You can use: > /var/log/mail.log That will truncate the log without you having to edit the file. It’s also a reliable way of getting the space back. In general it’s a bad thing to use rm on the log then recreating the filename, if another process has the file open then you don’t get the … Read more
My usual solution for this is a plugin called WP Mail SMTP. The problem with this is that the plugin has not been updated in over 2 years. This means that issues with more recent versions of WordPress (although at present that shouldn’t be the case) and also means you are likely on your own … Read more
Solution Here is what I finally came up with after being set in the right direction by Miles Erickson. I wanted the address bar to reflect the original subdomain/domain of the request and not the redirected server and port, but he put me on the right path to Google up a solution using VirtualHost and … Read more
Yeah, you can do that. From curl –help or man curl: -k, –insecure (SSL) This option explicitly allows curl to perform “insecure” SSL connections and transfers. All SSL connections are attempted to be made secure by using the CA certificate bundle installed by default. This makes all connections considered “insecure” fail unless -k, –insecure is … Read more
I have tested this at home (~ 3 hosts) for some time now, trying different scms (RCS, Subversion, git). The setup that works perfectly for me right now is git with the setgitperms hook. Things you need to consider: Handling of file permissions and ownership RCS: does this natively Subversion: last I tried, you needed … Read more
If you’re logged in as root, you can easily wipe directories or do something that in retrospect is really dumb on the system with the flip of a finger, while as a user you normally have to put a few extra mental cycles into what you’re typing before doing something that is dangerous. Also any … Read more
This should work on Linux and SysV5 ps -ef –sort=start_time
I generally put something similar to the following at the beginning of every script (especially if it’ll run as a daemon): #!/bin/bash exec 3>&1 4>&2 trap ‘exec 2>&4 1>&3’ 0 1 2 3 exec 1>log.out 2>&1 # Everything below will go to the file ‘log.out’: Explanation: exec 3>&1 4>&2 Saves file descriptors so they can … Read more
This might sound like a silly idea, but if the users aren’t actually doing anything, you could do: cat /etc/passwd | cut -f 1 -d : >/tmp/users.list Then edit /tmp/users.list to only contain the users you want. Then do: for i in `cat /tmp/users.list` do userdel $i useradd -m $i done However, many Redhat based … Read more
Another option is to use the /proc filesystem. The /proc/net/dev file contains statistics about the configured network interfaces. Each line is dedicated to one network interface and it contains statistics for receive and transmit. The statistics include metrics such total number of received/transmittted bytes, packets, drops, errors and so on. cat /proc/net/dev Inter-| Receive | … Read more
