Feature #911
Updated by Daniel Curtis over 6 years ago
I recently wanted to add the IP address of my development FreeBSD VMs to the console pre-login prompt, sparing me the time of logging in just to @ifconfig@ once so I can @ssh@ into the VM. Unfortunately FreeBSD does not use @/etc/issues@ like its Linux counterparts, but relies on /etc/gettytab and uses /etc/issue as a shim for text without the use of any macros. /etc/gettytab. This is how I added the IP address of my machine to the pre-login console prompt on FreeBSD 11. h2. update-issue script Add IP Address to /etc/gettytab * Create an update-issue script: Edit /etc/gettytab: <pre> vi /usr/local/etc/rc.d/update-issue /etc/gettytab </pre> #* And add modify the following: <pre> #!/bin/sh # PROVIDE: update-issue # REQUIRE: NETWORKING syslogd # KEYWORD: . /etc/rc.subr IPADDRESSESV4=$(ifconfig em0 | grep inet | awk '{print $2}') for IPADDRESS in $IPADDRESSESV4; default:\ do printf "IP: $IPADDRESS" > /etc/issue :cb:ce:ck:lc:fd#1000:im=\r\n%s/%m (%h) (%4) (%t)\r\n\r\n:sp#1200:\ done; echo "" >> /etc/issue :if=/etc/issue: </pre> * Make the script executable: <pre> chmod +x /usr/local/etc/rc.d/update-issue </pre> * Start and enable the script at boot: <pre> echo 'update_issue_enable="YES"' >> /etc/rc.conf service update-issue start </pre> h2.
