Re: Problems with Apache-AuthCookie mod_perl 1.99
Michael, I've got most of the changes done. No major changes were required but I'm still stuck on mod_perl 2's new method handlers. To get past this hurdle I've moved away from method handlers and put everything into a single package. As soon as somebody gives me a hand with method handlers ala 2.0 I'll forward the code to you. -pete Michael J Schout wrote: > On Thu, 2 May 2002, Per Einar Ellefsen wrote: > > > At 21:25 02.05.2002, Peter Rothermel wrote: > > >greetings, > > > > > >Has anybody had any luck getting Apache-AuthCookie going > > >on an Apache 2.0 / mod_perl 1.99 setup?

[RFC] New Subject Tag for mod_perl 2.x postings
Hi! As there are more and more mod_perl 2.x related questions on the mailing list, it would be a good idea to introduce a new subject tag (as in http://perl.apache.org/email-etiquette.html#Tags ): Something like: [mod_perl 2.x] [mp2] [2x] [2.x] ?? What do you think? It would definitly keep my mailbox tidier...

Phew, and I just thought that I did not like the design. It might have good performance now, but the idea sounds valid that in an error handler performance does not matter.

How do I determine end of request? (mod_perl 2.0)
Hello, I'm fairly new to using mod_perl. I've been able to find lots of resources dealing with mod_perl 1.x, but the documentation for 2.0 is rather sparse. I'm pretty sure what I need to do can only be handled by Apache 2.0 & thus I'm forced to use mod_perl 2.0... (well 1.99) I'm trying to proxy ServerB through ServerA... ok that's simple enough with mod_proxy. However, links, embedded images, etc in the proxied document end up broken if they are non-relative links (ie. start with a slash). Example: on ServerB is a document say: /sales/products.html in products.html it links to /images/logo.gif accessing /sales/products.html using ServerB everything is fine. But, if I want to proxy ServerB via ServerA... say ProxyPass /EXTERNAL http://ServerB If I goto http://ServerA/EXTERNAL/sales/products.html the embedded image /images/logo.gif is requested from ServerA. So to handle this I wanted to write a filer for ServerA to parse all pages served via Location /EXTERNAL and "fix" the links. I wrote a handler (see below) using HTML::Parser to extract the tags that would contain links and process them. It works great for the most part... however, it seems like instead of ServerA getting the entire output from ServerB, it gets it in chunks which get processed individually. This causes my handler to fail when a tag is split between 2 chunks. What I think needs to be done is to build up the document in a variable $html .= $buffer; and then call the $p->$parse($html) once the entire document has been received by ServerA (or maybe as simple of only calling $p->eof; at that point). Or is there a better way to do this? One problem I've found so far is I need to fix style sheets, but I can probably write a special handler for them once I get this problem fixed. Thanks! ## package RewriteLinks; use strict; use Apache::Filter; use Apache::RequestUtil; use APR::Table; use HTML::Parser; my %ReplaceAttrs = ( a => 'href', img => 'src', link => 'href', td=> 'background', form => 'action' ); my $filter; sub handler { $filter = shift; ### Create parser object ### my $p = HTML::Parser->new( api_version => 3 ); $p->handler(start => \&do_tags, 'tagname, attr, text' ); $p->handler(default => \&default, 'text'); while ($filter->read(my $buffer, 32678)) { $p->parse($buffer); } $p->eof; # signal end of document 1; } sub do_tags { my ($tagname, $attr, $text) = @_; ## only need to modify tags with url-like attributes starting with a slash if ($$attr{$ReplaceAttrs{$tagname}} =~ m|^/|) { my $TAG = "<" . uc($tagname); foreach my $key (keys %$attr) { $TAG .= ' ' . uc($key) .

Yes, except for the random part. There is no randomness involved here. You should use a secret key stored on your server.

