  • How can I avoid my web browser from redirecting to localhost using WAMP in Windows7?

    - by Josh
    I'm currently using Windows 7 with WAMP to try and work on some software, but my web browsers will not accept cookies from the "localhost" domain. I tried creating a few bogus domains in my hosts file by pointing them to 127.0.0.1 but when I type them in I am automatically redirected back to localhost. I have also configured virtualhosts in apache to correspond with the domains I added to the hosts file and it still redirects back to localhost. Is there anything special I must do on Windows 7 to get around this localhost redirect? Thanks for looking :) I'll include my host file here: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost 127.0.0.1 magento.localhost.com www.localhost.com Thanks for looking :)

  • QR Codes Printing, but Not Printing Correctly - Any Ideas?

    - by SDS
    I am mail merging some QR codes via file paths stored in Excel into a label template in MS Word 2013. I have the whole process with the Ctrl+F9 working properly, but I am stumped on this: On the 30 label sheet I am trying to print I have 6 labels that are repeating information, and stored in duplicated rows in Excel for this print job. All of the labels have 2 images on them, one is a logo and the other one is a unique QR code for that person. For the first set of 6 labels that print out, everything works perfect. However, from the 2nd time the information is printed onward all of the merged fields and logo look correct, but the QR codes are printing strangely. Basically it's the QR code as I want it, but with a copy of itself covering the top left 25% of the QR code. Print preview doesn't show this happening, only once it's printed does it come out like this. I've been trying everything I can think of to fix this and don't know what to do. So far I've: Recreated the document several times, tried duplicating the images in the source folder and giving the links in the Excel document new file paths in case the mail merge feeding from the same .jpg was an issue (even though it's not a problem with the logo) Any help or insight is greatly appreciate because this is a test run for a larger batch run that I need to get done soon :( Thank you!

  • Google Chrome is running my system out of memory

    - by jasondavis
    I am running Windows 7 x64 with 12GB of RAM I often have multiple windows and a ton of tabs open. I use the extension Session Buddy to restore all my windows and tabs once the memory gets too high. So my 12gb of ram will get up to around 93% used because of Chrome, now I can close chrome down and restore the same amount of windows and tabs and it will only use about 25% of memory, it then over time increases back up to the 90% zone after several hours. It seems that when I close tabs, instead of freeing that memory up, it doesn't so that is why the huge increase of memory usage as new tabs are opened and closed it just adds up, this sounds like a huge bug in chrome. Just for an example I just re-booted my system, I only have 1 window with 4 tabs open and in the task manager, it shows 29 chrome.exe processes I then killed all chrome processes and opened a chrome window with just 1 tab, it made 27 chrome.exe processes. Is this an issue that others have? More importantly, is there a fix? UPDATE I just read that each plugin and extension creates a chrome.exe process, I then couunted 24 extensions so that helps explain a portion of the large processes. Still not sure about memory not being freed up though!

  • Can SSH into remote server but can't SCP?

  • How to remotely connect using perfmon?

    - by user36914
    Suprised there is not a ton of information on google when i search for this but there is not. Lot of people asking the question but i none of them have any good answers. I have a remote computer running hyper-v (server) running a Windows 7 x64 guest (guest). Occasionally i won't be able to remote desktop to guest. I will then remote to server and see that the guest instance is constantly using about 25% of the cpu. WHen i try to connect directly from server i will get the login screen but as soon as i type the password in it will just stay at the windows 7 login screen but the account names will disappear and it will not log in. It responds to pings though. I don't know how else to diagnose other than trying to run perfmon remotely. It only happens like every 3 weeks and i run it 24/7. So i'm trying to run remote desktop remotely. I tested this out on a local vm i have running under vmware. When i try to connect using perfmon to my local vm i get this error: "when attempting to connect to the remote computer the4 following system error occurred: the network path was not found" I found in another past to start the remote registry service and when i start the service i get this error: "No such interface supported" Anyways, how do i remotely connect to another machine with perfmon or if anyone has a better idea how i can diagnose the problem above then let me know.

