===Determine Your Virtuoso Server's HTTP/<nop>WebDAV and SQL Ports===

There are at least two means that you may employ to determine the ports used by Virtuoso Universal Server for SQL and HTTP/<nop>WebDAV:

**virtuoso.log**

1. Log into the machine that contains your Virtuoso Universal Server.
2. Use a text editor to open the virtuoso.log file that appears in the db sub-directory of your Virtuoso installation.
3. Locate the entries that pertain to the last startup of the Virtuoso Universal Server.
4. Look for entries similar to the following:

{{{
01:12:07 HTTP/WebDAV server online at 8890
01:12:07 Server online at 1111 (pid 264)
}}}

**virtuoso.ini**

1. Log into the machine that contains your Virtuoso Universal Server.
2. Use a text editor to open the virtuoso.ini file that appears in the db sub-directory of your Virtuoso installation.
3. Locate the [Parameter] section.
4. Locate the <nop>ServerPort parameter. This parameter passes your SQL port. For example:

{{{
;
;  Server parameters
;
[Parameters]
ServerPort               = 1112
}}}

5. Locate the [HTTPServer] section.
6. Locate the <nop>ServerPort parameter. This parameter passes your HTTP/<nop>WebDAV port. For example:

{{{
[HTTPServer]
ServerPort                  = 8890
}}}
