Newsgroups: comp.sources.unix From: brnstnd@nyu.edu (Dan Bernstein) Subject: v25i127: Generalized interface to pseudo-tty devices, Part01/09 Sender: unix-sources-moderator@pa.dec.com Approved: vixie@pa.dec.com Submitted-By: brnstnd@nyu.edu (Dan Bernstein) Posting-Number: Volume 25, Issue 127 Archive-Name: pty4/part01 [ What can I say? It slices, it dices, it washes dishes, it walks the dog. It "just works", meaning that if you follow the directions you'll get a working package without any pulling of hair or gnashing of teeth or other standard porting activities. Here's BLURB, to convince you that it's worth unpacking and installing. --vix ] pty is meant as the sole interface between pseudo-terminals and the rest of the system. Rich Salz said of pty 3.0: ``This is the Ginsu knife (it slices, it dices, it never rusts) that Dan has been talking about in comp.unix.wizards/internals for some time now. It is a mind-blower.'' But I just couldn't leave well enough alone, so here's pty 4.0, a vastly improved rewrite of the entire package. A taste of what it has to offer: * Improved security - pty 3.0 offered tty security ahead of its time--- several months afterwards, Sun released a ``critical'' security patch with essentially the same security tests. Now pty 4.0 offers proven security. Although you can install and use the package without privileges, system administrators can install pty 4.0 so that it _guarantees_ that nobody else has access to your tty. I'm offering a cash reward for anyone who can subvert these guarantees. * Session management - If you run your shell under pty, and the connection is hung up, you can log in again and reconnect. The session management model is extremely simple---it has just three primitives--- yet powerful enough to accomplish tricky tasks, such as recording the output from a process after the process has started. A paper in the package, ``An introduction to session management,'' leads even novice users through competent use of session management commands. * Automatic installation - pty 4.0 comes with a completely automated configure/compile/install/verify-configuration setup. It will configure itself properly for most popular systems without human input. * Modularity - When I say that pty is meant as the sole interface to pseudo-terminals, I mean it! pty doesn't get in the way of direct, efficient pseudo-terminal I/O. So you can use it as a component of other programs which add input line editing, virtual screen support, or other fancy features. pty handles just one job, and handles it so cleanly that you'll never have to duplicate pseudo-terminal code in another program. * Free utilities - pty 4.0 comes with even more useful utilities than pty 3.0. It includes ten improved clones of standard utilities, notably a version of ``script'' which makes a proper utmp entry; and thirty new tools ranging from administrative helpers to ``tscript'', which records an interactive session _including the timing between characters_. Power users will appreciate ``nobuf'', which uses pty to transparently turn off stdio buffering in any program. * Free libraries - The pty package comes with several of my favorite libraries: env, fmt, getopt, radixsort, ralloc, scan, sigdfl, sigsched, sod, timer, username. You can use all of these for your own programs. * POSIX support - pty 4.0 works without trouble under popular POSIX/BSD systems, including Ultrix 4.1 and SunOS 4.1.1. All the job control features have been adapted to work with POSIX job control. pty should also be included with BSD 4.4. * Detailed documentation - Let your worries about incomplete program documentation be over. The pty package includes more than five thousand lines of documentation: forty quick-reference man pages; papers on controlling ttys, job control, session management, and user log files; extensive notes on pty internals and porting issues; and more. Okay, enough hype. What's pty good for? Once upon a time nethack would, if you were lucky, produce characters with both a ring of polymorph and a ring of polymorph control. I wanted to run nethack inside a script which would keep rerolling characters until it saw that combination. (Playing by the rules was never my forte.) Unfortunately, nethack didn't like having its input and output redirected. So I wrote the first versions of pty. ``pty nethack'' worked just like ``nethack'' but could be invoked in the middle of a pipe inside a script. As the years went by, pty became somewhat more powerful and flexible, but its basic function has always remained the same: to run programs, especially ``interactive'' programs, under a pseudo-tty. Despite this single-minded attitude, pty has wormed its way into the solutions to dozens of problems, ranging from buffer control to automating telnet scripts to making rlogind secure. Pseudo-terminal code seems to spring up everywhere; pty is your weapon to slash that code to a single line. Enjoy! ---Dan Bernstein, brnstnd@nyu.edu #! /bin/sh # This is a shell archive.

Check the bottom of README for any notes relevant to X your system. X2. Make and run CHECKCONF. Edit config/* if necessary. If you don't have X privileges, make sure to change config/ptybin.h, config/ptydir.h, and X config/sess*.h. If you make any changes to config/*.h, you may want X to make and run CHECKCONF again. (If you don't have privileges, you X may also want to change flagxonlysecure = 0 to flagxonlysecure = -1 X in ptymain.c line 36; this will eliminate a warning message each time X you use pty.) X3. Make. X4. Make INSTALL. (This doesn't actually install pty; it only makes the X INSTALL program, which you run in step 7.) X5. If you have privileges, and you don't have a tty group (group 4), X make one. X6. If you have privileges, and you want to run pty as its own uid rather X than root, make a pty uid. X7. As root, run INSTALL, or ``INSTALL root'' if pty should run as root. X If you don't have privileges, run INSTALL anyway, and don't worry X about the error messages. Tricks: yes skip | ./INSTALL to see all the X steps of installation without executing any; yes ok | ./INSTALL to do X complete installation without having to confirm each step. X8. Change /dev/tty* to be owned by pty if (1) pty isn't running as root X but (2) you still want to take advantage of pty's security features. X (If you want, you can chown only some of the ttys---tty[t-z]*, say. X Then pty will stick to those. In this case you should probably edit X config/ptyext.h to match.) Also change /dev/pty* to be owner pty and X mode 0600 if you want to prevent denial of service attacks; keep in X mind that this will stop valid non-root programs from opening ttys, X and that it will not close the dozens of other denial of service X attacks on your machine. (You may want to chmod and chown only a few X of the ptys, to keep them free for pty just in case.) X9. If you want, invoke wtmprotate, sessrotate, or sclogrotate from your X daily, weekly, or monthly cron scripts. (wtmprotate may already be X handled by your vendor's scripts.) Also invoke utmpinit, sessnowinit, X and scnowinit from /etc/rc.local. Don't worry about these if you X don't have privileges. X10. Run checkptys. If you want, arrange to have checkptys run X periodically by cron. X11. If you want to make sure that pty works, look through TESTS and see X whether your setup works the same way. X12.

This means that any attempt to open your terminal, including through /dev/tty, will fail. X X.B write is affected by X.B exclon, but X.B talk is not. This feature has made X.B exclon a popular tool for people who prefer the X.B talk style of communication. X To unreserve your terminal, use X.B excloff. It is polite to do this at the end of a session, though it is automatic when the terminal is closed. X.SH AUTHOR I hesitate to claim authorship for a one-statement program.
