The vCenter VAMI service must restrict the ability of users to launch Denial of Service (DoS) attacks against other information systems or networks.

| Description | ||||
| In UNIX and related computer operating systems, a file descriptor is an indicator used to access a file or other input/output resource, such as a pipe or network connection. File descriptors index into a per-process file descriptor table maintained by the kernel, which in turn indexes into a systemwide table of files opened by all processes, called the file table. As a single-threaded server, Lighttpd must be limited in the number of file descriptors that can be allocated. This will prevent Lighttpd from being used in a form of DoS attack against the operating system. | ||||

Check Text (C-259149r935351_chk)
At the command prompt, run the following command:
# /opt/vmware/sbin/vami-lighttpd -p -f /opt/vmware/etc/lighttpd/lighttpd.conf 2>/dev/null|grep "server.max-fds"
Expected result:
server.max-fds=2048
If the output does not match the expected result, this is a finding.
Note: The command must be run from a bash shell and not from a shell generated by the "appliance shell". Use the "chsh" command to change the shell for the account to "/bin/bash". Refer to KB Article 2100508 for more details:

Fix Text (F-62798r935350_fix)
Navigate to and open:
/opt/vmware/etc/lighttpd/lighttpd.conf
Add or reconfigure the following value:
server.max-fds = 2048
Restart the service with the following command:
# vmon-cli --restart applmgmt
