Two new MacBooks: Personal Web Sharing ODDITY

Dear MacBook, Airport or Apple networking pro's please enlighten us:
We are longtime Mac users and just bought two new MacBooks (one white, one black for what that matters) turned on "Personal Web Sharing", join one to the other's network/comp name there in the Aiport drop-down menu and partial success: web browser accesses internet fine but neither email client (Apple's Mail) or ANY over our many IM services (MSN, AIM, ICQ, etc) works.
Could it be that i am not allowed to have the Firewalls on?
Or??
Help.
Thanks!!
D&D

UPDATE:
.... ok, so I turned OFF firewalling on BOTH laptops and now ALL internet related services/apps function.
But that is NO real solution if now we have no protection. We are on a very busy network and our concern is that a bunch of the other 15,000 young board Ukrainian hacker kids would love to sneak on in and start exploring our cool Mac's.
If "Windows Sharing" is NOT checked in Services does that make it impossible then for any incoming searches or connection attempts to connect?
We do have "Personal File Sharing" checked in Services because we use/need that ability to share files between our comps.
What to do?
Please help us get this fixed so that both full internet services are available to both comps but NO PC on the network here could come explore our HDrives.
THANKS!

  • Pixelpost and Personal Web Sharing in Tiger

    Dear Friends:
    I figured out how to install Pixelpost (for a photoblog) in my OS X Tiger system -- by using MAMP. I changed the Document Root in MAMP so that now it looks to the Personal Web Sharing folder in the Mac (the Sites folder in the /usr/ space). The installation of Pixelpost works fine, letting me add images, manage it, etc. However, when I type in the computer address ("personal website") as provided in the Sharing tab under system preferences, it does not bring me at all to the photoblog. For instance:
    http://my.computer.address/ (just brings me to the regular Apache Server notice that it is running)
    if I type this:
    http://my.computer.address/~username/
    It brings me to the generic OS X page in place. But when I type:
    http://my.computer.address/~username/pixelpost/
    it opens to the pixelpost directory which I placed in the Sites folder. What I'd like to do is figure out what address will call up this blog so that others can access it.
    The blog comes up fine under this URL:
    http://localhost:8888/pixelpost/
    But that's not a proper address for external viewing. So, what address should I provide others? I've tried various configurations with the address provided in the Sharing tab of System Preferences, but no luck so far.
    Thanks!

    I changed the Document Root in MAMP so that now it looks to the Personal Web Sharing folder in the Mac (the Sites folder in the /usr/ space
    I think you mean /Users/ space. /usr is something completely different.
    http://my.computer.address/ (just brings me to the regular Apache Server notice that it is running)
    Then it means you didn't change the DocumentRoot like you think you did. If you did, and assuming you restarted Apache after changing the DocumentRoot, then this URL would point to whatever directory you specified (/Users/whoever/Sites) and not /Library/WebServer/Documents.
    But [http://localhost:8888/pixelpost> is not a proper address for external viewing.
    but it can be. If all you're using this for is PixelPost then just setup the port forwarding on your router to forward to port 8888 rather than port 80 and you're done.
    Now, that said, the fact that you're using two different ports here (port 80 and port 8888) means that, at the very least, you are running two virtual hosts, or quite possibly two completely separate Apache instances.
    That could explain why changing the DocumentRoot doesn't help. You may have changed either the PixelPost VirtualHost configuration, or the MAMP-specific server configuration, but that's not the server/virtualhost you're talking to on port 80.
    I've never used MAMP, so I don't know how it installs, but it wouldn't surprise me to find that it installs a whole new Apache distribution and you'd need to find that server and its configuration files to fix the DocumentRoot problem, if that's the way you want to go.
    You can also fix it via a simple Alias in the standard Apache configuration - just alias /pixelpost to /Users/whoever/sites/pixelpost - that way users who hit /pixelpost on your server will get the User-specific directory, while all other URLs continue to be served via /Library/WebServer/Documents. This might improve security and avoid the possibility of leaking other content from your home directory that you don't want to make available.

