Programming :: Sending RSA Public/private Keys Into Calling Function?

Sep 9, 2010

Programming :: C++ Using Private Variable In Public Function?

Feb 6, 2011

I have a class in which a have declared a private variable "time". In one of the public functions, I am returning the value of "time" (either directly by using "return time;" or by something similar to "x=time; return x;" but I keep getting a compiling error saying that "time" is not declared in this scope.

Ubuntu :: Use Openssl Public And Private Keys So Only A Host With The Public Key Could Access / Decrypt The Filesharing

Aug 2, 2011

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

I'm trying to set up my laptop to ssh into my home server, but I'm trying to find how to generate the public/private keys. I was able to do it in Slack 12.2 by just running ssh-keygen, but that command is not in 13.x.

OpenSUSE Network :: 11.3 - SSH Connections Using Public / Private Keys Rejected

Aug 10, 2010

My ISP has for a long time had a broken forward/reverese DNS so that my ADSL connection with static IP address resolves to a completely different IP address on a reverse query. This has not been a problem until I upgraded a remote server from 10.3 to 11.3 last weekend and now ssh connections from my ADSL connection to it using public/private keys are being rejected with the following message in /var/log/messages (IP addresses changed):
Aug 10 12:00:32 penguin1 sshd[1270]: Address maps to, but this does not map back to the address - Possible Break in Attempt!

But if I log in interactively with username & password, the connection succeeds. I've changed the StrictModes setting in sshd_config to 'no' but this hasn't resolved the problem. Obviously something in 11.3 is being stricter about this IP mismatch than it was in 10.2 (and no, the server is not using a firewall). There must be something I can change to make sshd more permissive? I've tried before to get my ISP to fix their problem but no luck. This needs to be sorted as a server at my home (which does not run SuSE) retrieves backups from the remote OpenSuSE 11.3 server every night using scp and these are now failing.

Ubuntu Servers :: Setup The Necessary Public/private Keys To Use In FileZilla?

Jan 26, 2010

I installed OpenSSH via tasksel and am using Webmin for administration. I'd like to be able to SSH externally and want to setup the necessary public/private keys to use in FileZilla. In Webmin, under Servers > SSH Server I can click 'Host Keys' and see an RSA key. Is this the public or private key for my server? Do I need to copy this into a text file to import it into FileZilla on my remote PC (that I want to connect from)? Is that all that needs to be done (aside from opening the port on my router/firewall)? Or, is there an automated way to set this up via Webmin?

Ubuntu Security :: Public / Private Keys On Multiple Servers?

At the moment we have one SSH server with the private key being on a usb flash drive, and the public key being on the server in authorized_keys2. Now that three more servers are coming online, should we generate new keys, so we have muliple private and public keys (one pair for each server), or use the same two keys to access all the servers

General :: Github Private/public SSH Key Authentication?

Jan 28, 2011

I created a private/public pair. I put the public on github.But I can never push to github.Every time, it says public denied. In order to push, I need to do this:eval ssh-agentssh-add ~/.ssh/github_dsaThis is driving me nuts that I have to do this every time. So, I just put it in my ~/.bashrc file. I feel like that's a hack. Is this normal?

Networking :: SSH Setup - Public / Private Key Authentication?

May 7, 2010

After years with Linux and using ssh on a daily basis I have to admit I've never setup public/private key authentication and I've never run passwordless logon to ssh. It's not that I've never tried, I have - I've just never got it working. That to me is an almost alien concept as I am a tinkerer at heart and rarely stop until something is working the way I'd like it to. I get the principle of what's going on but I've always had a mental block about it.

Red Hat :: Public And Private NIC - Hardening Snmp Via IP Tables?

Dec 7, 2010

Most of our machines have public facing and backend mgmt private nics(ie: 192 or 172 networks). I wrote a rule that matches source ip(our monitor on a 192 network) on udp 161 accept. I want to prevent listening on that port on the public. Is the source rule sufficient or should I match the interface and then source? I know there a many ways to do this. I need to verify from the public network with a port scanner?

Ubuntu Networking :: Public IP Vs Private IP For DHCP Server?

Feb 12, 2011

My Ubuntu server is now providing routing duties to my network, but I'm having trouble opening ports to my network. I have a DynDNS account, so the IP is always current, but I can't ping even my IP directly.

My network map looks like

Internet > SpeedTouch DSL modem with DHCP > eth1 > Ubuntu > eth0 > LAN

With the modem providing a 192.168.1.xx IP to eth1, I can browse fine. The default gateway is my modem. I switched to the public IP of the modem so I could use iptables for firewall duties, but I was locked out of the internet. No gateway was set when I did that, but eth1 received the public IP of my modem.

How can I use the public IP assigned to eth1?

General :: Configure Ssh To Stop Requiring Public/private Key Auth?

I configured ssh on one of my servers to require public/private key authentication and deny access to login requests not using a public/private key. Now I need to unconfigure that,but I can't remember how I did it. I've looked through ssh_config and sshd_config, and nothing rings a bell. Googling only tells me how to enable public/private key authentication, not how to require it or stop requiring it.