  • How to kill ostensibly immortal process?

    - by DeeDee
    I had some huge file transfers operating on an NFS mount. The server on which the mount point resided was carelessly rebooted, and now the server from which these large transfers were initiated seems to be bogged down by them. If I run top, I see the following: The first thing I tried was to run kill with each the -1 -2 -9 and -15 flags, and each of the process ids shown above in turn. This allowed me to proceed, but didn't kill the processes. The next thing I attempted was to reboot the server, but neither reboot nor shutdown -r now worked. When I ran shutdown -r now the standard broadcast message was sent out, but the sever did not reboot. I confirmed this by looking at the server uptime, which was 25 days. So now I'm a little stuck. I'm running these commands as root. EDIT: Here's another interesting tidbit: In top, I don't see that any other processes are using more than a fraction of a percent of memory or more than 5% of CPU. EDIT 2: output of /var/log/messages

  • Very Slow DSL (ethernet) speed [New Interesting Update]

    - by Abhijit
    Very IMPORTANT and INTERESTING UPDATE: Due to some reason I just thought to do a complete new setup and this time I decided to again have openSUSE plus ubuntu. So I first reinstall lubuntu and then I installed OpenSUSE 12.2 (64 bit). Now, my DSL speed is working very normal and fine on opensuse. So this is very scary. Is it possible for any operating system to manipulate my NIC so that it will work fine only on that operating system and not on another os? Regarding positive thinking and not being paranoid, what is it that makes ONLY suse to get my NIC to work at normal speed but ubuntu can not do it? Not even fedora? Not even linux mint? What all these OS are lacking that enables suse to work great? == ORIGINAL QUESTION == I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.

  • postfix test and configuration problem

    - by Woho87
    Hi Guys! I installed postfix using sudo yum install postfix postfix-mysql. I'm newbie to mail systems, but I have one AMAZON EC2 instance with a public DNS. I used the public DNS in most cases, when I configured the file main.cf. The public DNS I have is from amazon and it is a long string(ec2-123-34-234-677.....amazon.com). // I configured this on main.cf. I replaced example.com with ec2-123-.......amazon.com myhostname = mail.example.com mydomain = example.com myorigin = $mydomain mydestination = example.com, $transport_maps local_recipient_maps = $alias_maps $virtual_mailbox_maps unix:passwd.byname home_mailbox = Maildir/ How do I test postfix? I just want it to send emails for my web application. I tried to test it with >telnet localhost 25 after I typed in SSH >sudo postfix start. but I recieve the message that telnet command can not be found. I also use the Amazon linux distribution if you want to know. I use it because it is free. What have I done wrong? Are there anymore configurations required pls help!

  • Force delivery retry without restarting the SMTP Service on Windows Server 2008 R2

    - by Mathias R. Jessen
    I have a Windows Server 2008 R2 box hosting 3 virtual SMTP servers; vSMTP01, vSMTP02 and vSMTP03. The first two are configured to deliver all messages to dedicated smarthosts, while the last is set to just deliver the messages on its own. All other delivery settings are as default ----(vSMTP01)-----> {SMARTHST01} / ----Inbound mail--->---SMTPSRV01---[----(vSMTP02)-----> {SMARTHST02} \ ----(vSMTP03)-----> { Internet } Now I want to take SMARTHST01 out for maintenance, but I don't want to reject submissions to vSMTP01 while doing so, so I just let it continue running. When SMARTHST01 is no longer responding, vSMTP01 queues the messages and wait for the first retry interval to pass (15 minutes). So far so good. Let's say SMARTHST01 gets online again after 20 minutes. The first interval has passed, and I'll have to wait another 25 minutes for the second retry interval to pass. If I stop and start the SMTP Service (Services.msc - Simple Mail Transfer Protocol service - Stop), the server will retry all deliveries, but that would cause a service interruption for ALL virtual SMTP servers on the machine, which is highly undesirable. How can I manually force vSMTP01 to retry delivery of all queued messages without interrupting the service of vSMTP02 and vSMTP03?

