Ubuntu Servers :: TimeMachine Failed Since A Couple Of Days?
Jul 29, 2010
My macbook is backed up using timemachine on a samba drive. I used this hack for months [URL]his tuto is based on Netatalk, but works perfectly with Samba (or used to), as described in many others blogs.A couple of days ago, I had a strange message from timemachine, like the backup should be reconstructed to improve the security. The sparsebundle has been deleted, and timemachine try to create a new one now. This step failsI tried to create manually a new sparsebundle, using the tuto. It does not work.I have a backup of the sparsebundle ... I can navigate into it ("enter timemachine"), but I cannot backup anymore.

I upgraded to Mythbuntu 9.10 from 8.10 and things went fairly well. No major problems during the upgrade. The system is just a mythbackend server. The only things that access it are for myth and for the smb mounts for mythtv. Every couple days, the system stops responding to network traffic. No myth connection, no smb, no pings even. All I have to do is wiggle the mouse on the system and everything comes back up instantly. I noticed that after it comes back up, the time is off by hours.

My Suse 11 computer has been crashing; randomly once every couple
of days. This computer mostly sits unattended downloading torrents,
except when I'm browsing torrent sites or moving files.
Typically, the mouse, keyboard and screen freezes, though some
processes may (or may not) still be running in the background.
It seems to crash more often when there is intensive harddrive
usage. A fiend tested the hard drives. And the drives formatted
and OS reinstalled without fixing it.
1) What software can I use to test the ram?
2) I know my powersupply is marginal (and consumption highest
using the harddrives), could low voltage cause this?
3) What else should I look for/test.

I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing.
Whenever I go to sleep and there's no activity on my servers (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online!
I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active.

I am running Ubuntu 10.10 and have 5 shares that I have setup for Samba (assume names of share1, ..., share5). I find that shares(2,3,4) are accessible from my MS Windows system, but the share1 and share5 are listed but Windows gives an error accessing them that I may not have permissions.I have reviewed the sharesve the same owner, group, and permissions.Is this a known Samba bug or configuration issue? I have gone through the smb.conf file multiple times as well as examining the directories and do not see what the issue might be.

I am in the process of setting up a couple of virtual servers in a cloud environment. I am currently working on my application server (Server 1) and am stuck on the creation of my ruleset for this server.
I need to allow SSH, FTP, HTTP, HTTPS, and PING on this server. This server will also need to be able to talk with a couple of database servers as well as a memcache server (all internally within my cloud environment)
I have been reading on iptables, since I have never messed with them before, and have come up with the ruleset I will paste below. I have taken other steps to secure my server...changing ssh port, not allowing root to login via ssh without logging in as a user, turning off unnecessary daemons, editing my hosts allow/deny files, just to name a few.
I am a newbie to iptables, so I would love a bit of helpful advice, criticism, and even a good explanation why I should add or remove or edit something. I really want to know the how AND the why!

I've installed the latest cvs for ubuntu 10/04 and read a couple of how to on the web. I have environment set for CVSROOT, EDIT and CVSEDIT. It made me a ~/cvs/CVSROOT and I ran" cvs import mon Ian_C START" in my ~/cstuff directory and that has created ~/cvs/mon with my main.c file. These tutorials do not tell me which main.c file I should edit or how to edit. Should I edit ~/cvs/mon/main.c or ~/cstuff/main.c, should I just gedit it then do a few cvs commands to generate the diffs or whatever?

After in-place upgrade from 9.10 to 10.04, the message
Code:
Unmount of /dev/nbd0 failed
appears on the console at shutdown, with a warning that data may be lost, and followed by a 10 second countdown, after which shutdown continues normally.
Syslog shows this one line at each boot:
Code:
Oct 23 10:04:16 m2a74am kernel: [ 1.203334] nbd: registered device at major 43
Nothing gets mounted explicitly at /dev/nbd0, so I am puzzled about the error message on shutdown.

I am trying to update my server, but it won't do it. It tries to connect, but says "Waiting for headers". If i try to install other packages it says "Connection failed". Apparently it has Internet connection since my server shares Internet connection with other machines.

i recently decided to try and run a couple of games through wine, however trying to install two of them through wine, after putting in the second cd in the installer, the system will not recognise/mount the cd at all in the filesystem. it will instantly recognise the cd after i quit the installer for both of the games, so i guess that running the wine setup is interfering with ubuntu's ability to read or mount a cd. since it has happened on two separate occasions and has worked on windows, there must be something happening on my system that is preventing it. so my question is has anybody else experienced this or think that they know what might be causing the problems?

