I have an automated setup (debian) which includes a startup script that rsyncs to a server (always the same server). Everything works well - just that I have to manually confirm that the host is supposed to be added to the known_hosts
Code:
The authenticity of host 'myserver.com (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is 9b:ee:a6:47:hb:92:ac:76:81:94:18:7d:ad:8c:3e:25.

I start/stop lots of new instances as I'm learning to use Amazon EC2. Every temporary instance is added to the known_hosts file. Is this ever a problem for others who use EC2 a lot?
I'd like to tell ssh to skip this step anytime I connect to amazonaws.com. Is there a way to do that in the config? I'm using Linux & openssh.
Many of mails sent from my mail server that are in Queue;The main reason is deffered by domains like yahoo,aol,etc.but there is one more error that i keep getting and that is Host Unknown,Below is an example from mail log,The catch is,test mail sent on the same email id sent from my personal mail from the same server i.e. url was deliveredHowever,another mail containing client information sent from customercare@mycompanysdomain ended up in queue.
There are more examples of the same,around 20 domain have the same problem.

I've trying to add a route to a host to force traffic out of a clustered IP address...
IE I have a cluster and the IP address moves from host to host on failure of a resource. The IP address is just a simple alias of an interface so for example... bond0:0 192.168.1.1 and bond0 192.168.1.10
What I want to do is force a program that starts up on the cluster hosts which sends packets out to a listening server to only send out of the cluster ip address.
I did a route add -host 172.22.2.2 gw 192.168.1.1. But this doesn't seem to work if i try to send a ping the packets still go out the wrong address, and more and above that for some reason the ping doesn't work at all. If i remove the route the ping will work again.

want to use bootchart to see how much time its taking for things to load up and the desktop to settle. I am having a little trouble figuring out how to make sure that bootchard loads up each time (non-interactively) so I can easily put up the results and see what could be done better. The man page of bootchartd says :-"bootchartd is commonly used to profile the boot process for the purpose of speeding it up. In this case, it is started by the kernel as the init process. This is configured by adding the init=/sbin/bootchartd option to the kernel command line -- either interactively or by editing the bootloader's configuration file. Please refer to the documentation of your bootloader for details (e.g. lilo, grub or yaboot)."

I was wondering if it's possible to move the known_hosts file from ~/.ssh/known_hosts to ~/somewhere/.ssh/known_hosts . I have a server running Plesk and the user home directories do not have write permissions (they do have write permissions within the subfolders, however).
I was able to move the authorized_keys file by editing sshd_config AuthorizedKeysFile , but when I try to log in without password, I'm still prompted every time if I want to add the host to list of known hosts, and it fails to save every time since it cannot write to known_hosts. Thus I am still unable to automate some processes. I'd like known_hosts to be located in the same location as my authorized_keys, which does have correct permissions for users.
Currently I am populating a global ssh_known_hosts file with RSA and DSS host keys.
Code:
short_name, fqdn, 192.168.x.y ssh-dss.........
short_name, fqdn, 192.168.x.y ssh-rsa.........

Bit of an odd one, this. I've migrated a website from my old server to a new machine. Both servers run Ubuntu + Apache2. Both only serve a single site, apart from the default site.I've flipped the domain name to the new IP address.The trouble is that after moving the virtual host config over into sites-available, with the necessary link in sites-enabled, Apache attempts to serve from the default web root (/var/www) rather than the actual site content (in /var/www/technology). So for example, an attempt to browse.
View 1 Replies View RelatedI had a populated known_hosts file. I was editing it and for a split second I saw a permission error when I saved it. I went to check what the error was and the known_hosts file was blank.

Sounds good... but when I look at my known_hosts file, it is blank. I check the permissions and it is owned by my account. .ssh/ permissions are correct too.
I deleted known_hosts and then tried connecting again, and it creates a file but it stays blank. No host keys get added.
It just started happening after I saw that permission error.
root user's known_hosts file updates fine though.

