  • Windows 2008 R2 CA and auto-enrollment: how to get rid of >100,000 issued certificates?

    - by HopelessN00b
    The basic problem I'm having is that I have 100,000 useless machine certificates cluttering up my CA, and I'd like to delete them, without deleting all certs, or time jumping the server ahead, and invalidating some of the useful certs on there. This came about as a result of accepting a couple defaults with our Enterprise Root CA (2008 R2) and using a GPO to auto-enroll client machines for certificates to allow 802.1x authentication to our corporate wireless network. Turns out that the default Computer (Machine) Certificate Template will happily allow machines to re-enroll instead of directing them to use the certificate they already have. This is creating a number of problems for the guy (me) who was hoping to use the Certificate Authority as more than a log of every time a workstation's been rebooted. (The scroll bar on the side is lying, if you drag it to the bottom, the screen pauses and loads the next few dozen certs.) Does anyone know how to DELETE 100,000 or so time-valid, existing certificates from a Windows Server 2008R2 CA? When I go to delete a certificate now, now, I get an error that it cannot be delete because it's still valid. So, ideally, some way to temporarily bypass that error, as Mark Henderson's provided a way to delete the certificates with a script once that hurdle is cleared. (Revoking them is not an option, as that just moves them to Revoked Certificates, which we need to be able to view, and they can't be deleted from the revoked "folder" either.) Update: I tried the site @MarkHenderson linked, which is promising, and offers much better certificate manageability, buts still doesn't quite get there. The rub in my case seems to be that the certificates are still "time-valid," (not yet expired) so the CA doesn't want to let them be deleted from existence, and this applies to revoked certs as well, so revoking them all and then deleting them won't work either. I've also found this technet blog with my Google-Fu, but unfortunately, they seemed to only have to delete a very large number of certificate requests, not actual certificates. Finally, for now, time jumping the CA forward so the certificates I want to get rid of expire, and therefore can be deleted with the tools at the site Mark linked is not a great option, as would expire a number of valid certificates we use that have to be manually issued. So it's a better option than rebuilding the CA, but not a great one.

  • Disable .htaccess from apache allowoverride none, still reads .htaccess files

When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and # "force-response-1.0" for this. BrowserMatch "MSIE [2-6]" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 # MSIE 7 and newer should be able to use keepalive BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown </VirtualHost> </IfModule> /etc/apache2/sites-available/default <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> Alias /delboy /usr/share/phpmyadmin <Directory /usr/share/phpmyadmin> # Restrict phpmyadmin access Order Deny,Allow Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path.

  • Memcached Debuging/Server Logs Monitor the Memcached Servers?

    - by user1179459
    I have chat engine which is based on the Memcached variables, putting them into arrays and reading them in other end via jquery, which works fine 95% of the times, however when the server load is high memcached (presume its the memcached) the crash and browser gets stucks up. I dont think its jquery issue since this only happens when the server load is very high. I need a way to monitor the memcached servers or somehow write a log file into where the fails/errors comes in... Any idea on how i can do this ? or any idea why memcached servers fails ? I run the memcached as follows $GLOBALS['MemCached'] = FALSE; $GLOBALS['MemCached'] = new Memcache; $GLOBALS['MemCached']->pconnect('localhost', 11211); My memcached config is as follows #! /bin/sh # # chkconfig: - 55 45 # description: The memcached daemon is a network memory cache service. # processname: memcached # config: /etc/sysconfig/memcached # pidfile: /var/run/memcached/memcached.pid # Standard LSB functions #. /lib/lsb/init-functions # Source function library. . /etc/init.d/functions PORT=11211 USER=memcached MAXCONN=1024 CACHESIZE=128 OPTIONS="" if [ -f /etc/sysconfig/memcached ];then . /etc/sysconfig/memcached fi # Check that networking is up. . /etc/sysconfig/network if [ "$NETWORKING" = "no" ] then exit 0 fi RETVAL=0 prog="memcached" pidfile=${PIDFILE-/var/run/memcached/memcached.pid} lockfile=${LOCKFILE-/var/lock/subsys/memcached} start () { echo -n $"Starting $prog: " # Ensure that /var/run/memcached has proper permissions if [ "`stat -c %U /var/run/memcached`" != "$USER" ]; then chown $USER /var/run/memcached fi daemon --pidfile ${pidfile} memcached -d -p $PORT -u $USER -m $CACHESIZE -c $MAXCONN -P ${pidfile} $OPTIONS RETVAL=$? echo [ $RETVAL -eq 0 ] && touch ${lockfile} } stop () { echo -n $"Stopping $prog: " killproc -p ${pidfile} /usr/bin/memcached RETVAL=$? echo if [ $RETVAL -eq 0 ] ; then rm -f ${lockfile} ${pidfile} fi } restart () { stop start } # See how we were called. case "$1" in start) start ;; stop) stop ;; status) status -p ${pidfile} memcached RETVAL=$? ;; restart|reload|force-reload) restart ;; condrestart|try-restart) [ -f ${lockfile} ] && restart || : ;; *) echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart|try-restart}" RETVAL=2 ;; esac exit $RETVAL

