If that's what you've been doing, could you try again with the correct command name and see what happens please ?

If you have been typing it correctly then your system must be quite badly damaged or missing some very fundamental binaries, since the ls command is pretty much as common as it gets on any UNIX-style system.
You are right. I was doing it wrong. It did look like a 1 to me...so this is what I got:
Code:
[root@dedicated ~]# ls -l /proc/4600
ls: cannot access /proc/4600: No such file or directory
[root@dedicated ~]# ls -l/proc/4600/fd
ls: invalid option -- '/'
Try `ls --help' for more information.
[root@dedicated ~]# ls -l /proc/4600/fd
ls: cannot access /proc/4600/fd: No such file or directory
[root@dedicated ~]# ls -a

Tech support got back to me last night said it was a brute force attack (?) and that my install of "ban to fail" stopped it. But to me it looks as if it was run from "inside my computer". It slowed the server down to a crawl. also legitimate emails have stopped being able to send to comcast, Verizon, yahoo,etc. Have contacted them but they say we are not on their black list. Just can't figure this out. I have a minimal tech support package so they say "You have this....and you need to do this....good luck....Oh and by the way you can upgrade for $$$".

Apache::TestConfig(3)					User Contributed Perl Documentation				     Apache::TestConfig(3)

NAME
Apache::TestConfig -- Test Configuration setup module SYNOPSIS
use Apache::TestConfig; my $cfg = Apache::TestConfig->new(%args) my $fh = $cfg->genfile($file); $cfg->writefile($file, $content); $cfg->gendir($dir); ... DESCRIPTION
"Apache::TestConfig" is used in creating the "Apache::Test" configuration files. FUNCTIONS
genwarning() my $warn = $cfg->genwarning($filename) genwarning() returns a warning string as a comment, saying that the file was autogenerated and that it's not a good idea to modify this file. After the warning a perl trace of calls to this this function is appended. This trace is useful for finding what code has created the file. genwarning() automatically recognizes the comment type based on the file extension. If the extension is not recognized, the default "#" style is used. Currently it support "<!-- -->", "/* ... */" and "#" styles. genfile() my $fh = $cfg->genfile($file); genfile() creates a new file $file for writing and returns a file handle. A comment with a warning and calls trace is added to the top of this file. See genwarning() for more info about this comment. If parent directories of $file don't exist they will be automagically created. The file $file and any created parent directories (if found empty) will be automatically removed on cleanup. writefile() $cfg->writefile($file, $content, [$nowarning]); writefile() creates a new file $file with the content of $content. A comment with a warning and calls trace is added to the top of this file unless $nowarnings is passed and set to a true value. See genwarning() for more info about this comment. If parent directories of $file don't exist they will be automagically created. The file $file and any created parent directories (if found empty) will be automatically removed on cleanup. write_perlscript() $cfg->write_perlscript($filename, @lines); Similar to writefile() but creates an executable Perl script with correctly set shebang line. gendir() $cfg->gendir($dir); gendir() creates a new directory $dir. If parent directories of $dir don't exist they will be automagically created. The directory $dir and any created parent directories will be automatically removed on cleanup if found empty. AUTHOR
