| 1 | More Rancid: |
|---|
| 2 | |
|---|
| 3 | (do this as the rancid user: su -s /bin/bash rancid) |
|---|
| 4 | |
|---|
| 5 | 1. Note the IP addresses for all the routers |
|---|
| 6 | |
|---|
| 7 | 169.223.142.11 - 169.223.142.18 |
|---|
| 8 | |
|---|
| 9 | 2. Update /var/lib/rancid/.cloginrc |
|---|
| 10 | |
|---|
| 11 | Change the file to look like this: |
|---|
| 12 | |
|---|
| 13 | > vi /var/lib/rancid/.cloginrc |
|---|
| 14 | |
|---|
| 15 | add user 169.223.142.* admin |
|---|
| 16 | add password 169.223.142.* apr10cot apr10cot |
|---|
| 17 | |
|---|
| 18 | (This tells RANCID that all hosts called "169.223.142.*" use the |
|---|
| 19 | same password and user -- no need to add every router by hand!) |
|---|
| 20 | |
|---|
| 21 | 3. Update the router.db |
|---|
| 22 | |
|---|
| 23 | > vi /var/lib/rancid/all/router.db |
|---|
| 24 | |
|---|
| 25 | Add all the routers above: |
|---|
| 26 | |
|---|
| 27 | 169.223.142.11:cisco:up |
|---|
| 28 | 169.223.142.12:cisco:up |
|---|
| 29 | 169.223.142.13:cisco:up |
|---|
| 30 | 169.223.142.14:cisco:up |
|---|
| 31 | 169.223.142.15:cisco:up |
|---|
| 32 | 169.223.142.16:cisco:up |
|---|
| 33 | 169.223.142.17:cisco:up |
|---|
| 34 | 169.223.142.18:cisco:up |
|---|
| 35 | |
|---|
| 36 | (Note that "cisco" means this is Cisco equipment -- it tells Rancid |
|---|
| 37 | that we are expecting to talk to a Cisco device here. You can also |
|---|
| 38 | talk to Juniper, HP, ...) |
|---|
| 39 | |
|---|
| 40 | 4. Run rancid again: |
|---|
| 41 | |
|---|
| 42 | > /usr/lib/rancid/bin/rancid-run |
|---|
| 43 | |
|---|
| 44 | (Should take a few seconds) |
|---|
| 45 | |
|---|
| 46 | 11. Check out the logs: |
|---|
| 47 | |
|---|
| 48 | > cd /var/lib/rancid/logs |
|---|
| 49 | > ls -l |
|---|
| 50 | |
|---|
| 51 | ... View the contents of the file: |
|---|
| 52 | |
|---|
| 53 | > more all.* |
|---|
| 54 | |
|---|
| 55 | 12. Look at the configs |
|---|
| 56 | |
|---|
| 57 | > cd /var/lib/rancid/all/configs |
|---|
| 58 | > more 169.223.142.X |
|---|
| 59 | |
|---|
| 60 | - If all went well, you can see the configs of ALL routers |
|---|
| 61 | |
|---|
| 62 | 13. Change the configuration on the router (change the description on |
|---|
| 63 | an interface, for example) |
|---|
| 64 | |
|---|
| 65 | 14. Run rancid again |
|---|
| 66 | |
|---|
| 67 | > /usr/lib/rancid/bin/rancid-run |
|---|
| 68 | |
|---|
| 69 | 15. Play with clogin: |
|---|
| 70 | |
|---|
| 71 | |
|---|
| 72 | > /usr/lib/rancid/bin/clogin -c "show clock" 169.223.142.11 169.223.142.12 169.223.142.13 ... |
|---|
| 73 | |
|---|
| 74 | (add as many routers as you want on the line -- don't type "..." !) |
|---|
| 75 | |
|---|
| 76 | - What do you notice ? |
|---|
| 77 | |
|---|
