  • Windows XP: How to delete files and folders that cannot be deleted?

    - by glenneroo
    I have a backup copy of a previous Windows' Documents and Settings folder which only contains my original user and within 2 more directories: Favorites and Local Settings. When I try to delete Local Settings I get this error: When I try to delete Favorites, I get this error: I ran this in a cmd shell: attrib *.* -r -a -s -h /s ...but it did not help, nor did it return any errors/warnings. I used Unlocker v1.8.5 and LockHunter repeatedly at multiple levels to see if any files are in use, but both always say: No Files Locked. Update #1: I was able to rename the directory, which now gives me this warning before (trying to) delete: If I press Yes (or Yes to All) then I get this error: Update #2: I let chkdsk /f run which required a reboot since it's on my primary system partition. During Stage 2 scanning, I received about 40 of these: Deleting an index entry from index $0 of file 25. ...followed by: Deleting index entry cookies in index $I30 of file 37576. ...but I still get the first error dialog above when trying to delete. Update #3: Digging deeper, the 99 is the name of one of many directories located deep in here: C:\Documents and Settings.OLD\User\Local Settings\Application Data\Microsoft\Messenger\[email protected]\SharingMetadata\[email protected]\DFSR\Staging\CS{D4E4AE55-B5E2-F03B-5189-6C4DA6E41788}\ Inside each of those directories were files with names such as: 2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-Downloaded.frx I noticed that, unlike all the directories, I couldn't rename any of these files. I also noticed that the file + dir names were extremely long: Original directory = 194 characters Filenames = 100+ characters Together the length exceeds the 255-char limit which is bad and would explain the error message I posted in Update #1. Partial Solution: Rename all directories until the total path length is less than 100. Afterwards I was able to rename the .frx files, not to mention delete everything inside the Local Settings directory. This is only a partial solution because this (empty) directory is still undeleteable: C:\1\2\Favorites\Wien\What To Do.. I'm guessing because of the ".." at the end, Windows (Explorer and cmd) can't deal with it: Here is what Explorer properties shows: Any ideas?

  • Openldap startup problems after upgrade

    - by Craig Efrein
    I am trying to syncrhonize a ldap slave and master server. The master server is using openldap 2.3.43-12 and the slave server is using openldap 2.4.23. I copied over the files in /var/lib/ldap, started the server and got this error: Oct 22 16:16:41 xe-ldap-slave1 slapd[12111]: bdb(dc=myserver,dc=fr): Program version 4.7 doesn't match environment version 4.4 Oct 22 16:16:41 xe-ldap-slave1 slapd[12111]: bdb_db_open: database "dc=myserver,dc=fr" cannot be opened, err -30971.

  • How to burn a data DVD in Windows XP

    - by SabreWolfy
    I am trying to burn a data DVD (DVD+R) in Windows XP SP3 on a Dell desktop computer. The computer has a licensed copy of Nero 6.3. Nero indicates that an update to version 6.6 is available, but after following the link provided, it redirects me to the Nero website to purchase the upgrade. I'm not interested in doing this. After creating a project in Nero 6.3, inserting a blank DVD+R and trying to start burning the data DVD, Nero indicates that I should insert an appropriate disk into the drive. It does not seem to detect the blank DVD+R. I downloaded infrarecorder and cdrtfe from Sourceforge. Neither of these programs worked either. They both indicated that I should insert the correct media, with cdrtfe saying there is no disk in the drive. I tried with another blank DVD +R with the same effect. I inserted a CDR containing data into the drive and the Windows read read this CDR without a problem. I have no reason to believe that the drive is faulty. I am aware that Windows XP itself is not able to burn DVDs. However, it seems that three third-party software programs are not able to burn a data DVD in Window XP. The specifications provided in Nero indicate that DVD+R is compatible with the drive. How can I burn a backup data DVD in Windows XP?

  • Is the APC BR700G UPS (or similar) compatible with Active PFC power supplies?