  • My server freezes within a few hours of logging out. Staying logged in keeps the server running

    - by HappyEngineer
    I have an Ubuntu Godaddy server I use to host mail and webapps. It started having problems a couple months ago. It would lock up and stop responding to anything. I couldn't ssh into it, so I'd have godaddy power cycle the server. I have never seen anything that looked suspicious in the var logs (although I'm no expert at reading them). An fsck turned up no problems. Godaddy replaced the ram, but found no hardware problems. I started logging the output from "top" to a log file and found that even that stops running when the server freezes. Now, here is the crazy part: It got so bad that it would actually go down every few hours, but then it stopped going down. I eventually realized I had left an ssh terminal logged into the machine running top. This seemed unlikely to be a reason, but after the server was up with no problems for a full week (remember, it had been going down after just a few hours), I disconnected from the ssh session. Lo and behold, within a few hours the server froze again! I had them power cycle again and then left another ssh session open with top. It has been going without problems for 8 days now. I told others about this and they hardly believe me. I simply can't imagine what is going on. I don't know what else to try other than to just get a new server and reinstall everything. Does anyone have any ideas about what I can look for to determine what the cause is? Is it possible there's some sort of exploit on the server which only runs if everyone is logged out of the system? EDIT: The power management gone haywire sounds plausible, so I've modified the /boot/grub/menu.lst to boot with acpi=off and apm=off. It appears to have prevented kacpid and kacpid_notify from being in the process list, so I assume I did that right. I've disconnected all my sessions from the server. I'll check later tonight to see if it's still up. If it goes down then I'll try the pinging process idea. EDIT: It went down again. It lasted about a day. I've had them reboot, so now I'll try running "nohup ping -i 5 google.com &" and then disconnect. If it goes down again I'll come back. Hopefully someone will have some more ideas.

  • Permissions problems with Apache / SVN

    - by Fred Wuerges
    I am installed a SVN server (v1.6) on a VPS contracted with CentOS 5, Apache 2.2 with WHM panel. I installed and configured all necessary modules and am able to create and access repositories via my web browser normally. The problem: I can not commit or import anything, always return permission errors: First error: Can not open file '/var/www/svn/test/db/txn-current-lock': Permission denied After fix the previous error: Can't open '/var/www/svn/test/db/tempfile.tmp': Permission denied And other... (and happends many others) Can't open file '/var/www/svn/test/db/txn-protorevs/0-1m.rev': Permission denied I've read and executed permissions on numerous tutorials regarding this errors, all without success. I've defined the owner as apache or nobody and different permissions for folders and files. I'm using TortoiseSVN to connect to the server.