  • ERROR: Not enough space?

    - by dsmoljanovic
    Now this is a very unspecific question. I'm trying to figure out what this message would mean. Here is the story behind it: I'm installing Oracle enterprise manager cloud control (12c r3) on Solaris 10 (5/09). Installer opens up, i enter all needed information and at the last step click Install. It immediately crashes with only "ERROR: Not enough space" written in log and console and nothing else. Now, this could be java error or Solaris error? I'm thinking it's happening either when it starts to copy files or when it tries to launch a process that would do that. What space is it referring to? disk (have ehough), swap (also), memory (yep)... Any ideas are helpful. Edit: i found this exception in the oraInventory logs: oracle.sysman.oii.oiic.OiicInstallAPIException: Not enough space at oracle.sysman.oii.oiic.OiicAPIInstaller.initInstallSession(OiicAPIInstaller.java:2165) at oracle.sysman.oii.oiic.OiicAPIInstaller.initOUIAPISession(OiicAPIInstaller.java:790) at oracle.sysman.install.oneclick.EMGCOUIInstaller.prepareForInstall(EMGCOUIInstaller.java:676) at oracle.sysman.install.oneclick.EMGCSummaryDlgonNext$1.run(EMGCSummaryDlgonNext.java:243) at java.lang.Thread.run(Thread.java:662) at oracle.sysman.install.oneclick.EMGCSummaryDlgonNext.actionsOnClickofNext(EMGCSummaryDlgonNext.java:1067) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at oracle.sysman.install.oneclick.EMGCUtil.performonClickOfNextForClass(EMGCUtil.java:399) at oracle.sysman.install.oneclick.EMGCUtil.performPageLevelValidationsForSilentInstall(EMGCUtil.java:367) at oracle.sysman.install.oneclick.EMGCInstaller.prepareForSilentInstall(EMGCInstaller.java:1459) at oracle.sysman.install.oneclick.EMGCInstaller.main(EMGCInstaller.java:1553) disk status: bash-3.00$ df -h /tmp Filesystem size used avail capacity Mounted on swap 8.1G 2.7G 5.4G 33% /tmp bash-3.00$ df -h /u01 Filesystem size used avail capacity Mounted on / 275G 28G 244G 11% / swap: root@gs12emcc # swap -s total: 18306040k bytes allocated + 3837808k reserved = 22143848k used, 5712664k available

  • logfile deleted on Oracle database how to re-create it?

    - by Daniel
    for my database assignment we were looking into 'database corruption' and I was asked to delete the second redo log file which I have done with the command: rm log02a.rdo this was in the $HOME/ORADATA/u03 directory. Now I started up my database using startup pfile=$PFILE nomount then I mounted it using the command alter database mount; now when I try to open it alter database open; it gives me the error: ORA-03113: end-of-file on communication channel Process ID: 22125 Session ID: 25 Serial number: 1 I am assuming this is because the second redo log file is missing. There is still log01a.rdo, but not the one I have deleted. How can I go about recovering this now so that I can open my database again? I have looked into the database created scripts, and it specified the log02a.rdo file to be size 10M and part of group 2. If I do select group#, member from v$logfile; I get: 1 /oradata/student_db/user06/ORADATA/u03/log01a.rdo 2 /oradata/student_db/user06/ORADATA/u03/log02a.rdo 3 /oradata/student_db/user06/ORADATA/u03/log03a.rdo 4 /oradata/student_db/user06/ORADATA/u03/log04a.rdo So it is part of group 2. If I try to add the log02a.rdo file again "already part of the database". If I drop group 2 and then add it again with these commands: ALTER DATABASE ADD LOGFILE GROUP 2 ('$HOME/ORADATA/u03/log02a.rdo') SIZE 10M; Nothing. Supposedly alters the database, but it still won't start up. Any ideas what I can do to re-create this and be able to open my database again?

