2015-07-26T02:26:00.000-07:00

When you click on the "Customize" button, it logs you out of WordPress. It says "Your session has expired. Please log-in again."

When you log in again, it immediately logs you out.Same issue also comes up when trying to "Live Preview" themes.

Solution
In wordpress Go to settings > general menu > "site address (URL)" set to "www.domain.com" if you have redirected your naked domain to www in your DNS settings.

Hopefully this works for someone.

2014-07-06T08:11:00.000-07:00

If you are getting "The page you are looking for is temporarily unavailable. Please try again later." while browsing your website after updating server update,mainly PHP5-FPM update.

Here is the solution.

I had the same error after updating my server and found the above error.

What solved the issue was uncomment the following lines in /etc/php5/fpm/pool.d/www.conf and restart php5-fpm

Hope  this will help.

How to restrict lotus notes users to send a mail from diffrent internet address by changing internet address in thier lotus notes location document settings

2014-01-03T00:53:00.002-08:00

Lotus notes user puts somebody else's Internet address in Location and sends e-mail throught Internet ? Then, you cannot check by who was it sent actually.

To prevent lotus users to send a mail from someone`s e-mail address,please do below settings.
Go to server`s configuration documents------MIME-----Advanced----Advanced outbound messaging tab.

Put "InetFrom" to Notes items to be removed from headers field without quotes, which holds the internet address as specified in the location document. When those fields are missing, the router will do a lookup in the Domino Directory to find the senders' correct internet address. If the person doc doesn't have an internet address, the router will construct an internet address based on the conversion options specified in the global domain document.

Change your DNS settings to avoid 9 June 2012 DNSChanger issue

2012-07-08T23:41:00.000-07:00

As you all must be seening in the media, all rouge servers would be shut down by the US Govt today i.e. 9 July 2012. Hence all machines infected with the malacious bugs which are forcing the machine to use the rouge DNS will need to change the DNS settings in order to keep browsing the internet.
You have an option to use either of the FREE RECURSIVE DNS services provided by Symantec, Google, UltraDNS, OpenDNS etc. A list of the services and the IP addresses of their DNS servrrs are mentioned below.

Open DNS
Primary DNS Server – 208.67.222.222
Secondary DNS Server – 208.67.220.220
Google DNS
Primary DNS Server – 8.8.8.8
Secondary DNS Server – 8.8.4.4
DNS Advantage by Neustar UltraDNS
Primary DNS Server – 156.154.70.1
Secondary DNS Server – 156.154.71.1
Norton DNS
Primary DNS Server – 198.153.192.60
Secondary DNS Server – 198.153.194.60
Please follow the steps mentioned in the following link to change the DNS for Windows or Apple OS. Ideally though a little technical changing the DNS globally on your Router is considered the best practice for a Home or SoHo user.

How to Install and Configure Caching-Only Bind DNS Server on Ubuntu Linux

2012-01-10T20:19:00.000-08:00

A caching server helps when a host name is asked for many times by local clients. For example, google.com, neerajsain.com and nsain.in are all requested many times by most users. By caching the dns query your dns server can respond with the results quickly and without having to use any external bandwidth.
Bind has the ability to locally cache dns queries as well as serve authoritative name resolution. By using a locally cached dns server you can significantly speed up local dns resolution of commonly resolved names.

How to Install Bind DNS Server.
1.#sudo apt-get install bind9
2.Edit "named.conf.options" located at "/etc/bind/named.conf.options"

// Your local network and any IP address range you want to allow to query the DNS server
 acl internal { any; };

 options {
         directory "/var/cache/bind";

         // Disable all zone transfer requests
         allow-transfer {"none";};

         // Closed DNS; permit only allowed IP addresses specified above to issue queries
         allow-query { internal; };

         // If there is a firewall between you and nameservers you want
         // to talk to, you might need to uncomment the query-source
         // directive below.  Previous versions of BIND always asked
         // questions using port 53, but BIND 8.1 and later use an unprivileged
         // port by default.

         // query-source address * port 53;

         // If your ISP provided one or more IP addresses for stable
         // nameservers, you probably want to use them as forwarders.
         // Uncomment the following block, and insert the addresses replacing
         // the all-0's placeholder.
 
