Ubuntu Networking :: Ipv6 Link-local Address Not Configured On Eth0 (server)

Feb 18, 2010

I added an init script numbered just before bind9 starts, which needs to see the ipv6 link-local address on eth0. Sometimes this address is not configured, yet. In all cases it eventually is configured.

I am unable to find any script that is configuring the ipv6 link-local address (which is in part based on the MAC address). Does anyone know if there is some script or program that is supposed to be doing this, or is it an internal kernel function?

One workaround I am considering is making this init script go into a loop around sleep 1 to keep checking for the ipv6 address. But I'm concerned this might cause some problems. Any suggestions? I don't want to let it move on to start bind9 until the configuration this script does (more ipv6 addresses) is done.

This is on Ubuntu 9.10 server (for which there is not a prefix choice).

Networking :: Referencing Hosts By (special) Hostname For IPv6 Link Local Address

Apr 30, 2010

I can reach other hosts by means of their global addresses by either the IP address or hostname (that has the global address). What I want to (also) do is have a hostname that references the IPv6 link local IP address (an AAAA record in DNS, or just the fe80::<whatever> address in /etc/hosts) and use that host name in commands to access that host. The problem is, an interface ID is needed when making such a reference.

It sure looks like the programs just pass the host name string on to the resolver library, which does not understand the significance of the '%' even though it could find and see that the name preceding the '%' is consistent with that being an IPv6 link local address (e.g. the logic could have been "split at first % and see if preceeding name is found as a link local address and accept that if so, or ignore the split otherwise" ... but it isn't). Is there a different syntax for this ... or was it overlooked in the design of programming around IPv6?I want to be able to address a host by its link local address, while still using a mnemonic instead of having to type the IPv6 address.

Ubuntu Networking :: Homepage Routed To D-Link Router Login Page On Local Machines?

May 20, 2011

In addition to 2 "desktop" machines, I recently set up an Ubuntu Server with Apache2, but when I try to access my www.homepage from a machine locally connected to the same router (via both wired & wireless interfaces), I am directed to the Login page of the router, not to the www.homepage. Yet, when I access the www.homepage from elsewhere, my www.homepage is accessible.

I can browse to my www.homepage by entering the local IP address into browsers on both local machines, so I know the machines are talking to each other. Just not letting me get in via normal internet browsing channels.

Server: Ubuntu 11.04
Webserver: Apache2
Router: D-Link DIR-615
IP Address of: 192.168.0.110 (reserved on router, static on server)

[Code]....

Ubuntu :: Alarm In Evolution Or Online - Reminder System?

Oct 2, 2010

I need an alarm / reminder system for all the crap I have going on. I want one that will pop up and remind me of a given task. Sounds, bleeps, rings, bells, etc., would also be great. Doesn't evolution have such a thing? IF not, what about online options. But I really prefer sg on this computers so I can still get the reminders when I am offline.

Ubuntu :: Can I Make Internal System Speaker Beep For A Calendar Alarm

Jul 7, 2011

I live in a crowded area so I have to use headphones almost all of the time. I just leave them plugged in so when an alarm goes off from Thunderbird or Evolution, I can't hear it. Is there a way to get some use out of my internal system speaker and have a reliable calendar-event-reminder and alarm? I'm talking about the one that will beep from inside the computer even if you have headphones plugged in.

Networking :: Can I Use NAT And Some Local Hosts Without It On System Box

Aug 7, 2010

I'm using NAT on an AP with linux. Is it possible to route an OUTGOING host not over NAT?

I'm using SNAT but could also use MAQUERADING I think. Because both are in POSTROUTING table and this table is the last one I don't think there is a solution or is there any solution?

Background:
I'm using a local VoIp client which I want to have an own ip for routing question in my network but don't want all other local machines as seperate ip's because if done so i.e. without NAT the routing table is very complicated ...

Ubuntu :: Link To File On The Host System - Error "Invalid Cross-device Link"

Ubuntu Networking :: Mount To Vista Needed For Apache - Symbolic Link Not Allowed Or Link Target Not Accessible

Apr 26, 2010

I have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf

[Code]....

The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.

log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html

The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.