  • Personal Web Sharing Works on One Mac, Not on Other

    I can't get Personal Web Sharing to work with my MacBook Pro. It does work with my iMac. Yes, I can turn it on just fine on the MacBook, by means of System Preferences->Sharing, but I can't successfully use the Personal Web http:// link I see there as a URL in my iMac's browser. When I try, it tells me it can't connect to the host, i.e., the MacBook. When I do the same in reverse, from my MacBook browser with my iMac as target (though the local IP address and the short-user-name are of course different), the connection works fine. 
    I don't think I'm using an incorrect local IP address to try to get to my MacBook. I've checked that. And I do have an index.html file in the appropriate Sites folder on each machine. 
    I'm using Mac OS Leopard 10.5.8 on both machines.
    The problem also shows up on Safari on my iPhone. It can access Personal Web Sharing on the iMac but it can't on the MacBook.  
    I wonder if it's a Bonjour problem? I don't exactly know if Bonjour is running on the MacBook, or how to tell if it is, or how to activate it if it isn't running.
    Or, if it's not Bonjour, what could it be?

    Doug,
    'sudo apachectl start' asked for my password and seemed to have no complaints after getting it. But it didn't tell me anything, and it didn't make a difference.
    After checking out some FAQs at
    http://httpd.apache.org/
    I tried 'apachectl -k start' and got:
    (13)Permission denied: make_sock: could not bind to address [::]:80
    (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80
    no listening sockets available, shutting down
    Unable to open logs
    It made no difference whether Personal Web Sharing was on or off in System Preferences when I did that.
    I do know that the Apache log file is apparently not there where apachectl expects it. I don't understand the other stuff it said, but it looks like maybe it was trying to use an IP address of 0.0.0.0 instead of 10.0.1.16.
    10.0.1.16 is the local IP address of my MacBook.
    I tried 'apachectl configtest' and got 'Syntax OK'.
    I tried moving index.html to /Library/WebServer/Documents -- no help.
    I tried creating a new configuration file in the way you said to try -- no help.
    No matter what I try, I get:
    Unable to connect
    Firefox can't establish a connection to the server at 10.0.1.16.
    I'm beginning to wonder if the Apache environment might not need to be reinstalled. But I'm not sure how. I'm running Leopard 10.5.8, but the original install disk I have is 10.5.1. Software Update moved me up from that to 10.5.8 over time. Your further thoughts and advice will be greatly appreciated ...

  • PERSONAL WEB SHARING ON iMAC G5 WILL NOT START

    hello:
    i am hoping someone would be able to help me on this issue. i attempted to start the Personal Web Sharing service on my computer (iMAC G5 with MAC OS 10.4) from System Preferences > Sharing. however, after i highlight Personal Web Sharing on the list of services and click the Start button, the message changes to "web sharing starting up..." and simply remains that way (i've waited for a long time). it does not change to "web sharing on".
    am i doing something wrong? is it possible that my Apache installation has been compromised? my goal is to be able to use my computer to create and run .php web pages.
    any help / suggestions are greatly appreciated
    iMac G5   Mac OS X (10.4.8)  

    Sorry, this still doesn't seem to be working.
    Actually, it's me steering you wrong. It's been a while since I fooled around with the Entropy PHP installation and it looks like he's changed it.
    He used to put the configuration stuff for PHP at the bottom of the main Apache config file, but now he's putting it in that separate file in the httpd users directory. That's why moving the default Apache configuration file into place didn't help.
    You have two choices: one is to just forget about the PHP5 stuff for now and go with Apple's default PHP install. The other is to try to get PHP5 up and running.
    The first option is very easy: just run this command:
    <pre class="command">mv private/etc/httpd/users/+entropy-php.conf ~/Desktop</pre>That will put the offending file on the desktop. Now try starting the web server. Most likely, PHP won't work yet, but Apache should start. In order to use the default PHP5, you need to make some changes to the httpd.conf file. You can use pico in the Terminal. It's pretty simple and the key commands are printed at the bottom. Where you see the up arrow listed, that means to use the "control" key, i.e., "control"-x to exit. You need to use sudo, though so you have root privileges:
    <pre class="command">sudo pico /etc/httpd/httpd.conf</pre>Search ("control"-w) for "php". The first line you'll see is this:
    <pre class="command">#LoadModule php4_module libexec/httpd/libphp4.so</pre>Uncomment it by removing the "#" from the start of the line. Search again until you find this line:
    <pre>#AddModule mod_php4.c</pre>Again, remove the "#". Now search again until you find these lines:
    <pre class="command"><IfModule mod_php4.c>
    # If php is turned on, we repsect .php and .phps files.
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
    # Since most users will want index.php to work we
    # also automatically enable index.php
    <IfModule mod_dir.c>
    DirectoryIndex index.html index.php
    </IfModule>
    </IfModule></pre>Just verify that they look like these. If they don't, copy and paste your corresponding lines into a reply. Now stop and restart the web server and see if PHP pages will work. You should be using OS X's built-in 4.x version.
    If, on the other hand, you'd rather use the Entropy PHP5 installation, post back and tell me and we'll see if we can figure out what's up with that...

