With the whole transition to libera.chat for irc and taking some time off from work, I've taken to hanging out there a bit, and this is a common thing I'm seeing in the #networking chat. I'm seeing a lot of devs showing up in #networking asking for hosting/sysadmin stuff lots, ala "how to make apache do x", or "how do I automate my servers", which I find weird as that's sysadmin stuff normally (to me). Oddly enough it's a pretty diverse crowd of folks that are kinda hybrids, done networking, done sysadmin, some are php/web devs, etc, but lots of system-centric stuff so it tends to work out for info seekers. I suspect if I went into #sysadmin or like, they'd know nothing of networking, but #networking tends to come from diverse enough roots they do this stuff too, or did at one point at least.
Moral is, there's a lot of crossover these days, and folks need to know some dev, some sysadmin, and some networking. The line blurs, but people can't just be like "well, I only do mssql or active directory" anymore, they're replaceable with shell scripts. I've done unix/linux, some dev, some dba, some windoze, everything between along with a strong focus and experience in networking, and it's paid dividends as I figure out what others don't as a result.
Comparing to the OSI model of networking, I work mostly layer 1-7 up, but most dev/app/sysadmins work layer 7 down, and really have no idea below around layer 5 or so, much to their detriment. Best these days to be well versed across the board to some extent. Take a ccna class online, even if you don't get the cert, you'll probably understand things a lot more to make your life easier.