    - by David Zaslavsky
    I'm looking at getting a UPS for my home computer. So far the APC BR700G looks very promising, except for one thing: one of the reviews on Newegg says that this UPS does not work with a power supply with Active PFC. Pros: Unit looks great, built well, very heavy, was excited to use it. Cons: Didn't research enough - many newer power supplies like my corsair 750w (and yes dells and other mainstreamers sell them too) that I bought last year have a feature called active pfc (power factor corrected). The signal for this backup battery doesn't fully support that feature and can cause issues. You can find an article on APCs site if you search their user forums for PFC. And the power supply in my computer is, in fact, an Active PFC PSU. I've already found one answer on this site claiming that it's not an issue, that "most quality supplies these days have PFC and work just fine with a UPS." That disagrees with the review on Newegg. Can someone explain this discrepancy? Also, what is it exactly about a UPS that makes it incompatible with an Active PFC PSU? (if anything) Is there some way to tell based on the technical specifications, or do I just have to hunt for reviews online to avoid wasting my money? While any input would be appreciated, I would prefer to get an answer from someone with actual experience with similar UPS's and Active PFC power supplies, who can tell me whether it works or not.

  • DNS failover in a two datacenter scenario

    - by wanson
    I'm trying to implement a low-cost solution for website high availability. I'm looking for the downsides of the following scenario: I have two servers with the same configuration, content, mysql replication (dual-master). They are in different datacenters - let's call them serverA and serverB. Users use serverA - serverB is more like a backup. Now, I want to use DNS failover, to switch users from serverA to serverB when serverA goes down. My idea is that I setup DNS servers (bind/powerdns) on serverA and serverB - let's call them ns1.website.com and ns2.website.com (assuming I own website.com). Then I configure my domain to use them as its nameservers. Both DNS servers will return serverA IP as my website's IP. If serverA goes down I can (either manually or automatically from serverB) change configuration of serverB's DNS, to return IP of serverB as website's IP. Of course the TTL will be low, as it's supposed to be in DNS failovers. I know that it may take some time to switch to serverB (DNS ttl, time to detect serverA failure, serverB DNS reconfiguration etc), and that some small part of users won't use serverB anyway. And I'm OK with that. But what are other downsides of such an approach? An alternative scenario is that ns1.website.com will return serverA IP as website's IP, and ns2.website.com will return serverB IP as website's IP. But AFAIK clients not always use primary nameserver and sometimes would use secondary one. So some small part of users would use serverB instead of serverA which is not quite what I'd like. Can you confirm that DNS clients behave like that and can you tell what percentage of clients would possibly use serverB instead of serverA (statistically)? This one also has the downside that when serverA goes back up, it will be automatically used as website's primary server, which is also a bad situation (cold cache, mysql replication could fail in the meantime etc). So I'm adding it only as a theoretical alternative. I was thinking about using some professional DNS failover companies but they charge for the number of DNS requests and the fees are very high (why?)

  • Can I still restore partition table?

    - by Johannes Lund
    Once I was going to resize partitions on my Mac HD from Bootcamp. I changed my mind and was going to quit, but apparently I hit a button, which made every single mac partion dissapear, and windows 7 refused to restart and be reinstalled. The 1 TB large HD consists of 3 partions, I believe. Since I can't see their actual size (except bootcamp), this is how I recall it. Macintosh HD about 500GB (Somewhere around 700GB according to disk utillity, but 500 according to Finder, and 500GB was all I could access.) Lion Recovery disk Bootcamp 293.36 GB To fix this I connected my mac via target disk mode to a pc and ran TestDisk. However this is the results: Since I Don't have 10 reputation I cant post the image showing the testdisk results, so I post a link instead hoping it is ok. The two mac partitions' sizes are completely wrong, and BOOTCAMP isn't showing. I tested using disk utilities from the snow leopard dvd. There there is one 293.36 GB Mac OS Extended partition. Before I had the firewire cable for target disk mode I tried reinstalling windows. Without success I tried again formating BOOTCAMP. Was that a bad thing to do? Could it have overwritten data from Macintosh HD? Unfortunately I have no backup. I could bring it to some kind of computer repair firm though.

  • How to create Windows Vista/Windows 7 Startup disk or Rescue disk or system restore points on a CD?

