Why can't I SSH into this router? Is something wrong with the OSPF configuration?ip dhcp excluded-address 172.16.49.129

Try asking me what GPU to buy at a certain price point, sorry.

Aw man great tech question!
>>59290108
I've got about 500$, currently have a 390x, paired with a 6700k for what it's worth. No point in upgrading, right?
>>59290393
Stop talking about what shitey graphics cards you wanna buy and help me with my SSH problem
>>59290462
Sorry Anon, I, like most of /g/, am merely a consumer pleb. Wasn't talking to you OP, mind you.
>>59290523
I know, I'm just bumping my thread in hopes that someone understands this and can help

Can you provide more details?

>>59288599
What do I win if I hack it?
>>59291406
It's open and listening, it can be pinged and can forward packets to the correct destination.
I'm trying to SSH via vlan 1 (172.16.1.12 in this case) but the connection times out. It dealt with SSH fine from a pc/vlan on 172.16.49.130 before OSPF was implemented however, I'm not sure if the 172.16.1.12 address will need to be changed to deal with this though.
When I attempt to SSH, the connection times out.
>>59291412
all these pancakes
You probably didn't generate RSA keys on the router.
>>59292132
Also just get a braindump to study for your CCNA and stop wasting your time. That's what literally everyone does.
>>59292132
Obviously I did if it worked prior to the OSPF configuration.
>>59292152
Not doing a CCNA either, it's for uni.
>>59292170
>Obviously I did if it worked prior to the OSPF configuration.
Don't expect me to read the thread nigger.
If it's a physical router then set up a port-span or plug a hub into the path and run a packet capture to see what the fuck it's doing.
If it's virtual then whatever platform you're using should have a packet capture feature or it's ass.
You're asking if something is wrong with OSPF and you're not even giving any information about your set up.
Are you relying on an OSPF route to get to this thing?
Post a topology diagram.
Post source and destination addresses
Post your OSPF database, neighbor, and topology tables
Post your route table
Run debugs on the router and post the output
You're one of those assholes who will eventually get a job, and whenever something breaks you'll email your contracted IT support and say "hurr it no work pls halp".
And most of your wildcard masks are wrong and you're not even advertising all your networks.
>>59292702
I'm asking if anything is wrong with that router configuration for SSH and if maybe OSPF was a part of that problem maybe because of the network address and the wildcard for it.
I mean, I'm still pretty early on learning this shit. Most people in my course wouldn't bother to take free time like this to fix stuff.
>>59292702
Source is 172.16.49.130 to SSH into 172.16.1.12
>>59293523
honestly when I did Cisco stuff the one thing I had a hard time getting to work was telnet and ssh stuff
You probably need to generate RSA keys, I'm not exactly an expert though, I'm still learning as well
>>59292152
>braindump
What is this exactly? I've heard about CBT nuggets and resources like that, I still gotta take the exam but I dont feel very confident I can nail it first time like I want to
If Braindump is its own thing it would be nice to get info for other exams as well, I still gotta take Network+ and a bunch of other stuff a friend recommended
>>59293523
Dear lord that is fucked up - did your professor make that topology?
Anyway it's kind of hard to tell without being on the router but I don't see how OSPF could be a problem here - 172.16.1.0/26 and 172.16.49.128/26 should both be connected routes so OSPF shouldn't come into play. If it really broke when you configured OSPF then take out the OSPF config and see what happens.
>>59296091
"Braindump" is just a catchall term for question and answer dumps for exams. There are companies that pay people to take exams and memorize the questions so they can sell them online. They're to find with some googling
I'd only recommend using them if you have experience already and just want the cert - it's REALLY easy to expose someone in an interview who cheated and doesn't know their shit.