  • MacoBook Pro connecting wirelessly via Personal Web Sharing from iMac G5

    Subject line says it all... more specifically my problem is that some things seem "blocked" on the MBP when i'm connecting wirelessly via my iMac network, but then are 100% functional when I use other wireless networks.
    examples:
    • gmail via Mail.app [mailbox always has the ! symbol and says it's timed out]
    • playing app-based online games, certian functions will not work
    • using FTP software, it won't connect
    Maybe this an issue I can fix with port forwarding, if so how do I go about doing this? I was told my iMac is technically acting as a router, but I don't have a lot of experience with this type of networking. Thanks!

    Personal Web Sharing can be a bit tricky and yes, it's because of the firewall on the Mac that's sharing its connection.
    The actual firewall software in the Mac is completely configurable, but the friendly user interface doesn't support the more sophisticated configurations. Fancier setups would require the use of commandline scripts run from Terminal.
    You'll save yourself a lot of headaches if you buy a wireless base station, and forget about using Personal Web Sharing. A $60 Linksys will do the job nicely.

  • Personal Web Sharing - Don't have permission to access...

    Hi,
    I'm new here so I'm not sure the best place to post my question.
    I posted the question below at the tail end of this discussion:
    http://discussions.apple.com/thread.jspa?threadID=663879&tstart=0
    However, that thread is marked "answered" and my question isn't, so I am re-posting here. Please read the above thread so that you'll know what I already know and have done.
    My question (if you haven't read it at the bottom of that thread):
    I am trying to set up personal web sharing, I have followed all of the above discussion, including Port Forwarding from my router. (I had actually done all of this before searching here, getting instructions from "The Missing Manual: Panther Edition" book.)
    The problem is: when I try to access my shared web pages, I get a "You don't have permission to access..." message.
    I have changed permissions on all files in the (user)/Sites folder (the one I'm sharing) so that "Others" can "Read Only" but still I cannot access these pages from another computer via the internet. I can access them fine from my home computer.
    I know everything is set up correctly and connecting because the remote browser correctly retrieves my computer name (where the shared files are) and port number. It just won't let me in.
    Any help appreciated.
    thanks,

    braintrino,
    I'm not sure how to make sense of your statements.
    The situation with FileVault is conceptually simple. The contents of a FileVault user's home directory are on an encrypted disk image. When the user logs in from the login window, that image is mounted (using their home directory path as the mount point); when they log out, the image is unmounted. Note that logging in via ssh doesn't cause the system to mount their home directory...
    So, when a user is logged in, Apache can (if normal UNIX permissions permit it) see their ~Sites folder and serve pages. When the user is logged out, Apache can't.
    I suppose that a FileVault user might be able to get around this, if they don't mind leaving their ~Sites folder unencrypted... They could create a folder outside of their home directory (e.g., /Users/Shared/braintrinos_site/) and put their Web pages there; log into their account and replace their ~Sites folder with a symbolic link to their Web page directory; log out, then ssh in and add a symbolic link from their home directory to their Web page directory. Then, whether they're logged in or not, Apache should be able to see a symbolic link from ~Sites to the unencrypted Web page directory.

  • PERSONAL WEB SHARING - ANYONE HELP!!!

