I can't read the boot log In Ubuntu Server 10.10. I did this:
Code:
BOOTLOGD_ENABLE=yes in /etc/default/bootlogd
But the file /var/log/boot is empty:
Code:
cat /var/log/boot
(Nothing has been logged yet.)
I have an interesting issue Ubuntu Server 8.04, The server has been running for quite a while (not designed or put together by me) but recently it has started segfualting and now will not boot apart from in read-only mode. I see the following errors in dmesg.
[Code]....
does anybody know if there is some web tool which allow the end user to read the server log ? I am a system administrator in my company and i would need to share the server log information to the developer team without allowing them to access to the server.I was thinking to some web applications .. i would try phpLogCon but unfortunately it reads only syslog . I need to share some application logs (php or java web application).

I went away for the week, and not until the day I got back I lost power while out, and my computer rebooted after the power outage to Mac osx, which it's supposed to do as I'm using a Mac Pro and have a regular version of OSX 10.5 on there and my ubuntu server. I restart my computer and I get a few errors and my raid5(3 1tb drives) doesn't mount and says read only for everything else. I finally found a way to remount that raid which while in root I could create new folders and move folders, but only on that raid. I wasn't able to do anything with my boot drive. The weird part is, that now I can't ssh into the server and webmin won't even load. I'm still relatively new(little over a year, but honestly, not much has gone wrong to need to troubleshoot) to ubuntu server, so I'm not that best at troubleshooting it. I won't be home till later tonight, but any tips/tricks/ideas I can try when I get home would be great, or if you need any info, I can get it to you.

2. CPU integrated Intel Atom D410
3. 2 Gb of RAM
4. Network Card D-Link DGE-528T 10/100/1000 Mbit/s
5. OS Ubuntu Server 10.04.2 (All installed packages are up to date)
Storage build under LVM based on:

2. Hitachi SATA 2000Gb Deskstar 7K3000 - 2 Tb, 7200/64 Mb.
So found one issue: When torrent upload speed reaches peak speed (160-200 Kbytes/s) huge read slowdown happens. Server becomes almost unreachable... It allows to connect via putty but it takes a lot of time.
Tested top stats during those lags (Deluge, Transmission) - 10-15% CPU usage.
So I think the problem is in LVM and not in CPU.
How is it possible to find weak place in system to avoid those lags... Cause if torrent is seeding it's impossible to watch movies through network form that server.

I have a 9.04 64bit Ubuntu server that I use for a home file server and for downloading duties, every few days the root filesystem gets remounted as read only, usually requiring a reboot and fsck to get everything running again.

My server is not accessible any longer locally (192.168.0.2). If I attach a keyboard and login (I have done one pass of recovery from the Ubuntu live CD which helped) and check the IP address it seems to be set. However looking at the syslog file there is a line which says ext3-fs: info: recovery required on read only files system.
Is there a more extensive ext3 recovery facility I can use bearing in mind I will not (?) be able to install it?

I am using Fedora 14 64 bit with two 1T drives. There is a Raid 1 for the important information and I use a Raid 0 for cached files that can be generated on the fly. Yesterday my Raid 0 went into read only mode.
Here are a couple of tests:
What caused the Raid 0 drive from /dev/md1 to get removed? Is there a way to get it back to active sync?

On an Apache2 server someone else setup, I have a folder with drwx--x--x permission and the php file can still write in the folder. But on my own setup, I need to set the same folder to drwx--x-wx. Inside the folder, I have a index.php that runs just by setting rwx--x--x but on my own setup, I need to allow read permission for others/group before it can run: rwxr-xr-x (or else I get a blank page). I tried changing the folder and files to root but it's the same.

I have a weird problem here with a 9.04 server. We have a raid 5 disk formatted in EXT4 which remounted automatically when we accessed to the lost+found folder which is in the root of that disk.
I tried to delete it but I can't. It's a bit annoying because I have to prevent all users and backups to access to that folder.
figure out this error?

How would I set the folders as read only but not the contents, so that way remote users can read/write to the folder but can't delete or rename the folder itself? Also, if I restart the Linux box it will cease to show on the Windows Network unless I delete the Samba share and remake.

