The Sun ONE Directory Server is a powerful, distributed directory server that is designed to manage an enterprise-wide directory of users and resources.
This scalable directory service can be used for intranet applications, extranets with trading partners, and e-commerce applications to reach customers over the Internet. Administrators use the Console to grant access rights, manage databases, configure the directory, and replicate the data to multiple directory servers. Server ncftpls options trading client configuration information is available in the System Administration Guide: See also the iPlanet Directory Server 5.
This collection includes the following books:. Naming service support has been enhanced in ncftpls options trading Solaris 9 release. Changes include the following:. A ncftpls options trading robust security model — Supports strong authentication and TLS-encrypted sessions. A client's proxy credentials are no longer stored in a client's profile on the directory server.
For further information, ncftpls options trading the System Administration Guide: The IPsec security framework has been enhanced in the Solaris 9 release to enable secure IPv6 datagrams between machines. The inetd networking command has been enhanced to support the monitoring and filtering of incoming requests for network ncftpls options trading.
The server can be configured to log the client host name of incoming requests and ncftpls options trading enhance network security. The inetd command uses the same mechanism that is used by the Tcp-wrappers 7. For information about Tcp-wrappers 7.

Originally developed by Washington University, WU-ftpd ncftpls options trading widely used for the distribution of bulk data over the Internet.
WU-ftpd is the preferred standard for large FTP sites. The following new features are available in sendmail version 8. Per RFCsendmail now listens for submissions on portncftpls options trading feature that was added but not mentioned, in version 8. Also, because sendmail is no longer setuid rootonly root can run newaliases. Resource Management and Network Services.
The chapters ncftpls options trading mail services provide overview information and procedures for setting up and modifying your mail service. Also provided are procedures for troubleshooting, some background information, and details about the new features. With minimal modifications, any web server can communicate through the sockets interface. Finally, the ncab2clf ncftpls options trading has been enhanced. New options enable you to skip records before ncftpls options trading selected date and to process a particular number of records when converting log files.
IP network multipathing provides your system with recovery from single-point failures with network adapters and increased traffic throughput. The alternate adapter must be connected to the same IP link. This process ensures uninterrupted access to the network. When you have multiple network adapters connected to the same IP link, you achieve increased traffic throughput by spreading the traffic across multiple network adapters. This process has no impact on existing IP users.
A failed NIC is removed from the system by using dynamic reconfiguration. A reboot occurs prior to reinsertion of a functioning NIC.
In these circumstances, the system attempts, but fails, to plumb an interface for the missing NIC. Link-down notifications enable the IP multipathing daemon to detect physical link failures faster. When a network interface is started, the IP multipathing daemon attempts to enable link-up and link-down notifications from the network interface driver. A link-down notification is generated when the interface detects the loss of the physical link to the network.
A link-up notification is generated when the physical link is restored. The driver must support this feature in order for the notification procedure to work. Mobile Internet Protocol Mobile IP enables the transfer of information to and from mobile computers, such as laptop and wireless communications. The mobile computer can change its ncftpls options trading to a foreign network and still access and communicate with and through the mobile computer's home network.
A reverse tunnel can be set up from the mobile node's care-of address to the home agent. This reverse tunnel ensures a topologically correct source address for the IP data packet. By using reverse tunnels, system administrators can also assign private addresses to mobile ncftpls options trading.
Dynamically created interfaces are interfaces that are configured after the mipagent daemon starts. You can now configure the foreign agent implementation to send advertisements over dynamically created interfaces. You can also enable or disable some unsolicited advertisements over the advertising interfaces. The updated version is BIND version 8.
The addition of the ndc command and the dnskeygen command — The ndc command is used to start, stop, or reconfigure in. See the dig 1M man page for instructions on how to gather information from the DNS servers. See ncftpls options trading the ndc 1M and dnskeygen 1M man pages.

The File Transfer Protocol FTP is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server. The first FTP client applications were command-line programs developed before operating systems had graphical user interfaces ncftpls options trading, and are still shipped with most WindowsUnix ncftpls options trading, and Linux operating systems.
FTP may run in active or passive mode, which determines how the data connection is established. Both modes were updated in September to support IPv6. Further changes were introduced to the passive mode at that time, updating it to extended passive mode.
