7 | README.solaris - Perl version 5 on Solaris systems | |
8 | ||
9 | =head1 DESCRIPTION | |
10 | ||
11 | This document describes various features of Sun's Solaris operating system | |
12 | that will affect how Perl version 5 (hereafter just perl) is | |
13 | compiled and/or runs. Some issues relating to the older SunOS 4.x are | |
14 | also discussed, though they may be out of date. | |
15 | ||
16 | For the most part, everything should just work. | |
17 | ||
18 | Starting with Solaris 8, perl5.00503 (or higher) is supplied with the | |
19 | operating system, so you might not even need to build a newer version | |
20 | of perl at all. The Sun-supplied version is installed in /usr/perl5 | |
2a5ccb22 LC |
21 | with /usr/bin/perl pointing to /usr/perl5/bin/perl. Do not disturb |
22 | that installation unless you really know what you are doing. If you | |
23 | remove the perl supplied with the OS, there is a good chance you will | |
24 | render some bits of your system inoperable. If you wish to install a | |
25 | newer version of perl, install it under a different prefix from | |
26 | /usr/perl5. Common prefixes to use are /usr/local and /opt/perl. | |
27 | ||
28 | You may wish to put your version of perl in the PATH of all users by | |
b29a8fb9 | 29 | changing the link /usr/bin/perl. This is OK, as all Perl scripts |
2a5ccb22 | 30 | shipped with Solaris use /usr/perl5/bin/perl. |

32 | =head2 Solaris Version Numbers. | |
33 | ||
34 | For consistency with common usage, perl's Configure script performs | |
35 | some minor manipulations on the operating system name and version | |
36 | number as reported by uname. Here's a partial translation table: | |
37 | ||
38 | Sun: perl's Configure: | |
39 | uname uname -r Name osname osvers | |
2a5ccb22 | 40 | SunOS 4.1.3 Solaris 1.1 sunos 4.1.3 |
d420ca49 AD |
41 | SunOS 5.6 Solaris 2.6 solaris 2.6 |
42 | SunOS 5.8 Solaris 8 solaris 2.8 | |

a83b6f46 | 76 | =head2 File Extraction Problems on Solaris. |
d420ca49 AD |
77 | |
78 | Be sure to use a tar program compiled under Solaris (not SunOS 4.x) | |
79 | to extract the perl-5.x.x.tar.gz file. Do not use GNU tar compiled | |
80 | for SunOS4 on Solaris. (GNU tar compiled for Solaris should be fine.) | |
81 | When you run SunOS4 binaries on Solaris, the run-time system magically | |
82 | alters pathnames matching m#lib/locale# so that when tar tries to create | |
83 | lib/locale.pm, a file named lib/oldlocale.pm gets created instead. | |
5511f325 | 84 | If you found this advice too late and used a SunOS4-compiled tar |
2a5ccb22 LC |
85 | anyway, you must find the incorrectly renamed file and move it back |
86 | to lib/locale.pm. | |
d420ca49 | 87 | |
a83b6f46 | 88 | =head2 Compiler and Related Tools on Solaris. |
d420ca49 AD |
89 | |
90 | You must use an ANSI C compiler to build perl. Perl can be compiled | |
91 | with either Sun's add-on C compiler or with gcc. The C compiler that | |
92 | shipped with SunOS4 will not do. | |
93 | ||
94 | =head3 Include /usr/ccs/bin/ in your PATH. | |
95 | ||
96 | Several tools needed to build perl are located in /usr/ccs/bin/: ar, | |
97 | as, ld, and make. Make sure that /usr/ccs/bin/ is in your PATH. | |
98 | ||
99 | You need to make sure the following packages are installed | |
100 | (this info is extracted from the Solaris FAQ): | |
101 | ||
102 | for tools (sccs, lex, yacc, make, nm, truss, ld, as): SUNWbtool, | |
103 | SUNWsprot, SUNWtoo | |
104 | ||
105 | for libraries & headers: SUNWhea, SUNWarc, SUNWlibm, SUNWlibms, SUNWdfbh, | |
106 | SUNWcg6h, SUNWxwinc, SUNWolinc | |
107 | ||
108 | for 64 bit development: SUNWarcx, SUNWbtoox, SUNWdplx, SUNWscpux, | |
109 | SUNWsprox, SUNWtoox, SUNWlmsx, SUNWlmx, SUNWlibCx | |
110 | ||
2a5ccb22 LC |
111 | If you are in doubt which package contains a file you are missing, |
112 | try to find an installation that has that file. Then do a | |
113 | ||
114 | grep /my/missing/file /var/sadm/install/contents | |
