Sep 19, 2010ENV: openssh-server-5.4p1-1.fc13.i686 Problem: I am unable to ssh using Putty (when using ssh-auth/pki) to a fedora box . I get the message: Server refused our key. Here's what I tried so far:
- Tried generating rsa (as well as dsa) keys on the linux server and put the generated public key in the ~/.ssh/authorized_keys. Then I converted the private key using PuttyGen.
- Also, tried generating keys using PuttyGen and then converted the public key and placed it on the server
- Configured the sshd server (ssh_config) for using RSAAuthentication=yes. Tried all combinations and purmutations; however, I still get the "Server refused our key" error.

Sep 24, 2010I have the opportunity to set up our local public library with a linux server. The primary need is for the server to land wifi users to a hotspot splash screen where they will accept terms of use and indicate what town they are from by checking a box or selecting from a dropdown menu. Users of terminals in the library would also have to indicate what town they are from. Things such as content filtering may come later. What distro would be recommended for this? Ease of use and configuration is important. They basically want to track use of the internet.

Server :: SSH: Automated Login Via Public Key Not Working?
Aug 17, 2009Run a script on ServerA which uses a ssh-connection to ServerB to execute a few commands on ServerB. As ServerB only allows login with username+password the whole stuff gets more complex. SSH provides key authentication enabling passwordless login as you probably know. So as stated in many tutorials I did the following:
Quote:
ssh-keygen -t dsa
ssh-copy-id .ssh/id_dsa.pub osr@10.17.120.207
Trying to connect with
ssh osr@10.17.120.207
should now be passwordless but I'm somehow still getting the prompt for the password.here the output from ssh -vvv osr@10.17.120.207
Quote:
OpenSSH_4.1p1, OpenSSL 0.9.7d 17 Mar 2004
debug1: Reading configuration data /etc/ssh/ssh_config

interesting are probably the following lines:
Quote:
debug3: Not a RSA1 key file /users/osr/.ssh/id_dsa.
debug2: key_type_from_name: unknown key type '-----BEGIN'
Software :: Logging Into Server Using Public Keys?
Mar 12, 2011I've got a slight issue with logging into my server using public keys.
It was working fine, until I had to rebuild my desktop machine. I had the key copied to the server, and passwordless logins where fine.
However now I have rebuilt my desktop, I cant get to the login.
So heres whats happend.
Rebuilt id_rsa.pub, server will not allow login. Remove id_rsa.pub and the server allows password based login.
On the server, removed authorized_keys and known_hosts. makes no difference. Server still disallows keyfile, but will allow password when id_rsa is not present on the client.
Heres a -v of the login chat with keyfile
Code:
michael@eve:~$ ssh -v server
OpenSSH_5.5p1 Debian-6, OpenSSL 0.9.8o 01 Jun 2010
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to server [ser.ver.ip] port 22.

So, is there anyway of getting the server to forget the previous keys, it is remembering, As previousily said, I have completly removed the contents of ~/.ssh/ on both the clients and the server.

View 1 Replies View RelatedUbuntu Networking :: Public IP Vs Private IP For DHCP Server?
Feb 12, 2011My 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?
Networking :: Cannot Access Public Web And Mail Server From LAN Addresses
Aug 5, 2009I have two nagging problems on one network which I do not have on another elsewhere, both using uptodate Debian servers. The server is on the private subnet behind a router/adsl modem. The symptoms of the one which does not work
1) Users cannot access their web site from lan. If they try, they get to the router web interface, same as if they entered http:10.0.0.138 which is the router's lan address.
2) Users cannot access smtp or pop3 service using the domain name, they can access it only using the servers LAN address.
I fear that I might have not set up the router properly because appart from that the two servers are almost identical but I do not know where I might have made an error.

View 1 Replies View RelatedFedora :: NFS Access Denied By Server While Mounting Nfsserver:/public
Dec 3, 2009Since FC6, NFS became very finicky and seemingly causes servers to randomly denying mounts from some terminals but not others, with all exactly the same new FC installation and exactly the same hardware - crazy!. The only difference is hostnames of the terminals trying to mount NFS volumes on the server and I made sure that /etc/hosts on all terminals and servers contain each others ip addresses and hostnames. I always uninstall SELinux which is truly a huge pain in a corporate environment. Is there ANY way I can relax the NFS authentication on the server in order to make sure clients can mount volumes?
e.g. the following is encountered often, with sometimes crazy situations that clients can only mount nfs volum es from the server after I first boot the server and then ALL the terminals. It is painful as you might agree! Other way round, no go, client will not mount until server is booted and then client booted.
In this case I really prefer windows lackey security. It works. Never mind how crappy windows is, at least I don't have diabolical access problems on servers.. NFS used to be very nice about 6 years ago but truly sucks recently imo. /]# mount -o soft -t nfs nfsserver:/public /xfer mount.nfs: access denied by server while mounting nfsserver:/public
Ubuntu Security :: Nautilus: Connect To Server Using Public Keys

However, I changed the server to only accept Public Key Authentication and disabled password authentication, and as a consequence I could not login using Nautilus anymore. Is there some way to make this work?