    My goal is to setup personal web sharing for my mac mini. My intent was to check out my web page design from the internet (just because I could), but now it's changed to wanting to prove that I can conquer this (for my own pride).
    Here's my setup: Cable internet (Cox Communications), Airport Express, Mac Mini.
    I have put the web page into the /library/webserver/documents folder. I have forwarded port 80 on my router to my local IP address. I don't have my firewall up at this point.
    The scenario is as follows: I can access my webpage using my public IP address only on my local area network. If I go to work, I cannot access the page. If I go to my friend's house, I cannot access my page.
    I've read countless forums in search of an answer to this dilema. I have talked to Cox about blocking port 80 (which they don't). I have now spent the better part of the day talking to Apple about this problem. They concluded that I was smart enough to set up everything correctly, but were just as stumped as I was in trying to solve the problem.
    So, they directed me to this forum. If anyone has any ideas on how to fix this problem, I'm all ears. I'm willing to try pretty much anything to get this to work (my pride depends on it).

    I know it may seem like this issue has been answered, but this forum seems to be the closest place for me to report on my very similar situation and see if there is a solution, if not the same one offered by Charlie, above, perhaps some other insight into the nature of this problem, and its resolution.
    BACKGROUND and OBJECTIVE:
    Like MacDaddy, I am trying to set up a personal web sharer on my iMac G5. I started out yesterday with the goal of setting up an FTP server, because I want others to be able to download very large video files (500 MB to 2 GB). I subscribed to .Mac and I tried this on an iDisk, but I soon learned that the upload times were so "painfully slow," as others have also reported, that I decided to try to let people grab the files directly from my own hard disk. In theory, the Mac is equipped to allow this to occur, right?
    I couldn't get the FTP server setup to work, because access was denied, so I decided to shift my effort to creating a personal web server and create pages to files that could be downloaded.
    SET-UP:
    I use Adelphia Communications as my Internet Service Provider, and I get a dynamic Internet address, which has not changed since I began this process and which, says Adelphia tech support, is not designed to change until and unless I disconnect from their system. I have a small home network, hard-wired and connected through LinkSys BESFR41 router. I created a test home page with a couple of links; the web pages are located in the default ~username/Sites folder.
    I know the difference between the 192.168.x.x addresses generated by the router to identify the computers on the network from the 24.49.xxx.xx IP address provided by Adelphia. I learned how to do the port forwarding for the router so that the iMac, which is identified as 192.168.1.102 on the network, should get the HTTP incoming traffic on port 80.
    Here is a web page containing links to the screen captures that will illustrate what I've selected in regards to:
    • Sharing Preference
    • Firewall Preferences
    • Router status setup
    • Router Port Forwarding setup
    http://home.adelphia.net/~jmbattaglia/personalwebsharer/index.html
    Also, I understand that the correct format for the URL to be given to my friends goes like this:
    http://[IP_address]/~short name of user's account]/
    So, this is how I have used it in my situation:
    http://24.49.xxx.xx/~JohnMichaeliMacG5/
    Also, I've learned that, for one computer on the network to bring up the personal web server pages in its browser, I should use this format:
    http://192.168.1.102/~JohnMichaeliMacG5/
    where, as I mentioned, the iMac G5 has been assigned the internal network address of 192.168.1.102.
    I think I've got everything right, but I'm willing to be corrected in order to get this thing to work properly.
    RESULTS:
    Like MacDaddy reported, I can successfully access my test web page internally on my private home network. This means that I can access the web page on the iMac G5 when I key in either the 192.168.1.102 format, or when I use the 24.49.xxx.xx format, in a web browser on my PowerMac G4.
    Similarly, I can access my test web page when I use the 24.49.xxx.xx format in a web browser on my iMac G5 itself.
    However, no one else from the outside world can see my pages! That's the problem which MacDaddy reported, and that's the mystery I cannot understand.
    Spurred by the insights of this forum, I contacted Adelphia and I asked them if the HTTP port (80) and the FTP port (21) was blocked. The tech support insisted with absolute certainty that those ports were open and that all ports (up to a very high number) were open. I pushed him hard on it, and he consulted an internal Adelphia document which listed the closed ports, and the ones I am interested in were not closed.
    He referred me to Apple, which wanted me to either to upgrade my service warranty contract, or pay $49 to ask a question that they would not guarantee they could answer. I passed on that option, and decided to post my question here, where there may be some resolution on a problem that may be preventing many of us from realizing the full potential of our machines.
    SOLUTIONS:
    I have not tried to implement the solution that Charlie offered to MacDaddy, which apparently made him a happy camper , because I have no reason to doubt the Adelphia tech support person who resolutely assured me that port 80 is not blocked. If no one can offer any alternative insight into this problem, then perhaps I will have to try Charlie's suggestion out.
    But I just thought I'd post my situation, in case someone else can explain what the heck is going on here and suggest an easier fix. It is unfortunate that something which should have taken a few clicks of the mouse to set up has turned out to be a complicated technical adventure over a twisting, winded path lasting over two days, but that's what's happened. Can anybody straighten this path out? Thanks.