View 5 Replies View RelatedI have a linux server running ubuntu 10.04, kernel Linux server 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux. A few months ago I installed ubuntu to a USB flash drive (Patriot 16GB) and was able to successfully boot off it, and everything was running fine. Then all of a sudden I noticed that the root filesystem was read-only, and I saw errors in the kernel log:
[ 725.528732] sd 2:0:0:0: [sdc] Unhandled sense code

I tried reading the drive to see if there was a problem with the drive itself:
root@server:~# dd if=/dev/sdc of=/dev/null

1966184+0 records out

But the strange thing is that if I put that usb stick in a different linux server, I'm able to read the whole drive. If I run fsck, it fixes a bunch of errors, but when I put the drive back in the original PC it will work for a while and then fail with the same type of I/O error (not at the same offset though). I had this same problem occur on a different USB stick in the same server, I had thought it was bad media so I replaced it, but now the same problem is happening on a different usb drive. I have backups of the data, but I would really like to figure out what is causing this before I throw in the towel and buy a new PC.
So I upgraded my hard drive and went with a clean Lucid install. But now I want to get files off my old drive. When I re-hooked it back up (now 2 drives in the system), ubuntu refuses to boot. It kind of boots then just hangs. Never gets to the desktop, and the HD lite on my case is constantly flickering (what could it be doing??)
I have it set up correctly in my BIOS so that the new drive is the boot drive, not the old one. The only difference is that the new drive is sata and the old drive is old school pata (ide). I even tried pulling out the old pata drive and hooking it up to a USB adapter I have. Looking at it in the Disk Manager, it shows it as unformatted, and old faithful GParted doesn't even see it!
Now get this: I pulled out my new sata and put back in the old ide drive and guess what, now it wont boot! Grub (probably MBR) is screwed up also! Any ideas how I can read the data from that old drive? Ether by getting my new lucid install to boot with the old drive as a slave in the system, or by hooking it up externally using USB?
I have a few ubuntu servers which have samba shares on the network and for the most part have had little trouble with them. Recently we purchased a few iMac's for one of our deptartments and, while we're able to access the shares, all the files on them are read-only and we are unable to delete/modify files using the iMacs. This is not an issue with any of our windows machines (W2K, WinXP, Vista).
View 2 Replies View RelatedI'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I am trying to setup my webserver and I am trying to make a website to run under suexec but somehow I cannot start my apache it directly fails and SELinux is giving me errors and don't really know what to do with it, it is giving me some command to type but not sure if this will make my server less secure. The SELinux error is as follow:
Code:
Summary:
SELinux prevented httpd reading and writing access to http files.
Detailed Description:
SELinux prevented httpd reading and writing access to http files. Ordinarily httpd is allowed full access to all files labeled with http file context. This machine has a tightened security policy with the httpd_unified turned off, this requires explicit labeling of all files. If a file is a cgi script it needs to be labeled with httpd_TYPE_script_exec_t in order to be executed. If it is read-only content, it needs to be labeled httpd_TYPE_content_t, it is writable content. it needs to be labeled httpd_TYPE_script_rw_t or httpd_TYPE_script_ra_t. You can use the chcon command to change these contexts. Please refer to the man page "man httpd_selinux" or FAQ [URL] "TYPE" refers to one of "sys", "user" or "staff" or potentially other script types.
Allowing Access:
Changing the "httpd_unified" boolean to true will allow this access: "setsebool
-P httpd_unified=1"
Fix Command:
setsebool -P httpd_unified=1
I will write down how I did setup my server so maybe you can see a mistake I did. First I changed my Apache httpd.conf I added the following to it:
Code:
NameVirtualHost 192.168.1.2:80
<VirtualHost 192.168.1.2:80>
ServerName localhost
DocumentRoot /var/www/html
DirectoryIndex index.html index.html index.shtml index.php
</VirtualHost>
<VirtualHost 192.168.1.2:80>
SuexecUserGroup ulyaoth ulyaoth
ServerAdmin webmaster@ulyaoth.org
ServerName test.ulyaoth.org
DocumentRoot /var/www/ulyaoth/www/html
ErrorLog /var/www/ulyaoth/logs/error_log
CustomLog /var/www/ulyaoth/logs/access_log common
DirectoryIndex index.html index.htm index.shtml index.php
ScriptAlias /cgi-bin/ /var/www/ulyaoth/www/cgi-bin/
<Directory /var/www/ulyaoth/www/cgi-bin/>
AllowOverride none
Order allow,deny
Allow from all
Options +execCGI
AddHandler cgi-script .cgi .pl
</Directory>
</VirtualHost>
Then I created the username "ulyaoth" with the group "ulyaoth" as I specified with my suexec, then I created all the directories as specified in my httpd.conf and "chown ulyaoth:ulyaoth (dirname)" them to the right group and username.