115 | ||
116 | This will display a line like this: | |
117 | ||
118 | /usr/include/sys/errno.h f none 0644 root bin 7471 37605 956241356 SUNWhea | |
119 | ||
b29a8fb9 | 120 | The last item listed (SUNWhea in this example) is the package you need. |
2a5ccb22 | 121 | |
d420ca49 AD |
122 | =head3 Avoid /usr/ucb/cc. |
123 | ||
124 | You don't need to have /usr/ucb/ in your PATH to build perl. If you | |
2a5ccb22 LC |
125 | want /usr/ucb/ in your PATH anyway, make sure that /usr/ucb/ is NOT |
126 | in your PATH before the directory containing the right C compiler. | |
d420ca49 AD |
127 | |
128 | =head3 Sun's C Compiler | |
129 | ||
130 | If you use Sun's C compiler, make sure the correct directory | |
2a5ccb22 | 131 | (usually /opt/SUNWspro/bin/) is in your PATH (before /usr/ucb/). |
d420ca49 AD |
132 | |
133 | =head3 GCC | |
134 | ||
9a04b58a RS |
135 | If you use gcc, make sure your installation is recent and complete. |
136 | Perl versions since 5.6.0 build fine with gcc > 2.8.1 on Solaris >= | |
137 | 2.6. | |
138 | ||
139 | You must Configure perl with | |
d420ca49 AD |
140 | |
141 | sh Configure -Dcc=gcc | |
142 | ||
9a04b58a RS |
143 | If you don't, you may experience strange build errors. |
144 | ||
d420ca49 | 145 | If you have updated your Solaris version, you may also have to update |
9a04b58a | 146 | your gcc. For example, if you are running Solaris 2.6 and your gcc is |
d420ca49 | 147 | installed under /usr/local, check in /usr/local/lib/gcc-lib and make |
2a5ccb22 LC |
148 | sure you have the appropriate directory, sparc-sun-solaris2.6/ or |
149 | i386-pc-solaris2.6/. If gcc's directory is for a different version of | |
150 | Solaris than you are running, then you will need to rebuild gcc for | |
151 | your new version of Solaris. | |
d420ca49 AD |
152 | |
153 | You can get a precompiled version of gcc from | |
2a5ccb22 LC |
154 | L<http://www.sunfreeware.com/>. Make sure you pick up the package for |
155 | your Solaris release. | |
d420ca49 AD |
156 | |
157 | =head3 GNU as and GNU ld | |
158 | ||
74144837 AD |
159 | The following information applies to gcc version 2. Volunteers to |
160 | update it as appropropriate for gcc version 3 would be appreciated. | |
161 | ||
d420ca49 | 162 | The versions of as and ld supplied with Solaris work fine for building |
74144837 AD |
163 | perl. There is normally no need to install the GNU versions to |
164 | compile perl. | |
d420ca49 AD |
165 | |
166 | If you decide to ignore this advice and use the GNU versions anyway, | |
167 | then be sure that they are relatively recent. Versions newer than 2.7 | |
168 | are apparently new enough. Older versions may have trouble with | |
169 | dynamic loading. | |
170 | ||
74144837 AD |
171 | If you wish to use GNU ld, then you need to pass it the -Wl,-E flag. |
172 | The hints/solaris_2.sh file tries to do this automatically by executing | |
173 | the following commands: | |
174 | ||
175 | ccdlflags="$ccdlflags -Wl,-E" | |
176 | lddlflags="$lddlflags -Wl,-E -G" | |
177 | ||
178 | However, over the years, changes in gcc, GNU ld, and Solaris ld have made | |
179 | it difficult to automatically detect which ld ultimately gets called. | |
180 | You may have to manually edit config.sh and add the -Wl,-E flags | |
181 | yourself, or else run Configure interactively and add the flags at the | |
182 | appropriate prompts. | |
183 | ||
d420ca49 AD |
184 | If your gcc is configured to use GNU as and ld but you want to use the |
185 | Solaris ones instead to build perl, then you'll need to add | |
186 | -B/usr/ccs/bin/ to the gcc command line. One convenient way to do | |
187 | that is with | |
188 | ||
189 | sh Configure -Dcc='gcc -B/usr/ccs/bin/' | |
190 | ||
191 | Note that the trailing slash is required. This will result in some | |
2a5ccb22 | 192 | harmless warnings as Configure is run: |
d420ca49 AD |
193 | |
194 | gcc: file path prefix `/usr/ccs/bin/' never used | |
