Hi,
I am using a remote storage service for backing up our data - we want to have a script run as part of a cron job which would do the backups from our local Linux machine to the service's Linux machine.
I want to use tar and ssh to do this (rather than mounting the disk and using cp) .... (5 Replies)
Hi all,
Basic Requirement:
To SFTP large files (usually 10GB). We use webMethods 6.1.2 (installed on Unix) as the orchstrator and make underlying Unix system calls to do the processing.
That is, if we have to SFTP a large file - webMethods will invoke a Perl script on the underlying Unix... (2 Replies)

Hi,
I have set up my remote server for password-less login via ssh. If I run the command on my server - ssh user@remoteserver "ls -l"
I get an output, but when I try to do this via java

I'm a sysadmin trying to help out one of our DBA's setup the RMAN backups (Oracle 11g on rhel5 ) so they can schedule and control them from the OEM grid control.

We have RSA SecureID softtoken key generator on my Windows machine.
It generates new keys every 1 minute.
Any HPUX server (be it ServerD or ServerP) requires my ID and the randomly generated RSA SecureID softtoken key from my Windows to login.
I login to ServerD.
Then I run a script... (0 Replies)

Hi,
When i am trying to connect to other server using ssh coomand, it is prompting for password.
But i want to hardcode it with username so that it should not prompt for password.
And i dont want to use "ssh-keygen" method as it is not allowed.
Please help me.

rsa_private_encrypt
RSA_private_encrypt(3) OpenSSL RSA_private_encrypt(3)NAME
RSA_private_encrypt, RSA_public_decrypt - low level signature operations
SYNOPSIS
#include <openssl/rsa.h>
int RSA_private_encrypt(int flen, unsigned char *from,
unsigned char *to, RSA *rsa, int padding);
int RSA_public_decrypt(int flen, unsigned char *from,
unsigned char *to, RSA *rsa, int padding);
DESCRIPTION
These functions handle RSA signatures at a low level.
RSA_private_encrypt() signs the flen bytes at from (usually a message digest with an algorithm identifier) using the private key rsa and
stores the signature in to. to must point to RSA_size(rsa) bytes of memory.
padding denotes one of the following modes:
RSA_PKCS1_PADDING
PKCS #1 v1.5 padding. This function does not handle the algorithmIdentifier specified in PKCS #1. When generating or verifying PKCS #1
signatures, RSA_sign(3) and RSA_verify(3) should be used.
RSA_NO_PADDING
Raw RSA signature. This mode should only be used to implement cryptographically sound padding modes in the application code. Signing
user data directly with RSA is insecure.
RSA_public_decrypt() recovers the message digest from the flen bytes long signature at from using the signer's public key rsa. to must
point to a memory section large enough to hold the message digest (which is smaller than RSA_size(rsa) - 11). padding is the padding mode
that was used to sign the data.
RETURN VALUES
RSA_private_encrypt() returns the size of the signature (i.e., RSA_size(rsa)). RSA_public_decrypt() returns the size of the recovered
message digest.
On error, -1 is returned; the error codes can be obtained by ERR_get_error(3).
SEE ALSO ERR_get_error(3), rsa(3), RSA_sign(3), RSA_verify(3)HISTORY
The padding argument was added in SSLeay 0.8. RSA_NO_PADDING is available since SSLeay 0.9.0.