  • Is the master database backup crucial for restoring MS SQL server in the event where you have to res

    - by Imagineer
    I have been advise by Commvault partner support to turn off the backup of the master database as the backup failed due to the log file being lock. The following is the advise given: "The message is caused by Commvault’s inability to backup the master database’s transaction log. If this is happening intermittently its possible that something is locking the transaction log, preventing SQL iData agent from accessing the log. Typically the master database is just a template and is not used by any applications (applications that do require the use of an SQL database create their own) so there should be no harm in preventing it from being backed up You can do this by nominating NOT to back it up in the primary copy for the SQL data agent" The following is the error that I get. sqlxx SQL Server/ SQLxx N/A/ System DBs 19856* (CWE) Transaction Log N/A 01/08/2010 19:00:16 (01/08/2010 19:00:18 ) 01/08/2010 19:03:15 (01/08/2010 19:03:14 ) 1.44 MB 0:01:11 0.071 2 0 1 ITD014L2 Failure Reason: • ERROR CODE [30:325]: Error encountered during backup.

  • VMWare tools not installing with an error

    - by JDS
    VMWare tools not installing on Ubuntu 12.04. I'm using Chef to manage the installation, but the Apt commands fail if run manually. I'm using the VMWare tool Debian repo.

However, I've tryed removing and purging and can't seem to "trick" VMWare tools into thinking the packages are gone. Apt thinks they are gone. Is there some service/file/cache/lock left that VMWare tools sees that makes it think that VMWare tools are still installed? I've googled and googled but there is no answer to this question with my particular circumstances on the interwebs. VMWare's documentation of this error is minimal.

  • How to properly shutdown a Linux VMware Server Host

    - by Mikee
    Hi Everybody: In our lab, we have a server running Ubuntu Linux 8.04.4 x64, with VMware Server 2.1 hosting 4 VM's. I have a major concern with regards to shutting down the host server. Mostly, how do I ensure that the guest VM's are being shut down safely? In the VMware web interface console, I have enabled: "Allow virtual machines to start and stop automatically with the system" I enabled the Default Startup Delay for 15 seconds along with the "Start next VM immediately if the VMware Tools start" option checked I enabled the Default Shutdown Delay with a 60 second shutdown delay and a Shutdown Action of "Shut Down Guest" All VM's have the VMware Tools installed and properly working. All VM's are moved up into the "Specified Order" section of "Startup Order", thus when powering the server back on, all those VM's should start up again in that specified order. When I went to shut down the server, I used the shutdown -h now command. Based on the settings I entered above, I was expecting a 4 minute shutdown, as there is an option to delay the shutdown of each VM by 60 seconds. However, that is not what happened. Instead, the server shutdown in under a minute. When I powered the server back on, only 2 VM's properly loaded. The other 2 showed the following error: "Power on Virtual Machine" failed to complete If these problems problems persist, please contact your system administrator. Details: Cannot open the disk '[location to .vmdk]' or one of the snapshot disks it depends on. Reason: Failed to lock the file. Obviously, if this error occured, then it is clear to me that the VM's were not properly shutdown, or the server powered off before the VM's were completely shutdown. I have fixed the above error by deleting the .lck files in the respective VM directories. How would I know if the VM's were properly shut down? I checked the VMware-server logs, but they only seem to display the logs of when the vmware-mgmt service is running in the current session. I'm mostly running Linux VM's, so is there an easy way to know whether or not a server was properly shut down in Linux? Thank you all for the help!