195 | ||
196 | These messages may safely be ignored. | |
197 | (Note that for a SunOS4 system, you must use -B/bin/ instead.) | |
198 | ||
199 | Alternatively, you can use the GCC_EXEC_PREFIX environment variable to | |
200 | ensure that Sun's as and ld are used. Consult your gcc documentation | |
201 | for further information on the -B option and the GCC_EXEC_PREFIX variable. | |
202 | ||
203 | =head3 GNU make | |
204 | ||
205 | Sun's make works fine for building perl. | |
206 | If you wish to use GNU make anyway, be sure that the set-group-id bit is not | |
207 | set. If it is, then arrange your PATH so that /usr/ccs/bin/make is | |
208 | before GNU make or else have the system administrator disable the | |
209 | set-group-id bit on GNU make. | |
210 | ||
211 | =head3 Avoid libucb. | |
212 | ||
213 | Solaris provides some BSD-compatibility functions in /usr/ucblib/libucb.a. | |
214 | Perl will not build and run correctly if linked against -lucb since it | |
215 | contains routines that are incompatible with the standard Solaris libc. | |
216 | Normally this is not a problem since the solaris hints file prevents | |
217 | Configure from even looking in /usr/ucblib for libraries, and also | |
218 | explicitly omits -lucb. | |
219 | ||
a83b6f46 | 220 | =head2 Environment for Compiling Perl on Solaris |
d420ca49 AD |
221 | |
222 | =head3 PATH | |
223 | ||
224 | Make sure your PATH includes the compiler (/opt/SUNWspro/bin/ if you're | |
225 | using Sun's compiler) as well as /usr/ccs/bin/ to pick up the other | |
226 | development tools (such as make, ar, as, and ld). Make sure your path | |
227 | either doesn't include /usr/ucb or that it includes it after the | |
228 | compiler and compiler tools and other standard Solaris directories. | |
229 | You definitely don't want /usr/ucb/cc. | |
230 | ||
231 | =head3 LD_LIBRARY_PATH | |
232 | ||
233 | If you have the LD_LIBRARY_PATH environment variable set, be sure that | |
234 | it does NOT include /lib or /usr/lib. If you will be building | |
235 | extensions that call third-party shared libraries (e.g. Berkeley DB) | |
236 | then make sure that your LD_LIBRARY_PATH environment variable includes | |
237 | the directory with that library (e.g. /usr/local/lib). | |
238 | ||
239 | If you get an error message | |
240 | ||
241 | dlopen: stub interception failed | |
242 | ||
243 | it is probably because your LD_LIBRARY_PATH environment variable | |
244 | includes a directory which is a symlink to /usr/lib (such as /lib). | |
245 | The reason this causes a problem is quite subtle. The file | |
246 | libdl.so.1.0 actually *only* contains functions which generate 'stub | |
247 | interception failed' errors! The runtime linker intercepts links to | |
248 | "/usr/lib/libdl.so.1.0" and links in internal implementations of those | |
249 | functions instead. [Thanks to Tim Bunce for this explanation.] | |
250 | ||
251 | =head1 RUN CONFIGURE. | |
252 | ||
253 | See the INSTALL file for general information regarding Configure. | |
254 | Only Solaris-specific issues are discussed here. Usually, the | |
255 | defaults should be fine. | |
256 | ||
a83b6f46 | 257 | =head2 64-bit Issues with Perl on Solaris. |
d420ca49 AD |
258 | |
259 | See the INSTALL file for general information regarding 64-bit compiles. | |
260 | In general, the defaults should be fine for most people. | |
261 | ||
262 | By default, perl-5.6.0 (or later) is compiled as a 32-bit application | |
263 | with largefile and long-long support. | |
264 | ||
265 | =head3 General 32-bit vs. 64-bit issues. | |
266 | ||
2a5ccb22 LC |
267 | Solaris 7 and above will run in either 32 bit or 64 bit mode on SPARC |
268 | CPUs, via a reboot. You can build 64 bit apps whilst running 32 bit | |
269 | mode and vice-versa. 32 bit apps will run under Solaris running in | |
270 | either 32 or 64 bit mode. 64 bit apps require Solaris to be running | |
b29a8fb9 | 271 | 64 bit mode. |
