It's been a long time since I worked with SNMP so can't really help there. Being able to batch all the commands would probably speed it up a little bit, as you spend a significant amount of time just handshaking when you do them one by one.

Another thing I noticed just now: the parentheses inside the backticks are redundant, they force a subshell to be spawned within the backticks for no good reason.

No, it's a pretty decent script. Beginner scripts are often ways too overcomplicated but this one is straightforward and you don't seem too confused about how to do things. If you can avoid the backticks then that's probably a design improvement, but that probably requires you to find a different SNMP command.

scp is slow

All of the sudden scp got really slow ... from 2-3 seconds to 30 seconds. This happened for 5 hours, and then it went back to running fast. Why? If I use the -q qualifier which "Disables the progress meter" could this have any adverse effect? Thanks (1 Reply)
