Linux Socket Programming provides a accomplished dialogue of all proper themes together with: writing courses suitable with either web Protocol model four (IPv4) and IPv6, uncooked sockets, person Datagram Protocol (UDP), broadcasting /multicasting, server internals, and extra, plus a piece masking Posix threads.It offers thorough assurance of programming with the TCP, UDP, and IP protocols, in addition to lower-level uncooked sockets. The myriad of functionality calls, information constructions, and techniques linked to the APIs are defined with well-chosen diagrams and tables.

When useful Unix defense was once first released greater than a decade in the past, it turned an immediate vintage. filled with information regarding host defense, it kept many a Unix method administrator from catastrophe. the second one version additional much-needed net protection insurance and doubled the scale of the unique quantity. The 3rd version is a finished replace of this very hot publication - a better half for the Unix/Linux method administrator who must safe his or her organization's process, networks, and internet presence in an more and more opposed world.
Focusing at the 4 hottest Unix editions today--Solaris, Mac OS X, Linux, and FreeBSD--this ebook includes new details on PAM (Pluggable Authentication Modules), LDAP, SMB/Samba, anti-theft applied sciences, embedded platforms, instant and computing device concerns, forensics, intrusion detection, chroot jails, cell scanners and firewalls, digital and cryptographic filesystems, WebNFS, kernel safety degrees, outsourcing, criminal concerns, new net protocols and cryptographic algorithms, and masses more.
Practical Unix & web defense comprises six parts:
desktop protection fundamentals: creation to safety difficulties and suggestions, Unix background and lineage, and the significance of safety rules as a easy part of approach safety.
protection construction blocks: basics of Unix passwords, clients, teams, the Unix filesystem, cryptography, actual safeguard, and body of workers safeguard.
community protection: an in depth examine modem and dialup defense, TCP/IP, securing person community prone, Sun's RPC, a variety of host and community authentication platforms (e. g. , NIS, NIS+, and Kerberos), NFS and different filesystems, and the significance of safe programming.
safe operations: maintaining so far in today's altering defense global, backups, protecting opposed to assaults, appearing integrity administration, and auditing.
dealing with safety incidents: researching a break-in, facing programmed threats and denial of carrier assaults, and criminal points of machine defense.
Appendixes: a entire safeguard list and an in depth bibliography of paper and digital references for additional examining and research.
Packed with a thousand pages of priceless textual content, scripts, checklists, suggestions, and warnings, this 3rd version continues to be the definitive reference for Unix directors and someone who cares approximately maintaining their structures and information from today's threats.
Info know-how is an more and more huge think about felony court cases. In instances huge and small, from the U. S. Government's antitrust swimsuit opposed to Microsoft company, to civil complaints filed over the failure of a community, to felony situations during which the authenticity of digital proof is wondered, the testimony of a technical professional is key.
This is often the only such a lot priceless desktop ebook i've got learn. i've been dabbling with establishing a server for months. trendy servers make the most of such a lot of diverse applied sciences (HTTP, SQL, SSH, SSL, FTP, DNS, Mail) that simply collecting the data to establish server with standard positive factors is a giant job - particularly whether it is no longer your actual activity.
After a starting evaluate of the background of OpenSolaris, its open-source licensing, and the neighborhood improvement version, this e-book then is going directly to spotlight the facets of OpenSolaris that fluctuate from extra time-honored working platforms. you are going to how you can develop into an influence person of OpenSolaris by way of maximizing the talents of complex positive aspects like Dtrace, the fault administration structure, ZFS, the carrier administration facility, and Zones.

Extra info for Linux socket programming
These options include routing information, timestamps, security measures, routing record, and route alerts. This field can be up to 40 bytes long. Because some of the options are system dependent, you are unlikely to ever touch these options directly. data Field Your message goes here and can include up to 65,535 bytes (minus 60 bytes, the maximum size of the header). The data section includes any header information that the higher protocols need. For example, ICMP requires 4 bytes, UDP requires 8 bytes, and TCP requires 20–60 bytes.
All networks place a maximum frame size so those large messages don't dominate the network. Keep in mind that the routing host may still carve up, or fragment, large messages that go through a constricted network. Each protocol has a different likelihood of fragmentation. Since reassembling fragmented messages is part of IP, the reassembly may be transparent to the higher protocols. Certain circumstances, however, may require the packet's wholeness. This is particularly important for network performance.
Anything that can affect public or private health/life. For example, life signs and vital signs from medical equipment and missile launch commands. Critical—Important and reliable data. Data that if out of sequence or faulty can cause harm to property or security. For example, financial transactions, credit cards, PIN numbers, digital signatures, electronic money, trade secrets, virus scanner updates, and product updates. Important—Data that requires proper functionality. Any loss can cause malfunction.
