Unix (all-caps UNIX for the trademark) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.


Evp evp – high-level cryptographic functions SYNOPSIS #include (openssl/evp.h) DESCRIPTION The EVP library provides a high-level interface to cryptographic func- tions. EVP_Seal… and EVP_Open… provide public key encryption and decryp- tion to implement digital “envelopes”. The EVP_Sign… and EVP_Verify… functions implement digital signa- tures. Symmetric encryption is available with the EVP_Encrypt… functions. The EVP_Digest… functions […]


Dynamic_pager dynamic_pager — dynamic pager external storage manager SYNOPSIS dynamic_pager [-E] [-F filename] [-S filesize] [-H high-water-trigger] [-L low-water-trigger] [-P priority] DESCRIPTION The dynamic_pager daemon manages a pool of external swap files which the kernel uses to support demand paging. This pool is expanded with new swap files as load on the system increases, and […]


Distnoted distnoted — distributed notification server SYNOPSIS distnoted DESCRIPTION distnoted provides distributed notifications services. There are no configuration options to distnoted. Users should not run distnoted manually. EOF


Diskarbitrationd diskarbitrationd — disk arbitration daemon SYNOPSIS diskarbitrationd [-d] DESCRIPTION diskarbitrationd listens for connections from clients, notifies clients of the appearance of disks and filesystems, and governs the mounting of filesystems and the claiming of disks amongst clients. diskarbitrationd is accessed via the Disk Arbitration framework. Options: -d Report detailed information in /var/log/diskarbitrationd.log. This option […]


Cupsd cupsd.conf – server configuration file for cups DESCRIPTION The cupsd.conf file configures the CUPS scheduler, cupsd(8). It is normally located in the /etc/cups directory. Each line in the file can be a configuration directive, a blank line, or a comment. Comment lines start with the # character. The configura- tion directives are intentionally similar […]


Crypt crypt, setkey, encrypt, des_setkey, des_cipher, — DES encryption SYNOPSIS #include char *crypt(const char *key, const char *setting); void setkey(char *key); void encrypt(char *block, int flag); int des_setkey(const char *key); int des_cipher(const char *in, char *out, long salt, int count); DESCRIPTION The crypt() function performs password encryption, based on the NBS Data Encryption Standard (DES). […]


Configd configd — System Configuration Daemon SYNOPSIS configd [-bdv] [-B bundleID] [-V bundleID] [-t bundle-path] DESCRIPTION The configd daemon is responsible for many configuration aspects of the local system. configd maintains data reflecting the desired and current state of the system, provides notifications to applications when this data changes, and hosts a number of configuration […]


Cksum cksum – checksum and count the bytes in a file SYNOPSIS cksum [–help] [–version] [file…] DESCRIPTION This manual page documents the GNU version of cksum. cksum computes a cyclic redundancy check (CRC) for each named file, or the standard input if none are given or when a file named `-‘ is given. It prints […]


Charset charset – Set an ACM for use in one of the G0/G1 charset slots. SYNOPSIS charset [-v] G0|G1 [cp437|iso01|vt100|user|] DESCRIPTION The linux console has 2 slots for charsets, labeled G0 and G1. charset changes the slot in use by the current VT to either G0 or G1, and fills the slot either with one […]


Blowfish blowfish, BF_set_key, BF_encrypt, BF_decrypt, BF_ecb_encrypt, BF_cbc_encrypt, BF_cfb64_encrypt, BF_ofb64_encrypt, BF_options – Blow- fish encryption SYNOPSIS #include (openssl/blowfish.h) void BF_set_key(BF_KEY *key, int len, const unsigned char *data); void BF_ecb_encrypt(const unsigned char *in, unsigned char *out, BF_KEY *key, int enc); void BF_cbc_encrypt(const unsigned char *in, unsigned char *out, long length, BF_KEY *schedule, unsigned char *ivec, int enc); […]