As the title says, I have a failed RAID5 hard drive. What's the easiest way I can go by replacing it? I've seen many ways to do this, but I would like to know what other people are saying about this, and see how you would do it.
P.S. This is the one I found. [URL]

I recently set up exim so that I could test emails sent from my php sites. I have now been getting daily emails that either report errors from cron jobs or report a failure to send emails to root@cory-laptop or cory@cory-laptop about cron errors.I first of all don't want mail sent to the above addresses, because they are obviously not actual email addresses. Second, I'd really prefer not to get emails when an email failed to send to these addresses.

I've followed [URL] to set up vpns with some external networks. So far it worked like a charm on two of them. But when trying to connect to the third one I instantly get bumped off.

I've looked all over the internet but sollutions like adding mmpe-stateful to options.pptp doesn't work. Is this a problem with the client or with the server? Because the server is configured just like the other two and they work as intended. Seemed to be a problem on the firewall.

I recently ran into the following problem when trying to ssh into my Ubuntu 11.04 server:
>> ssh user@site.com
PTY allocation request failed on channel 0
I don't know for sure, but I think this happened after one of the latest Ubuntu updates I installed. In case it's of relevance, I'm remoting in from Terminal (Mac OS X 10.7 - Lion). Edit: The problem seems to be with Lion..

In a small network (with <5 PCs) what is the best way to manage users and groups? When I create a new user, Ubuntu automatically assigned a UID unless I specify otherwise. If I were to mount shared drives between PCs (or between a client machine and a server) I'm wondering how it handles different UIDs/GIDs associated with files (usernames almost always match across system but UIDs/GIDs do not)? Or is the best solution to just assign matching UID and GID on every machine when they are created? Or is this just magically handled via the matching usernames? I know there are heavier options but this has come up a number of times in small setups 2-5 machines at most.

I'm looking for advice on a good backup solution. I have a couple Ubuntu machines running at home, and I'd like them to backup to a NAS, which supports CIFS and NFS. Rsync might work, but I don't want to have to write a script myself, or figure out how to accomplish a staggered history of backups. The default "simple backup" sbackup doesn't work for me. I've not been able to unroll those gigantic .tgz files it makes. The restore GUI doesn't seem to work at all; it claims it can't find any backups.
My confidence is shot. I tried Back in Time. I set the GUI control panel to backup every day. It didn't back up every day. Maybe I'm getting it wrong. But, my confidence is shot. I looked at Amanda and Bacula. Both seem to require that your backup server run special software; I don't want to hack into my NAS to do that. Both also seem to require 10 hours of study to figure out just how to install them.

I've just installed Ubuntu 10.04 on a AMD processor with a nvidia graphic card in dual boot with windows xp. First the live-cd was already freezing after a couple of minutes so I had to install Ubuntu with the alternate cd. Now it freezes whatever I do after 2 or 3 minutes. I had exactly the same problem with the 6.04 version but I had only to remove powernowd from /etc/init.d/ to make it perfectly working. But unfortunately this file seems not to be there in this version.

I am unsure if this is a hardware problem or a linux problem. My machine is only 3 months old so it is not the fan. I didn't have problems until recently, and after the latest kernel update it got worse - having to restart more frequently.
I do not experience the fan turning off in windows. I use thinkfan when I have to but it isn't a very good program for an every day basis. The fact I can force start the fan with thinkfan when it turns off leads me to believe it is a kernel issue.

First of all I'd like to say me and my family and friends who ive converted to Ubuntu users have had trouble with natty from the start (needing to mount the drive manually from the terminal after the upgrade being one of the problems) but there are two problems I was curious if anyone else had and fixed. The first problem is an app called "DeVeDe" which is used to convert video files into isos, it appears to work fine until the end when it errors and says I may be out of disk space. My work around is to take the MPG file it converted (which didn't seem to be affected by the error) and convert it using bombono into the ISO. Bombono gives me a similar error if I try to use it from the beginning, so devede does the first half without retiring and bombono does the second half, both program's world perfectly before upgrading to natty and I've tried changing settings and reinistalling but nothing helps. My second problem is with my nvidia drivers, they seem to work fine when I'm using my monitor but when I try to use my 47" LED vision as a monitor it says its detecting it as a CRT and only lets m do 1024x768 as my Max resolution. I know some people will say I should be posting in recede and nvidias forums but thee bugs aren't there fault, as both things world perfect before I upgraded to natty

I've just noticed a small problem I am having with my company file server. When making backups to an external NTFS drive weekly I have noticed that the file names with thai characters are not getting backed up. I receive the below error:
rsync: recv_generator: failed to stat (to the file name...)
Invalid or incomplete multibyte or wide character (84)
There are thousands of files on the server that contain thai characters in there names so how do I get around this problem so it will back up all files and not just the English character ones. I read somewhere that each file would need to be converted to a different character set but this would take years as there are so many files.

mdadm: looking for devices for /dev/md0
mdadm: no recogniseable superblock on /dev/sde4
