Error during initial setup for Cacti

[danielnwa]

When I am installing cacti, i get this error right after I clicked next from the installing process. And when I went back to http:/localhost/index.php, the login in page appears but I can't log in with the cacti user I created from mysql. Help anyone???

Below is the error that I got.

The default login for cacti is
user name -> admin
password -> admin

Cacti will prompt you to change the password on your first login

The warnings you are receiving are due to the default scripts cacti is configured to run for local host. These scripts are for a unix/linux host and will fail if run on a w32 host.

And when I went back to http:/localhost/index.php, the login in page appears but I can't log in with the cacti user I created from mysql.

I'm not quite sure what you mean by this, could you provide a little more detail. What user did you create from mysql?

Thank you Phil,

I logged in with admin and pwd admin after searching the forum. Thanks though.
You mentioned that the warnings are due to Unix/Linux default. I am getting this error now when trying to set up localhost monitoring.

Warning: exec() [function.exec]: Unable to fork [ -v2c -t 1 127.0.0.1:161 "My Community String" .1.3.6.1.2.1.1.1.0] in C:\cacti\lib\snmp.php on line 219
SNMP error

Is this because of the Unix/Linux default also? If so, can you explain how I can fix this? Thanks

Did you enable SNMP support in PHP?

I am having the same problem

Warning: exec() [function.exec]: Unable to fork [ -O vt -c "string" -v 2c -t 1 -r 3 IP:161 .1.3.6.1.2.1.1.3.0] in C:\Apache\htdocs\cacti\lib\snmp.php on line 74

and yes SNMP is enabled in PHP

Hi,
The fork command in the warning message seems to be missing the executable (should appear just before "-v2c"). Check the settings page / path tab to be sure you've specified paths to rrdtool and the net-snmp exes.

Another common issue with fork (exec() and system()) is that a standard windows 2k / XP installation sets specific permissions on the file %windir%\system32\cmd.exe to prevent execution by an anonymous IIS user. Big security hole not-withstanding, you will need to set permissions on this file to enable IUSR_<host> (or whatever your anonymous user account is) to read and execute the cmd.exe file (exec() works by firing up cmd.exe and passing it the desired string).

Hope this helps.