  • Starting/Stopping Custom PHP Chat Server Linux Service (CentOS)

    - by chad
    I have been trying all night to get this service working properly. I created this script from a template and am very new to bash coding. I wrote a fully functioning chat server in php which runs endlessly, but now want to make it a dedicated service. I want to do this so that it starts on server boot and boots back up if possible when there are any down-times with the server. The issue is that I need this thing to run in a detached screen so that I can monitor packet data or send server commands via SSH when need-be. The main problem that i'm having is that it needs to have its own PID when it starts so that I can stop/restart it when needed. I am the type who grinds on coding until I figure it out, but this is so new to me that it seems the learning curve here is very steep and frustrating. Below is my code if anybody can please help me with this one, i've gotten so tired I can't even concentrate any more :( #!/bin/sh # # chatserver # # chkconfig: 345 20 90 # description: chatServer Linux Service Daemon \ # for general server handling ### BEGIN INIT INFO # Provides: chatserver # Required-Start: $local_fs $network $named $syslog # Required-Stop: $local_fs $syslog # Default-Start: 3 4 5 # Default-Stop: 0 1 2 6 # Short-Description: This service maintains the chatServer # Description: chatServer Linux Service Daemon # for general server handling ### END INIT INFO # Source function library. . /etc/rc.d/init.d/functions exec="screen php -q /var/www/html/chatServer.php" prog="chatserver" config="/etc/sysconfig/$prog" pidfile="/var/run/chatserver.pid" [ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$prog lockfile=/var/lock/subsys/$prog start() { #$exec || exit 5 echo -n $"Starting $prog: " daemon $exec --name=$exec --pidfile=$pidfile retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval } stop() { echo -n $"Stopping $prog: " killproc -p $pidfile rm -f $pidfile retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval } restart() { stop start } reload() { restart } force_reload() { restart } rh_status() { # run checks to determine if the service is running or use generic status status $prog } rh_status_q() { rh_status >/dev/null 2>&1 } case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart) $1 ;; reload) rh_status_q || exit 7 $1 ;; force-reload) force_reload ;; status) rh_status ;; condrestart|try-restart) rh_status_q || exit 0 restart ;; *) echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}" exit 2 esac exit $?

In this url http://bugs.centos.org/view.php?id=4515 a lot o people report similar problems, except the fact that they are not related to httpd like mine. According to one member, one solution would be to add "elevator=noop " to /etc/grub.conf like in this example: title CentOS (2.6.18-238.12.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-238.12.1.el5xen ro root=/dev/VolGroup00/LogVol00 elevator=noop initrd /initrd-2.6.18-238.12.1.el5xen.img Would this really solve the problem? My disk are working in RAID. Can this cause some problem to my server? Is there any other solution?

  • Disable Acer eRecovery system

    - by Joel Coehoorn
    The meat of this question is that I'm looking for a way to either require a password before using a recovery partition or "break" the recovery partition (specifically, Acer eRecovery) in a way that I can later "unbreak" only by booting normally into windows first. Here's the full details: I have a set of new Acer Veriton n260g machines in a computer lab. A lot work went into setting up this lab to work well - for example, Office 2007 and other programs needed by the students were installed, all windows updates are applied, and a default desktop is setup. All in all it's several hours work to fully set up one machine. Unfortunately, I don't currently have the ability to easily image these machines, and even if I did I would want to avoid downtime even while an image is restored. Therefore, I've taken steps to lock them down — namely DeepFreeze and a bios password to prevent booting from anywhere but the frozen hard drive. DeepFreeze is an amazing product — as long as you boot from the frozen hard drive, there is no way to actually make permanent changes to that hard drive. Anything you do is wiped after the machine restarts. It lets me give students the leeway to do what they want on lab computers without worrying about them breaking something. The problem is that even with the bios locked and set to only boot from the hard drive, these Acers still have a simple way to choose a different boot source: shut them down and put a paper click in a little hole at the top while you turn it on again. This puts them into the "Acer eRecovery" mode. This by itself is no big deal — you can still power cycle with no impact. But if you then click through the menu to reset the machine (we're now past the point of curiosity and on to intent) it will wipe the hard drive and restore it to the original state. Of course, a few students have already figured this out and reset a couple machines. That's unfortunate, but inevitable. I don't want to destroy the ability to do this entirely (which I could by repartitioning the drives to remove the recovery partition) but I would like a way to require a password first, or "break" the recovery system in a way that I can "unbreak" only if I first un-freeze the hard drive in DeepFreeze. Any ideas?