    - by goldenmean
    Hello, I have two laptops, one having Windows-Vista home premium and other one having Windows-7 professional. Both versions of OS are OEM installs(pre-installed when I bought the laptop) and I do not have the Windows Installation disks for them. usually the installation disks provide a repair option in case one needs to repair/rescue a improper windows installation. But since I dont have the installation disks, I want to create rescue disks/startup disks for these. My questions are : 1] How to create a system rescue disk/startup disk on a CD from these two versions of Windows? 2] Doesn't the system restore points which Vista/Windows-7 create, cannot be created on a CD disk instead of hard-disk? 3] If I have a manual backup of my windows registry, in which I have exported all the registry to a file and I have that file on a CD, how to restore that registry back to the windows installation which might not be booting up properly due to bad registry problem. EDIT: 4]Is there any way to use these system restore points directly during bootup of the laptop, if windows does cannot boot properly due to problem. First laptop is HP Pavillion dv6646 and second one is Sony VAIO VCPEE series. thank you. -AD

  • On AWS EC2, Unable to run sudo command after modifying permissions to /usr folder

    - by Kayote
    All, We have searched quite a bit and a few of 'Eliah Kagan's' posts are great about getting access back to sudo. However, our server is on AWS EC2 & I am a complete newbie to this. We are trying to setup Cronjobs for backing up our server data. What we did: Using Putty, we created a script file: usr/share/site-db-backup/backupToS3.php, however, Ubuntu was not saving the changes we made as it reported we did not have permission as user 'Ubuntu'. Error details are: "Upload of file backupToS3.php was successful but error occurred while setting the permission &/ or timestamp. If the problem persists, turn on 'ignore permission errors' option. Permission denied. Error code: 3 Request code 9" So, we ran the command "sudo chmod -R a+rwx /usr" for granting permission to the folder 'usr'. However, now whatever sudo command is run, we get the error: "/usr/lib/sudo/sudoers.so must be only be writable by owner. fatal error, unable to load plugins." We are complete newbies to Ubuntu & EC2 so do need step by step guidance of how to get sudo back & successfully write to the Crontab script sitting in 'usr/' folder.

  • Dovecot (on Mac OS X Server 3 - Mavericks) giving “Error: Failed to autocreate mailbox INBOX: Permission denied”

    - by user2965240
    I recently upgraded my server to Mavericks and I thought everything had gone perfectly. As it turns out, that was not exactly the case. After everything working fine for a week or so, I created a new user and my mail server flat out stopped working. Most frustratingly, there were no log errors (in any of the many mail logs) which shed any light on the cause. After much trial and error, I finally got my mail server functioning (partially) by reinstalling server and restoring the mail folder from the previous day's backup (yay for backups). However, as is often the case, there were MANY permission issues. After slogging through various permission problems, I believe that my system is now receiving mail, however none of my users can check it because every time someone attempts to login the server generates following error: Error: Failed to autocreate mailbox INBOX: Permission denied I would assume that this is yet another permissions problem, however after much searching, I still cannot resolve this. To be clear, I don't want Dovecot to autocreate any mailboxes at this point because all of the mailboxes should exist. Any help on this would be sooooooo greatly appreciated. P.S. On a side note: why is it that repairing permissions never takes care of difficult issues like these? That would be awfully helpful...

  • Migrate Windows Server 2008 to a new hard disk

    - by MainMa
    Hi, I have a machine with Windows Server 2008. I want to change the hard disk drive, but keep everything else. I don't have a cd/dvd drive and don't want to buy it. My first idea was to make a byte-to-byte copy of the disk with Paragon Advanced Recovery. The problem is that when I try to boot from a new hard disk, it says that there were hardware changes and that Windows must be repaired, inviting me to insert the installation disk and follow repair instructions. I searched and found that 1:1 copy is not a correct way to do things. The correct one is to restore Windows to a new hard disk from a full system backup. But to restore, I need to have a dvd drive. I tried to make a copy of the Windows Server 2008 .iso on an USB flash drive, but the drive is not bootable (while the same procedure applied to Paragon Advanced Recovery ISO produces a bootable recovery USB flash drive). Now what else can I do (except buying a dvd drive)? Is there a way either to make Windows work without doing recovery or recover Windows 2008 without using a cd drive?

