automatic SFTP without doing passwordless key with ssh-keygen
I need to automate a file transfer thru SFTP. But I cannot do a passwordless key with ssh-keygen between the servers. Is there any other way like we do something like below in FTP???
Code:
ftp -n hostIP << EOF
user userid password
get filename
EOF
Hi, When Iam trying to do SFTP it is asking for password everytime. Can I have any alternative where I can provide the password in script itself. Because there are some control-M jobs which runs without user interaction. So please let me know the script where we can provide the password in the... (2 Replies)
Hi,
I have two Unix servers A and B. I have a script in server A. I want to connect to server B from A using ssh only and without giving passwords everytime i connect. I went through other posts regarding this and I generated a public key in server A and copied that in server B. Now when I... (3 Replies)
Hi,
please guide me create a public/private key using ssh-keygen, lets say I have been access to server named pngpcdb1with a userid and password ...!!! and also please explain in detail the concept of these keys and ssh as I was planning to use them in ftp related scripts..! Thanks in... (1 Reply)
Hi,
I am new to unix, recently i was exploring password less remote connection to the ftp server and in that I was exploring the ssh-keygen utility, that it generates private & public keys that helps in transmitting files in encrypted format.Could you please explain me in detail about the... (1 Reply)
Hi,
I was going thruough the password less authentication of keygen-ssh that will help us in generating keys...One thing that is not clear to me that if in nearby future we conncet to remote ftp server in that case now we need to only provide the user id itself that is password would not be...

Hi,
I using ssh-keygen for passwordless authenciation firstly
and I am following these steps mentioned below...
1) Login to pngpcdb1 using your user/pass
2) type 'bash' (without quotes)
3) ssh-keygen #generates private and public key.
4) copy this private key to the location of your sftp... (1 Reply)

Hi,
i have done the keygen-ssh settings but rite now I log through putty I enter my credentials and then when i successfully log in, then I issue the command ssh server name then I again enter into the server but... (1 Reply)
Hello,
Need a suggestion to setup private key passwordless authentication. I am not sure this can done or not :wall:
here is the sincerio
I have two servers, sever1 with a user "user1" and servera with usera
here dataflow: usera from servera, will pull/push files to server1 on user1... (2 Replies)
Hi guys,
Anyone encountered the following error.
1.) all keys and passphrases worked on aix 7.1.2
2.) upgraded to aix 7.1.3sp5
3.) none of the keys / passphrases work anymore.
4.) when generating new keys without passphrase everything is ok.
5.) when generating keys with passphrase and... (16 Replies)
For some reason, when I try copying my public key to the server, despite it showing as being successful:
rob@linux044:~$ ssh-copy-id -i /home/rob/Work/Keys/keys.txt.pub !@#$%.com
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/rob/Work/Keys/keys.txt.pub"... (7 Replies)

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.