Also, I have tryed to setup mysql on independant Linux Server but kept getting errors. When, I found the solution. Wouldn't work, so I decided to try Windows. These is the questions, I have been asking and researching to debug this issue Is it because I am using Linux for magento and Windows for Database. I have had no luck in finding a reason why this wouldn't work There must be something, I am missing I also researched the difference between linux sql databases and windows sql databases but have not come to conclusion, if installing Mysql on windows would make a difference in syntax and coding. I have spent a lot of time looking into this and need some help with direction on how to complete my project. Any type of help would be appreciated.

  • How to make Shared Keys .ssh/authorized_keys and sudo work together?

    - by farinspace
    I've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like: $ sudo cd /root it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set) Also, ive disabled the users password using $ passwd -l user What am I missing? Somewhere my initial remarks are being misunderstood ... I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file. Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time). For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password. But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled. Edit: Ok I think I've got it (the solution): 1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this 2) I've adjusted the sudoers list visudo and added root ALL=(ALL) ALL dimas ALL=(ALL) NOPASSWD: ALL 3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user) The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user. NOTE The above works but is considered poor security. Any script that is able to access code as the "dimas" or "sherry" users will be able to execute sudo to gain root access. A bug in ssh that allows remote users to log in despite the settings, a remote code execution in something like firefox, or any other flaw that allows unwanted code to run as the user will now be able to run as root. Sudo should always require a password or you may as well log in as root instead of some other user.

  • How to unlock and remove a protected partition from Prestigio USB stick?

    - by mr.b
    Ok, so, I have one of those fancy schmancy devices, which is given to me by a frustrated friend of mine. Device is a Prestigio Leather 8GB, which identifies itself to Linux host as: Bus 001 Device 006: ID 1307:0165 Transcend Information, Inc. 2GB/4GB Flash Drive Kernel messages as USB device is plugged in: kernel: [ 2769.580042] usb 1-9: new high speed USB device using ehci_hcd and address 7 kernel: [ 2769.714782] scsi8 : usb-storage 1-9:1.0 kernel: [ 2770.713937] scsi 8:0:0:0: Direct-Access 8192MB flash drive 1.00 PQ: 0 ANSI: 2 kernel: [ 2770.714535] scsi 8:0:0:1: Direct-Access 8192MB flash drive 1.00 PQ: 0 ANSI: 2 kernel: [ 2770.715734] sd 8:0:0:0: Attached scsi generic sg3 type 0 kernel: [ 2770.716108] sd 8:0:0:1: Attached scsi generic sg4 type 0 kernel: [ 2770.722175] sd 8:0:0:0: [sdc] 962560 512-byte logical blocks: (492 MB/470 MiB) kernel: [ 2770.722657] sd 8:0:0:0: [sdc] Write Protect is on kernel: [ 2770.731078] sd 8:0:0:1: [sdd] 14012416 512-byte logical blocks: (7.17 GB/6.68 GiB) kernel: [ 2770.731215] sdc: kernel: [ 2770.738251] sd 8:0:0:1: [sdd] Write Protect is off kernel: [ 2770.880328] kernel: [ 2770.885876] sd 8:0:0:0: [sdc] Attached SCSI removable disk kernel: [ 2770.887442] sdd: unknown partition table kernel: [ 2771.049605] sd 8:0:0:1: [sdd] Attached SCSI removable disk So, symptoms are typical for U3-like devices: two separate devices inside of a single flash device. Windows sees it also as two identical usb devices, and mounts two separate drives to system, whereas first one presents itself as a CDROM device, holding a write-protected content, and second is a regular flash-disk partition, that "can" be written to. However, it seems like it's broken in some weird way, since it won't let me write anything to it, format it, nothing, but that's not the issue right now. Question: How can I unlock entire USB stick so it appears to system as a single, 8GB device which can be partitioned and used normally, without restrictions? Since it appeared to be an U3 device, I have tried standard utilities: both U3 Uninstaller by u3.com (found on SoftPedia), and opensource u3_tool from sourceforge (on both Windows and Linux). First utility failed to even detect USB stick as U3 device (simply stood idle while I re-plugged stick several times), while second tool failed with some obscure error about SCSI command unable to do something (I might be able to provide exact errors when I switch back to windows). u3_tool -i /dev/sg3 (Display device info) fails with u3_partition_info() failed: Device reported command failed: status 1 ...and every other option fails with same error, minus first part which states which command precisely has failed. So, apparently, this isn't a U3 device. Or, if it is, it doesn't behave like one. I read on a few occasions that this device protection is done by special command sent to device which tells it to lock itself, and so there should be an unlock command, that would set drive straight. Does anyone have any idea about what could I do to this device to fix it? P.S. I also mentioned a problem with being unable to use second "drive", but I'll tackle that problem when (and if) I manage to merge those two devices into one...

