Re: Possible to determine what host name an IP is connecting to from command line?

We have a Web server which hosts approximately 200 domains. I would like to know if there is a practical means of determining which of those domains a particular IP address is connecting to. Any ideas?

iftop just shows the domain as the name of the machine.

Re: MySQL crashing(?) occasionally ... don't know why

Ugh ... I had no idea we weren't using the standard package. Our server provider installed the atomic repository, I believe they said in association with Plesk (a garbage piece of software I can't wait to be rid of). # uname -rmi 2.6.24-2-pve x86_64 x86_64 # rpm -q centos-release centos-release-5-5....

MySQL crashing(?) occasionally ... don't know why

Every once in a while, our MySQL database goes down. I have not been able to determine a cause. The logs indicate a "Normal shutdown"?? As you can see, below, the "Normal shutdown" started at 2:00:24 p.m. Eastern yesterday. It appears that shutdown was all wrapped-up by 2:00:30, then I got an e-mail...

CentOS uses same default configurations as RHEL, right?

I realize this is probably a silly question, but I just wanted to verify my presumption that, not only does CentOS reproduce the packages from the same source, but that, where possible, CentOS also uses identical default configuration for everything?

Re: SYN cookies -- in need of some clarification

/etc/rc.local only has:
touch /var/lock/subsys/local

I guess if there's something non-standard that's changing the setting on us, it's probably Plesk (domain control interface).

SYN cookies -- in need of some clarification

First, it isn't clear to me whether SYN cookies are enabled by default in CentOS 5 ... in /etc/sysctl.conf , net.ipv4.tcp_syncookies is set to 1 on the other hand, /proc/sys/net/ipv4/tcp_syncookies is set to 0 ... are these settings in conflict? Does one override the other? Are both of these the def...

Re: sshd thinks it is not running

For the record, I was able to resolve this issue by issuing the following commands:

pkill sshd && /usr/sbin/sshd

sshd thinks it is not running

I have monit installed on our server to keep track of some things, sshd being one of them, and I started getting notifications 15 minutes ago about sshd being down and monit reported that it failed to start it. Well, I connected via ssh just fine and everything looks fine on the server, but I was st...