Networking :: Using A Public-Facing SSH Server To Broker A Connection Between Two Clients?
Feb 22, 2010I'm sure this is possible... I'm just not sure how. Yet! I have three machines. One is at home behind my firewall and has a dynamic IP. That's fine as I don't really want to open any ports on my home firewall. The second is at work sitting behind the firewall there- and I'm not even going to ask for approval to NAT an IP to my PC at work :-).
The third is in a data center far away. I only have a shell account on this server but other than that shell account not being root, I can do most anything I like with that account. What I would like to do is SSH to this server simultaneously from my home and work PCs and, via this third machine, make them talk.
This is pure geekery so it doesn't matter what they say to each other; I just want to make them talk. Maybe one uploads a file and the other just pulls down that file. Maybe one opens a FIFO on the remote server and starts writing to it while the other starts snarfing that data. In fact, I like this latter idea best, I think. How would you do it? What scripts (fired by cron if need be since I'm ostensibly away from at least one of the PCs at any given time) would you use?
Server :: Samba Config - Can't Get The Public Read-write Dir To Work

Networking :: Setting Up A VPN For Windows Clients To Reach Debian Server Over The Public Internet
Jan 30, 2010I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet.

However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.
View 1 Replies View RelatedSecurity :: Secure And Automated Backups - Add Public Key To Authorized_hosts File On Prod Server?
Mar 13, 2010I'm trying to find a secure way to backup files on my Prod Server to Backup Server. It must be automated, so I will need to run a command with cron which will login to Prod Server from Backup Server and backup data. 1. Do you think it would be secure enough to do this by creating an passwordless RSA private key on Backup Server and adding it's public key to authorized_hosts file on Prod Server? I can't think of a way to Automate this without having to enter any passwords without passwordless RSA key. Is there another. more secure way? 2. Should I create a special user for backup, which will only have read access to all files in the directory that I am backing up? If so, How can I run a check that this new backup user indeed has read access to ALL files in the folder that I intent to back up? How can I ensure the backup process will not skip files due to some permission problem? 3. I'm thinking of using rsnapshot tool, which uses rsync.

Oct 28, 2010host is windows 2003 server 64-bit
guest is ubuntu 9.04 server 64bit
Qemu : 0.11.1
Qemu manager: 7.0
from Qemu manager, if network card is using User Networking, it's a NAT and I can see that Guest Ubuntu has an ip address 10.0.2.15 and is able to access the internet. However, as Guest ubuntu is running server so I want to do use Tap networking and I assue with Tap, the Guest ubuntu will get an ip address which is in the same subnet as host machine by dhcp. so from Qemu Manager 7.0, I changed Network card to be:
NE2000PCI
Vlan Number =0
VLAN Type: Tap Networking
Mac address: tap0's mac address from host
TAP Network Adpator: Tap0
Note that tap0 was created by openvpn. and then fired Ubuntu guest, ifconfig shows no ip address on eth0 (which has the same mac address as Tap0) so the guest Ubuntu has no ip address and can't access public.
Ubuntu Servers :: Setup Access Properly From A Public Address To A Monitoring Server That Works Fine Locally?

Everything works from public access until I try to link to a CVS repository. The rancid CVS repository is set up as a separate server (virtualhost).

Dec 18, 2009Ok let's say I have Apache Webservers on 2 different machines within my network, I have http://outterABC.com setup at dyndns.org to point to my modem at home, and my router forwards Port 80 to the ServerA Machine (i.e. 192.168.0.3). I can access my webpage I setup for the Server A Machine.
But what I want to try and do is somehow access my ServerB machine's website that is on my same network. I tried something like this http://ServerB.outterABC.com and the apache page came up with something like the page wasn't available. I want to access the content of the ServerB website, but because I have only one router, i can only forward Port 80 site traffic to my ServerA machine's website. I'm sure it's a different syntax I should use but i'm just not sure what I should enter to bring up the apache root web page for the Server B website via http://outterABC.com
I tried setting up DNS A records on ServerA, but I don't think it will work with what i'm trying to do above.
Server :: Server Configuration For Small Office Server, Which Smtp, Pop Imap Server And Backup?
Apr 2, 2010I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
