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 in your home directory, this is the directory you are in when you first log-on.

2.1.2) Error logs

"I can't find my error log?"

We don't keep error logs for performance reasons.

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 www 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.

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.

"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

2.1.5 Anonymous ftp

"Where should I store files for anonymous ftp access?"

Put files in the directory named anonftp. This will allow a file to be accessed by a customer with ftp://yourdomain.com/pub/file.

2.1.6) Setting permissions

"Hey, how do I stop people who are not in my group from reading a directory?"

Type chmod o-r directory while you are in the directory above it.

"I don't care if people in my group can read my directory, but I don't want them to write in it!"

Type chmod g-w directory while you are in the directory above it.

"Who is in my group?"

In general, each domain has its own group. If you find you are in the group users, let us know if you wish for your domain to have its own group.

"Tell me more about permissions, they sound neat!"

To list the access permissions of a file or directory, type ls -ls *. r=read access, x=execute access, w=write access. The first three letters apply to you, the second three letters apply to your group, the last three letters apply to everyone else. Execute access enables you to run programs or enter directories.

Examples of using chmod:

    PEOPLE                                    PERMISSIONS

    u = the file's user (or owner)            r = read access

    g = the file's group                      x = execute access

    o = others                                w = write access

    a = the user, the group, and others.



    chmod a+w =  let everyone write to the file

    chmod go-r = don't let people in the file's group or others to read

                 the file

    chmod g+x =  let people in the file's group execute the file

2.1.7) 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-bin/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.

2.1.8) Don't have permission to access /

This error message means that you are missing your index.html file.

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

If you wish to ftp this file in, go to the /home/oceania directory assuming your userid is oceania.