         // forwarders {
         //      0.0.0.0;
         // };

         auth-nxdomain no;    # conform to RFC1035
         listen-on-v6 { any; };
 };

3.Now you need to edit "named.conf" file.
#sudo vi /etc/bind/named.conf

Then, change the file so it looks like the following :

// This is the primary configuration file for the BIND DNS server named.
//
// Please read /usr/share/doc/bind9/README.Debian.gz for information on the
// structure of BIND configuration files in Debian, *BEFORE* you customize
// this configuration file.
//
// If you are just adding zones, please do that in /etc/bind/named.conf.local

include "/etc/bind/named.conf.options";

// prime the server with knowledge of the root servers
zone "." {
         type hint;
         file "/etc/bind/db.root";
};

// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912

zone "localhost" {
         type master;
         file "/etc/bind/db.local";
         allow-update{none;};
};

zone "127.in-addr.arpa" {
         type master;
         file "/etc/bind/db.127";
         allow-update{none;};
};

zone "0.in-addr.arpa" {
         type master;
         file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
         type master;
         file "/etc/bind/db.255";
};

4.Now restart you bind server.
#sudo /etc/init.d/bind9 restart
5.How to test DNS server.

You'll notice the query time is much faster the second time around; that's because the first time, the results were cached on the DNS server! Feel free to try this with several domains, they should all return similar speed-ups for query time!

Now you have a local DNS Server.You can now point all your internet servers(

Proxy or ISA) to use your local DNS server for internet DNS query.

What is ODS(on disk structure) in IBM Lotus Domino

2011-03-04T04:12:00.000-08:00

ODS in Lotus Notes Domino is stands for ON Disk Structure.

By Default:
Domino 6, 7, 8 and 8.5 have the default ODS version of 43.
The maximum version for Domino 6 and 7 is 43.
The maximum version for Domino 8 is 48.
The maximum version for Domino 8.5 is 51.

The execution control list or ECL

2011-03-04T03:53:00.000-08:00

An execution control list (ECL) to set up workstation data security. An ECL protects user workstations against unknown or suspect sources, and can be configured to limit the action of any active content that does run on workstations. The ECL determines whether the signer of the code is allowed to run the code on a given workstation, and defines the access that the code has to various workstation functions.
There are two kinds of ECLs: the Administration ECL, which resides in the Domino Directory (NAMES.NSF), and the workstation ECL, which is stored in the user's Personal Address Book (NAMES.NSF). The Administration ECL is the template for all workstation ECLs. The workstation ECL is created when the Notes client is first installed. The Setup program copies the administration ECL from the Domino Directory to the Notes client to create the workstation ECL.

NSD in Lotus Notes and Domino

2011-01-17T08:27:00.000-08:00

NSD a program that comes with both the Notes Client and the Domino Server. It takes control in the event of a crash, and writes a diagnostic log that is frequently very helpful in figuring out what went wrong. If you ever experience a crash in Notes or Domino, nsd.exe will automatically come online and do its thing. You'll find the resulting crash log in the IBM_TECHNICAL_SUPPORT sub-folder in your Notes/Domino data directory.

How to read NSD FILES.

Look for the word fatal, underneath it you will find the current thread. You can kind of determine what the server/client was doing at the moment of the crash.

For example, here's an except from an NSD

############################################################
### FATAL THREAD 02/47 [ nHTTP:0b08:0d53]

So, in this example, HTTP caused the server crash and launched NSD.

What is Roaming User and How to Register it in Lotus Notes

2010-07-21T03:34:00.000-07:00

Users who access IBM Lotus Notes from more than one Notes client can access their customized settings and personal information automatically from any Notes client in the domain.

When a roaming user logs on from any Notes client their ID file is accessed from the local file system, their Contacts application or from the Domino ID vault according to how the administrator configured the user account. The user's roaming-enabled files include contacts, bookmarks, notebook or journal, feeds subscriptions.

These files are replicated locally from the user's roaming server. Any changes the user makes in these files replicates back to the roaming server. This enables the roaming user to have a consistent experience from any Notes client.

Note-Switching user IDs is not supported for roaming users. Notes client users enabled for roaming should not switch to another user ID by using the File - Security - Switch ID menu options nor should they choose another Location document that switches to another user ID. Switching user IDs can cause unintentional user downgrade from roaming. If you use multiple user IDs on the same computer, roaming is not supported.

Note--Roaming user IDs are not supported with Notes Single Logon (NSL).

Data for roaming users replicates between the user's client system and a roaming server, where their roamed files, including their contacts, bookmarks, notebook or journal, feeds subscriptions, and roaming data which stores roamed Eclipse™ plug-in data and settings.

How do you change the replica ID of a Lotus Notes/Lotus Domino database?

2010-07-21T02:59:00.000-07:00

Changing the replica ID of a database.

There are two ways to change a replica ID:

Option 1 - Create a new copy of the database using the Notes client.
From the File menu, choose Database --> New Copy. This creates a random new replica ID for the new database.

