comment Slow sudo and ssmtp (hosts file wrong?)
You're trying to fix the problem and jumping to conclusions without doing any diagnoses... I agree that such timeouts may very well come from name resolution trouble... Try a tcpdump on port 53 for example to see if it's doing DNS lookups that generate errors or the like: tcpdump -i lo port 53, tcpdump -i eth0 port 53...

Can you show the output of ifconfig and route once everything is up ?

comment VMware, LVM & Linux: Expanding a volume… temporarily, and without downtime
It's simply a question of volume. Say the filesystem has 40G, and they want to test stuff and temporarily need 80G. I don't want to say those additional 40G permanently goodbye since they don't need it permanently. OS is Linux as I said, more specifically SLES. Filesystems are usually ext3.

comment VMware, LVM & Linux: Expanding a volume… temporarily, and without downtime
Whether they are thin- or thick-provisioned you can always add/remove them on the fly from the OS, that is for sure. The advantage of an additional LVM layer is that you can add another VMDK on-the-fly by expanding the filesystem using a VMDK even if it comes from a different LUN (ok, you can also kind-of concatenate VMDKs). But all these insights still don't solve the main question which is how you can completely transparently expand and again later shrink a virtualized filesystem. The problem is the filesystem itself in the end. Maybe then simply the fact of using ext is the problem.

comment VMware, LVM & Linux: Expanding a volume… temporarily, and without downtime
That would be the option where I symlink or mount a second volume somewhere into the first filesystem, which I excluded being an option, because it's not sure exactly where the space is required. Also I don't want to have to shut down anything. Feel free to give me an idea of what more complex options you are thinking about :)

comment How can I detect if I have access to a resource on an FTP server?
One may add that for larger FTP scripts you may use Perl or similar, which would allow you to perform explicit error handling after each command.

comment Proper NTP configuration for a few servers
Won't hurt if you google a little about what a peer is. Note that this site doesn't serve anything on a silver platter when people do no research at all themselves.

comment Proper NTP configuration for a few servers
Usually you should have one or two internal time servers against which you sync your internal network. Your two internal servers can have a peer relationship. See for example ntp.org/ntpfaq/NTP-s-config-adv.htm#AEN3101

comment Sending automatic mail on ssh-login fails
If all your users use bash you might as well do this from the profile script or bashrc. I've done this in the past and it worked. Don't know about PAM.