  • Is there an FAQ or step by step tutorial for personal web sharing?

    First off, if anyone knows of an FAQ somewhere that answers this question, post me the link.
    Am trying to build a comon web page for synching iCal on a stans alone machine and am sure this is a very common question from new iCal users like myself:
    Situation:
    -Multiple users on same iMac
    -Different accounts Mom, Dad, Kids, Nanny
    -Need to collaborate schedules
    Want to create a webpage on my machine (without .mac) where we can publish calendars.
    Tried turning on personal web sharing in the system preferences but the addresses listed only show a page listed as "Access Forbidden."
    Is there a step by step tutorial out there? I could really use one.

    Thanks to all for replying. The information posted was very informative and answered my questions asked.
    I guess the real answer for me the very novice and deliberatly blissfull user is: No.
    I switched to Mac after assembling my own PCs to try and get then to do what I wanted. The driver/dll/ini issues were maddening!!!
    Am not tech-phobic, but am loathe to start working in the terminal and with code since I know so little and it was that commercial that said "I got tired of being my own tech dept." that made me switch.
    Looked at the tutorials and there are always comments underneath with comments about how there is a typo here, mispelling, there, better code over yander etc. linux/apache/unit/windows flame wars etc.
    All I want it to do is work or not. Since it is not; will find another way.
    Between purusing sites I think I came up with a simple low tech solution.
    In the shared folder create an iCal_Shared folder. From one user export a calendar complete with a date. For example Dad's work as of 15 JAN. Then in the duaghter's calendar import the same calendar. Knowing that as changes are made by me, I will have to update the exported file, and my daughter will have to be aware of the as of dates.
    A lot of solutions out there are for the corporate world. Am happy to Apple gaining market share but I am on a stand alone machine.
    The iPhoto manager is a great product from a third party and was happy to pay for it. Saves me a lot of time with 20K+ pictures.
    Just want an app causing iCal to behave simply, ie my daughter and I could share calendar information on our machine without running WebDAV server, a three tiered digital satelite hookup, etc,
    Pie Argh Squarred..It seems to me that Apple woule be better off if they came up with solutions like that that cost $20 since they would reach a lot more people than they are now with the $100 annual .mac extortion fee.
    Kudos to those of you who are much smarter and braver than I and again I thank you for your posts as they have opened my eyes as to just how old I am getting! Perhaps my daughter should solve this one for me!

  • Personal Web Sharing - Just the "Sites" folder?

    So I have just turned personal web sharing on. I am going to use this feature to send zip files. (or let people have access to zip files in my Sites folder)
    But my question is, what else can someone see from the IP address I give out? Pictures folder? Applications? Music? or is personal web sharing limited to only the "Sites" folder?
    I am totally new to this so I know it's a basic question, but I couldn't find the answer anywhere else. Thank you.

    By default, Apache will make available the Sites folder in account home folders, and the folder /Library/WebServer/Documents/ when no username is specified in the URL.

  • Personal Web Sharing

    So I fire up ol' Personal Web Sharing, and it works fine for localhost. When I try to access it from the ip & name string I get a 403 forbidden error. I've done the "Get Info" and verified my permissions are correct. Still happens. According to Apple Tech Support, "...we can't help you fix it. There's nothing in our database about that."
    I've also used the disk utility to rebuild permissions, and restarted the server via the terminal interface - both to no avail.
    Any ideas would be greatly appreciated.
    BTW...I'm new to Mac, so if suggesting I investigated files such as .ini. or .conf, please include their paths. I can't seem to find the native install - apache folder.
    Thanks in advance for the help.