  • Windows 7 Won't Boot

    - by Vie
    I recently built a new computer, my fifth one. ASUS Maximus III Formula LGA 1156 Intel P55 ATX Motherboard EVGA 01G-P3-1452-TR GeForce GTS 450 Superclocked 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Video Card COOLMAX RM-1000B 1000W ATX psu Intel Core i7-875K lynnfield 2.93GHz LGA 1156 95w Quad-Core unlocked processor G.SKILL Ripjaws Series 16 (4x4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) memory WD VelociRaptor WD3000GLFS 300gb 10000 RPM SATA 3.0Gb/s Hard Drive Sony Optiarc CD/DVD Burner model AD-7261S-0B LightScribe Windows 7 Home Premium 64-bit It gets hung up on the starting windows screen. When I went to install the OS it did the same thing wouldn't go past the windows logo, so I put the new HDD into my old computer and installed windows 7 thinking it was just an installer error. Put the fully installed HDD back into my new machine and it still gets stuck on the starting windows screen. I've tried most everything I've looked up. Disabled USB, Disabled Turbo Boost, Disabled everything that wasn't essential(just about every configuration I can think of), took it apart and put it back together, took all the ram out save one 4g stick(wouldn't even boot when I did this), did a memory scan which came back successful, I don't know what could be wrong. Only thing I can think of is a compatibility issue somewhere, but I've ran over it again and again and I don't know where there would be an issue like that. Need Backup! .<

  • Archive Manager, SQL 2005 and MaxTokenSize high CPU

    - by Tim Alexander
    So, I posted this question a few days ago: Impact of increasing the MaxTokenSize for Kerberos Tickets Since then the thought was to test our settings on two member servers, one with IIS and one without. I setup two GPOs to configure the MaxTokenSize reg setting to 48000 and MaxFieldLength/MaxRequestBytes to 64200 (based on MS KB2020943, these are set at 4/3 * T + 200). The member server seemed to work ok (a devalued tape backup server). The IIS server however has had some strange repercussions. The IIS Sserver host Quest Software Archive Manager (AM) 4.5 that communicates with SQL Server 2005 Enterprise on Server 2003 R2. After the changes all looked good until the SQL Server hit 100% CPU. I have removed the GPOS, removed the reg values and even replaced them with defaults (12000 for token size and can't remember the other one but was in a blog post about the issue in my other post). No change. Bouncing the IIS Server stops the high CPU and a colleague has looked at the SQL server and it is definitely the AM connection taking up the time/work on the SQL server. I haven't changed the reg values on the SQL server or the DCs but am reluctant to do so without understanding why this has happened. I am guessing its to do with the overriding auth and group issue we have but I am not seeing Kerberos errors in either event log. Has anyone seen something similar or does anyone have some tips? Was definitely blindsided by the Kerberos issue and am swimming against the tide to keep things functioning.

  • v2v of RHEL5 box - issues with retaining MAC address

    - by Alex Berry
    For the last week we have been troubleshooting a customer's Red Hat Virtual Machine running on ESXi. We've been using Veeam to try to create a replica off-site and have been having getting it to work on a decent schedule and recently we noticed that there were issues with orphaned snapshots while looking at the datastore. You can see several snapshots in the same folder and it's causing issues with replication and backup, so we decided the cleanest way was to v2v the machine to another datastore so that we had a clean single-vmdk setup to work with, this is where our trouble started. We first started off with a v2v using vmware converter and connecting to the powered on machine as we were having issues doing an offline v2v. This copied fine but when I tried to set a static MAC using this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=507 the new VM wouldn't take the address, it simply obtained a new MAC, received a dhcp lease and then would only boot up to a blank red screen, never the login screen. So the next step was to do an offline v2v, once we finally got it working. Same thing, followed the kb to the letter and still it wouldn't take the MAC. I then tried it again and upon completion I compared both old and new VMX file, copying every identifier and variable possible, then unregistered both VMs, uploaded the new VMX file and booted, only to see the same results. Finally I did the same as above but I copied the disk using DD to a second attached vmdk and then attached this to the new VM, and still no luck. After downloading the modified VMX file after the first boot and comparing it to the original I created I found that the bios uuid had changed from the one I typed in manually, so I'm assuming this may be the snagging point, but I have no idea. I've never had this issue before on a P2V and I'm just wondering if someone could shed some light on this, maybe it's to do with RHEL licencing?

  • How important is dual-gigabit lan for a super user's home NAS?

