Cannot logon to Windows XP without activation beyond 30 days

Well, guys this is the most common, issue faced with system administrators who forgot to activate XP within 30 days of its installation.

In my case, the issue was P2V of Windows XP physical machine and due to drastic hardware architecture changes, Windows XP loses its activation and requires re-activation.
See my previous blog post

With the instructions i was successfully able to first configure network settings and then activated the OS.
Here is the brief step by step instructions:

  • Turn on your computer and login to your account. You get a message telling you that you need to activate your product, Click Yes and the Activate Windows screen will load.
  • Now press the windows key + U and Microsoft Narrator should pop up. Click OK for the little disclaimer Narrator gives you and behind it will be the Narrator option screen. In the top left of the Narrator option screen, you’ll see a little computer icon, click it and a drop-down menu will appear.
  • Click on About Narrator. On the next pop-up, click the link Microsoft Web site. You now have access to Internet Explorer!!! Whether you have an internet connection at the time or not, it doesn’t matter, we aren’t actually trying to get online.

Now we are going to access your desktop and Start bar. In the address bar, type: C:\WINDOWS\explorer.exe and press enter.

VOILA! You have access to your entire computer just like you normally would! Don’t close Narrator though, because windows tends to realize what you’re doing and reset back to the Activation screen. It’s not bullet-proof, sometimes my computer will reset back to the activation screen, but you can just do the same thing again as many times as you want!

XVA won’t start after successful import

I converted a physical machine (Windows XP) successfully & imported to my XenServer with XenConvert. The import appears to be successful. However, when I start the machine, all I get is a black console screen with the following info:

Citrix XenServer
http://www.citrix.com
cirrus-compatible VGA is detected

Processor 1: Xen(R) Virtual CPU
XS Virtual IDE Controller Hard Drive (73GB)
XS Virtual ATAPI-4 CD-Rom/DVD-Rom

Boot device: Hard Drive – success.

Some licensed legacy application was running on this machine and we needed to eliminate any physical PC in Datacenter.
Else there was no need to import XP rather would have built new one.
Well after repeated reboot no success with the VM, searching the forum someone suggested to fix boot sector with Windows XP repair disk.
The iso of existing XP-SP3 didn’t offer repair screen since the original install didn’t match the iso file.

SystemRescueCd-x86-2.5.1 iso came handy, booted from this gentoo based linux distro and fixed the boot sector with “ntfsfix”.
Disconnected the iso and voila the VM booted successfully.

So far only the vm booted successfully, but any geek would guess that due to HAL changes between the physical and virtual, XP ends up in re-activation process.
Without network the VM cannot connect to internet.. how will i fix this.
look out for next blog post… 🙂

How To Whitelist Hosts/IP Addresses In Postfix

If you are administrating a mail server and use blacklists to block spam (like in this article: How To Block Spam Before It Enters The Server (Postfix)), you probably know this problem: from time to time your customers complain that they cannot receive emails from certain freemailers. Most often this happens because a freemailer was abused to send out spam and therefore got blacklisted. This short guide shows how you can whitelist such a mail server in Postfix to make your customers happy again.

I do not issue any guarantee that this will work for you!

If a blacklisted server tries to send mail to your server, you should find something like this in your mail log:

SMTP error from remote mail server after RCPT TO:<bla@example.com>: host mail.example.com [4.3.2.1]: 554 5.7.1 Service unavailable; Client host [1.2.3.4] blocked using dnsbl.sorbs.net; Currently Sending Spam See: http://www.sorbs.net/lookup.shtml?1.2.3.4

In this example, the mail server 1.2.3.4 is blacklisted and therefore blocked.

To whitelist that server, create the file /etc/postfix/rbl_override where you list all IP addresses or host names (one per line!) that you want to whitelist:

vi /etc/postfix/rbl_override

1.2.3.4 OK
1.2.3.5 OK
mail.freemailer.tld OK

After you’ve created/modified that file, you must run

postmap /etc/postfix/rbl_override

Next open /etc/postfix/main.cf and search for the smtpd_recipient_restrictions parameter. Add check_client_access hash:/etc/postfix/rbl_override to that parameter, after reject_unauth_destination, but before the first blacklist.

So if smtpd_recipient_restrictions looks like this now…

vi /etc/postfix/main.cf

[...] smtpd_recipient_restrictions = reject_invalid_hostname,<br />                               reject_unauth_pipelining,                               permit_mynetworks,                               permit_sasl_authenticated,                               reject_unauth_destination,                               reject_rbl_client multi.uribl.com,                               reject_rbl_client dsn.rfc-ignorant.org,                               reject_rbl_client dul.dnsbl.sorbs.net,                               reject_rbl_client list.dsbl.org,                               reject_rbl_client sbl-xbl.spamhaus.org,                               reject_rbl_client bl.spamcop.net,                               reject_rbl_client dnsbl.sorbs.net,                               reject_rbl_client cbl.abuseat.org,                               reject_rbl_client ix.dnsbl.manitu.net,                               reject_rbl_client combined.rbl.msrbl.net,                               reject_rbl_client rabl.nuclearelephant.com,                               permit [...]

… modify it so that it looks as follows:

[...] smtpd_recipient_restrictions = reject_invalid_hostname,                               reject_unauth_pipelining,                               permit_mynetworks,                               permit_sasl_authenticated,                               reject_unauth_destination,                               check_client_access hash:/etc/postfix/rbl_override,                               reject_rbl_client multi.uribl.com,                               reject_rbl_client dsn.rfc-ignorant.org,                               reject_rbl_client dul.dnsbl.sorbs.net,                               reject_rbl_client list.dsbl.org,                               reject_rbl_client sbl-xbl.spamhaus.org,                               reject_rbl_client bl.spamcop.net,                               reject_rbl_client dnsbl.sorbs.net,                               reject_rbl_client cbl.abuseat.org,                               reject_rbl_client ix.dnsbl.manitu.net,                               reject_rbl_client combined.rbl.msrbl.net,                               reject_rbl_client rabl.nuclearelephant.com,                               permit <br />[...]

That’s it! Restart Postfix, and you’re done:

/etc/init.d/postfix restart

Bluecoat Proxy – Site restriction

Hey, sysadmin’s

Those administering Bluecoat Proxy SG appliance and has encountered that allowing certain sites/url for selected users does not work properly.

This is due to that the main site accessing  different subsites/urls in background for providing the associated services.

All those sites/urls have to be taken into consideration while providing access to particular site.

Well lets take for example you give access to only hotmail/live.com and its not working properly then in that case the following all urls needs to be permitted for flawless working:

hotmail site      

.accountservices.passport.net
.secure.shared.live.com 
.live.com     

and for facebook here are the URL which includes games apps too.

facebook site

.facebook.com
.facebook.net
.fbcdn.net 
.akamaihd.net        
.zgncdn.com

iPhone & Gmail account

If You have iPhone and are not able to add your gmail account or if authentication fails, then following condition applies:

You have turned on two steps verification for gmail account then you need to authorize your iPhone device. When this is done a password DIFFERENT from your google account password is autogenerated by Google. It is this autogenerated password that you need to enter into your iphone. So here’s what worked.

Log into your Google account through https://www.google.com/accounts/Login and go to Personal Settings > Security > Authorizing applications & sites and revoke your previous access to iphone (if any)

Then create it again and when the password is generated in the ‘Generate new application-specific password box’, use that new generated password in your Gmail Account Information on the iPhone below your email address.
