NAME¶

kgrantpty - konsole uses this to securely open a slave pty

SYNOPSIS¶

kgrantpty [OPTION] [FILE]

DESCRIPTION¶

kgrantpty is only intended to be used internally by konsole to open a slave pty securely. It performs a setuid chmod and chown on the slave pty device. Eavesdropping is prevented with the usage of a file handle as an argument. KPty automatically calls this tool, and it is not intended to be called from the command line.

OPTIONS¶

--grant

grant secure setuid root chmod and chown to the file descriptor

--revoke

revoke the secure setuid root chmod and chown from the file descriptor

SECURITY¶

kgrantpty must be used as setuid root.

SEE ALSO¶

ttyname(3), forkpty(3), tty(4), pty(7)