    - by Andrew
    Long story short: I'm building my own home server based on Ubuntu with 4 drives in RAID 10. Its primary purpose will be NAS and backup. Would I be making a terrible mistake by building a NAS Server with a single Gigabit NIC? Long story long: I know the absolute max I can get out of a single Gigabit port is 125MB/s, and I want this NAS to be able to handle up to 6 computers accessing files simultaneously, with up to two of them streaming video. With Ubuntu NIC-bonding and the performance of RAID 10, I can theoretically double my throughput and achieve 250MB/s (ok, not really, but it would be faster). The drives have an average read throughput of 83.87MB/s according to Tom's Hardware. The unit itself will be based on the Chenbro ES34069-BK-180 case. With my current hardware choices, it'll have this motherboard with a Core i3 CPU and 8GB of RAM. Overkill, I know, but this server will be doing other things as well (like transcoding video). Unfortunately, the only Mini-ITX boards I can find with dual-gigabit and 6 SATA ports are Intel Atom-based, and I need more processing power than an Atom has to offer. I would love to find a board with 6 SATA ports and two Gigabit LAN ports that supports a Core i3 CPU. So far, my search has come up empty. Thus, my dilemma. Should I hold out for such a board, go with an Atom-based solution, or stick with my current single-gigabit configuration? I know there are consumer NAS units with just one gigabit interface (probably most of them), but I think I will demand a lot more from my server than the average home user. Any advice is appreciated. Thanks.

  • hp DL380 G4 won't boot with disk plugged into front USB

    - by Kev
    We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

  • Keepalived for more than 20 virtual addresses

    - by cvaldemar
    I have set up keepalived on two Debian machines for high availability, but I've run into the maximum number of virtual IP's I can assign to my vrrp_instance. How would I go about configuring and failing over 20+ virtual IP's? This is the, very simple, setup: LB01: 10.200.85.1 LB02: 10.200.85.2 Virtual IPs: 10.200.85.100 - 10.200.85.200 Each machine is also running Apache (later Nginx) binding on the virtual IPs for SSL client certificate termination and proxying to backend webservers. The reason I need so many VIP's is the inability to use VirtualHost on HTTPS. This is my keepalived.conf: vrrp_script chk_apache2 { script "killall -0 apache2" interval 2 weight 2 } vrrp_instance VI_1 { interface eth0 state MASTER virtual_router_id 51 priority 101 virtual_ipaddress { 10.200.85.100 . . all the way to . 10.200.85.200 } An identical configuration is on the BACKUP machine, and it's working fine, but only up to the 20th IP. I have found a HOWTO discussing this problem. Basically, they suggest having just one VIP and routing all traffic "via" this one IP, and "all will be well". Is this a good approach? I'm running pfSense firewalls in front of the machines. Quote from the above link: ip route add $VNET/N via $VIP or route add $VNET netmask w.x.y.z gw $VIP Thanks in advance. EDIT: @David Schwartz said it would make sense to add a route, so I tried adding a static route to the pfSense firewall, but that didn't work as I expected it would. pfSense route: Interface: LAN Destination network: 10.200.85.200/32 (virtual IP) Gateway: 10.200.85.100 (floating virtual IP) Description: Route to VIP .100 I also made sure I had packet forwarding enabled on my hosts: $ cat /etc/sysctl.conf net.ipv4.ip_forward=1 net.ipv4.ip_nonlocal_bind=1 Am I doing this wrong? I also removed all VIPs from the keepalived.conf so it only fails over 10.200.85.100.

    We use Exim on our servers to send emails only from local automated users, as root, cron, etc. We have to specify every possible users into /etc/email-addresses. For example: root: [email protected] cron: [email protected] backup: [email protected] This allow us te receive every email generated. The problem is when we add a user for whatever reason (for example when we add a package, some add a user), we can forget to add this user to /etc/email-addresses. Most of the time it's not a problem, but this is not clean. And the overall method is not clean. We'd like to configure Exim to send every emails with the same source address. i.e. every sent email comes from [email protected] One way could be to use a wildcard or a regular expression into /etc/email-addresses but this is not supported. I don't currently understand Exim enought to figure out how to modify this in a way or another. Ideally, Exim should look into /etc/email-addresses first, and if no match it use the predefined address. But this is very secondary. There are two places where this address is used: 1. when Exim send the FROM: command to the smtp server 2. inside the header edit: The rewrite section is the original one from Debian begin rewrite .ifndef NO_EAA_REWRITE_REWRITE *@+local_domains "${lookup{${local_part}}lsearch{/etc/email-addresses} \ {$value}fail}" Ffrs *@ETC_MAILNAME "${lookup{${local_part}}lsearch{/etc/email-addresses} \ {$value}fail}" Ffrs .endif (comments removed)

  • Need advise for choosing software\hardware for virtualization.

