Getting MSExchange transport Error on Server 2003 SP2

- by Scott

I am getting the following Error messages and do not know how to fix it. Event Type: Error Event Source: MSExchangeTransport Event Category: (8) Event ID: 3017 Date: 4/29/2010 Time: 1:21:12 PM User: N/A Computer: NETSRV Description: A non-delivery report with a status code of 5.3.5 was generated for recipient rfc822;[email protected] (Message-ID <19104335.51321272561635734.JavaMail.SYSTEM@PARROT). Causes: A looping condition was detected. (The server is configured to route mail back to itself). If you have multiple SMTP Virtual Servers configured on your Exchange server, make sure they are defined by a unique incoming port and that the outgoing SMTP port configuration is valid to avoid looping between local virtual servers. Thanks for any help you can provide.

Why can't I grant exec on dbms_lock.sleep() OR create a procedure using it (but I can run it fine on its own)

- by Richard Green

I am trying to write a small bit of PL/SQL that has a non-CPU burning sleep in it. The following works in sqldeveloper begin dbms_lock.sleep(5); end; BUT (as the same user), I can't do the following: create or replace procedure sleep(seconds in number) is begin dbms_lock.sleep(seconds); end; without the error "identifer "DBMS_LOCK" must be declared... Funny as I could run it without a procedure. Just as strange, when I log in as a DBA, I can run the command grant exec on dbms_lock to public; and I get ERROR at line 1: ORA-00990: missing or invalid privilege This is oracle version "Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production"

Moving Windows 7 profile to new user

- by Kevin Grossnicklaus

I have a laptop which I've been using as part of a corporate network with an AD login (and associated local profile). The laptop is loaded with Windows 7 Ultimate. I need to remove the laptop from this domain and, to start this process, I have already configured a local user on the box for me to use moving forward (granting this user the same local admin rights as the AD user). I'd like to migrate all the files, settings, etc from the local AD profile to the new non-AD profile. Is there a simple way to do this? Anything built into Win 7? As far as basic files I can probably just manually copy all the documents, pictures, music, desktop, favorites, etc... But is there a more streamlined way to move profile information? -Kevin

Is there an easy way to read blu-rays on Windows?

- by ereOn

Some time ago, I bought my parents a computer dedicated to medias (mostly photographs and movies trough DLNA). My father asked me if he could read blu-ray on it, so I bought a blu-ray reader but I can't find a software to do the playback. I installed PowerDVD (a free version we got with a Blu-Ray) but it seems it now requires a (non-free) upgrade. Even if it were free, I hardly see my parent do the upgrade by themselves as they barely understand how computers work. I thought I would find a free software (something like VLC, but for blu-rays) but so far had no luck. Do you guys have a software to suggest that would solve my issues ? It should run on Windows Vista, shouldn't require an update every monday, or at least a free one. Thank you very much.

After installing Windows Phone 8 SDK, Connectify doesn't work

- by Pratyush Nalam

Today I installed Windows Phone 8 SDK from the official site. After installing and a couple of restarts (it restarted the PC to enable Hyper-V), I opened Connectify. I use Connectify Hotspot to connect my iPod to the internet as I have an ethernet connection and no wireless router. The problem is that now, Connectify doesn't show WiFi in Share Over. The attached screenshot shows this. Previously, before I installed the SDK, it would show Ethernet and Wi-Fi. I would select WiFi and share my internet. Now, this is completely screwed. EDIT: I found out that the Microsoft Virtual Wi-Fi Miniport Driver has got disabled and I am not able to enable it again. Please advise. Please advise on what to do Hardware: Windows 8 Pro with Media Center, Apple MacBook Pro 9,1 15 inch Mid-2012 (non retina)

Best choice for off-site backup: dd vs tar

- by plok

I have two 1TB single-partition hard disks configured as RAID1, of which I would like to make an off-site backup on a third disk, which I am still to buy. The idea is to store the backup at a relative's house, considerably far away from my place, in the hope that all the information will be safe in the case of a global thermonuclear apocalypse. Of course, this backup would be well encrypted. What I still have to decide is whether I am going to simply tar the entire partition or, instead, use dd to create an image of the disks. Is there any non-trivial difference between these two approaches that I could be overlooking? This off-site backup would be updated no more than two or three times a year, in the best of the cases, so performance should not be a factor to be pondered at all. What, and why, would you use if you were me? dd, tar, or a third option?