d420ca49 AD |
272 | |
273 | Existing 32 bit apps are properly known as LP32, i.e. Longs and | |
274 | Pointers are 32 bit. 64-bit apps are more properly known as LP64. | |
275 | The discriminating feature of a LP64 bit app is its ability to utilise a | |
276 | 64-bit address space. It is perfectly possible to have a LP32 bit app | |
2a5ccb22 | 277 | that supports both 64-bit integers (long long) and largefiles (> 2GB), |
d420ca49 AD |
278 | and this is the default for perl-5.6.0. |
279 | ||
280 | For a more complete explanation of 64-bit issues, see the Solaris 64-bit | |
5511f325 | 281 | Developer's Guide at L<http://docs.sun.com:80/ab2/coll.45.13/SOL64TRANS/> |
d420ca49 AD |
282 | |
283 | You can detect the OS mode using "isainfo -v", e.g. | |
284 | ||
285 | fubar$ isainfo -v # Ultra 30 in 64 bit mode | |
286 | 64-bit sparcv9 applications | |
287 | 32-bit sparc applications | |
288 | ||
289 | By default, perl will be compiled as a 32-bit application. Unless you | |
2a5ccb22 | 290 | want to allocate more than ~ 4GB of memory inside Perl, you probably |
d420ca49 AD |
291 | don't need Perl to be a 64-bit app. |
292 | ||
5511f325 | 293 | =head3 Large File Support |
d420ca49 AD |
294 | |
295 | For Solaris 2.6 and onwards, there are two different ways for 32-bit | |
2a5ccb22 | 296 | applications to manipulate large files (files whose size is > 2GByte). |
d420ca49 AD |
297 | (A 64-bit application automatically has largefile support built in |
298 | by default.) | |
299 | ||
300 | First is the "transitional compilation environment", described in | |
301 | lfcompile64(5). According to the man page, | |
302 | ||
303 | The transitional compilation environment exports all the | |
304 | explicit 64-bit functions (xxx64()) and types in addition to | |
305 | all the regular functions (xxx()) and types. Both xxx() and | |
306 | xxx64() functions are available to the program source. A | |
307 | 32-bit application must use the xxx64() functions in order | |
308 | to access large files. See the lf64(5) manual page for a | |
309 | complete listing of the 64-bit transitional interfaces. | |
310 | ||
311 | The transitional compilation environment is obtained with the | |
312 | following compiler and linker flags: | |
313 | ||
314 | getconf LFS64_CFLAGS -D_LARGEFILE64_SOURCE | |
315 | getconf LFS64_LDFLAG # nothing special needed | |
316 | getconf LFS64_LIBS # nothing special needed | |
317 | ||
318 | Second is the "large file compilation environment", described in | |
319 | lfcompile(5). According to the man page, | |
320 | ||
321 | Each interface named xxx() that needs to access 64-bit entities | |
322 | to access large files maps to a xxx64() call in the | |
323 | resulting binary. All relevant data types are defined to be | |
324 | of correct size (for example, off_t has a typedef definition | |
325 | for a 64-bit entity). | |
326 | ||
327 | An application compiled in this environment is able to use | |
328 | the xxx() source interfaces to access both large and small | |
329 | files, rather than having to explicitly utilize the transitional | |
330 | xxx64() interface calls to access large files. | |
331 | ||
332 | Two exceptions are fseek() and ftell(). 32-bit applications should | |
333 | use fseeko(3C) and ftello(3C). These will get automatically mapped | |
334 | to fseeko64() and ftello64(). | |
335 | ||
336 | The large file compilation environment is obtained with | |
337 | ||
338 | getconf LFS_CFLAGS -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 | |
339 | getconf LFS_LDFLAGS # nothing special needed | |
340 | getconf LFS_LIBS # nothing special needed | |
341 | ||
342 | By default, perl uses the large file compilation environment and | |
343 | relies on Solaris to do the underlying mapping of interfaces. | |
344 | ||
345 | =head3 Building an LP64 Perl | |
346 | ||
b29a8fb9 JH |
347 | To compile a 64-bit application on an UltraSparc with a recent Sun Compiler, |
