After negotiation is complete, it has to set up the required network interfaces and routes, so that the connection is run by the kernel. pppd terminates a PPP link when: too many frames with invalid frame check sequence (FCS) field have been received; the link is considered "idle" (if configured) another program or the peer requests link ...
A TCP reset attack, also known as a forged TCP reset or spoofed TCP reset, is a way to terminate a TCP connection by sending a forged TCP reset packet. This tampering technique can be used by a firewall or abused by a malicious attacker to interrupt Internet connections.
n2n, an open source Layer 2 over Layer 3 VPN application which uses a peer-to-peer architecture for network membership and routing Tinc , Ethernet/IPv4/ IPv6 over TCP/UDP; encrypted, compressed VTun , Ethernet/IP/serial/ Unix pipe over TCP; encrypted, compressed, traffic-shaping
In contrast, the Control-D causes the Unix terminal driver to signal the EOF condition, which is not a character, while the byte has no special meaning if actually read or written from a file or terminal. In Unix, the end-of-file character (by default EOT) causes the terminal driver to make available all characters in its input buffer ...
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
The Linux daemons sysrqd [12] and tcpconsole [13] provide a method of accessing SysRq features over a TCP connection after authenticating with a plain-text password. The hangwatch [ 14 ] daemon will invoke pre-configured SysRq triggers when system load average exceeds a certain threshold.
The other pseudo-device, the slave, emulates a hardware serial port device, [1] and is used by terminal-oriented programs such as shells (e.g. bash) as a processes to read/write data back from/to master endpoint. [1] PTYs are similar to bidirectional pipes. [3]: 1388 Devpts is a Linux kernel virtual file system containing pseudoterminal devices.
X.25 is an ITU-T standard protocol suite for packet-switched data communication in wide area networks (WAN). It was originally defined by the International Telegraph and Telephone Consultative Committee (CCITT, now ITU-T) in a series of drafts and finalized in a publication known as The Orange Book in 1976.
