Everything appears normal in the FTP server’s log:
fr01-srv proftpd[5591]: 192.168.0.1 – USER testuser: Login successful.
However, in Filezilla things are different:
Error: Connection timed out after 20 seconds of inactivity Error: Failed to retrieve directory listing
This is a very short helping tutorial explaining how to get gammu working with an USB 3G modem (in my case a Huawei K3565) in CentOS to later use in sending out alert messages for critical events.
Using basic network commands comes very hand when one needs to debug a networking issue, to fix a problem or to simply try out a couple of things.
This post is in no way an exhaustive list of Linux network-related commands, but tries to include a couple of the most basic ones and explain what they do.
You sometimes need to password protect a folder or an entire account/website from direct access. That’s easily done with the appropriate .htaccess file in the protected folder plus the mandatory .htpasswd file with the correct user and password combination(s).
But what do you do when you want to enable direct access to a subfolder of the protected folder?
The weirdest errors are those occurring on a freshly installed system where you’d expect for everything to simply work (with the default configs). But such new installs rarely work.
Roudcube successfully connects and sends emails through localhost. At the same time, external clients are unable to send emails through SMTP. The issues is…
Main symptom of a problem is that emails are visible in the Read User Mail utility in Webmin but they do not show up in either webmail (Roundcube/Squirrelmail), Usermin or any email client configured to connect to the server.
After further inspection, it appears the emails get delivered to /var/mail/usermailbox@domain.tld instead of /home/username/homes/usermailbox/Maildir.
Guest wireless access is handy when you want to separate guest devices (your friends’ phones and laptops) from your own devices connected to the main network.
To get started, you need a router capable of guest wireless (not every router can do this) already set up and running either DD-WRT or Tomato. This tutorial explains how to set up a router running Tomato that is used only as access point (WAN is disabled/unplugged).
One can never have too many backups. There’s always room for one more backup. Backups are what keep computers running (most of the time)… Except when backups are not set up. At all. Not even a single antiqued copy exists of what broke down…
Let’s imagine that worst case scenario. Let’s imagine…
The thing I love about Thunderbird (and its sibling Firefox) is that to transfer a wholly configured instance from one computer/system to another all one needs is to copy over the contents of the profile folder.
However, on the path of a Linux to Windows migration I discovered the oddity that Thunderbird will neither connect to mail server not prompt for password…
After setting up a headless VirtualBox environment on your server, there comes a time when you realize you’ve been using the same old version for so long… that updating doesn’t sound so bad.
If you’ve installed VirtualBox from the repositories, you might enjoy an (almost) painless update procedure. Or not…
Start by making sure…
AWstats updates work fine for all other domains on the server. The cron task is there and is correct. Manually running from command line completes very fast (2-3 seconds).
Among a ton of other reasons, AWstats may fail to run if a previous collection crashed while running and…
When using a system to host your important (or critical) operations, being able to get informed of issues while you’re away is a very handy function. Email is good for notifications, but it isn’t always fast enough (and constant checks drain battery power).
SMS on the other hand, is an almost instant alert method and although length-limited, should do the job just fine for those very important, must have alerts. For this setup you will need…
