Is this server alive?
Returns the eigenvalues in an array
Symmetric Householder reduction to tridiagonal form.
Symmetric tridiagonal QL algorithm.
Wakes up the first thread in line waiting for this lock.
Returns the status (STAT command). pathname - when stat is invoked with pathname as a parameter it acts like
list but alot faster and over the same tcp session.
Creates a new Net::HTTP
object, then additionally opens the TCP connection and HTTP
session.
Arguments are the following:
hostname or IP address of the server
port of the server
address of proxy
port of proxy
user of proxy
pass of proxy
optional hash
opt sets following values by its accessor. The keys are ca_file
, ca_path
, cert, cert_store
, ciphers, close_on_empty_response
, key, open_timeout
, read_timeout
, ssl_timeout
, ssl_version
, use_ssl, verify_callback
, verify_depth
and verify_mode. If you set :use_ssl as true, you can use https and default value of verify_mode
is set as OpenSSL::SSL::VERIFY_PEER.
If the optional block is given, the newly created Net::HTTP
object is passed to it and closed when the block finishes. In this case, the return value of this method is the return value of the block. If no block is given, the return value of this method is the newly created Net::HTTP
object itself, and the caller is responsible for closing it upon completion using the finish() method.
Returns true if the HTTP
session has been started.
Opens a TCP connection and HTTP
session.
When this method is called with a block, it passes the Net::HTTP
object to the block, and closes the TCP connection and HTTP
session after the block has been executed.
When called with a block, it returns the return value of the block; otherwise, it returns self.
Raises an HTTP error if the response is not 2xx (success).
Sends a STARTTLS command to start TLS session.
Sends the GETQUOTAROOT command along with the specified mailbox
. This command is generally available to both admin and user. If this mailbox exists, it returns an array containing objects of type Net::IMAP::MailboxQuotaRoot
and Net::IMAP::MailboxQuota
.
Sends the GETQUOTA command along with specified mailbox
. If this mailbox exists, then an array containing a Net::IMAP::MailboxQuota
object is returned. This command is generally only available to server admin.
Sends a SETQUOTA command along with the specified mailbox
and quota
. If quota
is nil, then quota
will be unset for that mailbox. Typically one needs to be logged in as a server admin for this to work. The IMAP
quota commands are described in [RFC-2087].
Sends the SETACL command along with mailbox
, user
and the rights
that user is to have on that mailbox. If rights
is nil, then that user will be stripped of any rights to that mailbox. The IMAP
ACL
commands are described in [RFC-2086].
Send the GETACL command along with a specified mailbox
. If this mailbox exists, an array containing objects of Net::IMAP::MailboxACLItem
will be returned.
Sends a STATUS command, and returns the status of the indicated mailbox
. attr
is a list of one or more attributes whose statuses are to be requested. Supported attributes include:
MESSAGES:: the number of messages in the mailbox. RECENT:: the number of recent messages in the mailbox. UNSEEN:: the number of unseen messages in the mailbox.
The return value is a hash of attributes. For example:
p imap.status("inbox", ["MESSAGES", "RECENT"]) #=> {"RECENT"=>0, "MESSAGES"=>44}
A Net::IMAP::NoResponseError
is raised if status values for mailbox
cannot be returned; for instance, because it does not exist.
Creates a new POP3
object and open the connection. Equivalent to
Net::POP3.new(address, port, isapop).start(account, password)
If block
is provided, yields the newly-opened POP3
object to it, and automatically closes it at the end of the session.
Net::POP3.start(addr, port, account, password) do |pop| pop.each_mail do |m| file.write m.pop m.delete end end
true
if the POP3
session has started.
Starts a POP3
session.
When called with block, gives a POP3
object to the block and closes the session after block call finishes.
This method raises a POPAuthenticationError
if authentication fails.
Returns truth value if this object uses STARTTLS. If this object always uses STARTTLS, returns :always. If this object uses STARTTLS when the server support TLS, returns :auto.
Creates a new Net::SMTP
object and connects to the server.
This method is equivalent to:
Net::SMTP.new(address, port).start(helo_domain, account, password, authtype)
Net::SMTP.start('your.smtp.server') do |smtp| smtp.send_message msgstr, 'from@example.com', ['dest@example.com'] end
If called with a block, the newly-opened Net::SMTP
object is yielded to the block, and automatically closed when the block finishes. If called without a block, the newly-opened Net::SMTP
object is returned to the caller, and it is the caller’s responsibility to close it when finished.
address
is the hostname or ip address of your smtp server.
port
is the port to connect to; it defaults to port 25.
helo
is the HELO domain provided by the client to the server (see overview comments); it defaults to ‘localhost’.
The remaining arguments are used for SMTP
authentication, if required or desired. user
is the account name; secret
is your password or other authentication token; and authtype
is the authentication type, one of :plain, :login, or :cram_md5. See the discussion of SMTP
Authentication in the overview notes.
This method may raise:
true
if the SMTP
session has been started.
