it failed a process. This is relating to akmod_nvidia but I installed that a couple of days ago and have restarted a few times since without problems before.

"Starting LSB: Builds and install new kmods from akmod package failed, see 'systemct1 status akmods'service' for more details"

I do not even get a command like where I can type with Ctrl+Alt+2 to try running anything.

I tried adding "runlevel=3" to the end of the kernel line in Grub. Is that the correct way to try and force into command line?

Fedora :: FC15: Tsclient For RDP Connections

Jun 27, 2011

I have just upgraded my FC14 laptop to FC15 and although tsclient was 'transferred', it would not run and so I did not have a working graphical interface to make RDP connections.

As the app wasn't running, I removed it and then discovered that tsclient is listed as 'orphaned' and 'deprecated' in the repos, with the latest working version being for FC13.

Is there really no GUI interface for using RDP in Fedora 15 - I can't believe I have to drop down to a command prompt to run rdesktop!?

Fedora :: Remove Gnome3 In FC15?

Jun 28, 2011

I'm going to remove Gnome3 from FC15 and, possibly, install KDE. I'm not sure about the options I have for it:I saw I can remove just the gnome-shell package. This makes me wonder if it is possible to replace the gnome-shell functionality with a gnome-2 equivalent, getting some of the gnome2 back how much of gnome-related packages can I remove? For example, is it advisable to remove gdm in favour of kdm? Are there gtk/gnome programs that are "better" than kde equivalents and are thus best left untouched, along with their dependencies? finally, somewhat unrelated, do you know good tutorials for gnome2.X expatriates to learn modern kde?

Fedora :: FC15 KDE - How To Convert To Headless

Aug 15, 2011

I currently have an FC15 KDE, set up as I like it as a media server, and with squeezeboxserver (for Logitechs media system) running fine. But I'd like to set it up as headless - and it presently needs to have a monitor attached. No keyboard or mouse and it will boot to the login screen (so not a BIOS issue). I need to get it to boot without needing a monitor or requiring a graphical log in. I can administer via SSH and Squeezebox server puts up a webpage. FC15 doesn't use inittab any more, so changing run levels is fraught. I don't want to play with targets without a safety line ...

Fedora :: FC14 To FC15 Upgrade - USB 3.0 Not Working

May 29, 2011

I have used preupgrade to moved from fc14 to fc15. With fc14 I had my two usb 3.0 ports working. However, with fc15 my usb 3.0 ports are disabled. I have read the instruction at the common fc15 bugs doc and removed the kernel parameter xhci.enable=1 and also erased the file /etc/pm/config.d/xhci. Still the usb 3.0 ports are not working. I am using kernel 2.6.38.6-26.rc1.fc15.x86_64. I cannot use the 2.6.38.6-27.fc15.x86_64 since there no nvidia drivers for it.

Fedora Security :: FC15 And Iptable Rules ?

Jul 16, 2011

I don't know if FC15 has the iptable rules like the ones shown below by default or not but I wanted a second opinion about the safety they provide. Why is icmp accepted (INPUT rule 1) from/to all ip? and is it better to remove this rule? When the protocol is all (INPUT rule 2), does it mean from ip layer and above?? and is it required/safe to have this rule? The 3rd rule is to allow tcp-port 22 connections (ssh) to/from all ip. I think this is correctly set and required. The 4th rule in INPUT table rejects pings with the icmp-host-prohibited message; which I don't think is the best solution. Instead it can be set to silently drop icmp packets. Then, the FORWARD table uses reject instead of silent drop for forwarding icmp ping packets.

Code:

what do you think about the new rules and their order?