    - by Anatoly
    Currently we have these servers : Windows SBS 2003 premium on IBM X266 double Xeon F43, 2GB ram. DC, exchange (70 users), Mssql. Windows 2003 R2 32bit on IBM x3400 with double XEON E5310 and 4GB ram. Terminal server (40+ users), ERP application based on uniPaaS platform from Magicsoftware, and Pervasive sql. Ubuntu 8.04 (simple pc box) with squid proxy, GLPI system and PHPBB3 forum for internal use. Recently number of concurrent users on Terminal server passed 40 users in rush hours and it gets stuck frequently. Therefore we need an upgrade. I think about transfer all physical servers to virtual servers based on cluster of 2 physical servers for reducing downtime. I think we will grow till 50-60 concurrent terminal users in rush hours. I also plan to virtualize 10-15 Win XP/7 workstation (office,ERP etc), and there is a little probability for Asterisk\Hylafax for 100 users (if it possible on same VM). Also we need NAS storage for 2-3TB. What hardware upgrade/purchase we need for complete this task? Which VM solution is preferable VmWare or Hyper-V? What backup software should we choose? Acronis or something another? Thank you in advance.

  • Replacing DropBox with: Amazon S3 + SSL + GPG/TrueCrypt + Mounting on OSX ??

    - by Matt Rogish
    So, right now we're using DropBox to share various data files around between approximately 10 Mac OS X systems. However, we already have an S3 account and everyone on the lowest DropBox plan of $10/mo seems too expensive. So, I am contemplating something that would allow us to replace DropBox with our own home-grown solution. We are all fairly technical people and/or smart enough to follow some steps, so if it's not as "user friendly" as DropBox we're all comfortable with that. There are plenty of docs out there that have bits and pieces of what I want but some of the tools don't seem to fit the requirements: Transport security via SSL to the bucket Encryption of bucket contents Bi-directional syncing Most of the scripts I can find on the internet use "duplicity" which appears to fail #1 (it doesn't look like duplicity supports SSL to S3 - the docs don't state but the protocol looks plain old http http://www.nongnu.org/duplicity/duplicity.1.html#sect6 ) Many scripts use gpg to encrypt files. This seems like it could work, however I have to make sure that each OSX client is able to use the same key to encrypt and decrypt files (key management is left to me to manage). Finally, most of the scripts use one-way replication, e.g. using Amazon S3 as a simple backup store. As we'd be using Amazon S3 as the "repository" they fail this one. Whew. So, I'd love a single tool that does this but after an exhaustive search I don't think one exists. I'd be happy just knowing which tools out there can fulfill my 3 requirements, after that I can stitch together the rest. Any thoughts? THANKS!

  • Software to monitor bill payment to mission critical IT service providers (ISP, DNS etc.)

    - by Sholom
    Hi All, The Problem: Our very likable but absent minded bookkeeper keeps neglecting to pay our IT vendors on time. Just this past week our internet service was disconnected. Same could happen to many other mission critical accounts (domain registrar, backup MX, anti-virus license, HackerSafe (McAfee secure) service and even an 800 number to name a few). As the sysadmin, i monitor my severs to make sure they are plugged into the power-outlet. I believe i should also monitor my services to make sure they are plugged in to their money-outlet. To compound the problem, when the power goes out someone else will likely notice and notify me. But if a bill is not payed, no one will ever notice until service is lost. Lost as in losing our domain name which would cause a lot more damage then the power failing on our server. [Solution] = [Doesn't work because]: Retrain the bookkeeper = Wishful thinking. Notify my manager = Already have (via email). Protects me, does not solve problem. Fire bookkeeper = What makes you so sure the next one will never forget? Bottom line: Humans are humans and sooner or later something critical will be royally messed up. We need to partner with a machine to help us out here. Anybody have the same problem? What software/solution do you use? I would like software that emails me when a bill is passed due just like i get an email when the power outlet fails. Anyone hear of anything like that? Thanks

  • How do I replicate Gmail filtering (forwarding mostly)?

