The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

I got a requirement from my client that he wishes to encrypt/ password protect some of the documents, before sending over to another user in another regional office.

By not writing the password into the email body.

How can the user in another regional office knows the password to decrypt/ open the protected documents?

What approach should be adopted? Is there any standard/ algorithm I can refer to? But we prefer not to use any 3rd party software/ utility.

Thank you.

Very bizarre issue. Details:

1. A customer on fibre-optic high speed Internet (via ISP-provided router) cannot connect to nor ping a mail server at web-hosting.com.
2. I arrived there with my own laptop, tried both LAN and wifi, and also could not ping the mail server.
3. I remoted into 3 other computers from his house, and from those remote computers, pinged the mail server just fine. These two other computers are in the same city as my customer. Two use the same ISP as my customer.
4. The ISP apparently logged in and checked his router - they say all is fine, and they have no idea why this would be happening.
5. Except for the inability to reach the mail server, the connection is completely fine - can get anywhere on the Internet, etc.

I seem to recall having an issue like this years ago, and it had something to do with routing at the ISP, but cannot remember any details.

Has anyone ever encountered anything like this?  I'm going there in two days to do a full reset of his router, but not confident this will be the cure.

Whenever I login to my college LAN network using my credentials on UBUNTU 14.04 (Dell laptop), it shows that maximum login limit is reached.

I am using internet wih my ID and Password, and suddenly it happens, when I am using only one device at a time.

It happens only in UBUNTU and everything works fine when I am on WINDOWS. This limit persists for a long duration (an hour or so).

Plz tell a solution, what can I do? {any command in ubuntu terminal, change DNS, VPN, or anything else}

Device: ASA 5510

Over the last couple of weeks I have noticed that my main (outside) connection has no traffic at certain parts of the day.
ie around 9/10 am until about 1130 am/12 pm there is no traffic on this interface. Our backup interface kicks in until traffic continues on the main interface. During the down time if i plug a laptop and put in static IP, I am able to get out to the internet. I have talked to the ISP they are saying its on my end.

Any suggestions on what could cause this?
