thanks, can you run it again without --skip-broken? I see it's still in your command. Also, what distro and version are you running?

comment How to exclude given lines in syslog-ng?
I found that I needed to enclose those matches in parentheses to apply the AND condition properly, e.g. not (match("PFILTER-DROP") and match("DST=192.168.202.255") and match("PROTO=UDP"));. Otherwise it seems to have more of an OR effect.

comment Failing to block brute force ssh with iptables
I recommend fail2ban to handle blocking IPs that are showing brute force attempts. It's easy to install and configure. I know it doesn't answer your question directly, but it might save you a few holes in the drywall.

comment Kipmi0 eating up to 99.8% cpu on centos 6.4
Rebooting the service processor on the machine worked for me. I'm also running CentOS 6.4 and the machine is a Sun Fire X4140. The kipmi0 process went down to almost zero per top.

@JoelDavis, can you summarize that article plus your earlier comments in an answer here? I'll accept it then. I think its suffice to say that it is not causing additional overhead, at least in my case. i.e. these calls have always been there, but now its just that the counter as shown in nfsstat is being incremented.

comment Slow NFS, nfsstat -c: what is authrefrsh (aka newcreds?) field about in detail?
@JoelDavis sounds like I'm using AUTH_SYS then. On the server end, we have to allow the client's IP when setting up a new client to be able to mount a share, but thats it. As far as I've read, thats the only authentication thats done with NFS version 3.

@JoelDavis I'm not sure what type of authentication I'm doing. I'm using NFSv3, and I don't believe I have many choices in that department. I can do an strace and find out whats going on behind the scenes, if thats more of what you're asking.

Theres a Red Hat knowledgebase article here, but I don't have access to it. If someone does, they could paste it as an answer here and collect a handsome bounty.
