    any opinion on using mutt?

    hello - i am trying to use mailx to send an attachment. unfortunately, the mailx documentation seems to be inconsistant. for example, the only way i have found to access google smtp mail is using Notice uppercase "A". Using the uppercase "A" is not documented in very many places from what...

    is this good news or bad news??

    hello - it appears that Centos8 is dying even before it begins, and is being replaced with a "Centos-Stream" service. from what little i know about it, this appears to means that updates will happen automatically, and stability may no longer be an assumption. has InterServer considered this...

    hello all - once in a while, i have found a rogue unauthorized script that somehow landed on my server. (probably because of WordPress) so after John Q kindly introduced me to the sha256sum command, i thought about a way to monitor activity. this is what i came up with (below). i thought i...

    mailx question specifying content-type

    hello - i remember John Q told me to quit using sendmail and use mailx instead, i think perhaps he mentioned security issues? lately Gmail is occasionally coming through as just a "noname" attachment with google. i have researched two workarounds (i am merely emailing the server date as an...

    mariadDB 10.4 and passwords note

    hello - it appears that with 10.4, when you are logged in as the root user, root access to the mysql CLI bypasses security. i suppose this makes sense, but it took a bit of research to figure out why the root password was being ignored. this works to change while logged in as anything...

    centos 8?

    hello - i just saw that centos-8 is now available. is this something that IS will be offering soon, or does it already? is there anything in c-8 that is motivating enough to start looking at it? or is one better to wait a year or so for all the issues to be resolved?

    php upgrading on centos 7

    hello all - for some reason, the people at centos-7 just love to use a php version that is near obsolete. and from experience, just upgrading php without being VERY careful seems to cause its own set of issues, like deprecated code suddenly causes errors. anyways, it appears i need to move...
