Is it my opinion, or Unix & Linux systems dislike me????

New problem

I want to mysqldump a database from a Red Hat 9 mysql server,
to a Solaris 7 mysql server.

the problem is :

Mysql server in Red Hat 9 is up and running. (Its the production server).
I'm trying to mysqldump a database, and provides me the below error.

/usr/local/mysql/bin/mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) when trying to connect

Remember, this server is up and running.

I'm searching everywhere for mysql.sock, or *.sock, and I can't find anything.
there is no mysql.sock file in the system (hidden or not).
There is no .sock file in the system.

mysqld.log it exists but is empty, so I can't get any information from there.

Now,

in Solaris 7, mysql.sock exists, in a proper location '/tmp/mysql.sock',
but its empty.
Mysql server, in Solaris 7, its also up and running.

My obvious question is , how to make mysqldump work without any mysql.sock file in the system????

But I want to add another question.
If I'll create, in Red Hat 9, a '/tmp/mysql.sock' file, empty of course, will it cause any damage to the mysql server, which is up and running????????

Thanks again.

I'll never give up, never give in
