Hi, i'm just starting out with OpenSSL. I've worked up a little example to generate a RSA key pair and save it into both private and public PEM files. All seems ok, but then i'm try to use it with actual openssl and get the following error: Code:

ssh: is there any issue with adding my personal public key to authorizedkeys?

location: linuxquestions.com - date: October 6, 2008
Is there anything fundamentally wrong with using my own public key for logging into my system? That is, appending ~/.ssh/id_rsa.pub or ~/.ssh/id_dsa.pub to ~/.ssh/authorized_keys

OpenSSL private, public key and certificate, what exactly do i send to client?

location: linuxexchange.com - date: August 4, 2014
I am starting out with SSL. I have created server and client applications accord to this and this example. Searched the internet for some information about the keys and certificates. Found this command openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mycert.pem -out mycert.pem which i used for both, the server and client sides and it seems to work. I opened the cert.pem file to find out, that this file contains both, private key and certificate data. I think giving out private key is a bad thing, so there must be something wrong with what i did. AND i didnt see a public key in there. Then i found this short guide on how to create private key. All good (i refused to use the version which asks password). Now i see the file contains only private key. NEXT I find this short guide on certificates. Following step 4 i created a certificate using the previously generated private key. Checked the file, confirmed there was only certificate data in it. Great. I started thinking,

Punkbuster CD key issue with Enemy Territory

Hello I've installed Enemy Territory without any grief, and the game runs fine (if a little jerkily at times - my system specs are not quite what I'd like).

Perhaps someone on the forum has a solution? Thanks

SSH key issue

location: linuxquestions.com - date: July 29, 2008
Hi, I am trying to setup ssh keys so that I do not need passwds to scp/ssh between systems. System nona-man is running CentOS4.5 and node1003 is running CentOS5.1. I generate the keys for nona-man: ssh-keygen -t rsa no passphrase. Then via kickstart copy nona-man's id_rsa, id_rsa.pub and authorized_keys (copy of id_rsa.pub) files to node1003:/root/.ssh. All root/.ssh dir/files have the permission 700/600, respectively. I can ssh as root into the node1003 from nona-man without a passwd ,but not the reverse. My /etc/sshd_config file is a default and unchanged. /etc/hosts.allow on nona-man allows ssh from the node1003. host.deny is ALL:ALL nona-man:/var/log/messages shows nona sshd[2111]: ROOT LOGIN REFUSED FROM ::ffff:172.20.101.3 (node IP) I do not want to allow root logins, as other nics are exposed to the outside world. Below is the debug info from the node to nona-man. One debug message seems strange to me: It is looking for rsa1 key... debug1: identi
