I've been asked to locate files created 80 days ago and calculate the space they occupy, for a few different filesystems, which is normally easy to do with the "find" command, such as: # find . -mtime +80 -exec du -ks {} \; | cut -f1 | awk '{total=total+$1}END{print total/1024}' But, in this...

We recently did a clean install of Oracle Solaris 11 on our older x4540 THOR/thumper system. The purpose of which is to export a large iSCSI LUN for emergency use. Following the instructions on: http://docs.oracle.com/cd/E23824_01/html/821-1459/fnnop.html I was able to create the zpool with...

I've set up OpenLDAP 2.4 (CentOS 6) and SSSD. I'm able to authenticate regular users -- I imported the LDIF using {CRYPT}password. However, I established a "role" account for general auth reads and it won't work. ldapsearch is not working for anything other than Manager, regardless -- of...

Where I work, we primarily use Linux systems and Nagios to monitor them. The way we monitor via Nagios for NFS mounts on a client system will not work with OSX (/proc, /etc/mnttab, etc). I admit my OSX tech skills are not yet up to par, but we do have a couple of these that are in production...

We have a remote mount point that we are copying files to. Presently, with a single instance of rsync. The file tree has 100s of files -- what I'm trying to figure out is how to split that entire job up and use, for example, three connections to maximize our bandwidth and perhaps get the...

I'm new-ish to kickstart. I've been spending some time trolling through docs on the Internet and I can't seem to find a reliable example of how to configure the network interfaces (plural) in a %post script. Seems that RH deprecates things in anaconda (bootproto, asknetwork), and those options...

We are using the stock samba (/usr/sbin/smbd) that comes with Solaris 10 for a basic network share, which works. I was working on adding a user, the /etc/sfw/samba/private directory has *.tdb files that get updated, but smbclient will not authenticate. Turns out, it appears that it's...

We had an issue recently where our NAS needed to be powered down for some building maintenance, a couple client machines had some problems. Long story short, a couple of Hadoop servers that use a backend, point-to-point interface to the NAS didn't come up, because of a mistake in NIC settings...

We are rolling out Hadoop nodes. I'd prefer to keep and manage the configuration for each system outside of the HADOOP_HOME location. There is HADOOP_CONF_DIR which can be set - but it's not really clear to me, after reading the scripts and some docs, where the best place to set this is, so...

I have an ASA 5505 at home for which I want to configure a VPN to the Cisco ASA 5540 at work. Problem being, I have Comcast as an ISP and my IP is dynamic. I know I can configure a tunnel and just go in and adjust if the IP happens to change. However, we have a number of other production...

We have an issue with a Mac OS X Lion NFS client that "should" be resolved using no_subtree_check to the NFS export attributes. Unfortunately, when I go to change these attributes in ZFS (Solaris 10), I get an error: # zfs set sharenfs=rw,anon=0,no_subtree_check zpool1/name cannot set...

We have about 23 VoIP phones that I need to set up mirroring for on a 4200G switch for technical monitoring and diagnosis. The brand has the same three HEX numbers, but the documentation doesn't really say much about mirroring multiple MACs or whether I can use just the first three HEX numbers...

I've configured logrotate to handle one of our development logs. But, it's not really behaving as I would expect. Here's the config: /var/log/dce/*log { missingok size 100M create 0644 filecopy staff notifempty dateext compress } Here's what happens when I run it manually: #...

We have a point-to-point fiber that connects two thumpers across site which is used for replication of data. Normally this is just a matter of two interfaces, no route and no problem. However, on this system (Solaris 10), when the system reboots, we end up with a route that completely shuts...

We've encountered an issue with RHEL where the chkconfig settings of some daemons (that were previously configured via --add) seem to be removed from startup. I'm looking for a way to monitor these -- perhaps with a Nagios script (we use Nagios internally, so that makes sense). This may be...

We have a Sunfire thumper x4520 with Solaris 10 that I will eventually be tasked at migrating functions to Linux. The primary function of this system is NFS, it serves as our central NAS. I've seen some references to using DRBD, which is a possibility. However, I wanted to get some...

We have a few 3com 4200G switches that are daisy chained (which I know is the incorrect way to connect them) together. The FAULT LED has been on, on 3 of them for a while, even after a reboot. Looking through the GUI, I can't seem to find anything that indicates a problem. Of course, the...

We have a Sun x4540 thumper that we use for central NAS storage. To date, I have had nothing but frustration with Sun's implementation of cron. It seems like it's pretty darned old. Regardless, something like this should just work: 0 0,2,4,6,8,10,12,14,16,18,20,22 * * *...

I need some advice on handling our new zpool (Solaris 10). We first received the x4540 thumper which came preconfigured with raidz, which worked fine. Then, someone in our dept decided we needed Veritas, which ended up not working out (I hate that product anyway). Now, we're backing out...

Our Solaris 10 server is a SunFire x4550, running Solaris/Generic_141445-09. We use NFS heavily in our environment. The options we use are simple: "tcp,hard,intr,bg,rw" (vers=3) We have one directory where files are written to and deleted which sometimes (not always) leaves behind a ton of...
