They can not reach your client directory (without the help from a program on your client). Your options: * set a content type in the generated file that tells the browser that the file should be stored and not shown, e.g.: <dtml-call "RESPONSE.setHeader('Content-Type','application')"> The browser will in this case pop up a file dialog where you can specify where to put the file. * Use a Python script (e.g. ZPublisher.Client) on your client to fetch the file and store it * Write some Java applet that fetch the file and stores it. You will need to give it high permissions (you probably will need to sign it), such that it is able to write to your local file system. For obvious security reasons, normal Java applets are not allowed to write to your file system. Dieter

Sorry... Further to my last email, man cron man 1 crontab man 5 crontab should tell you all you need to know about cron. http://www.python.org/doc/current/lib/module-httplib.html tells you about writing simple HTTP clients in Python.

This sounds like a job for cron: man cron man crontab If the job needs to get infomation which is held in Zope, you'd need to write a small HTTP client in Python which gets the info it needs by querying the Zope server just as if it was a web browser being driven by a human, formats it, and sends the email. Another approach would be to look into xmlrpc. But understand: the client works _outside_ of Zope. This is necessary to run it as a cron job, which is the best way to run a timed process under Unix/Linux. Good luck! -Andy PS: Please don't send HTML email to the list! :-) -- Andy Gimblett <andy.gimblett(a)ftech.net> Programmer Frontier Internet Services Limited <www.frontier-internet.ltd.uk> Tel: 029 20 820 044 Fax: 029 20 820 035 Statements made are at all times subject to Frontier's Terms and Conditions of Business, which are available upon request.

hi, I am using ZOPE in LINUX RedHat 6.2 My application need to send mails everyday to the people. For that I have written one Dtml method. which will refresh every 24hr.(using html tags.) But for that, that page should be running in the browser always. That I don't want. Is there any other solution for that. subrahmanyan.

Can't use <dtml-in> with <dtml-boundary>
by Kelvin Cheong 22 Mar '01

22 Mar '01

Hi all, Is there anyway to use <dtml-in> tags with <dtml-boundary>??? I'm trying to allow users to attach multiple files but i can't retrieve the "list" of files (of course lists indicates an undefined number of files), as it seems Zope won't allow <dtml-boundary> and <dtml-in> to get along. My codes are : <dtml-sendmail mailhost="MailHost"> From: webmaster(a)vcn.com.my To: amoebia(a)vcn.com.my Subject: attach <dtml-mime type=text/plain encode=7bit> <dtml-boundary type=image/jpeg disposition=attachment encode=base64><dtml-in filelist><dtml-var "attachLFS[_['sequence-item']].data"></dtml-in> </dtml-mime>  </dtml-sendmail> So say I have files foo1.jpg foo2.txt foo3.gif I'm trying to generate something lke : <dtml-sendmail mailhost="MailHost"> From: webmaster(a)vcn.com.my To: amoebia(a)vcn.com.my Subject: attach <dtml-mime type=text/plain encode=7bit> <dtml-var getname> <dtml-boundary type=image/jpeg disposition=attachment encode=base64><dtml-var foo1.jpg> <dtml-boundary type=image/jpeg disposition=attachment encode=base64><dtml-var foo2.txt> <dtml-boundary type=image/jpeg disposition=attachment encode=base64><dtml-var foo3.gif> </dtml-mime> </dtml-sendmail> Anyone done this before? Or perhaps can anyone suggest a workaround? Thanx in advance dudes and dudettes!! amoebia.

One could had this code do z2.py just before the ayncore.loop(): sockettimeout=60 import timeoutsocket timeoutsocket.setDefaultSocketTimeout(sockettimeout) and then any python code you create (external methods, etc) that opens tcp sockets will "see" this timeoutsocket default set in z2.py. Note: I tested (on linux 2.3.1.b1) and it works but use it at your own risk.

I get a problem with timeoutsocket using zope on NT, on Linux it works ok,i.e, it gives me socket timeout when it runs for time > mydefaulttimeout. It's in timeoutsocket.py, line 244, in connect. On NT I tryed in a lower version of zope, so I think could be related with the _socket of my NT zope's python, I'll try later.

Hi, has anyone put timeoutsocket.py (http://www.timo-tasi.org/python/timeoutsocket.py) to work with zope? For instance, doing an external method that fetchs a site with httplib but add in the code a import of timeoutsocket and setting the default timeout, something like this: import timeoutsocket import httplib imeoutsocket.setDefaultSocketTimeout(20) H = httplib.HTTP("www.python.org") ...

[ ANN ] LDAPLoginAdapter 1.1 released
by Jens Vagelpohl 21 Mar '01

21 Mar '01

LDAPLoginAdapter 1.1, a user folder replacement that authenticates against an LDAP server, has been released. You can view some of the documentation and download the software at http://www.dataflake.org/software/ldaploginadapter/ A Tracker at that same address allows you to easily file bug reports or feature requests for this product. Improvements and bugfixes since the last announcement include: **LDAPLoginAdapter 1.1** Features Added: * Instead of hardcoding fixed publicly available attributes onto the LDAPUser object you can now take full control of the mapping from LDAP attribute to public user object attribute. A public user object attribute is an attribute that is directly accessible on the user object. DTML code like "AUTHENTICATED_USER.email" is an example of accessing a directly accessible attribute on the user object. A lot of legacy DTML code relies on such attributes. Bugs fixed: * finduser() now lowercases all DN records from valid groups and compares it to a lowercased DN from any search results among user records. This fixes records not showing up if the capitalization in the group and on the user record is different. * When a user object was created the code expected a "mail" attribute on the LDAP record to set the email attribute used for compatibility with the Tracker. This has been repaired and will just default to an empty string. * Users who use tools like PADL's migration script end up with records that do not have the expected "sn" attribute. This is not set to a default value in finduser() to avoid errors in case it is not there. This will make the LDAPLoginAdapter compatible with user records of type posixAccount. **LDAPLoginAdapter 1.0** Bugs fixed: * Due to a bug in checking the return values from an LDAP search the cache can be polluted by invalid records for failed logins. This did not constitue a security breach, just more processing than necessary. **LDAPLoginAdapter 1.0beta3** Bugs Fixed: * Moved the LDAP search scope translation list from a volatile attribute on the LDAPLoginAdapter to a module-level attribute. This avoids any re-initialization calls. * Eliminated the extra attribute _v_loglines that counted the length of the log. A simple call to len(self._v_log) replaces it where log length info is needed. * Created one centralized method that handles connecting to and searching the LDAP server. This allows centralized error handling and makes for less and cleaner code. So far finduser, getUserDetails, getGroups, getUserNames and _lookupuser have been converted to use it instead of having their own connection code. * Rooted out error that would put a known user into the cache even though the password was not matched. This was not a security error since the broken user had the wrong password and failed any tests in validate() * Rigorous pruning of overly long lines of code to pare everything down to 80 chars width max * Avoiding unnecessary calls to the logging routine by checking for the correct log level *before* the call and not in the logging method. * Added a file, SAMPLE_RECORDS.txt, that shows a sample group- and user record. This will hopefully make it easier to understand the types of LDAP records needed. Features added: * Nicer Search screen adopted from the LDAPUserManager
