Generating Private Key On Server To Download And Access From Any Machine

hi people,

i reinstalled my server with centos 7 to get familiar with it...

i have a laptop that im using cygwin on to ssh into the centos 7 server.

i ran ssh-keygen -t rsa on the server and now in .ssh i have a public and private key created.

i copied the public key from the server to my C:\cygwin64\home\Administrator\.ssh\known_hosts file

now when i input:
ssh userontheserver@serversip

it asks for the passphrase which i created when i did the keygen
on the server

when i put the passphrase in it says permission denied
and returns me to the command line

what am i doing wrong?

do i have the steps correct?

am i right in saying that you need to have the servers public key in your known_hosts file on the client computer to get communication working?

Using a Raspberry Pi w/ Debian

Read the manual and several "how-to"s and am getting nowhere

vsftp is running and making a log file. I can get to the Pi with putty or SAMBA

Ultimately want to be able to both(I) ftp in under the "pi" user to access files remotely and (II) have people sending me huge files ftp them in anonymously

Have tried (I) the ftp client in Windows 7 Internet explorer 11, (ii) the ftp client in the Windows 7 "map network drive" UI, and (iii) ES file explorer on my Android phone.

The android phone tells me there is no server there. Windows 7 gets no password challenge, gives no error indication, but does nothing useful. The vsftpd log file shows some attempt by the Windows machine, nothing for the Android.

Config file and log file attached.

The Android is trying to use port 21, the config file mentions something about port 20. Which ports do I need to forward in my router to enable remote access?

Any help appreciated.

Thanks. Jonathan

hi guys,

i understand the concept of a public and private key for ssh signing and encryption...i just dont get the implementation.

if you have a client and a server and you want two way communication do both have to have each others public keys in the .ssh/authorized_keys files on each respectively?

should you use a password? does it matter if you want to run say rsync from one to the other with a cron job or script?

does anybody just have a breakdown of exactly what you need to do and how it works in different situations...

i found this:

https://www.digitalocean.com/communi...up-ssh-keys--2

seemed to help...but im still not 100% clear...

I have two centos 7 Server machines. "Machine-1" is having two NIC cards, one with public ip and another with private ip address. "Machine-2" is having a one NIC card with a private IP Address. how can i configure NAT on machine-1 to forward all TCP Traffic coming on public ip to the private ip of machine-2.

Pls give me a solve.its give me pain

[FONT="Times New Roman"][SIZE="3"]Hi All,
I have installed the Opsi-server in centos by following this http://download.uib.de/opsi_stable/d...ble-en.pdf.The opsi server was installed successfully and the server GUI is opening through browser from existing windows machine.But not able to add the Windows clients to the opsi server.How can i add the Windows machine to Opsi Server and How to map the opsi-depot server drive into my Windows machine.

I have been asked to setup an SFTP which uses RSA public key authentication.

AS it was already in use I have opted to use CygWin and I can get it to work with passwords fine.

we are going to be hosting the SFTP server with users from the clients office connecting to it. The client has sent me their public key.

Having done LOts of reading and even more attempting to configure the server I just cant get it to work. Most of thetime I get..
ebug1: Host '127.0.0.1' is known and matches the ECDSA host key.
debug1: Found key in /home/ColoniAdmin/.ssh/known_hosts:1
debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug1: SSH2_MSG_NEWKEYS received
debug1: Roaming not allowed by server
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Trying private key: /home/ColoniAdmin/.ssh/id_rsa
debug1: Trying private key: /home/ColoniAdmin/.ssh/id_dsa
debug1: Trying private key: /home/ColoniAdmin/.ssh/id_ecdsa
debug1: Trying private key: /home/ColoniAdmin/.ssh/id_ed25519
debug1: Next authentication method: keyboard-interactive
debug1: Authentications that can continue: publickey,keyboard-interactive
debug1: No more authentication methods to try.
Permission denied (publickey,keyboard-interactive).

I have once managed to get it to the point of asking for a passphrase for the private key but I don't have a private key (that I know of) just the public key the client sent us. and I certainly don't want to have to use passphrases

Their public key is in the authorized_key file on our server within the .ssh folder of their home folder. I have amended paswd and sshd_config to set home location and to allow RSA authentication.

All and any advice is super welcome, I have been doing this for 2 weeks now and i just wont work.

HELP HELP HELP!!!!!! ;-)
Thanks

I have installed phpmyadmin , when access http://192.1010.118.0/phpmyadmin ,it pops the error

Code:

Forbidden

You don't have permission to access /phpmyadmin on this server.

I check the phpmyadmin.conf , I have released "allow all" to all directory .

I also check the /var/log/httpd/error_log, it have the following error , I tried change all files permission to 777 but still not work , would advise what is wrong in my server ? thanks

Code:

[authz_co error] [pid 2525] [client 192.1010.118.0:51878] AH01630: client denied by server configuration: /usr/share/phpMyAdmin

I'm not sure if this should be in the newbie section, but I am somewhat of a newbie, so here goes:

In a home network, I have an Xubuntu file server with a Samba share that has me as the owner and authorizes me to access the share.

On another computer, I have Mint running and providing various services, including webdav on Apache with SSL. In the var/www/webdav directory of the Mint computer, I have the Xubuntu Samba share mounted. This is supposed to allow me to access the Samba share from the public internet.

Everything works fine except for one big problem: Apache requires the owner of the webdav directory to be user "www-data," and I can't figure out how to give www-data access to the Samba share, since www-data is not a user on the Xubuntu computer, and moreover I don't know the password for user www-data.

Can anyone figure out how to get around this problem? In particular, is there a way to configure the Samba share on the Xubuntu computer so that user www-data on the Mint computer can have access to it?

(Incidentally, I have my reasons for using two computers, one as a file server and one as a web server. Also, I am thinking about switching to NFS instead of Samba, but I'm not sure if even that would solve my problem.)

Hello Guys,

I am an newbie, just started with linux, I have installed centos 6.6 and learning it. But I got stuck in some user controls,

Can anybody Help ??

Once again thanks Again for reading, really appreciated

I set up public key authentication between my MacBook and and VPS for added security and convenience when I SFTP things to my VPS.

Now I have some new clients who want me to manage their websites, and I want a similar set up for each client.

Do I need a public/private key pair for each client?

How can I be sure that whatever I do in my SFTP client doesn't put the other accounts - particularly my own VPS - at risk?

Thanks,


Rob
