comment Slow sudo response
- Huge config files? Not really, /etc/openldap/ldap.conf is 399 bytes, /etc/pam_ldap.conf is 8,937 bytes. - Is name resolution working properly between hosts? Yes, client running "time dig $LDAPSERVERNAME" returns in less than 0.01 seconds, as does the "time dig -x $SERVERIPADDR". From the server, doing the same to the client name/IP is equally as fast and accurate. - Have you changed the hostname since installation? No the client has been named "redhat357" since birth. - And, what is your hostname? The problem is across numerous machines, but in this case it is named "redhat357".

If you see the GET requests reaching your firewall, but you can't monitor the outside connection on the firewall yourself, you'll need to work with them - they should be able to setup some monitoring on their end to capture the traffic that's making it to their side.

comment Troubleshooting Website problems within the local network
I would expect odd problems to appear elsewhere too - that's what has me at a loss for a specific "check X" sort of answer. Have you tried any of the data collection steps? Even sniffing the inside port on the firewall will confirm that it's not completely due to an internal networking issue.

comment Troubleshooting Website problems within the local network
I agree that it doesn't look like a routing issue, but it's quite possible that it's a packet dropping issue. By using a packet sniffer on the outside of the firewall you can show that the GET requests that ultimately fail did leave the network. You would then have some data points to prove that it's not a problem on your network.

So, if you put a WireShark sniffer outside your firewall do you see the GET request going out? If not, then your problem is internal and just needs to be tracked down. If it goes out, then you'll need to work with your ISP and hope they will work with you.

comment Source of PDU De-Rating?
Seconded. The 20% buffer is to account for surges when systems are coming up, and for slight variations in the circuit breakers, wiring imperfections, etc.

comment SNMP Extend not working
The "No Such Object available" leads me to believe that the UCD-SNMP-MIB::extTable may be incorrect. Other on-line examples show using NET-SNMP-EXTEND-MIB::nsExtendObjects. From this RedHat example.

comment SNMP Extend not working
Just checking the basics: is the check_lag_quietly.sh script set as executable, and is it and the entire /usr/local/bin/ path have the read and execute permissions set correctly for the user that the snmpd daemon is executing under?

comment Juniper J4350 out of order
I'd suggest removing all but the necessary cards, then re-seating them one at a time with the console plugged in. Can you test/confirm the console cable is ok by testing it on another Juniper switch? (I have experienced cables "go bad overnight", but in the end we found that the cable head got pulled hard and some wires broke.)

comment Acceptable use policy / computer use policy / network use policy - why are they needed?
It also applies internally, too. HR needs to have a set of guidelines to point to if an employee is doing something that isn't appropriate for the workplace.