348 | you need to use the flag "-xarch=v9". getconf(1) will tell you this, e.g. | |
d420ca49 AD |
349 | |
350 | fubar$ getconf -a | grep v9 | |
351 | XBS5_LP64_OFF64_CFLAGS: -xarch=v9 | |
352 | XBS5_LP64_OFF64_LDFLAGS: -xarch=v9 | |
353 | XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9 | |
354 | XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9 | |
355 | XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9 | |
356 | XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9 | |
357 | _XBS5_LP64_OFF64_CFLAGS: -xarch=v9 | |
358 | _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9 | |
359 | _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9 | |
360 | _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9 | |
361 | _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9 | |
362 | _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9 | |
363 | ||
b29a8fb9 JH |
364 | This flag is supported in Sun WorkShop Compilers 5.0 and onwards |
365 | (now marketed under the name Forte) when used on Solaris 7 or later on | |
366 | UltraSparc systems. | |
2a5ccb22 LC |
367 | |
368 | If you are using gcc, you would need to use -mcpu=v9 -m64 instead. This | |
369 | option is not yet supported as of gcc 2.95.2; from install/SPECIFIC | |
370 | in that release: | |
d420ca49 | 371 | |
2a5ccb22 LC |
372 | GCC version 2.95 is not able to compile code correctly for sparc64 |
373 | targets. Users of the Linux kernel, at least, can use the sparc32 | |
374 | program to start up a new shell invocation with an environment that | |
375 | causes configure to recognize (via uname -a) the system as sparc-*-* | |
376 | instead. | |
d420ca49 AD |
377 | |
378 | All this should be handled automatically by the hints file, if | |
379 | requested. | |

381 | =head3 Long Doubles. |
382 | ||
383 | As of 5.6.0, long doubles are not working. | |
384 | ||
a83b6f46 | 385 | =head2 Threads in Perl on Solaris. |
d420ca49 AD |
386 | |
387 | It is possible to build a threaded version of perl on Solaris. The entire | |
388 | perl thread implementation is still experimental, however, so beware. | |
389 | Perl uses the sched_yield(3RT) function. In versions of Solaris up | |
390 | to 2.6, that function is in -lposix4. Starting with Solaris 7, it is | |
391 | in -lrt. The hints file should handle adding this automatically. | |
392 | ||
a83b6f46 | 393 | =head2 Malloc Issues with Perl on Solaris. |
d420ca49 | 394 | |
83bd2f30 LC |
395 | Starting from Perl 5.7.1 Perl uses the Solaris malloc, since the perl |
396 | malloc breaks when dealing with more than 2GB of memory, and the Solaris | |
397 | malloc also seems to be faster. | |
398 | ||
399 | If you for some reason (such as binary backward compatibility) really | |
400 | need to use perl's malloc, you can rebuild Perl from the sources | |
401 | and Configure the build with | |
402 | ||
403 | sh Configure -Dusemymalloc | |

405 | You should not use perl's malloc if you are building with gcc. There |
406 | are reports of core dumps, especially in the PDL module. The problem | |
407 | appears to go away under -DDEBUGGING, so it has been difficult to | |
5511f325 | 408 | track down. Sun's compiler appears to be okay with or without perl's |

415 | =item Dynamic Loading Problems With GNU as and GNU ld | |
416 | ||
417 | If you have problems with dynamic loading using gcc on SunOS or | |
418 | Solaris, and you are using GNU as and GNU ld, see the section | |
419 | L<"GNU as and GNU ld"> above. | |
420 | ||
421 | =item ld.so.1: ./perl: fatal: relocation error: | |
422 | ||
423 | If you get this message on SunOS or Solaris, and you're using gcc, | |
424 | it's probably the GNU as or GNU ld problem in the previous item | |
425 | L<"GNU as and GNU ld">. | |
426 | ||
427 | =item dlopen: stub interception failed | |
428 | ||
429 | The primary cause of the 'dlopen: stub interception failed' message is | |