    This posting on another thread has some good suggestions that might tell us more about what's going on. The first suggestion is to check the Console for error messages, which might show what's happening when you try to bring up your website either locally or from another computer. The other thing is to check apache's configuration using a Terminal command. Read this posting for more details:
    http://discussions.apple.com/message.jspa?messageID=1956252#1956252
    If the problem comes down to an Apache configuration issue, I found this free app that might make configuring Apache easier than using a text editor. It's called WebControl 1.0.7 and you can download it from here:

  • Personal web sharing not working anymore. localhost

    I've had my personal web sharing working fine for some time now. I've been using it to develop PHP sites and such locally. I recently added a local version of wordpress and just now restarted the server by opening my sys prefs and going into sharing and clicking "web sharing" off and then back on in order to restart it. After doing that I can't access my localhost sites. I get this message "Safari can’t connect to the server." when clicking on either of the two links displayed in web sharing pref.
    Any thoughts on what is going wrong here?

    anyone?

  • Personal Web Sharing Questions

    I have started Personal Web Sharing in the Sharing System Preferences. I have used a PC off site and entered the address shown in the Preference window. I get an error window and cannot access the index.html file in the Sites folder.
    My computer is on the internet via a cable modem to Airport Express and access to Airport requires a password (Wep key).
    Does that have anything to do with the problem?
    What are the variables I might be overlooking?
    thanx

    I have quoted from an article by PChuck, I think he wrote it in very understandable terms.
    In general, only open ports when necessary. When an application, running on a client computer on your LAN, wants to communicate with a server outside the LAN, it sends a packet out. The NAT router does, in sequence:
    1. Open a port which points back to the client computer that sent the packet.
    2. Sends the packet to the distant computer, giving its IP address, and the port that was just opened.
    3. Waits for a return packet from the distant computer.
    4. Forwards the return packet from the distant computer to the client computer that started the whole thing.
    NAT is stateful. This is a reason why a NAT router is said to provide protection like a firewall, but it is not. The port that is opened, from the outgoing packet, only responds to the address of the distant server. Thus when a port is opened, only replies from the distant server will be returned to the client computer on the LAN. Packets from any other computer, to that port, simply get dropped by the NAT router.
    NAT, in its purest form, only supports client computers. Unless a client computer opens a port with an outgoing packet, no incoming traffic gets passed, by a NAT router, to any LAN computer.
    So how do you use a server (a computer that waits for unsolicited incoming packets) behind a NAT router? Before UPnP, you would use either port forwarding, or port triggering.
    • With Port Forwarding, you define fixed ports, to be forwarded to a fixed IP address. Those ports are opened when they are defined, and stay opened forever. The ports must be defined, and opened, before they are needed.
    • With Port Triggering, you define fixed ports, to be forwarded, when specific other ports are opened, by any application on any computer. Those ports are opened when triggered, and stay open forever. The ports must be defined before the triggered port is needed.
    • With UPnP, the UPnP capable application tells the router, precisely when needed, what ports are to be opened, and fowarded to what (potentially dynamic) IP address. And properly written UPnP applications will also tell the router when to close those ports.
    Many well meaning security experts see UPnP as a security risk. If you have uncontrolled applications running on your computer, they can control your router, have it open ports at will, and create security risks.
    If your computer has uncontrolled applications running on it, you've already lost that battle. You need to learn about how to get rid of any existing untrustable software, and then you need to learn about keeping any future untrustable software off your computer.
    UPnP is just as reliable, and as safe, as any applications running on your computer. If you control your computers properly, and ONLY trusted applications run on them, UPnP is perfectly safe. If you don't control your computers properly, applications hijacking UPnP to open holes in your router will be the least of your worries.
    UPnP is actually more secure when your computers can be trusted. UPnP, as I state above, will dynamically instruct the router to close specific ports when they are not needed. Port forwarding, and port triggering, leave ports open forever.
    The other advantage of UPnP is that it allows you to have servers on your LAN, using dynamic IP addressing. Port forwarding requires a server to have a fixed IP address. Port triggering, depending upon the NAT router, may or may not require a server to have a fixed IP address.
    • With port forwarding, or port triggering, you can have only a single computer on the LAN running a given server application. A pre defined port can be forwarded to only one server.
    • With UPnP forwarding, multiple computers can run the same UPnP compliant application, such as an IM program. The server application can negotiate with the router, as necessary, and have the port forwarded.
    Bottom line? A properly written UPnP capable application is more functional, and no less secure, than an equivalent non-UPnP capable application. On a LAN with a properly designed layered security strategy, it will not create a security risk.

