I'm up to reinstall Arch on my laptop while I have a bit of a time and I've encountered an interesting question to ask.



Is there any way to check my laptop battery status without installing acpi package? (as I'm currently offline without charger and I can't get neither of them)



I thought that system should keep track of a battery level somehow. So is it possible to display that info in CLI?






arch-linux console

    Have a look at the files in /sys/class/power_supply/. May or may not work for your particular hardware.

The kernel provides this information through /sys/class/power_supply/BAT0/capacity



Simply cat this path to get the information (in percent of your batteries capacity):



cat /sys/class/power_supply/BAT0/capacity


For an live view you can combine cat with the command watch. The following command provides you a an, updated, live status of your batteries capacity:



watch -n0 cat /sys/class/power_supply/BAT0/capacity

            Postfix configuration issue with fips on centos 7; mailgun relay

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