RAID10 without write-back cache = horrible write performance?

- by Harry Mexican

I have just provisioned a dedicated server on singlehop. I'm running it through some tests to know what to expect performance-wise. On the I/O side (with 4 1TB disks in RAID 10) I get: write-cache disabled 200 MB/s read throughput 30 MB/s write throughput I thought that was really low compared to my desktop HD which gets 150-150 or so. So I had a chat with them and they suggested enabling the write cache. New results: write-cache enabled 280 MB/s read 260 MB/s write which is great and all but means I'd have to add a BBU for an additional monthly cost. Is it normal for the write throughput to be 1/4 of a regular drive on RAID10, if you don't have write cache? It almost feels like its intentionally bad to force you to pony up for the BBU. I'd be happy with normal non-raid performance of 150/150.

Bash script for mysql backup - error handling

- by Jure1873

I'm trying to backup a bunch of MyISAM tables in a way that would allow me to rsync/rdiff the backup directory to a remote location. I've came up with a script that dumps only the recently changed tables and sets the date of the file so that rsync can pick up only the changed ones, but now I don't know how to do the error handling - I would like the script to exit with a non 0 value if there are errors. How could I do that? #/bin/bash BKPDIR="/var/backups/db-mysql" mkdir -p $BKPDIR ERRORS=0 FIELDS="TABLE_SCHEMA, TABLE_NAME, UPDATE_TIME" W_COND="UPDATE_TIME >= DATE_ADD(CURDATE(), INTERVAL -2 DAY) AND TABLE_SCHEMA<>'information_schema'" mysql --skip-column-names -e "SELECT $FIELDS FROM information_schema.tables WHERE $W_COND;" | while read db table tstamp; do echo "DB: $db: TABLE: $table: ($tstamp)" mysqldump $db $table | gzip > $BKPDIR/$db-$table.sql.gz touch -d "$tstamp" $BKPDIR/$db-$table.sql.gz done exit $ERRORS

Home-Router: Access internal server using external ip [migrated]

- by user15863

If I've got a typical home router -- say a Net Gear -- which has certain ports forwarded to a internal server, is there a way to tweak the router to let me access that internal server using the external IP address from within the same network? Is there a non-enterprise grade router that can handle this type of thing? In case that was strangely worded, let me re-phrase with an example. My external IP is 1.2.3.4. My internal server is 10.4.3.100 Port 1178 is being forwarded from the router to 10.4.3.100. I'd like to be able to be able to hit 10.4.3.100 from an internal ip of 10.4.3.10 by using the external ip of 1.2.3.4. Possible?

How can I convert audio files to this format?

- by jeffamaphone

I have a bunch of audio files that are named .wav but it seems not all .wavs are created equal. For example: $ file * file1.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz file2.wav: Audio file with ID3 version 2.2.0, contains: MPEG ADTS, layer III, v1, 160 kbps, 44.1 kHz, JntStereo file3.wav: Claris clip art? file4.wav: Audio file with ID3 version 2.2.0, contains: MPEG ADTS, layer III, v1, 160 kbps, 44.1 kHz, JntStereo And for good measure, a non-wav: file5.m4a: ISO Media, MPEG v4 system, iTunes AAC-LC I would like to convert all of these files to the format that file1.wav is: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz What is the proper set of arguments to pass to afconvert to make that happen?

copying user profile on windows 7

- by SwissCoder

Is there a tool or a trick to easily duplicate a windows profile? My problem is that I have a local user profile and I like to copy that for another user. Additionaly that profile was created locally when a domain-user logged in, and I like to create a copy of that profile for a non-domain-user. Hope it's clear what my problem is. Thank you for reading! I've just seen there is a similar question: Copy Windows 7 profile from one domain user to another Now I like to know if it is possible to simply change the user-profile's Name and Password. Is this somehow possible?

Error setting up Data Protection Manager 2010 Agents / Network "Unauthenticated" in network settings

- by Bowsa

I'm not sure if the two are connected but i suspect they are. Basically I'm tring to setup Data Protection Manager 2010 on a fresh install of Server 2008 R2 in a SBS 2003 domain. Everything went fine until trying to install agents across the network. Upon clicking add, i get the following error message: Unable to connect to the Active Directory Domain Services Database. Make sure that the DPM server is a member of a domain and that the controller is running. Also verify that there is network connectivity between the DPM server and the domain controller. ID: 7 As usual (worryingly) the MSDN support for 2010 products is nearly non existant, clicking the error ID simply gives a page not found error. So after 2 days of Googling and trying various fixes (DNS settings, adding permissions to GPO objects, rejoining the domain and many more) I thought I'd ask here in the hope that someone out there may have had this issue before. Any help greatly appreciated!

