Okay i was able to get the checksum of the files of the directory and sub directories..how do I get the list with the checksum and the file permissions and dates in the same file...now this is driving me crazy...can anyone help me with this ? ls -ltraR + checksum to a file
Dear All
I have written a client server program for file transmission from one system to other using UDP.
Can i use the cksum number in the udp header to validate if the received packet is corrupted or not? If yes, how can i extract the header and validate it..
Also is there any way that... (3 Replies)

Hi, I am creating a ksh script to search for a string of text inside files within a directory tree. Some of these file are going to be read/execute only. I know to use chmod to change the permissions of the file, but I want to preserve the original permissions after writing to the file. How can I... (3 Replies)
Hi All,
I have spooled some data in a file (a.dat, b.dat etc..) and after that I want to get the size and checksum of spooled file (a.dat, b.dat etc..) in a log file(file_info.log).
By the way I dont want lost the previous output file info(Append data).

Hi All,
I am trying to print the dates that falls between 2 date variables into a file. Here is the example.

Output to file abc.txt should be : 20120613,20120614,120120615,20120616
Can you pls help me accomplish this in LINUX.

DESCRIPTION
The krb5_checksum structure holds a Kerberos checksum. There is no component inside krb5_checksum that is directly referable.
The functions are used to create and verify checksums. krb5_create_checksum() creates a checksum of the specified data, and puts it in
result. If crypto is NULL, usage_or_type specifies the checksum type to use; it must not be keyed. Otherwise crypto is an encryption context
created by krb5_crypto_init(), and usage_or_type specifies a key-usage.
krb5_verify_checksum() verifies the checksum against the provided data.
krb5_checksum_is_collision_proof() returns true is the specified checksum is collision proof (that it's very unlikely that two strings has
the same hash value, and that it's hard to find two strings that has the same hash). Examples of collision proof checksums are MD5, and SHA1,
while CRC32 is not.
krb5_checksum_is_keyed() returns true if the specified checksum type is keyed (that the hash value is a function of both the data, and a sep-
arate key). Examples of keyed hash algorithms are HMAC-SHA1-DES3, and RSA-MD5-DES. The ``plain'' hash functions MD5, and SHA1 are not keyed.
krb5_crypto_get_checksum_type() returns the checksum type that will be used when creating a checksum for the given crypto context. This
function is useful in combination with krb5_checksumsize() when you want to know the size a checksum will use when you create it.
krb5_cksumtype_valid() returns 0 or an error if the checksumtype is implemented and not currently disabled in this kerberos library.
krb5_checksumsize() returns the size of the outdata of checksum function.
krb5_copy_checksum() returns a copy of the checksum krb5_free_checksum() should use used to free the new checksum.
krb5_free_checksum() free the checksum and the content of the checksum.
krb5_free_checksum_contents() frees the content of checksum in cksum.
krb5_hmac() calculates the HMAC over data (with length len) using the keyusage usage and keyblock key. Note that keyusage is not always used
in checksums.
krb5_checksum_disable globally disables the checksum type.