430 | that the LD_LIBRARY_PATH environment variable includes a directory | |
431 | which is a symlink to /usr/lib (such as /lib). See | |
432 | L<"LD_LIBRARY_PATH"> above. | |
433 | ||
434 | =item #error "No DATAMODEL_NATIVE specified" | |
435 | ||
436 | This is a common error when trying to build perl on Solaris 2.6 with a | |
437 | gcc installation from Solaris 2.5 or 2.5.1. The Solaris header files | |
438 | changed, so you need to update your gcc installation. You can either | |
439 | rerun the fixincludes script from gcc or take the opportunity to | |
440 | update your gcc installation. | |
441 | ||
442 | =item sh: ar: not found | |
443 | ||
444 | This is a message from your shell telling you that the command 'ar' | |
445 | was not found. You need to check your PATH environment variable to | |
446 | make sure that it includes the directory with the 'ar' command. This | |
447 | is a common problem on Solaris, where 'ar' is in the /usr/ccs/bin/ | |
448 | directory. | |

455 | |
456 | op/stat.t test 4 may fail if you are on a tmpfs of some sort. | |
457 | Building in /tmp sometimes shows this behavior. The | |
458 | test suite detects if you are building in /tmp, but it may not be able | |
459 | to catch all tmpfs situations. | |

a83b6f46 | 475 | =head2 Limits on Numbers of Open Files on Solaris. |
d420ca49 AD |
476 | |
477 | The stdio(3C) manpage notes that only 255 files may be opened using | |
478 | fopen(), and only file descriptors 0 through 255 can be used in a | |
479 | stream. Since perl calls open() and then fdopen(3C) with the | |
480 | resulting file descriptor, perl is limited to 255 simultaneous open | |
481 | files. | |

489 | ||
a83b6f46 | 490 | =head2 Proc::ProcessTable on Solaris |
d420ca49 AD |
491 | |
492 | Proc::ProcessTable does not compile on Solaris with perl5.6.0 and higher | |
493 | if you have LARGEFILES defined. Since largefile support is the | |
494 | default in 5.6.0 and later, you have to take special steps to use this | |
495 | module. | |
496 | ||
497 | The problem is that various structures visible via procfs use off_t, | |
498 | and if you compile with largefile support these change from 32 bits to | |
499 | 64 bits. Thus what you get back from procfs doesn't match up with | |
500 | the structures in perl, resulting in garbage. See proc(4) for further | |
501 | discussion. | |
502 | ||
503 | A fix for Proc::ProcessTable is to edit Makefile to | |
504 | explicitly remove the largefile flags from the ones MakeMaker picks up | |
505 | from Config.pm. This will result in Proc::ProcessTable being built | |
2a5ccb22 | 506 | under the correct environment. Everything should then be OK as long as |
d420ca49 AD |
507 | Proc::ProcessTable doesn't try to share off_t's with the rest of perl, |
508 | or if it does they should be explicitly specified as off64_t. | |
509 | ||
5511f325 | 510 | =head2 BSD::Resource on Solaris |
d420ca49 AD |
511 | |
512 | BSD::Resource versions earlier than 1.09 do not compile on Solaris | |
513 | with perl 5.6.0 and higher, for the same reasons as Proc::ProcessTable. | |
514 | BSD::Resource versions starting from 1.09 have a workaround for the problem. | |
515 | ||
5511f325 | 516 | =head2 Net::SSLeay on Solaris |
2a5ccb22 LC |
517 | |
518 | Net::SSLeay requires a /dev/urandom to be present. This device is not | |
519 | part of Solaris. You can either get the package SUNWski (packaged with | |
520 | several Sun software products, for example the Sun WebServer, which is | |
521 | part of the Solaris Server Intranet Extension, or the Sun Directory | |
522 | Services, part of Solaris for ISPs) or download the ANDIrand package | |
523 | from L<http://www.cosy.sbg.ac.at/~andi/>. If you use SUNWski, make a | |
524 | symbolic link /dev/urandom pointing to /dev/random. | |
525 | ||
526 | It may be possible to use the Entropy Gathering Daemon (written in | |
527 | Perl!), available from L<http://www.lothar.com/tech/crypto/>. | |