Good option for a transparent internet gateway on Mac OS X

- by Gareth

Hi I have a small network of Mac systems, and would like to add some internal monitoring of our internet usage, which has recently begun to climb. I would like to configure one of the machines as an internet gateway, and install some monitoring software that could provide graph indications of network usage by machine. The machine would then double as a workstation and as the internet gateway. I can manually configure the machines on the network to use it as a gateway, and would prefer to avoid an explicit http proxy (although it is an option if necessary). What software would serverfault users recommend to provide simple, easily configurable and maintainable network monitoring on Mac OS 10.5.7 (non-server)? The simplest requirement is monitor usage by IP Address, but additional tracking (e.g. destination, protocol, etc) would be useful.

Best SQL Server Configuration with this hardware.

- by DavidStein

I just received my new SQL Server from Dell. The server will be serve approximately 15 OLTP databases which average 10GB in size. Here are the basic specs: Dell PowerEdge R510 with up to 12 Hot Swap HDDs,LED Intel Xeon E5649 2.53GHz, 12M Cache, 5.86 GT/s QPI, 6 core (Quantity of 2) 48GB Memory (6x8GB), 1333MHz Dual Ranked RDIMMs for 2 Processors, Optimized PERC H700 Integrated RAID Controller, 1GB NV Cache 300GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 4) 600GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 6) My first thought was to use 3 arrays. OS - Raid 1 - (2)300GB T-Log - Raid 1 (2)300GB DB - Raid 5 (5) 600GB Backup - (1) 600GB - non-raided. However, I could also do the following after purchasing one more drive for backup. OS and T-Log - Raid 10 - (4)300GB DB - Raid 10 (6)600GB The hard drive space is not an issue as the databases are not that large. I'm just trying to optimize the speed of the applications using these databases. So, what would you guys recommend?

How to open embedded Visio files with only Visio Viewer?

- by Christopher Galpin

For some bizarre reason Visio Viewer seems incapable of opening vsd files when they're embedded within a (2010) Excel document: However if I open the Excel document with 7-zip, browse to xl\embeddings, extract oleObject1.bin and rename it to a .vsd file extension it opens perfectly fine with Visio Viewer in Internet Explorer. Since this opens fine on a computer with the full Visio installed, my guess is it's trying to launch Visio rather than IE. Is there something I can do to fix this? I've been scanning with Process Monitor and searching with RegScanner comparing a Visio-installed system to a VisioViewer-installed system and there doesn't actually seem to be any sort of registry value giving direction here... maybe it's just the nature of OLE. (If it can't be fixed I'm okay with converting the extracted one to a .png or so to replace the embedded object, but the "solutions" I've found for vsd to image conversion are very poor or non-working, i.e. buggy code, code with Visio dependencies, or online services.)

Windows7 IIS7: zips don't have php5isapi.dll Can I use php.dll instead?

- by Pete Alvin

The page: How to Install PHP 5.2 on IIS 7and Windows Vista (and a few others) reference a mysterious php5isapi.dll which is not in the Windows install, or the zip files: php-5.3.2-Win32-VC9-x86.zip - VC9 x86 Thread Safe php-5.3.2-nts-Win32-VC9-x86.zip - VC9 x86 Non Thread Safe There was another post on stackoverflow that said it's obsolete and replaced by "fastapi" but no instructions mention this. I did find a php.dll in the zip file. Can I use that instead of php5isapi.dll? It's very frustrating trying to install basic PHP5 on Windows with MySQL.

Get exact size in bytes of a disk & partitions in windows

- by Antonius Bloch

Hi, I'm using dd (under cygwin) to copy a shadow image of a disk in windows. Shadow copy will only give me a partion, so what I am doing is: 1) using dd to grab the disk header (32k on Win2003) 2) using dd to copy the shadow partition 3) using dd to copy the end of of the disk (8 meg reserved on Win2003) 4) stitch them all together and boot on KVM I need the exact size of all the partitions and non partitioned space on this windows drive. Unfortunately most windows disk tools seem to fudge the numbers a bit, or at least give me a different size than Linux does. I could guess like this 32k + partition size + 8M, but I want to double check. If I make a mistake I could lose data. This is on a remote & live Windows 2003 server so no offline solutions will be helpful. Latest cygwin is installed.