  • How do you set up CRON?

    - by user1723760
    I have never used CRON before but I want to use CRON in order to be able to perform schedule jobs for a php script. The php script is called "inactivesession.php" and in the php script is this code: <?php include('connect.php'); $createDate = mktime(0,0,0,10,25,date("Y")); $selectedDate = date('d-m-Y', ($createDate)); $sql = "UPDATE Session SET Active = ? WHERE DATE_FORMAT(SessionDate,'%Y-%m-%d' ) <= ?"; $update = $mysqli->prepare($sql); $update->bind_param("is", 0, $selectedDate); $update->execute(); ?> Wht I want to do is that when the above date is reached (25th Oct), I want the php script to perform the UPDATE statement above. But my question is that how do I use CRON in order to do this? The server I am using is the university's server known as helios, does CRON need to be set up in helios, (do I have to call the admin for this) or is it something else which uses CRON. I have never used CRON before so can you explain to me how CRON can be set up for the example above with the server I am using? Thanks UPDATE: Hi, I think the name of the OS is actually helios but I am not sure, I have a wikipedia page on this: here. I will read the crontab wikipedia page and see what I can find, but what my question is that is CRON already set up, do I just go right ahead and use CRON or do I need to set it up first?

  • How to Access User Directory shared by Apache on OS X Mountain Lion?

    - by schluchc
    When trying to access the local user web page on localhost/~username, I get a "403 Forbidden". The system web page in /Library/WebServer/Documents is accessible on localhost/ though, so I assume Apache is working fine. I know that this problem has been discussed several times, also on superuser. I implemented and checked all I could find, but I still couldn't solve the problem and would be glad if someone had a suggestion for this particular case: sudo apachectl -t returns Syntax OK. I have a username.conf file in /etc/apache2/users/: <Directory "/Users/username/Sites/"> Options Indexes MultiViews FollowSymLinks AllowOverride AuthConfig Limit Order allow,deny Allow from all </Directory> as proposed here [SuperUser] and in several other tutorials. The permissions of the username.conf file are -rw-r--r-- root wheel, as they should be. The httpd.conf is unchanged and therefore contains the line Include /private/etc/apache2/extra/httpd-userdir.conf. That file in turn contains UserDir Sites Include /private/etc/apache2/users/*.conf <IfModule bonjour_module> RegisterUserSite customized-users </IfModule> So the httpd*.conf files should be ok. The permissions of /Users/username/Sites is drwxr-xr-x 10 username staff and -rw-r--r--@ 1 username staff for the index.html. In the error log I simply get a [Sun Nov 25 22:14:32 2012] [error] [client 127.0.0.1] (13)Permission denied: access to /~username/ denied. And yes, after each change I did the sudo apachectl restart. Any help no how to solve the problem or how to further analyze it would be highly appreciated!

    Hi, I'm new to iptables, and i've been trying to put together a firewall which purpose is to protect a web server. The below rules are the ones i've put together so far, and i would like to hear if the rules makes sense - and wether i've left out anything essential? In addition to port 80, i also need to have port 3306 (mysql) and 22 (ssh) open for external connections. Any feedback is highly appreciated! #!/bin/sh # Clear all existing rules. iptables -F # ACCEPT connections for loopback network connection, 127.0.0.1. iptables -A INPUT -i lo -j ACCEPT # ALLOW established traffic iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # DROP packets that are NEW but does not have the SYN but set. iptables -A INPUT -p tcp ! --syn -m state --state NEW -j DROP # DROP fragmented packets, as there is no way to tell the source and destination ports of such a packet. iptables -A INPUT -f -j DROP # DROP packets with all tcp flags set (XMAS packets). iptables -A INPUT -p tcp --tcp-flags ALL ALL -j DROP # DROP packets with no tcp flags set (NULL packets). iptables -A INPUT -p tcp --tcp-flags ALL NONE -j DROP # ALLOW ssh traffic (and prevent against DoS attacks) iptables -A INPUT -p tcp --dport ssh -m limit --limit 1/s -j ACCEPT # ALLOW http traffic (and prevent against DoS attacks) iptables -A INPUT -p tcp --dport http -m limit --limit 5/s -j ACCEPT # ALLOW mysql traffic (and prevent against DoS attacks) iptables -A INPUT -p tcp --dport mysql -m limit --limit 25/s -j ACCEPT # DROP any other traffic. iptables -A INPUT -j DROP