  • Why apcupsd won't see the UPS connected to the USB posrt on FreeBSD 8.0 amd64

    - by Max Kosyakov
    Hello, Recently I installed an apcusbd on a FreeBSD 8.0 amd64 box via ports system. It installed perfectly but it won't run. Here what is says in the log: FATAL ERROR in generic-usb.c at line 636 Cannot find UPS device It appeared that HID driver picked the /dev/ugen4.2 which could cause the apcusb being unable to find the device. After I had discovered this, I rebuilt the kernel and removed the hid driver. Now it just shows "ugen4.2: <Tripp Lite> at usbus4" and no uhid0 device appears. Nevertheless the problem persisted. I tried to leave the DEVICE config setting blank --- won't help. Then I specified the particular device in the config, but it did not help either. Below you is the output of several commands that can provide some useful information on my case. server# /usr/local/etc/rc.d/apcupsd start Starting apcupsd. server# tail /var/log/messages | grep apcupsd Jun 17 22:30:00 server apcupsd[1520]: apcupsd FATAL ERROR in generic-usb.c at line 636 Cannot find UPS device -- For a link to detailed USB trouble shooting information, please see .

    First, we create 2 partitions on the USB stick that is let's say 16GB. first partition is let's say only 1GB and the second partition is the rest of what is available. after we "w" write the changes, the USB now has 2 partitions. 1 is 1GB 1 is more than 14GB so , we have... sdb1 and sdb2 now. now we need to turn these partitions into filesystems some say i should run these commands after those procedures. mkfs.vfat -F 32 /dev/sdb1 mkfs.ext3 /dev/sdb2 but some web pages recommend using: mkfs.vfat -n BOOT /dev/sdb1 mkfs.ext2 -m 0 -b 4096 -L DATA /dev/sdb2 which is it? so let's say the DVDs are called: CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso so we make a directory: mkdir -p /mnt/dvd1 and then mount it: mount -o loop CentOS-6.4-x86_64-bin-DVD1.iso /mnt/dvd1 and i suppose we don't make a directory for dvd2 and we don't have to mount it ? at this point i do not know what should be done. but i think this step might be next: we make the USB bootable by finding the file named mbr.bin and then moving it to there via these commnad. dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb parted /dev/sdb set 1 boot on in other words we are "dd-ing it to 'sdb' not sdb1' or 'sdb2'. and then we use parted to set the boot to on for sdb so far everything looks good? here is the confusing parts.. how exactly do i move these iso files to the usb drive? EVERYTHING BELOW IS A GUESS. so at this point i should copy the folder /mnt/dvd1/isolinux to usb's sdb1 or sdb2 ? rename it to syslinux ? and then inside this syslinux folder there will be a file called... isolinux.cfg ? which should be renamed to syslinux.cfg ? and then copy the contents of /mnt/dvd1/images/* to USB's sdb2 ? but i think i am also suppose to copy and paste the both CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso somewhere into this USB's sdb2 partition, correct ? almost like a drag and drop kind of a thing? or do they go into any folders ? centos' own web site has some instructions but those instructions do not work. http://wiki.centos.org/HowTos/InstallFromUSBkey i once got this working but things got ruined, i have to do it again and this time take notes.