How can I connect a SAS drive to USB? [closed]

- by dave

I have a Dell T710 with Seagate Cheetah 15k.7 SAS disks. If the T710 motherboard dies, I'll need to resort to one of my nightly off-site backups and salvage the journal/logfile from the SAS disk to bring the backup bang up-to-date. I need a way of reading the healthy-but-inaccessible SAS disc that does not depend on the only SAS-capable machine I have to hand. So I bought: SAS to SATA Adapter and: USB 2.0 to SATA Adapter with Power ...so that I could read the SAS drive via USB. I can plug it all together just fine. The chain looks like: USB - SATA - SAS. But the drive does not spin up and the computer doesn't even acknowledge anything being attached by USB. Is there a cheap external enclosure I can buy for SAS drives? I can't believe these USB to SATA adapters are everywhere but the USB to SAS adapters are almost non-existent...

Rewrite URL based off of IP on OpenWRT

- by Scott

We are running OpenWRT on a WRT54GL. I have been looking for an answer to this, but I can't seem to figure out what to search for, if its possible, or what combination of programs to use. I want to be able to redirect a HTTP request from a WiFi device based off of their MAC address. This should all be transparent to the device. Basically we are trying to redirect any non-registered devices to a website to register the device (at this point, we would push a new config to the router that would allow this MAC address "full access"). Once a device is registered, it will be redirected to a transparent squid proxy server on another machine for caching/blocking certain sites. I looked at tinyproxy - popilo which redirects but I won't have the MAC address to know if its registered or not. Any help (google suggestions, programs, anything!) would be very much appreciated!

How can private IPV4 addresses get past iptables NAT (tcp RST,FIN)

- by gscott

I've got a router performing simple NAT translation using iptables iptables -t nat -o -j MASQUERADE This works fine almost all of the time except for one particular case where some TCP RST and FIN packets are leaving the router un-NAT'd. In this scenario I setup 1 or 2 client computers streaming Flash video (eg www.nasa.gov/ntv) At the router I then tear down and re-establish the public interface (which is a modem) As expected the Flash streams stall out. After the connection is re-established and I try to refresh the Flash pages, I see some TCP RST and [FIN,ACK] packets leaving the public interface (I assume as Flash attempts to recover its stream). I don't know how these packets can leave the router non-NAT'd

MS Word reports files read-only on Win Server 2003 file server

- by Larry Hamelin

I'm not a sysadmin, but I play one on TV: I'm trying to fix a problem for my mom's tiny non-profit company's server. I set up a Windows Server 2003 machine as a domain controller and file server. Everything has been working well for a few months, but lately when she tries to save changes to a Word (Office XP) document stored on the server, Word will intermittently report that the file is read-only. Saving to an alternate file in the same directory works, and when she closes Word and re-opens the original document, it'll save changes just fine. No one else ever has these files open. I've checked security and share permissions, and everything's OK. We've tried rebooting the server, but the problem continues, but intermittently. I have no clue what's going on. Help!

Hp have stated they're non networkable. Is there anything I can do about this? Any help is greatly appreciated and would save me getting ear ache!

Some general questions about Adobe fonts.

Questions: The Adobe fonts look distinctly clearer and much better than Arial. Any particular reason? Why does Adobe Caslon Pro show up among "C"s? (I know, Caslon starts with "C", but the font's name starts with "A", right?) Are more fonts like these available somewhere? (By "these", I mean non decorative, regular, and smooth) Why are there two versions of certain fonts like Adobe Heiti, which has: @Adobe Heiti and Adobe Heiti (which are not exactly the same, btw.) Thanks.

Disabling file permissions on NFS share

- by user41377

I am trying to set up a nfs share for use by non-technical users, and really don't want file permissions messing things up. Everyone should be able to read/write anything on this share without even knowing what file permissions are, much less adjusting them. Is there a way I can just make the nfs server write everything as 770 or something? It seems like this should be easy, but the best I can come up with is a cronjob to periodically set them to that, which is far from ideal. The server is a Netgear ReadyNAS. Ideally I would like to stick to doing stuff from within the web interface on it, but I can just root it if needed.
