README revision 1.1
1 1.1 jtc 2 1.1 jtc July 1995 - Ported to NetBSD by Gordon Ross <gwr (a] netbsd.org> 3 1.1 jtc 4 1.1 jtc Note: to build clnt.pcnfsd use the command: 5 1.1 jtc make -f Makefile.clnt 6 1.1 jtc 7 1.1 jtc Text of original README file from Sun follows: 8 1.1 jtc ---------------------------------------------------------------------- 9 1.1 jtc 10 1.1 jtc This is version @(#)README 1.6 1/28/92 of the pcnfsd README file. 11 1.1 jtc ---------------------------------------------------------------------- 12 1.1 jtc This is the second cut at PCNFSD v2. All printing now uses the same 13 1.1 jtc SVR4 based printing model: lp, lpstat, cancel. This implies SunOS 4.1 14 1.1 jtc or later on a Sun. The printing hasn't been properly tested on SVR4, 15 1.1 jtc since my SVR4 system is a bit quirky, but authentication via shadow 16 1.1 jtc passwords works fine. 17 1.1 jtc 18 1.1 jtc The Makefile supplied will build either SunOS 4.1 or SVR4 versions; 19 1.1 jtc however you will need to tweak a couple of definitions. See the 20 1.1 jtc Makefile for details. 21 1.1 jtc 22 1.1 jtc For this round, I have frozen the rpcgen'd code and modified it by hand 23 1.1 jtc to get around a few rpcgen deficiencies. If in doubt, you can take the 24 1.1 jtc pcnfsd.x file included here off to a separate directory, rpcgen everything 25 1.1 jtc up and diff against the versions given here. 26 1.1 jtc 27 1.1 jtc You should also be sure to read the man page. I haven't tried [nt]roff'ing 28 1.1 jtc this anywhere outside SunOS, so let me know if there are any quirks. 29 1.1 jtc Note especially the /etc/pcnfsd.conf configuration model. 30 1.1 jtc 31 1.1 jtc Standard disclaimers. Read the source for more of the same. 32 1.1 jtc 33 1.1 jtc Geoff Arnold (Geoff.Arnold (a] Sun.COM) 34 1.1 jtc May 2, 1991 35 1.1 jtc 36 1.1 jtc ---------------------------------------------------------------------- 37 1.1 jtc This is the first major spin since the version I posted in May. 38 1.1 jtc Changes are described in the SCCS deltas, but anyone analysing 39 1.1 jtc or porting this should watch for the following: 40 1.1 jtc 41 1.1 jtc - Lots of SVR4 stuff. Look at the Makefile and common.h; you will 42 1.1 jtc need to make sure that SVR4 is defined to build a version for SVR4. 43 1.1 jtc - Fixed a major bug whereby aliased printers (a.k.a. virtual printers) 44 1.1 jtc didn't show up in the printer list. 45 1.1 jtc - Since some commands (especially lpq) can hang up forever if, say, 46 1.1 jtc the host of a remote printer is down, the su_popen mechanism now 47 1.1 jtc includes a watchdog timer. I HAVE NOT HAD A CHANCE TO TEST THIS 48 1.1 jtc LOGIC ON SVR4 YET! The code was derived from the System V compatiility 49 1.1 jtc section of the AnswerBook, so it _should_ be OK, but I can't wait to 50 1.1 jtc test it before posting this. 51 1.1 jtc - I've mades lots of lint-suggested improvements. It doesn't lint 52 1.1 jtc 100% cleanly yet, but it's a lot better. 53 1.1 jtc - The client testbed has been tightened up a bit and the reporting 54 1.1 jtc is somewhat clearer. Please run it. 55 1.1 jtc 56 1.1 jtc Feedback is solicited. 57 1.1 jtc 58 1.1 jtc Geoff Arnold (Geoff.Arnold (a] Sun.COM) 59 1.1 jtc July 24, 1991 60 1.1 jtc 61 1.1 jtc ---------------------------------------------------------------------------- 62 1.1 jtc 63 1.1 jtc This version includes support for TCP as well as UDP, both in the 64 1.1 jtc server and in the test client. Some of the calls can have long 65 1.1 jtc responses, in which case TCP is the preferred transport. 66 1.1 jtc 67 1.1 jtc Jon Dreyer 68 1.1 jtc January 28, 1992 69 1.1 jtc 70 1.1 jtc ---------------------------------------------------------------------------- 71 1.1 jtc 72 1.1 jtc This release incorporates minor bug fixes occasioned by internal testing 73 1.1 jtc against preliminary versions of PC-NFS subsystems which actually use the 74 1.1 jtc V2 protocol features. It also addresses a security hole which was identified: 75 1.1 jtc see the comment in pcnfsd_print.c for details. This is the version 76 1.1 jtc of the daemon which we expect to send out for beta testing. 77 1.1 jtc 78 1.1 jtc Geoff Arnold 79 1.1 jtc November 16, 1991 80 1.1 jtc 81 1.1 jtc ---------------------------------------------------------------------------- 82 1.1 jtc 83 1.1 jtc Several people pointed out that if I was going to fix the security 84 1.1 jtc hole, I should *REALLY* fix it. So this revision checks every argument 85 1.1 jtc for every shell metacharacter. This means that if your print subsystem 86 1.1 jtc allows such characters in printer names, print job id's, user names, 87 1.1 jtc etc. you're going to have to relax the restrictions or tighten up 88 1.1 jtc elsewhere. The routine "suspicious()" in pcnfsd_print.c is the starting 89 1.1 jtc point for this. 90 1.1 jtc 91 1.1 jtc Geoff Arnold 92 1.1 jtc November 21, 1991 93 1.1 jtc 94 1.1 jtc ---------------------------------------------------------------------------- 95 1.1 jtc 96 1.1 jtc This version includes one more tweak on the previous security fix, plus 97 1.1 jtc a fix for the "user shell" security hole. 98 1.1 jtc 99 1.1 jtc Geoff Arnold 100 1.1 jtc December 17, 1991 101 1.1 jtc 102 1.1 jtc ---------------------------------------------------------------------------- 103 1.1 jtc 104 1.1 jtc Fix a stupid bug - the secondary groups array wasn't static, so it 105 1.1 jtc got overwritten, resulting in the corruption of some GIDs. 106 1.1 jtc 107 1.1 jtc Geoff Arnold 108 1.1 jtc December 18, 1991 109