Ubuntu Networking :: Can See All Devices On Local Network And Their Local Ip Addresses

May 16, 2010

I'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)

Ubuntu Networking :: Unable To See Local Web Sites From Local Network

Jun 28, 2011

I have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

Ubuntu :: OpenMotif : Create Network Location Link As Local Filesystem Location?

Apr 26, 2011

I'm working with a program that uses Open Motif to create all of the widgets, including the Open File dialog box (obviously). However, Open Motif being kinda old-timey, 80's vintage, and for the most part now an abandoned project, it is quite clunky. So, actually what I need to do is to open some files located on my work server. I have already successfully connected to the relevant server directories with Samba, and with programs built with GTK+ (such as GIMP) I can open files across the network because I have created a bookmark in Nautilus, and those bookmarks appear in the Open File dialog box created by GTK+. Now, Open Motif is different: it doesn't see network locations, orNautilus shortcuts. When I type "smb://serveripyadayada" in the search folder, it really doesn't like it and complains. So, what do I do? Can I get somehow Open Motif to open a network location? Or can I do a run-around and place a shortcut in the file system that points to the network location?

Software :: Verify Directory On Remote System Available To Local System

May 5, 2009

The code listed below is an excerpt from a script that I am writing. The goal is to verify that a directory on a remote server is available to the local system. If that is not the case, a log file is written, and all filesystems that were previous unmounted, are remounted on the local system.

Code:
# # Unmount all NFS mounts prior to the archive process.
umount -a -t nfs
# Mount the remote directory (NFS) prior to running the make_net_recovery script.
# Make sure there is a <remote server> folder located in the /mnt directory. If it is
# not already there, create one.
mount <remote server>:/<local system> /mnt/<remote server>

# Verify the remote directory (NFS) is available. This directory is needed
# as it is the destination for the iso images. If it is not available, stop
# here, and write the results to a log file.
df |grep <remote server> > /dev/null
RC=$?
echo $RC

if [ ${RC} -eq 0 ]
then
echo successful
else
echo not successful >> /tmp/make_net_backup.log && mount -a
exit
fi
Is the syntax shown above correct?

Ubuntu Networking :: Use Local IP Only On Local Network?

May 25, 2010

I've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.

However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.

Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?

Networking :: 3 Nics - Connect To Internet - Share To Local Net - And Connect To Local Net - Not Working

Sep 15, 2009

I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.

It is running Ubuntu server 8.10

The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.

My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.

I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.

Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.

Ubuntu :: Custom Live CD - Run Without Changing System Link

2.) On boot run an existing .sh script

I would like to make a thumbdrive with a live cd version that will auto run to desktop and execute the .sh script. I am looking for pointers on accomplishing this. I have found ways to get the live cd to run on USB, but it still involves clicking the "run without changing your system link" and I cannot figure out how to run the script on start up.

General :: Link Home Directory To Different File-system?

Aug 27, 2009

I'm looking for some advice about how to implement the following functionality in my pet project.

There are two users on my system, user1 and user2. When user1 logs in he can do what he wants etc.. when user2 logs in I want to somehow link the entire file system to another place. In more detail when user2 logs in and does something like ls ~, he should see contents of /home/user1/extra/home/user2/ instead of /home/user2/
and when user2 does ls /usr/bin he should see contents of /home/user1/extra/usr/bin/

Is there a simple way to do this kind of operation. I have looked up the ln command, but I am a little unsure about how to show a completely different file structure to a particular user.

I did play around with ln and found that you can make "soft links" to directories. The problem being how can I link the user2 home directory /home/user2 to something like /home/user1/buffer/home/user2 . can I use something like ln -s /home/user1/buffer/home/user2 /home/user2 .. I guess not. I didn't want to try it as I wasn't sure so as to not hose my system.

Programming :: Link Directories - Symlink Not Updated / Hard Link Not Supported?

Sep 6, 2010

In the ordering of files I keep I need links to directories. Sometimes I even need to move directories to new locations. I have tried using symlinks, but they become dead when I move the directory they point to. I have tried hard links, but I haven't found any Linux file system that would support hard linked directories. How can I achieve that a complex structure of directories (currently with symlinks for directories and hard links for files) keep symlinks live when directories are moved?

- is there any utility that updates symlinks when a directory is moved?

- is there any Linux filesystem that supports hard linked directories?

- is there any good Linux interface to the new NTFS (the only file system I know to support automatically updating directory links, called directory junctions)?