  • Client cannot access my IIS7 web server

    - by Soccerwiz
    I have a Windows 2008 web server on running IIS 7 with about 25 websites. One of those sites is an SaaS application that is accessed constantly throughout the day. However, one particular client keeps getting blocked from my server. They will be using the service, and then all of a sudden they cannot access the program, or any other site on the server. The entire office of 4 users is blocked from accessing anything on the web server. A trace route reveals they get all the way to the server before they are blocked. However, they can access a linux server that is a different VM with a different IP on the same physical server. Also, when they are blocked from their office, they can still access the site from their mobile phone or local Starbucks. They can also occasionally reset the router and gain access to the web server again as they are on a dynamic IP address. I checked IIS and allow all IPs to access the server. There is nothing in the logs the says anything about a user being banned. I really have no idea what is causing this? Could it be a virus on their end? I have even moved the SaaS to a completely new server in a different location, and they were working fine for about a month, and then the problem started occurring again. Are there any hidden blacklists in IIS? Or is it a routing issue on their end?

  • Trying to Set up SMTP Server on WIndows Server 2012

    - by datc
    I'm working on a website, and I need to test the functionality of sending email messages from ASP.NET, something like this: Dim msg As New MailMessage("email1", "email2") msg.Subject = "Subject"<br> msg.IsBodyHtml = True<br> msg.Body = "Click <a href='site'>here</a>." Dim client As SmtpClient = New SmtpClient() client.Host = "My-Server"<br> client.Port = 25<br> client.DeliveryMethod = SmtpDeliveryMethod.Network<br> client.Send(msg) This is running from a Windows 8 workstation. I've installed SMTP server on my Windows Server 2012 machine. The mail shows up in the mailroot/Queue folder and sits there, eventually getting deposited into Badmail. Now I have AT&T U-verse at home, and a few devices connected to the gateway, including let's call it "My-Server." When I run SmtpDiag from say, datc@... to [email protected] I get SOA serial number match passed, Local DNS (99-135-60-233.lightspeed.bcvloh.sbcglobal.net) & Remote DNS (hotmail.com) tests *not* passed, and ultimately, Connecting to the server failed. Error: 10060. Failed to submit mail to mx2.hotmail.com error. When I set My-Server's IP to static and equal to the external IP, 99.135.60.233, and again run SmtpDiag, I get SOA, Local DNS, and Remote DNS tests passed, but the same 10060 error. Same for yahoo.com, gmail.com, and so forth. Is it my ISP's job to fix this? Some PTR record missing somewhere? Is it at all possible to have a home-based SMTP server? All I want is to test my email code. Perhaps, my IP address is just not "trusted" somehow. Thanks.

  • Why do I have redundant routing in Windows 7?

    - by Mark
    I'm trying to better understand my routing tables. My routing table is: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 1. 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.151 25 2. 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 3. 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 4. 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 5. 192.168.1.0 255.255.255.0 On-link 192.168.1.151 281 6. 192.168.1.151 255.255.255.255 On-link 192.168.1.151 281 7. 192.168.1.255 255.255.255.255 On-link 192.168.1.151 281 8. 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 9. 224.0.0.0 240.0.0.0 On-link 192.168.1.151 281 10. 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 11. 255.255.255.255 255.255.255.255 On-link 192.168.1.151 281 =========================================================================== Most of those entries make sense to me, but a few confuse me: 2 and 3 seem redundant, as do 2 and 4. Why not just 2? 5 and 6 seem redundant, as do 5 and 7. Why not just 5? I'm trying to grok routing tables and this bit is still confusing me.