  • pptpd configuration

    - by Ian R.
    I would like a little help on configuring pptp so I can use my server as a vpn server since I have 10 ip's on it and I travel a lot so that would really help me and my partners. I managed to install everything needed but my vpn client fails to connect due to some reason that I cannot understand. I know there are 2 files in pptp that you're supposed to edit so I will post my 2 files here: /etc/ppp/pptpd-options name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 proxyarp nodefaultroute lock nobsdcomp /etc/pptpd.conf option /etc/ppp/pptpd-options logwtmp localip xx.158.177.231 remoteip xx.158.177.103,xx.158.177.116,xx.158.177.121,xx.158.177.124,xx.158.177.125,xx.158.177.131,xx.158.177.134,xx.158.177.139,xx.158.177.142,xx.158.177.145 interfaces file eth0 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.231 Bcast:xx.158.177.255 Mask:255.255.254.0 inet6 addr: xx80::216:3eff:fe51:31ba/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:56352 errors:0 dropped:0 overruns:0 frame:0 TX packets:3xx15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4884030 (4.8 MB) TX bytes:6780974 (6.7 MB) Interrupt:16 eth0:1 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.103 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:2 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.116 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:3 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.121 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:4 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.124 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:5 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.125 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:6 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.131 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:7 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.134 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:8 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.139 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:9 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.142 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 eth0:10 Link encap:Ethernet HWaddr 00:16:3e:51:31:ba inet addr:xx.158.177.145 Bcast:xx.158.177.255 Mask:255.255.254.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:3 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:286 (286.0 B) TX bytes:286 (286.0 B)

  • Avoid read-write access to bad sectors on HDD to continue working on the HDD

    - by goldenmean
    I have a HP Pavilion dv6446 notebook. It had Windows Vista Home premium. After 4.5+ years of usage, just recently it started malfunctioning. While working fine, its screen goes white or sometimes some thin black lines horizontally. Laptop freezes. Hard reboot works. Again it works for some 2 hrs or so, same error. To diagnose I did run the Memory and Hard disk check which is present in the Bios Setup. Memory test passed. Hard disk test returned an error saying something like - "Replace the hard disk". Bad.. Some sectors or platters have gone bad on the disk. (I confirmed this later by further tests mentioned below) Then I tried installing a Ubuntu 11.10. It listed 3 partitions /dev/sda1, sda2, sda2. It again gave error and could not install grub loader on /dev/sda1. Bad sectors. Then redid the Ubuntu installation, this time asked to to install the Ubuntu on /dev/sda3. and kept /dev/sda1 for /home. Installed fine, and works fine as well. Due to unavailability of WiFi/ Ethernet driver for that adapters under Ubuntu( at least I could not configure them and get the networking working at all), I decided to go back to reinstall windows Vista. It did install fine. I did not have to format one data partition which has my data. I just formatted one partition which installed Windows So in effect HDD has not undergone a full format here. Worked ok for 1 day. But same white screen and freeze happened. Looks like while it is in use, it accesses the bad sectors for storing some data and that's when it bombs. I am inclined to think HDD has not failed fully or crashed but has developed bad sectors. Else if it was a HDD crash, it would have refused to boot at all let alone install on it. Questions: Is there any HDD test check under windows or any such tools windows/linux based ewhere which can identify the bad sectors of the HDD and 'lock/isolate' them from further read-write access of any kind. If not what are my options, if any to salvage this laptop HDD without replacing it. EDIT: Would the Disk Error checking tool under windows help in any way?