The server responds over the control connection with three-digit status codes in ASCII with an optional text message. For example, "" or " OK" means that the last command was successful. The numbers represent the code for the response and the optional text represents a human-readable explanation or request e. While transferring data over the network, four data representations can be used: For text files, different format control and record structure options are provided.
These features were designed to facilitate files containing Telnet or ASA. Data transfer can be done in any of three modes: This mode was described in an Internet Draftbut not standardized. FTP login uses normal username and ncftpls options trading scheme for granting access. Although users are commonly asked to send ncftpls options trading email address instead of a password,  no verification is actually performed on the supplied data.
FTP normally transfers data by having the server connect back to the client, after the PORT command is sent by the client. This is problematic for both NATs and firewalls, which do not allow connections from the Internet towards internal hosts. There are two approaches to solve this problem. HTTP essentially fixes the bugs in FTP that made it inconvenient to use for many small ephemeral transfers as are typical in web pages. FTP has a stateful control connection which maintains a current working directory and other flags, and each transfer requires a secondary connection through which the data are transferred.
In "passive" mode this secondary ncftpls options trading is from client to server, whereas in the default "active" mode this connection is from server to client. This apparent role reversal when in active mode, and random port numbers for all transfers, is why firewalls and NAT gateways have such a hard time with FTP. HTTP is stateless and multiplexes control and data over a single ncftpls options trading from client to server on well-known port numbers, which ncftpls options trading passes through NAT gateways and is simple for firewalls to manage.
Setting up an FTP control connection is quite slow due to the round-trip delays of sending all of the required commands and awaiting responses, so it is customary to bring up a ncftpls options trading connection and hold it open for multiple file transfers rather than drop and re-establish the session afresh each time. In contrast, HTTP originally dropped the connection after each transfer because doing so was so cheap. While HTTP has subsequently gained the ability to reuse the TCP connection for multiple transfers, the conceptual model is still of independent requests rather than a session.
When FTP is transferring over the data connection, the control connection is idle. If the transfer takes too long, the firewall or NAT may decide that the control connection is dead and stop tracking it, effectively breaking the connection and confusing the download.
The single HTTP connection is only idle between requests and it is normal and expected for such connections to be dropped after a time-out. For example, the URL ftp: More details on specifying a username and password may be found in the browsers' documentation e. By default, most web browsers use passive PASV mode, which more easily traverses end-user firewalls. Some variation has existed in how different browsers treat path resolution in ncftpls options trading where there is ncftpls options trading non-root home directory for a user.
FTP was not designed to be a secure protocol, and has many security weaknesses. FTP does not encrypt its traffic; all transmissions are in clear text, and usernames, passwords, commands and data can be read by anyone able to perform packet capture sniffing on the network. With many SSH clients, attempting to set up a tunnel for ncftpls options trading control channel the initial client-to-server connection on port 21 will protect only that channel; when data is transferred, the FTP software at either end sets up new TCP connections data channels and thus have no confidentiality or integrity protection.
Otherwise, it is necessary for the SSH client software to have specific knowledge of the FTP protocol, to monitor and rewrite FTP control channel messages and autonomously open new packet forwardings for FTP data channels. Software packages that support ncftpls options trading mode include:. The server has the option of allowing or denying connections that do not request TLS. It was specified to use different ports than plain FTP. Unlike FTP, it encrypts both commands and data, preventing passwords and sensitive information from being transmitted openly over the network.
It cannot interoperate with FTP software. One of its ncftpls options trading uses is in the early stages of booting from a local area networkbecause TFTP is very simple to implement. TFTP ncftpls options trading security and most of the advanced features offered by more robust file transfer protocols such as File Transfer Protocol. It runs through portand often receives the initialism of SFTP. It has a command set of 11 commands and support three types of data transmission: ASCIIbinary and continuous.
For systems ncftpls options trading a word size that is a multiple of 8 bits, the implementation of binary and continuous is the same. The protocol also supports login with user ID and password, hierarchical folders and file management including renamedeleteuploaddownloaddownload with ncftpls options tradingand download with append. The reply code is a three-digit value. The third digit of the reply code is used to provide additional detail for each of the categories defined by the second digit.