  • Low-profile, PCI Express, x1 video card with VGA-out?

    - by Dandy
    I just bought an Acer Aspire EasyStore H340 system (http://us.acer.com/acer/productv.do?LanguageISOCtxParam=en&kcond61e.c2att101=54825&sp=page16e&ctx2.c2att1=25&link=ln438e&CountryISOCtxParam=US&ctx1g.c2att92=450&ctx1.att21k=1&CRC=936243954) It comes with Windows Home Server, which I don't particularly care for (too dumbed down for my liking)--I bought the box mainly for the form factor, and intend to install Server 2008 on it and have it run as a small domain controller. The geniuses at Acer however went out of their way to ensure you can only run Home Server--you can only connect to it via the Home Server Connector software, as it has no video-out whatsoever (so essentially, there's no way to even get into the BIOS). It only has a low-profile, PCI Express x1 slot. It turns out to be way harder than I thought to locate a video card that both has an x1 connector, and is low-profile (I'd really rather not snip the bracket at the back just so it'll fit the case). I know they're out there, and I've seen one with Display Port outputs, but I don't have a monitor with this connection. So to reiterate, it needs to be: - x1 connector - low profile - VGA out (though DVI would be okay; I have some spare adapters) Can anyone recommend anything at all?

  • Certain websites redirect to 127.0.0.1. How do I fix this?

    - by Dian
    Facebook and Youtube in particular. Tried nslookup the address shows as 127.0.0.1. Checked the HOSTS file, it's fine. Ran Malwarebytes' Anti-Malware (didn't find any problems) and SpyBot Search and Destroy (found 1 problem). (Not sure if the Spybot made this improvement) now pinging youtube shows the correct address (74.125.71.91) but the browser still says: Connection to 127.0.0.1 Failed The system returned: (111) Connection refused Tried ipconfig /flushdns but there are no changes. Switched to another user but the results are the same. hosts file: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names.

  • Ubuntu: Memory Leak

    - by Keener
    I'm having trouble finding from where this memory leak is occurring. I'm running Ubuntu 8.04 LTS on a Dell XPS M1530. I have 3GB of ram and I'm finding after about an hour or so of use top shows me 2GBs+ used. The strange thing is when I add up the memory percentages by PID either from top or ps aux I find that I should only be using about 20-25% of my available ram. What brought this to my attention was I've begun running vmware server again. Now, obviously the ram usage spikes when I load a virtual machine, but the memory VMware is using does not account for the memory usage I'm seeing via top or free. Stopping vmware server releases the memory which was allocated to it, but I'm still unable to find where this RAM is being used. After a complete reboot, of course, the memory is fine, but very quickly it climbs to 60-80% usage with the processes only appearing to account for a third of that. Any ideas where I should look for more information on what this could be?

  • Disaster Recovery Standby Server

    - by user64300
    Hi, I work for a small business with 25 users and 2 servers. 1 server is the DC running Windows Server 2003/Exchange 2003. We want a reliable disaster recovery strategy for this server without having to spend a lot of money. We take regular backups but I have been advised that only an identical server will allow them to be restored easily. I'm trying to come up with a solution that means we don't have to buy two servers at twice the cost everytime we upgrade. I'm toying with the idea of upgrading our DC more frequently (say every 3 years) and then using the old server as the recovery server (temporarily - until we can source a replacement server). However, I won't know whether the backups will restore on the old server until I try it! We're planning to upgrade to Server 2008R2 in the near future so I'm hoping the backup tools will give me some success in restoring to different hardware (or perhaps I can use hyper-v if not). So what I am wondering is whether it is a idea to use old hardware as a disaster recovery strategy (providing we regular test it obviously!).