Depending on my paranoia I could either get fresh random bits each >time (and have a good hardware source for this then) or keep it around for >a bit and throw it away after a period. I think I understand you correctly, but I'm not sure. You mention the sequence being incremented for uniqueness and the digest. I think you propose to send the sequence along with the digest (the digest containing that bit of randomness along with the sequence), but you also mention keeping the random bits around for only a short time, which would indicate they aren't being used to verify the sequence, but produce the sequence via the hash. A digest is not unique, especially with the random bit of data thrown in. For example, MD5 has 128 bits, but can hash any length string. There are more than 2^128 strings that MD5 can take to 128 bits. Therefore, MD5 does not produce a unique value, though it is a reproducable value (the same input string will always produce the same output string). You can replace MD5 with MHX (my hash X) and the number of bits with some other length and the results are still the same -- in other words, no hash will give unique results. The secret string concatenated with the unique number and then hashed can be used to guarantee that the number has not been tampered with, but the secret string would need to be constant to be able to catch tampering. Otherwise, how can you tell if the hash is correct? -- James Smith <[EMAIL PROTECTED]>, 979-862-3725 Texas A&M CIS Operating Systems Group, Unix
Re: Cheap and unique
I've been following this conversation and I'd like to clarify whether my idea (since I and others want to do this as well) would be use an incrementing counter for uniqueness. Then also store a bit of secret randomness, concatenate both values together and create a digest hash. That hash would be sent along with the sequence as well. This would allow uniqueness and prevent guessing since the digest would have to match as well. Depending on my paranoia I could either get fresh random bits each time (and have a good hardware source for this then) or keep it around for a bit and throw it away after a period. Does that sound right?

mod_perl install from tarball
i am trying to install mod_perl and apache from tarball. after untarring, i created the makepl_args.mod_perl file in my home dir with my options. by the way, i am building this on a rh7.1 machine with mod_perl already installed. i am building this to learn. anyhow, when i run perl Makefile.PL, i get this... [boex@rootabega mod_perl-1.99_01]$ perl Makefile.PL You are running Perl version 5.006 We strongly suggest to upgrade to at least 5.6.1 mod_perl/1.24_01 installation detected...not ok cannot install mod_perl/1.99_01 on top of mod_perl/1.24_01 use MP_INST_APACHE2=1 option or to force installation delete: /usr/lib/perl5/site_perl/5.6.0/i386-linux/mod_perl.pm first, i am running perl 5.6.0. as the same user, i run perl -v and get.. [boex@rootabega boex]$ perl -v This is perl, v5.6.0 built for i386-linux Copyright 1987-2000, Larry Wall second, is the version i downloaded, 1.99_01 only for apache 2.0? are these versions being split like apache 1.3 and 2.0, with and without threads? if so, should i download a different version? if not, what route should i go to install? my goal is to install from scratch so i can learn more and to install with the same directory structure, /usr/local/apache-mod_perl/ on my production and dev machines. i want to be able to run a mod_perl or non-mod_perl enabled web server. matt Matthew Boex Sendmail Group 312.822.3955

Here is the relevant part of my config file # AuthCookieDBI config PerlModule Apache::AuthCookieDBI PerlSetVar RMSPath / PerlSetVar RMSLoginScript /rms/login PerlSetVar RMSDBI_SecretKeyFile /usr/local/apache/RMSsecretkeyfile PerlSetVar etc..

The Eagle book says (page 58): Apache processes the configuration directives on a first-come, first-serve basis, so in certain cases, the order in which directives appear is important. So Apache passes PerlModule and PerlSetVar to mod_perl as it finds it in its configuration file. If mod_perl loaded modules as they come by means of PerlModule that would explain why variables set with PerlSetVar after that directive are not seen by the very module at loading time. As that seems to be the behaviour in my static mod_perl and Jacob Davies said he had to change the documentation (and he knows more mod_perl than I for sure), I don't understand why the order does not matter in your machine. Do we have the same version of the module (v1.18)? -- fxn
