check last failed login attempts ubuntu

grep "Failed password" /var/log/auth.log

 cat /var/log/auth.log | grep "Failed password"

In CentOS or RHEL, the failed SSH sessions are recorded in /var/log/secure file. Issue the above command against this log file to identify failed SSH logins.

egrep "Failed|Failure" /var/log/auth.log

A slightly modified version of the above command to display failed SSH logins in CentOS or RHEL is as follows.

# grep "Failed" /var/log/secure
# grep "authentication failure" /var/log/secure

enctype= multipart/form-data

HTML forms provide three methods of encoding.

application/x-www-form-urlencoded (the default)
multipart/form-data
text/plain

Work was being done on adding application/json, but that has been abandoned.

(Other encodings are possible with HTTP requests generated using other means than an HTML form submission. JSON is a common format for use with web services and some still use SOAP.)

The specifics of the formats don’t matter to most developers. The important points are:

Never use text/plain.

When you are writing client-side code:

use multipart/form-data when your form includes any <input type="file"> elements
otherwise you can use multipart/form-data or application/x-www-form-urlencoded but application/x-www-form-urlencoded will be more efficient

When you are writing server-side code:

Use a prewritten form handling library

Most (such as Perl’s CGI->param or the one exposed by PHP’s $_POST superglobal) will take care of the differences for you. Don’t bother trying to parse the raw input received by the server.

Sometimes you will find a library that can’t handle both formats. Node.js’s most popular library for handling form data is body-parser which cannot handle multipart requests (but has documentation that recommends some alternatives which can).

If you are writing (or debugging) a library for parsing or generating the raw data, then you need to start worrying about the format. You might also want to know about it for interest’s sake.

application/x-www-form-urlencoded is more or less the same as a query string on the end of the URL.

multipart/form-data is significantly more complicated but it allows entire files to be included in the data. An example of the result can be found in the HTML 4 specification.
