So today I re-upgraded the firmware of my existing firewall and fixed all my issues I had the first time around. At first it didn't work and I ended up phoning Cisco for help and a nice lady had some commands for me to try. I follow her instructions and all the commands she tries to put in were already set by me earlier that morning. Without actually changing anything all my of problems went away and it Just Worked. Awesome. That's about the first thing I've ever done that had a real implementation in an environment. I begin to prepare to move my new 5506 into the network, I undid the rats nest of cabling. Put some labels up on cables and since I had to introduce some very simple vlans as part of this (the 5506 has no switching capabilities of it's own, so I had to offload that to a dedicated device) I made sure everything was thoroughly documented. Suddenly the firewall that I had prepared weeks ago stopped working while it sat on my desk. Every time I'd plug into it directly to try some inband configuration, skipping the network entirely, I'd start getting IP address conflict errors. I ended up spending 90 minutes on trying to figure out what was going on that felt like maybe 10 minutes. Even trying a different computer, wiping the device and replacing the config, clearing arp tables, etc etc I couldn't figure out what was going on so I had to postpone putting in the real new firewall. Much to my boss's pleasure because he can't stop talking about how it's not going to be work because scary confusing vlans. I really hope it's not related to firepower because I don't actually know how to unfuck firepower at all. I tried to access it just out of curiosity and it started bombarding me with demands for configuration and I ended up just putting in garbage because I didn't know what to do. I haven't tried sw-module module sfr shutdown yet, but I'll have to tomorrow. Factory resetting the asa doesn't seem to affect firepower in anyway either so. I wish it just worked because I'm giving myself some pretty severe anxiety thinking about it; I have absolutely no idea what happened to it. I only have 18 days left to do my email migration, file server poo poo, DC migration, set up some proper OU structuring for a few hundred people, try to find some excuse to use powershell, set up vcenter, provision VMs, figure out the networking for the new chassis, etc.

I'd like to think that they would suffer major consequences but a lot of times they seem to just trudge along for a good long while until something bad happens and poo poo hits the fan. We actually were an MSP, the company we were farmed out to decided to cut the sysadmin contracts and farm it out to India. With us, they got decent enough work, but never great since we were getting paid so low(I made less than half the average in the area for someone with my job title last year) that people would use it to get in the door, then after 1.5-2 years leave for somewhere that paid what we should be. The couple of people who did stay on longer than that were all people who had started with the company right out of school, worked there 20-30 years before getting cut and being told to come back as contractors with severely reduced pay, since they are all afraid to try working anywhere else. Now it is all being farmed to India, instead of just the overnight poo poo, since they are literally paying the people in India 27 cents per hour(9k a year for 16 people to cover the night half of operations, ie 12 hours a day, prior to this, and an average time there of 6 months instead of the 2 years each they got out of us) The CEO came up through the ranks as a bean counter tho, so all that matter is bottom line. I shoulda known how hosed the company is when I found out they sold of the division that made calculators, and the division that did government black research.

This is a thing I've regularly encountered on ASAs. It goes from not working to working and there is seriously no rhyme or reason whatsoever. The last time it happened SSH just wasn't working at all so we blew the thing away and reuploaded the configuration a few times and boom it just started working on the third try.

lampey posted:CIDR was not used for a long time. Before thaip addresses were divided into different classes based on the first couple of bits. Ie, if the first bit is a 0 it is a class a network.(/8 network) In the 1st implementation of IPv4 in 1980 (RFC 760), the first octet was the network ID and the other 24 bits were the host address. It wasn't until the IPv4 RFC 791 in 1981 that what we recognize as modern IPv4 came about (it was implemented in ARPANET in '83), with implicit net masks based on the first two bits in the first octet. Class A was 00 = /8, Class B was 01 = /16, and Class C 11 = /24. Over the years and decades, more RFCs were added to the definition which added things like Class D (multicast networks) & Class E (reserved), reserved ranges in the network classes, loopback, CIDR, etc... In looking up the RFCs, I realized I didn't know what IPv1-IPv3 were. It turns out v1-v3 was actually TCPv1 - TCPv3 as IP addressing was integrated into TCP. When v4 rolled around IP was separated out and kept the version number. Honestly, the entire history of ARPANET is fascinating reading. I highly recommend starting with Where Wizards Stay Up Late: The Origins of the Internet and then reading other early histories like Casting the Net: from ARPANET to Internet and Beyond.

The first computer I maintained as part of my job was a Univac AN/UYK-20. Troubleshooting was done by flipping switches to input binary commands and reading the output, also represented in binary with LEDs. The normal operation was to input a series of commands that initialized a paper punchtape reader. That reader was used to initialize a magnetic tape drive reader. Always remember to have a bin handy to catch the punchtape or you'll end up with a long pile of tape.

Do you know how to script? In a language that's not shell? Now's the time to start learning python or something. Beyond that, it really varies on the industry. Maybe webserver config. Maybe (hopefully) config management. Maybe network troubleshooting. Maybe devops. Maybe some or all of these. It's really hard to say without seeing a requisition, since people tend to just dump anything involving Linux into "Linux admin" territory instead of the rather more descriptive titles Windows admins get sometimes. Expect to be a bit of a generalist, because the documentation will be horrible and everyone will blame you for everything, so you'll need to obsessively read about how they actually are terrible at their jobs and it's their fault (with attached tcpdumps or whatever). But that's every sysadmin job, really.

We also manage the financials; budgets, CapEx vs OpEx, forecast and actuals. We manage strategy for products and technology; what's current, emerging and subsetting. Vendor management also; either suppliers or outsourced contractors. Lots of spreadsheets and PowerPoint presentations and lots of meetings with other departments so we can try to track how our technology affects theirs and vice versa.

I'd strongly advocate for python, because it's performant, easy to read, has bindings for everything under the sun, has good linters, and translates well away from administration if you ever wanna move. Perl's ok. But be careful about putting it on your resume, because then someone will want to hire you as a perl maintenance programmer. Shell is bad and should be avoided. It's fine for small stuff, but getting used to doing small stuff in a better language will make you just stop using shell, which is good. It's not fun to worry about weird parts when quoting variables, and writing complex scripts in bash will wind up with you using bizarre ${i#...} bashisms that are impossible for other people to look up now that Google does badly with finding garbage

I'm learning perl first just because I spent so much time in a legacy environment it was the only non-shell language I knew would be there, much the same reason I learned vi over any of the other options. The alternatives are there on almost all modern systems, but not so much when you are working on systems that haven't rebooted in 3000 days.

That's basically the same reason I learned perl (vi is a solid choice everywhere, since it's guaranteed to be on every system). There's not anything wrong with it other than the recruiter mails I get from people who see perl on my resume.

I've been thinking about going back to school recently to get an associates in IT. For reference I already have a bachelors in a different field, but I'm sure at this point that I don't want to be in my current line of work for the long haul, so I'm looking to change fields. Is getting an associates a bad call vs. just working towards certifications, or is it reasonable to get an associates in addition to working towards certs?
