Centos sunucuya login olduğunuzda sunucu hakkında bilgilere hızlıca erişmek ve sunucu hakkında notlarınızı görmek istiyorsanız, aşağıdaki script tam size göre,öncelik ile yapmanız gereken;
/usr/local/bin/custom_motd adında aşağıdaki script’i oluşturup açılışta bu dosyanın excute edilmesi için;
/etc/profile dosyasının son satırına;
/usr/local/bin/dymotd
dosyayı konumlandırdığınız dizin ile belirtmeniz gerekiyor.
script’ten anlaşılacağı üzerine Maintenance Information kısmında /etc/motd dosyasına ne yazarsanız buraya yansıyacak şekilde yapılandırılmıştır. Bunun için extradan /rtc/motd’nin okunmasına gerek yok. Bunun için, /etc/ssh/sshd_config dosyasında;
PrintMotd yes satırını PrintMotd no olarak değiştirmeniz gerekiyor. Böylelikle hem motd dosyası hemde /usr/local/bin/dymotd ikisi birden okunmasın.
