Thanks for the advice!

comment SQUID Proxy in a thinclient environment
No it needs to be transparent to the user. If I could somehow force some pseudo authentication by hard setting the firefox proxy to user@proxy on login it will be fine.

Intresting. Thanks

ya sorry. Didn't know if it should be here or Server Fault. I'll remake. You can disregard this

comment Thin clients over WAN - Capacity planning
Thanks, but that gets you into a circular argument. You can't really know how much capacity you need until you test the system but you can't design the system without knowing what to buy. There are general "rules of thumb" that "people who've been doing it for years" just simply know. For example I know that Wordpress\Joomla sites with > 200k unique hits should be off a shared server. Shared servers (in my environment) tend to die after this point and we have to kick users off. I know they can also handle < 30 simultaneous HTTP connections. I know simply having worked in the environment.

comment Force failover a Cisco ASA
I want to force failover the two ASA units. I want the primary to become the secondary standby and the secondary to become the active primary unit. I want to do some maintenance then switch them back.

comment Force failover a Cisco ASA
This is how they are configured and this is how they stay. I need to fail them over temporarily.

comment Private VLAN configuration (With Diagram)
Would setting a current trunk port as a promiscuous port (essentially putting it in a PVLAN) mess with it's ability to trunk standard VLANs

comment Private VLAN configuration (With Diagram)
Thanks. So according to my example which ports should be set as promisc, which as a trunk, and which as a private trunk (if any)?

comment Private VLAN configuration (With Diagram)
Yes :). Sorry I wasn't more clear. In the topology above the lavender (vlan "10") hosts can not communicate with each other but must be able to communicate with the router on a stick. I was thinking of leaving everything as a dot1q trunk and having the ROAS configured on VLAN 11 (the isolated sub-vlan of 10). I believe the traffic is tagged as 11 and will be sent out trunks regardless of the promiscuity of the port.

A host can still use ARP spoofing or rogue DHCP to take over a segment. PVLANs prevent direct communication between the hosts in a VLAN thus preventing ARP spoofing and rogue DHCP.

I want true layer2 segmentation between the hosts (no direct communication)

comment Force proxy settings (Solaris\Linux)
Then where does firefox get its "Use system proxy settings" from?

comment SQUID Proxy in a thinclient environment
Thanks. I don't want to have to set up all the user database and stuff. That's why I'd rather somehow just stuff the username into a header. Anyway I can set per-user proxy settings that are applied upon login? I see that firefox has a "Use system proxy settings" bubble. If I could set the "system proxy" setting for each user to username@proxy:port I could achieve the same effect.

comment What's so special about leased lines (T1, DS3, etc)
Interesting points. I can see things like video conferencing\streaming being important considerations (for the upload and jitter you described above). For high bandwidth applications I can see the need for circuits on the SONET ring. For run of the mill internet access though I don't see the need. Hell I've seen call centers run off the cable co, VOIP and all.

comment What's so special about leased lines (T1, DS3, etc)
Yes but short of a piece of paper in all practicality the leased lines are near as likely to go down as the regular connections. Also you can get two different feeds from two different providers (say FIOS and cable) and still pay next to nothing compared to the DS3 with a more robust connection. The SLA doesn't seem to justify THAT much of an increase to where people pay upwards of $1000 for 1.544 Mbps.

comment Why do modern routers not require clock settings anymore?
Thanks. I thought T1 and T3 (could have) the same physical layer (coax). I didn't think there was a "ds3 card", I thought it could be used for a T1 or T3 connection in which case how would it know what standard to use? Back in the CSU\DSU days could you set the clock to whatever you wanted or did the telco still provide it? If so then I suppose setting clocking is only useful in the lab and for QoS as you said.
