Hi All,
I need to scp a folder from one host to another in a script. When I run a command , it asks me to authenticate for the RSA key fingerprint for the first time.
# scp -r temp1 root@iqcarrot:/root/
The authenticity of host 'iqmango.apac.avaya.com (148.147.172.112)' can't be... (2 Replies)
I am trying to SFTP to a couple sites. One has an RSA-KEY that was sent to me. Currently I am running that manually using WinSCP. I would like to set it up as a CRON process on our Linux host (Sun).
Can I use the rsa-key they sent me in any directory or does it need to be placed in a specific... (2 Replies)
Dear All,
I need to decrypt with private key most of the time and this works for RSA. At times I need to decrypt with public key (data is encrypted with private key). This does not seem to work via VB.Net. Is there support for such an activity in Java on Linux or Windows ? Please advise.

I want to automate the process of generating RSA keys. I want to remotley login to a linux machine from a windows maching without having to enter a password. For this I need to generate the RSA key pair. but I want to do this procedure on alot of linux machines. For which I was looking to automate... (2 Replies)
Hi there,
I have a Linux Debian machine with the following fingerprint :
e1:95:11:46:ff:d1:e3:4a:a3:34:1a:25:b4:d8:f1:cb.
I'd like to set this fingerprint to :
cd:19:bd:f6:8e:00:7a:69:14:52:a1:73:cb:15:a5:ca.
I have very specific reasons to do that. So please only answer if you know how... (5 Replies)
Guys
How do i add RSA key for a host ?
I was able to connect to a host some time back but now its not connectable ,via SSH.
Message i get is :

I'm stumped on an issue I'm having with RSA key based SSH logons.
I have 30 servers in a database cluster. They are all Red Hat Enterprise Linux Server release 6.4.
I want to be able to run a command on all of them from any one of them using SSH.

Hi All,
I have a scenario where from machine1 I need to establish sftp/ssh to machine2.
Internet is full of examples of this how to generate they key-pair etc... but all examples assume that the account is the same on machine1 and machine2.
I would like to do the following:

Hi All,
I have a requirement where i need to check if an rsa public key corresponds to a private key and hence return success or failure. Currently i am using the command
diff <( ssh-keygen -y -e -f "$PRIVKEY" ) <( ssh-keygen -y -e -f "$PUBLICKEY" )
and its solving my purpose. This is in... (1 Reply)

moduli
MODULI(5) BSD File Formats Manual MODULI(5)NAME
moduli -- Diffie-Hellman moduli
DESCRIPTION
The /etc/ssh/moduli file contains prime numbers and generators for use by sshd(8) in the Diffie-Hellman Group Exchange key exchange method.
New moduli may be generated with ssh-keygen(1) using a two-step process. An initial candidate generation pass, using ssh-keygen -G, calcu-
lates numbers that are likely to be useful. A second primality testing pass, using ssh-keygen -T, provides a high degree of assurance that
the numbers are prime and are safe for use in Diffie-Hellman operations by sshd(8). This moduli format is used as the output from each pass.
The file consists of newline-separated records, one per modulus, containing seven space-separated fields. These fields are as follows:
timestamp The time that the modulus was last processed as YYYYMMDDHHMMSS.
type Decimal number specifying the internal structure of the prime modulus. Supported types are:
0 Unknown, not tested.
2 "Safe" prime; (p-1)/2 is also prime.
4 Sophie Germain; 2p+1 is also prime.
Moduli candidates initially produced by ssh-keygen(1) are Sophie Germain primes (type 4). Further primality testing with
ssh-keygen(1) produces safe prime moduli (type 2) that are ready for use in sshd(8). Other types are not used by OpenSSH.
tests Decimal number indicating the type of primality tests that the number has been subjected to represented as a bitmask of
the following values:
0x00 Not tested.
0x01 Composite number - not prime.
0x02 Sieve of Eratosthenes.
0x04 Probabilistic Miller-Rabin primality tests.
The ssh-keygen(1) moduli candidate generation uses the Sieve of Eratosthenes (flag 0x02). Subsequent ssh-keygen(1) pri-
mality tests are Miller-Rabin tests (flag 0x04).
trials Decimal number indicating the number of primality trials that have been performed on the modulus.
size Decimal number indicating the size of the prime in bits.
generator The recommended generator for use with this modulus (hexadecimal).
modulus The modulus itself in hexadecimal.
When performing Diffie-Hellman Group Exchange, sshd(8) first estimates the size of the modulus required to produce enough Diffie-Hellman out-
put to sufficiently key the selected symmetric cipher. sshd(8) then randomly selects a modulus from /etc/ssh/moduli that best meets the size
requirement.
