CHAPTER Nine - COMMON PROBLEMS

SOLUTIONS TO COMMON PROBLEMS

SOLUTIONS TO COMMON PROBLEMS

 

Access logs(back to top)

"I can't find my access log!"

They are in /www/logs/. So, the access log for snoopy.com is in /www/logs/snoopy-access-log.

 

Error logs(back to top)

"I can't find my error log?"

We don't keep error logs for performance reasons. It's likely that what you might have used your error log to check on can be done another way. Ask support@springweb.com if you'd like help.

 

Cgi-bin scripts(back to top)

"Where do I put my cgi-bin scripts?" Put them in the subdirectory cgi-bin which should be under your www directory.

 

"I don't have a cgi-bin directory!"

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

 

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

If your domain name is bart.com, access them as

http://www.bart.com/cgi-bart/script_name.

 

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

Ask us to activate your cgi-bin directory.

 

Perl scripts(back to top)

"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 torepeat 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(back to top)

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

 

Imagemaps(back to top)

"Hey! my imagemaps don't work!"

This is a proper imagemap reference:

<a href="djonly.map"><img src="djonly.gif" ISMAP> </A>

 

Possible mistakes:

 

Anonymous ftp(back to top)

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

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

At your request we can shorten the anonymous directory to ftp://your_name/file. Let us know if want this.

 

Setting permissions(back to top)

"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:(back to top)

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

 

Post not implemented(back to top)

"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.

Another possibility is that you have not asked us to activate your cgi-bin directory. In general this message really means that the web server is not recognizing he cgi-bin script you are calling as a program, it thinks it is a regular text file.

 

Don't have permission to access /(back to top)

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.