Option 2 - Use the ANTRID tool. "ANTRID" or "A Notes Tool for Replica IDs" allows Domino administrators to change the replica ID of Notes databases.
Download ANTRID from http://www.rprsystems.com/index.html

How Mail flow in Lotus Notes and Domino

2010-07-21T02:49:00.000-07:00

NRPC Mail Flow

Notes client,which is used to create the message and transfer the message to the Domino Server.

The message is transferred via NRPC to the Domino Server .

The message is written to the Mail Box database on the server.

Note: This database(mailbox) ACL -Default- access is set to Depositor so

users can “deposit” mail but cannot read any of the messages waiting for delivery.

By default the message is also saved in the sender’s Mail database on the user’s Home/Mail server for later reference.

The Router server task uses the Domino Directory to determine where to transfer the message. If the destination Domino Domain is:-

>the same as the server’s, the Router looks up the recipient’s Person document in the Domino Directory to find the recipient’s Home/Mail server name.

>in another Domino Domain, the Router looks up the Connection document to a Domino Server in that other Domain.

If the message is destined for a user on the same Home/Mail Server as the sender, the Router delivers it immediately. Otherwise, the

Router copies the message out of the local Mail Box and writes it to the remote Mail Box database on the target Domino Server using the NRPC protocol.

If successful, the Router then deletes the message from the local Mail Box database.

The Router server task uses the Domino Directory to determine where to transfer or deliver the message. If the recipient Mail database is on:

> the same server, the Router looks up the recipient’s Person document to find the Mail database file name

> another server in the same Domino Named Network, the Router immediately transfers the message to that server via NRPC

> another server in a different Domino Named Network, the Router looks up the Connection document to a Domino Server in that

other Domino Named Network and transfers the message via NRPC.

Whether for message transfer or delivery, the Router stamps its name and the current date/time that it handled the message.

The Router checks any user mail rules that may delete or modify the message. If not, the Router copies the message out of its local Mail Box and writes it to the user’s Mail database using the NRPC protocol.

The Router deletes the message from its local Mail Box database.Notes is used to read the message from the server copy of the Mail database. This is just like reading any other Domino database.The message is retained in the user’s Mail database on theserver until explicitly deleted by the user (or archived to another database via an agent running in the Mail database).

Mail-In Database

2010-07-21T02:18:00.000-07:00

A database that is set up to receive mail, without the mail being added to a person's mail file.

The mail-in database can then be accessed by one person, or by multiple people, who have access to read the database.

For example, if you want multiple users on a mailing list to read specific mail, that mail can be sent to a mail-in database instead of sending it to numerous individual users.

Those users can then open the database and review the mail that has been sent to that database.

If a database is designed to receive mail, you must create a Mail-In Database document in the Domino Directory.

This document must exist in the Domino Directory of every server that stores a replica of the database. The database cannot receive mail until you create this document.

When replicating Mail-in databases to servers in another Lotus Domino domain, create a matching Mail-in database document in the Domino Directory of the target server.

Creating a Mail-In Database document for a new database

From the People & Groups tab of the Domino Administrator, choose the Mail-In Databases view.

Click Add Mail-In database and enter the following information.

Mail-in name...

The entry for this database in the Domino Directory.

Users and applications use this name to send documents to the database.

Internet message storage..

No preference (default)

Prefers MIME

Prefers Notes Rich Text.

Internet address..

SMTP address in the format mailfile@organization.domain.

Complete this field if you want Internet users to be able to send messages to the database.

Encrypt Incoming Mail..

Yes or no according to your preference.

Mail sent to the mail-in database is encrypted with the Lotus Notes certified public key entered in the next field.

Domain..

Domino domain of the server where the database resides.

Server..

The fully-distinguished hierarchical name of the server where the database resides; for example, Server1/Sales/Acme

Filename...

The path and filename of the database relative to the Domino Directory.

For example, if the database named MAILIN.NSF is in the MAIL directory of the DATA directory, enter MAIL\MAILIN.NSF.

Owners..

Fully distinguished hierarchical name of users allowed to modify this document.

Administrators...

Users or groups who can edit this document.

Allow foreign directory synchronization..

Choose one of these:

Yes -- Allows entry to be exchanged with foreign directories -- for example, a cc:Mail® directory -- so that users on the other system can look up the mail-in database in the cc:Mail post office directory and send mail to it.

No -- Does not allow the entry to be exchanged with foreign directories.

Notes certified public key...

The certified public key to use when encrypting mail sent to this database.

To copy a certified public key from the Domino Directory to this field, click "Get Certificates" and choose a name.

Internet Certificate...

This field displays the Internet Certificate if one exists.

If there is no Internet Certificate for this mail-in database, the field displays the message "Not Available."

Issuer name...

The field is populated only if the Internet Certificate field displays an Internet Certificate.
