| cmaloney | I'm still running Ubuntu 18.04. :) | 01:08 |

| jrwren | i do FIPS things at work. Ubuntu Pro makes that easy. Dealing with 1 distro keeps me on ubuntu. | 20:18 |
| jrwren | I’m trying to think of ways to resolve a name to an IP from cmdline in a restricted env. I would appreciate any ideas you have: | 20:18 |
| jrwren | host cmd - not installed in env and pkg not available | 20:18 |
| jrwren | dig cmd - same as host cmd | 20:18 |
| jrwren | ping - same as host cmd | 20:18 |
| jrwren | nslookup - same as host cmd | 20:18 |
| jrwren | getent hosts - not exactly resolv only, but I used it anyway | 20:18 |
| jrwren | call perl which is probably installed | 20:18 |
| jrwren | call python - same as host cmd | 20:18 |
| jrwren | busybox? | 20:18 |
| jrwren | other? | 20:19 |
| cmaloney | Telnet to port 53? :) | 20:21 |
| jrwren | it is difficult to write a DNS query and even more difficult to parse the response, else that would have been something I considered. | 20:43 |
| cmaloney | I know. I'm being slightly cheeky here | 20:47 |
| cmaloney | I mean, any language that has networking libraries will have something similar for doing DNS lookups | 20:48 |
| cmaloney | C, C++, etc. | 20:48 |
| cmaloney | Rust, | 20:48 |
| cmaloney | the 15,000 libraries that would make up a NodeJS DNS call | 20:48 |
| cmaloney | like some perverse fire-brigade | 20:48 |
| jrwren | sure, but what is easiest? do the simplest thing that works. | 20:49 |
| ben | busybox has nslookup in it | 21:20 |
| ben | what do you have access to? | 21:20 |
| === \subline is now known as \weakmayors | ||
| jrwren | It is a fips ubuntu20 container where a lot of packages aren't available. e.g. I tried to install bind-utils or something to get host or dig, but they weren't there, hence the question. | 21:55 |
