comment Kernel panic after boot Centos 6.5 HP DL320 B120i HPVSA
CentOS 6.5 minimal kickstart install was totally broken for me, exact same symptoms. After trying out myriad solutions to workaround the issue, I gave up, just kickstart'd CentOS 6.3 (which has always worked) and then yum upgrade'd to 6.5.

comment Cisco: Route Outbound SMTP Traffic on Same IP as Inbound
it's all or nothing with object-groups, you can't specify a single static route as you are suggesting. I would have to specify smtp, http, ftp, etc. separately and it will do nothing to solve the problem, have already tried the explicit track. The problem, as stated in the linked thread, is that outbound smtp port is not at all guaranteed to be port 25; and when it's not 25 (like always), the implicit static route for smtp protocol is ignored, and the default is used instead, which just so happens to be the external ASA IP -- totally f-ing useless as far as serving legit mail is concerned ;-(

comment Cisco: Route Outbound SMTP Traffic on Same IP as Inbound
Thanks but check out the object-group, it already does that implicitly for services listed (smtp, www, https, etc.). The problem I think is that the ASA takes inbound smtp on port 25, but sends outbound on a huge port range (i.e. not necessarily 25). See article I linked to

@tombull89 thanks for the clarification, forgot about SuperUser.

comment Is Firmware OS Independent?
In what way on earth is this question off topic? While the answer is likely obvious to those who voted to close it, the question might be of some value to those of us who, while google'ing for an answer to said question, were not able to find any definitive answer as to the dependency relationship between OS and installed firmware.

+1, fair enough, nothing critical listed, but sounds like there may be some benefit. It's now or never as Fedora is going on to-be-formatted drive shortly.

sorted, additional mysqltuner.pl created mysqld process must have been the culprit

comment MySQL: Increased buffer pool, ibdata1 corrupt?
Going to wait until this evening before I attempt a restart as the service is up & running reads/writes "seem" fine. When I made the my.cnf change I did notice several mysql processes running, at least 1 of which was a separate mysql> terminal session. The culprit may have been mysqltuner.pl which I had run a few times today; it requires one to login for the script to run, so there may have been a couple of extra mysql process running as a result

comment MySQL: Increased buffer pool, ibdata1 corrupt?
Perhaps mysqltuner.pl or being logged in to a separate terminal to mysql> session had something to do with the locking, not sure. At any rate lsof shows "mysqld 23922 mysql 3uW REG 253,5 144703488 104 ibdata1" root mysqld_safe and mysql mysqld are the current running processes

comment How to tell if mod_deflate is actually working?
apache 2.4 upgrade doc seems to indicate that it will automagically determine whether or not to gzip a given resource: "mod_deflate will now skip compression if it knows that the size overhead added by the compression is larger than the data to be compressed" -- httpd.apache.org/docs/2.4/upgrading.html

comment CentOS 6 Kickstart Minimal Install: for JVM, MySQL, and Apache VMs
I wound up going with base + a few odds & ends -- works fine, great in fact, kickstarts are so very useful in VM environment ;-)

comment CentOS 6 Kickstart Minimal Install: for JVM, MySQL, and Apache VMs
Thanks, I'll go with minimal install (REMI must be quite up-to-date if it has latest httpd, mysqld, and jdk)

comment CentOS 6 Kickstart Minimal Install: for JVM, MySQL, and Apache VMs
"relative bloat", mostly due to the fact that I don't know the actual footprint; if minimal installation is under 1GB, fine, can roll with that, but like the idea of having a streamlined set of packages suited to the VM in question, particularly the primary (and only) service that it will run (httpd, mysqld, and java respectively)

comment CentOS 6 Kickstart Minimal Install: for JVM, MySQL, and Apache VMs
+1, but yikes, that may be a bit too lean; how about networking, ntpd, logrotate and likely many other necessary packages to run the virtual stack I have in mind? Fairly noob-ish as a Linux sysadmin, but I know enough to know that it might be a good idea to actually kickstart with some packages ;-)

comment CentOS 6 Kickstart Minimal Install: for JVM, MySQL, and Apache VMs
+1 agreed, but it would be pointless to install, for example, a web-server on a dedicated MySQL VM, even though it and similar extra packages consume a marginal amount of disk space. It's petty I know, but I'd like to find a sweet spot to start with in a true minimal install, and then build from source the primary service (mysqld, httpd, java) on each VM without having the relative bloat. I'd also like to see how lean I can reasonably get the base install as total disk space used is unknown at this point.

comment Apache RewriteCond: inject string into URI between regex match groups
brilliant, this little nugget of gold "(/|$)", never occurred to me to match trailing slash and string termination in that way. Also, your approach is better: while date-enabled URIs are few, they receive most of the traffic; therefore, as you say, better to match twice than thrice ;-)

comment Apache RewriteCond: inject string into URI between regex match groups
also, URI will be in form of /foo, /foo/id, /foo/id/id2, and date embedded versions that do not require date injection: /foo/date, /foo/date/id, /foo/date/id/id2. Need to handle trailing slash as well, but anyway, curious to hear your thoughts on chicken & the egg regex, I suspect it's more efficient to check for the pages first, and then check if uri contains date