  • Personal Web Sharing on 10.4.8

    I have read other topics about this, but couldn't find any that help me.
    My problem is this - when I click on Start (for Personal Web Sharing) in the Preferences app, the service never starts. When I open terminal and enter -
    cd /etc/httpd/
    ls -l httpd.conf
    I get -
    -rw-r--r-- 1 root wheel 38414 Nov 23 09:27 httpd.conf
    When I enter apachectl start, I get this -
    fopen: Permission denied
    httpd: could not open error log file /private/var/log/httpd/error_log.
    /usr/sbin/apachectl start: httpd could not be started
    When I look at my account in PREFERENCES : Accounts, I see it as an Admin account.
    What the heck is wrong? Any ideas?

    And, by the way, you're absolutely right about the
    two versions of PHP - I upgraded to 5.0x, and that's
    when the trouble started!
    I made that exact mistake and that's exactly what happened to me too.
    The following lines, which are found in the file /etc/httpd/httpd.conf had to be uncommented to make PHP work:
    LoadModule php4_module libexec/httpd/libphp4.so
    AddModule mod_php4.c
    I don't know if recommenting them (putting a #) in front of them) will work for you; when I installed PHP 5 on top of PHP 4 I eventually wound up having to reinstall the OS ( I mean, there's a reason I don't tamper around with it much).
    I may some time soon try upgrading, but for now I'll hang with PHP 4; it works.

  • Apache2 & personal web sharing

    I have installed apache 2.2.8 and on http://127.0.0.1/ and http://localhost/ the browser is serving /usr/local/apache2/htdocs/index.html but:
    1. personal web sharing just hangs waiting when I click Turn On PWS
    2. http://127.0.0.1/~macuser/ does not bring up an index.html I placed there (in /Users/macuser/Sites/ )
    I am not sure what did I do wrong, as I am not a code guy and new to this
    I run the whole compile and install process several times because it did not work and in the process I had removed the default apache 1.3 that was installed and working
    It also seems like my system startup time is significantly longer than before the apache2 installation.
    when I run sudo /usr/local/apache2/bin/apachectl start in terminal it says "already running" although sys pref would not show personal web sharing is on
    I am not sure how is this all related but all I want is to be able to serve pages via apache from my Sites directory
    any ideas would should I check for?
    PPC 10.4.11
    Thanks

    is fairly easy to remedy this,
    Edit the httpd.conf which is in the apache2 directory you have created.
    Once open (i'd recommend BBedit but txt edit will do just make sure it doesn't save the file to rich text)
    search down the httpd.conf file untill you find ;
    # PidFile: The file in which the server should record its process
    # identification number when it starts.
    and change it too
    #<IfModule !mpm_netware.c>
    PidFile /private/var/run/httpd.pid
    #</IfModule>
    I'm afraid you'll have to get a bit developer as the next section is in the terminal;
    open up the terminal and in a new shell Apple Key + N;
    first type; sudo
    Then Your password if your admin: your password
    Then : cd /usr/sbin/;
    Then: mv apachectl apachectl-1.3;
    Then : ln -s /apache2/bin/apachectl apachectl;
    You'll now be able to stop and start web serving from your system preference pane;
    You should also modify httpd.conf with the following (however this isn't essentila just to switch it on from system prefs)
    change user and group to:
    User www
    Group www
    You may also need to change owner of the httpd.conf in the terminal file to edit it.
    sudo chmod -R 777 ((drag your apache directory here))
    all done

  • I had CS4 on my iMac desktop (two users) but my hard drive completely crashed. We bought two new Macbook Pros (one for me and one for my daughter) but CS4 didn't transfer over. The iMac is totally dead so we can't deactivate it there.  My daughter is head

    We had an iMac with CS4 and the hard drive finally crashed. My daughter and I were both users on that computer.  We purchased two new macbook pros and had the data transferred but CS4 didn't come over. The iMac is totally dead so we can't deactivate anything from it. She is heading off to college soon and eventually will need to upgrade but for now CS4 is just fine. I also need it on my computer.  Help??
