DoIt()

void XrdCmsBlackList::DoIt ( )

Time driven method for checking black list file.

Implements XrdJob.

Init()

static void XrdCmsBlackList::Init ( XrdScheduler *  sP, XrdCmsCluster *  cP, const char *  blfn, int  chkt = 600  )

static

Initialize the black list

Parameters

sP	Pointer to the scheduler object.
cP	Pointer to the cluster object.
blfn	The path to the black list file or null.
chkt	Seconds between checks for blacklist changes. If the value is negative, the blacklist is treated as a whitelist.

Present()

static int XrdCmsBlackList::Present ( const char *  hName, XrdOucTList *  bList = 0, char *  rbuff = 0, int  rblen = 0  )

static

Check if host is in the black list and how it should be managed.

Parameters

hName	Pointer to the host name or address.
bList	Optional pointer to a private black list.
rbuff	Pointer to the buffer to contain the redirect response. If nil, the host is not redirected.
rblen	The size of rbuff. If zero or insufficiently large the host is not redirected.

Returns

< -1 Host is in the black list and would be redirected; but either rbuff was nil or the buffer was too small. The abs(returned value) is the size the buffer should have been.

= -1 Host is in the black list and should not be redirected.

= 0 Host not in the black list.

> 0 Host is in the black list and should be redirected. The return value is the size of the redirect response placed in the supplied buffer.