I am editing this post to save people time and effort. This is one of those "Pilot Error" issues or faulty readout issue, not sure which. It turns out that when I saved a document in PDF format to my NTFS Drive (the one I want to share between Windows XP and Ubuntu 10) the .PDF file extension was missing.
1. Ubuntu identified the files as a PDF document (even though the file extension was not there)
2. When trying to access it by double clicking it, the message was "Unable to open document, Permission Denied"
The problem was not permissions, and it was not a PDF file according to the default Document Viewer, but it WAS a PDF file according to the directory listing. The permissions message really had nothing to do with the problem, and identifying the file as a PDF document when it didn't have an extension, was another problem. What SHOULD have happened is a file without an extension should not be identified as a PDF file or If Ubuntu says it's a PDF file, and I double click it, why is the message "Permission Denied" ?? How about "No File Extension" or something like that?
Read the following if you want to see what my problem WAS before I just appended ,PDF to the filename, and now it works fine. On the positive side, installing XP first, then setting aside a large chunk of space for a shared NTFS drive, and THEN installing Ubuntu in the free space works fine. I installed a new 320 GB drive on laptop. Installed Win XP in 32 GB Set aside 250 GB for another Windows partition using MANAGE and formatted D: as an NTFS drive Then successfully Installed ubuntu 10 into remaining unused space. Problem: Ubuntu cannot access files from D: (NTFS Windows) partition. but it can WRITE files without problems, and create directories, just not read them. Have set properties of the Windows drive to shared, still nada. Any trick I'm missing? If I plug in an external USB drive, Ubuntu can read/write to it easily, it just can't read from the 250 GB partition formatted in Windows XP that I wanted to share between operating systems.
I've been reading various tutorials of the boot process but still am not clear. I don't care about grub stage 1 and 1.5 at the starting point of when the root filesystem is loaded into VFS(Virtualfilesystem), who is loading it, and from that point on. 1) Does grub load the root filesystem(read only) into VFS?2) Does the kernel load the root filesystem(read only) into VFS?3) Does INIT load the root filesystem(read only) into VFS?after this is concluded....Does INIT or the Kernel create the real root filesystem(rw)...right before the pivot.root

Windows is on SDA4 which is the last partition of the drive, it is mounted at sda4/windows using ntfs. I then loaded Mint 8 gnome on the 2nd partition sda2 using ext3 mounted at /, sda1 is my Linux swap, and sda3 is mounted at /home using ext3. While installing I selected to mount Linux ext3 at /
When I choose to load winXP from the grub boot loader I get dev/sda4 no such device 10CDR36778638F73. Also when I try to unmount from disk utility I get the following error: Error unmounting: umount exited with exit code 1: helper failed with: umount: only root can unmount UUID=10CDF36778638F73 from /windows Seemslike I need to rename the drive but it won't let me in disk utility.
My Problem is that within PYSDM (storage device manager) I uncheck Mount file system (sda4/windows) as a read only but it will not stay unchecked. I have unchecked it hit unmount and mount and it still is checked to mount as a read only. This is the code in options for sda4 in PYSDM (storage device manager) nls=utf8,umask=007,gid=46
I tend to get constant crashes when using internet browsers ( Google Chrome and Firefox ) basically the application hangs not moving in any way, then eventually completely freezes up, the system then locks up and finally crashes.
Upon system re-start I get "Read Error" at boot ( No further information, it literally just says "Read Error" ).
It is sometimes fixed by going into the BIOS and select "Hold on No Error".
I tried installing OpenBios to see if using different BIOS firmware would resolve the issue, but the OpenBios install failed ....so no dice there either.
I am trying to work out if it is a hard drive problem or if it is purely a problem with Fedora.
It was working fine for a couple of months and when it does boot up ... the system works fine, ( Until another crash ).
It seems like the internet browsers crash the system and then the system crashes and can then no longer remember how to boot up.
what this could be that could be software based....if not it looks like I will need a new hard-drive.
