When I try to SSH to a host on the network named storage, I get a DNS resolution failure:
$ ssh storage
ssh: Could not resolve hostname storage: Name or service not known
But when I query DNS with host, it works
$ host storage
storage has address 192.168.20.103
How is it that host can find the IP but ssh cannot?
A user of mine came to me with a question today that has me stumped: Why do .musecore files on our web server show a bomb icon (
) instead of a folder icon?
More generally, how does Apache decide what icon to display, and where can I inspect and/or change that configuration?
Just read a Slashdot thread on LDAP brokenness on OSX. Can anyone explain exactly what is being secured by OpenLDAP and why anything other than data stored on a Lion machine might be at risk?
A quote from the article:
“As pen testers, one of the first things we do is attack the LDAP server,” Rob Graham, CEO of auditing firm Errata Security, said. “Once we own an LDAP server we own everything. I can walk up to any laptop (in an organization) and log into it.”
How does one go from hacking a random mac LDAP server to owning the entire enterprise?
I'm setting up LDAP authentication on my personal VPS, and Ubuntu has two packages for the same purpose: libpam-ldap and libpam-ldapd. Which should I use?
Debugging a Nagios warning on ssh, I've discovered that gssapi-with-mic is causing long lags in authentication. I've turned it off, but what exactly am I missing? I gather that GSSAPI is a tool for authentication, but what about the -with-mic part?
I'd like to be able to schedule a server reboot at a specific time, but not regularly. How can I do this without futzing with adding and removing cron entries?
Exactly what part of the disk is a UUID stored on? MBR? Somewhere within the partition? Is it a calculated value, or randomly generated and recorded?
IT is full of heroics; many of us carry a paging device, like Batman waiting in his cave for the Bat Signal. What's a fair compensation for on-call schedules? Is it acceptable to handle emergency requests on weekends or vacations?
I've got two snmpd.conf files, one on a server that works, and one that doesn't. How can I diff the two config files while stripping out irrelevant comments and newlines?
IE7 aggressively warns about certificate failure; we have some internal sites that run over HTTPS and thus need a valid cert. We appear to have an certificate authority on the intranet that can sign SSL certs, but we have a problem: how do we mass configure desktops to trust the internal CA?
Is it possible to deploy the internal CA cert locally, via GPO?
Vendor binary package format selections appear to be determined by a form of Murphy's Law: all the distros you don't use have packages. (Corralary: there exists no distribution that satisfies your software stack's distribution dependencies).
Is this a matter of politics, or something deeper, that we haven't seen the emergence of a "build once, run anywhere" package format?
Given a default instance of Ubuntu Server LTS, how many additional resources are needed to run a Mumble server ("murmor") for say 10 connected users?
I'm curious about:
Information on marginal increase per user is also welcome.
There's six instances running on my desktop, and probably ten on a server I manage. What is this, and is it vital to system function?
I've got a box running Win2k3 and some directions from Microsoft KB about SSL certificates, for IIS 5.0 and 6.0. How can I tell which version of IIS is currently installed?
Given a partition intended solely for storing music, video and so-on, is it possible to hide the lost+found directory?
Using a NAS box as 24/7 file server, I'd like to use sshfs to connect to it from an Ubuntu 9.04 desktop. Currently, I have this line in the desktop's fstab:
sshfs#jldugger@storage:/mnt/HD_a2/ /mnt/storage fuse comment=sshfs,auto,users,exec,uid=1000,gid=1000,allow_other,reconnect,transform_symlinks,BatchMode=yes,fsname=sshfs#jldugger@storage/mnt/HD_a2/ 0 0
I can confirm it works with mount /mnt/storage. What I need is some method of mounting it at startup, but after the network connection is established.
Sometimes your scripts need to behave differently on different Linux's. How can I determine which version of Linux a script is running on?
Should we remove the root password, disable remote login and basically require adminstrators to use sudo to perform administrative actions?
When someone mentions RAID in a conversation about backups, invariably someone declares that "RAID is not a backup."
Sure, for striping, that's true. But what's the difference between redundancy and a backup?
