CHAPTER TWO - COMMON PROBLEMS

2.1) SOLUTIONS TO COMMON PROBLEMS

2.1) SOLUTIONS TO COMMON PROBLEMS

2.1.1) Access logs

"I can't find my access log!"

 They are located at /etc/httpd/domlogs/yourdomain.com. So, the access log for snoopy.com is in /etc/httpd/domlogs/snoopy.com. You can link that file to a file in your directory structure, so that you may view it thru your browser. This log file is severely analyzed through all the control panel statistics programs, so hard viewing of the file is not really needed.

2.1.2) Error logs

"I can't find my error log?"

 Use the built in Error Log Report in the Analog statistics program in your browser control panel.

2.1.3) Cgi-bin scripts

"Where do I put my cgi-bin scripts?"

 Put them in the subdirectory cgi-bin which should be under your public_html directory. You may then call them thru a browser as http://www.yourdomain.com/cgi-bin/your.cgi

 "I don't have a cgi-bin directory!"

 Make it by typing mkdir cgi-bin while in your public_html directory.

 "How do I access cgi-bin scripts in the cgi-bin directory?"

 If your domain name is bart.com, and the script itself is called your.cgi, access them as http://www.bart.com/cgi-bin/your.cgi.

 "Hey! /cgi-bin/ doesn't work for me!"

 Ask us to activate your cgi-bin directory.

2.1.4) Perl scripts

"I am being told file not found"

"I am being told No such file or directory"

Upload your Perl script in ascii mode, not binary mode.

Use rz -a for telnet users, or the ascii mode for ftp users.

Sometimes it seems like this is asked about once a day, so we're going to repeat it, loudly.

Upload your Perl script in ascii mode, not binary mode. Use rz -a for telnet users, or the ascii mode for ftp users. 

"I get errors such as Literal @sdfsdf now requires backslash at ./test.rob line 2, within string Execution of ./test.rob aborted due to compilation errors." Place a "\" before such offending @ characters. This is an incompatibility between Perl 5 and Perl 4.

Alternatively you could change the first line in your Perl program from #! /usr/bin/perl to #! /usr/bin/perl4. The correct path to perl is /usr/local bin/perl OR /usr/bin/perl. Both usually lead to access to Perl, however, try changing it if your script is not working.

2.1.5) Image Maps

"Hey! my image maps don't work!"

 This is a proper imagemap reference:
    <a href="djonly.map"><img src="djonly.gif" ISMAP> </A>

Possible mistakes:

  • You didn't use NCSA format.
  • Instead of saying djonly.map, you included your domain name or other information in your reference. (Sometimes causes problems.)
  • You forgot to use the extension .map.
  • You forgot the word ISMAP.
  • You forgot to include the default line as the first line in your image map.
  • When specifying rectangles, you didn't include the small numbers first, as in 0,0 100,100.
2.1.6) Anonymous FTP
"Where should I store files for anonymous ftp access?"

 Put files in the directory named public_ftp in your root directory. This will allow a file to be accessed by a customer with ftp://yourdomain.com/yourfile.

2.1.7) Setting permissions
"Hey, how do I change permissions on a file or folder?"

Go to the File Manager, and select the file. There will be an option in the uppoer right hand corner to change permissions. Select the permissions you want to set, and submit.

The permissions of a file or directory are: r=read access, x=execute access, w=write access. The owner boxes apply to you, the group ones apply to your group- most people don't use this feature except on larger site- and the last group applies to everyone else. Execute access enables you to run programs or enter directories.

2.1.8) Post not implemented "I am getting the message 'POST not implemented'. Help!"

You probably are using the wrong reference for cgiemail. Use the reference "/cgi-sys/cgiemail/mail.txt" Another possibility is that you are pointing to a cgi-bin script that you have not put in your cgi-bin directory. In general this message really means that the web server is not recognizing the cgi-bin script you are calling as a program, it thinks it is a regular text file.

2.1.9) Don't have permission to access /
This error message means that you are missing your index.htm (...or index.html) file.

Note that files that start with a "." are hidden files. To see them, type ls -al.

2.1.10) MS Frontpage Publish Errors
"I am having problems publishing with MS Frontpage. It will not accept my login, and seems to just hang there...?"

 Email support@jjswebdev.com and ask them to reinstall the Frontpage extensions and the FP Email extensions..

2.1.11) Email is Disappearing
"I seem to not be getting my email?"

 Make sure to check your default email login pop. Double check to see where your default email is being sent to thru the control panel. Make sure you do not have a pop and a forwarder for the same email address, for you can only choose one or the other, not both. Make sure that you do not have a pop or forwarder set up for that email address that you forgot about.

2.1.12) Cannot Log into Email POP3 Account

Email support@jjswebdev.com and ask them to run fixpop and ln -s /usr/local/etc/cpanel/bin/popsh /bin/pinesh. Send them email address, username, and password to all pop accounts you need corrected.

2.1.13) My Domain Name Does Not Work

Check "http://www.tracert.com/cgi-bin/ping.pl with your domain name, and see if it is accessible for the servers included there. If it is being found by the large majority of servers there, than there is something wrong with your ISP's DNS, or someone on the backbone between HostForWeb and your ISP. We can do nothing in this situation, and you must wait for the error to correct itself. If the domain name is not being found, please check the InterNIC Registry to see if your domain name registration/transfer has been completed. If it has NS1.JJSWEBDEV.NET & NS2.JJSWEBDEV.NET on the bottom of the registration, then the transfer is completed. If it has different name-servers mentioned there, or no registration appears at all, the domain name is not transferred/registered yet, and you must wait for such. Transfers/Registration take normally 24-72 hours. If your registration says "On Hold", then you have not paid your InteNIC domain registration fees, and they have shut down access to your domain.