I'm trying to rsync files and directories from a RedHat linux host(v 4.5 & 4.7) to a Windows server 2003R2 Standard Edition with cygwin running. I'm executing the rsync command from the cygwin shell. The transfer involves rsync'ing approximately 1 TB of data from the linux server to the windows server. After about 280+GB of data transfer, the transfer just dies.
There seems to be no particular file or directory that the transfer stops at. I'm able to rsync GB's of data from other linux hosts to this cygwin server with no problem. Files and directories rsync fine.The network infrastructure is essentially the same regardless of the server being rsync'ed in that it is GB Ethernet running through Cisco GB switches. There appear to be no glitches or hiccups across the network path.
I've asked the folks at rsync.samba.org if they know of any problems or issues. Their response has been neutral in that if the version of rsync that cygwin has ported is within standards then there is no rsync reason this problem should happen.I've asked the cygwin support site if they know of any issues and they have yet to reply. So, my question is whether the version of rsync that is ported to cygwin is standard. If so, is there any reason cygwin & rsync keep failing like this?
I've asked the local rsync on linux guru's and they can't see any reason this should fail from a linux perspective. Apparently I am our company cygwin knowledge base by default.
Just something that struck me while working on our virtual servers today.
I have bonded 3 NICs at the host in Ubuntu Server 8.04 LTS. They are using mode 0 for Round-robin. Point is to increase the speed/performance of all the servers, but mainly the fileserver. The fileserver is a virtual server running Ubuntu Server 8.04 LTS on VMware Server 2.0.
1) I noticed the NIC in the slave OS reported link speed as 1000 and Im unable to change it as the NIC (virtual one) doesnt support it. Does this not really matter, as the NIC doesnt exist, and it will run at higher speeds anyway? Or do I have to remove the bond on the host, bridge all 3 interfaces from the host to the slave OS, and then make a bond in the slave OS?
2) While at it, does mode 0 only increase performance on data being sent from the host or does it also increase the available incoming bandwidth?

Has anyone had any experience on using SUA(Services for UNIX Applications) rsync to "pull" files down to the Win2k3R2 server from a linux rsync host?I was trying to use cygwin rsync before until I found out from cygwin that the cygwin port of rsync was "flakey" and would fail intermittently for no apparent reason. cygwin suggested I use SUA or SFU for rsync services.
I've looked for/ am looking for any experience using SUA rsync to copy files down from a linux rsync host to the Windows host via rsync on the Windows host. Also, if you have done this successfully, do you have any pointers/caveats you can share on how you got it working? What I am basically looking to do is copy files and subdirectories of files from a linux host using rsync to some static location on a Windows server on a scheduled basis so that I can backup the windows server to tape using Symantec's Backup Exec application.
I'm doing it this way to avoid deploying the Remote Agents for either linux or Windows on the target hosts. As an alternative I've seen reference to a product called DeltaCopy that uses a native Windows rsync port with the native linux port of rsync to do what I need also.I realize this is not a strictly linux question, but more of a hybrid as I'm moving data to and from Windows and linux hosts. So, if this is too Windows-y a question, please say so and I'll withdraw my question.

Afternoon all, we have an older box which hosts all our corporate mail, but he's a bit old, small hard drive, etc. We have a new app which sends a lot of mail and 2 weekends in a row has killed the box.So I want to play a bit with postfix, and have it installed and ready. The main question is can I have him 'send' all the mail out but keep the incoming since it's not much going to the primary? Naturally it's yes, but what do I need to look at record wise?I know there are new things like spf, spoofing, etc and when someone get's that message from admin@domain.com, there servers naturally reverse lookup, but he won't be the box that receives for that domain so will it simply not accept?
View 3 Replies View RelatedThis probably sounds like a stupid question, but I need to add a NIC to an existing server running Ubuntu Server edition 8.10. My question is what changes I need to make once the NIC is physically installed? I guess it will not be autoconfigured, so I will have to add it to the /etc/network/interfaces manually, which is ok as I need to set it up with a static interface anyway.Is there a good How-to or set of instructions on how to do this?

I'm an experienced PC technician running a slackware 13.1 distro on a server at home. I've currently got 2x 1TB drives in the box allocated as raid1 for the OS and everything I want to run on the machine. I'd like to think my question/needs are fairly straight forward, I am buying 2x 2TB drives to add to this machine as it serves as a NAS box for one of its roles. I'd like these in raid0 as the data that would be going on it is not that important to me. The question is, after adding the new drives to the system, once I boot up, what do I need to do to the system to get the drives added and working sucessfully as a single raid0 volume that I can then samba share out to my network. To clarify, I understand a little of mdadm as I've used it to raid1 my existing setup when I installed, and I'm fine with the samba bit after.

I currently have a home server, running Gentoo, with IPv4 connectivity through Qwest.I feel that it is important that this server also be available through IPv6 (I'm aware that, after exhaustion, my end still might not get an address through DHCP).I currently use dyndns.org to provide me with a DNS entry mapping jrvanwhy.homelinux.net to my IPv4 address.I do not have any sort of tunnel set up yet for IPv6 traffic yet. The new domain name does not necessarily have to be the same [URL].I do not wish to spend any money on this.Is there some free service I can register for that would do both the tunneling and the DNS entry? Is there a service that can supply me with an IPv6 DNS entry, if I get a static IPv6 address with another tunnel broker, like Hurricane Electric?
