All printing now uses the same 15 1.1 jtc SVR4 based printing model: lp, lpstat, cancel. This implies SunOS 4.1 16 1.1 jtc or later on a Sun. The printing hasn't been properly tested on SVR4, 17 1.1 jtc since my SVR4 system is a bit quirky, but authentication via shadow 18 1.1 jtc passwords works fine. 19 1.1 jtc 20 1.1 jtc The Makefile supplied will build either SunOS 4.1 or SVR4 versions; 21 1.1 jtc however you will need to tweak a couple of definitions. See the 22 1.1 jtc Makefile for details. 23 1.1 jtc 24 1.1 jtc For this round, I have frozen the rpcgen'd code and modified it by hand 25 1.1 jtc to get around a few rpcgen deficiencies. If in doubt, you can take the 26 1.1 jtc pcnfsd.x file included here off to a separate directory, rpcgen everything 27 1.1 jtc up and diff against the versions given here. 28 1.1 jtc 29 1.1 jtc You should also be sure to read the man page. I haven't tried [nt]roff'ing 30 1.1 jtc this anywhere outside SunOS, so let me know if there are any quirks. 31 1.1 jtc Note especially the /etc/pcnfsd.conf configuration model. 32 1.1 jtc 33 1.1 jtc Standard disclaimers. Read the source for more of the same. 34 1.1 jtc 35 1.1 jtc Geoff Arnold (Geoff.Arnold (a] Sun.COM) 36 1.1 jtc May 2, 1991 37 1.1 jtc 38 1.1 jtc ---------------------------------------------------------------------- 39 1.1 jtc This is the first major spin since the version I posted in May. 40 1.1 jtc Changes are described in the SCCS deltas, but anyone analysing 41 1.1 jtc or porting this should watch for the following: 42 1.1 jtc 43 1.1 jtc - Lots of SVR4 stuff. Look at the Makefile and common.h; you will 44 1.1 jtc need to make sure that SVR4 is defined to build a version for SVR4. 45 1.1 jtc - Fixed a major bug whereby aliased printers (a.k.a. virtual printers) 46 1.1 jtc didn't show up in the printer list. 47 1.1 jtc - Since some commands (especially lpq) can hang up forever if, say, 48 1.1 jtc the host of a remote printer is down, the su_popen mechanism now 49 1.1 jtc includes a watchdog timer. I HAVE NOT HAD A CHANCE TO TEST THIS 50 1.4 andvar LOGIC ON SVR4 YET! The code was derived from the System V compatibility 51 1.1 jtc section of the AnswerBook, so it _should_ be OK, but I can't wait to 52 1.1 jtc test it before posting this. 53 1.1 jtc - I've mades lots of lint-suggested improvements. It doesn't lint 54 1.1 jtc 100% cleanly yet, but it's a lot better. 55 1.1 jtc - The client testbed has been tightened up a bit and the reporting 56 1.1 jtc is somewhat clearer. Please run it. 57 1.1 jtc 58 1.1 jtc Feedback is solicited. 59 1.1 jtc 60 1.1 jtc Geoff Arnold (Geoff.Arnold (a] Sun.COM) 61 1.1 jtc July 24, 1991 62 1.1 jtc 63 1.1 jtc ---------------------------------------------------------------------------- 64 1.1 jtc 65 1.1 jtc This version includes support for TCP as well as UDP, both in the 66 1.1 jtc server and in the test client. Some of the calls can have long 67 1.1 jtc responses, in which case TCP is the preferred transport. 68 1.1 jtc 69 1.1 jtc Jon Dreyer 70 1.1 jtc January 28, 1992 71 1.1 jtc 72 1.1 jtc ---------------------------------------------------------------------------- 73 1.1 jtc 74 1.1 jtc This release incorporates minor bug fixes occasioned by internal testing 75 1.1 jtc against preliminary versions of PC-NFS subsystems which actually use the 76 1.1 jtc V2 protocol features. It also addresses a security hole which was identified: 77 1.1 jtc see the comment in pcnfsd_print.c for details. This is the version 78 1.1 jtc of the daemon which we expect to send out for beta testing. 79 1.1 jtc 80 1.1 jtc Geoff Arnold 81 1.1 jtc November 16, 1991 82 1.1 jtc 83 1.1 jtc ---------------------------------------------------------------------------- 84 1.1 jtc 85 1.1 jtc Several people pointed out that if I was going to fix the security 86 1.1 jtc hole, I should *REALLY* fix it. So this revision checks every argument 87 1.1 jtc for every shell metacharacter. This means that if your print subsystem 88 1.1 jtc allows such characters in printer names, print job id's, user names, 89 1.1 jtc etc. you're going to have to relax the restrictions or tighten up 90 1.1 jtc elsewhere. The routine "suspicious()" in pcnfsd_print.c is the starting 91 1.1 jtc point for this. 92 1.1 jtc 93 1.1 jtc Geoff Arnold 94 1.1 jtc November 21, 1991 95 1.1 jtc 96 1.1 jtc ---------------------------------------------------------------------------- 97 1.1 jtc 98 1.1 jtc This version includes one more tweak on the previous security fix, plus 99 1.1 jtc a fix for the "user shell" security hole. 100 1.1 jtc 101 1.1 jtc Geoff Arnold 102 1.1 jtc December 17, 1991 103 1.1 jtc 104 1.1 jtc ---------------------------------------------------------------------------- 105 1.1 jtc 106 1.1 jtc Fix a stupid bug - the secondary groups array wasn't static, so it 107 1.1 jtc got overwritten, resulting in the corruption of some GIDs. 108 1.1 jtc 109 1.1 jtc Geoff Arnold 110 1.1 jtc December 18, 1991 111
