Re: [CentOS] CentOS 5 sshd does not log IP address of reverse mapping failure

These are messages about invalid users. I already wrote that I get these too, complete with IP addresses, even before putting in "UseDNS no". My question is about these: Feb 10 13:32:41 dns01 sshd[16161]: Disconnecting: Too many authentication failures for root Feb 10 13:32:45 dns01 sshd[16163]: Disconnecting: Too many authentication failures for root Feb 10 13:32:48 dns01 sshd[16165]: Disconnecting: Too many authentication failures for root Feb 10 13:32:53 dns01 sshd[16167]: Disconnecting: Too many authentication failures for root Feb 10 13:32:55 dns01 sshd[16169]: Disconnecting: Too many authentication failures for root Feb 10 13:32:59 dns01 sshd[16171]: Disconnecting: Too many authentication failures for root Feb 10 13:33:02 dns01 sshd[16173]: Disconnecting: Too many authentication failures for root Feb 10 13:33:05 dns01 sshd[16175]: Disconnecting: Too many authentication failures for root Feb 10 13:33:08 dns01 sshd[16177]: Disconnecting: Too many authentication failures for root Feb 10 13:33:11 dns01 sshd[16179]: Disconnecting: Too many authentication failures for root Do you have log entries with IP addresses for these? Oh, before you ask, the sshd which logged these runs of course with PermitRootLogin no PasswordAuthentication no > cat /etc/redhat-release > CentOS release 6.3 (Final) Notice the subject line? How it says "CentOS 5"? That was deliberate. -- Tilman Schmidt Phoenix Software GmbH Bonn, Germany

08 Mar '13

Hi all, I'm looking for an opensource solution for hosting webinars on a remote dedicated server running CentOS6. I would like to use FOSS, and it would be perfect if it's packaged, or at least easealy packageable. Please let me know if you have some suggestion. -- RMA.

nc not working as advertised
by Robert Moskowitz 08 Mar '13

08 Mar '13

I can't get nc to do anything worthwhile. In fact I can't even get the examples in the manpage to work. From either my C6 servers or my F17 notebooks. For example: echo -n "GET / HTTP/1.0\r\n\r\n" | nc medon.htt-consult.com 80 Gets no response. And looking into the access.log of medon shows no access by my client. I have tried the client/server on both -4 and -6 on a port I have enabled on my firewall. The server looks to be listening, but the client seems to never connect. what I typed in eventually gets played to the terminal session and of course bash says no such command. Say I have port 5902 open (for vncserver, and vncserver is not running). So on server foo, in a su session (because of the port range) I type: nc -4l 5902 seems to be listening. Then on bar, also in an su session: nc -4 foo.domain 5902 hello world After some time nc terminates and "hello world" gets sent to the su session and of course is not a valid command... So what am I missing here? Doesn't matter if I use -4, -6, or neither. It does not work.

netcat or netcat6 for Centos 6.3
by Robert Moskowitz 07 Mar '13

07 Mar '13

In my testing of HIP, there is reference to use 'nc6' for a simple TCP character echo server. No such animal in Centos, and after a bit of digging I find this refers to Netcat6 which seems to be a dead app? Is it available as an rpm somewhere for Centos? My searching is coming up empty. Or just about any service that I can start on one system and connect from another that would perform this simple echo test.

Replacing Multiple Servers with One
by Tim Evans 07 Mar '13

07 Mar '13

We are replacing four servers, running mail, web, ftp, and dns, respectively, with a single server to run all four services. The new server will have a new IP address. It seems fairly straightforward to redirect mail, web, and ftp services to the new server via DNS CNAMES, but I'm not quite sure about how to do the change for the DNS service itself. Is there a need to maintain the old DNS server's IP address during a transition, or longer? Via a virtual IP with the old DNS server's IP address on the new machine, perhaps? Or a second NIC with the old address? Or just have the router redirect incoming DNS requests? Thanks. -- Tim Evans | 5 Chestnut Court Linux/UNIX Consulting | Owings Mills, MD 21117 http://www.tkevans.com/ | 443-394-3864 tkevans(a)tkevans.com