    - by projectdp
    I have reached the limits of Gmail forwarding. Before there was no need to verify forwarding addresses. It's a problem for me now because the addresses I want to forward to are not natural inboxes but automated systems with no way to track the verification email contents. I want to set this up for example: mobile - email - facebook-email - flickr-email - tumblr-email - posterous-email How do I do this without Gmail filters? I think I need to use fetchmail to watch my inbox and then autoforward to the above addresses. Is fetchmail the best solution to this issue? Any other MRA's? I'd like to do some more complicated things with the emails in an automated fashion too, how would I go about monitoring the inbox, doing some actions to the email before forwarding, and forward everywhere? prerequisites: a server: fetchmail daemon to poll the account local mailbox script to clean & forward appropriately (python probably) sendmail + ~/.forward file backup email account (Gmail probably) Any help would be greatly appreciated. I'm trying to automate my social content distribution.

  • Subdocument in Word won't save

    - by ChrisW
    Because I know Word has a history of not liking very large documents (my supervisor specifically told me not to use LaTeX... grr), I decided to learn the Master document / subdocument feature of Word when writing my PhD thesis. I have the title page / table of contents etc in the master document, and each chapter as a separate document. However, when I save the master document, it appears to save all the chapter documents apart from one (Chapter 4), for which it brings up the Save Document dialog box, helpfully with "Chapter4.docx" in the "Save as" box (n.b. Chpater4.dox is not open). Clicking save does nothing, and doesn't make the dialog box go away. Saving as a different document means that my changes aren't reflected in the same document. There must be some reason Word doesn't like this particular document but I've got no idea why - there's nothing special in it that isn't in any of the other chapters. I have tried closing all documents, renaming Chapter4.docx, opening the master document, expanding all documents, OKing the warning that Chapter4.dox does not exist, and inserting the 'new' document, but even when I save the master document it still won't save the new Chapter4 document. If anyone knows any reason why Word is acting like this (or if I'm doing anything stupid), I'll be eternally grateful (p.s. sorry for the long rambling message. It's late; I've been working on my PhD 4.5 years, I really really want to throw this computer out the window, and I hope people are kind enough not to downvote this question because of it's rambling nature!) Update With Word closed, I've tried to delete Chapter4.docx (having made a backup!) - but I get a warning that it can't be deleted because it's open in Microsoft Word... these files are on a network drive and the same problems are happening on 2 different computers. I could login to the filestore through ssh and force the file to be deleted, but I'm curious to know why this is happening!

  • Fix bad superblock on logical partition

    - by Chris
    I was following http://www.howtoforge.com/linux_resi...xt3_partitions and when i reboot and run: root@Microknoppix:/home/knoppix# fsck -n /dev/sda7 fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) fsck.ext2: Superblock invalid, trying backup blocks... fsck.ext2: Bad magic number in super-block while trying to open /dev/sda7 The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device> so i ran e2fsck with all the block numbers that you need (forget exactly what tool i used to find where the superblocks are hidden) no dice then i ran testdisk and had it look for the superblock, no results anyone have any ideas? fdisk -l for reference: root@Microknoppix:/home/knoppix# fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x97646c29 Device Boot Start End Blocks Id System /dev/sda1 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 64 38912 312046593 f W95 Ext'd (LBA) /dev/sda5 64 326 2104320 82 Linux swap / Solaris /dev/sda6 * 327 2938 20972544 83 Linux /dev/sda7 2938 38912 288968672+ 83 Linux To be honest it looks like I lost it... Next step if that happens is to dump the partition to an image file and hope i can find or write some software to parse through the data looking for known file headers, i think.

  • Win Svr 2003 DHCP Bad Addresses

    - by VinceM
    After looking at other posts I still can figure this out. I'll start at the beginning... I inherited this network and I'm not the most knowledgeable about networking... We have a AD DHCP Server that is also our DNS server, We were having some VPN issues (on the same server) and my boss decided to disable routing and remote access, which cleared the settings. We couldn't get it set back up correctly so we rolled back to a backup drive they created a number of months ago. Since rolling back I've had Bad_Address listings in DHCP and there is a number of duplicate records in the DNS Forward Lookup Zones. We have less than 50 devices on the network but I have over 90 Bad Addresses showing. This server is currently running but we get IP address conflicts all the time on pretty much all the computers. I have had people do release and renew but it didn't help... I have also deleted and re-added the scope to no avail either. Any help or ideas would be greatly appreciated and I apologize if I missed another post that has information to help. Thanks, Vince
