Same here - it's slow for me using Firefox, IE, or Safari. In fact, "slow" is not the word - "slow" is a few seconds rather than an instant response - this wait is "interminable" ;-)

> If your network is broadcasting a bum IPV6 route

Not my area - I've contacted our Network guys though to ask if this is a possibility . . .

When I asked about it, apparently there's something about the federation WAYF and IPV6 . . . it tries to follow the route, fails and falls back to normal IP

If it's a federation WAYF issue, wouldn't we see this delay with other services going through the WAYF (which we don't here - does anyone)? Why is it only these SDSS resources that take so long to respond through the WAYF?

I would suggest that, whatever the problem is, it needs to be properly identified and rectified (wherever the issue lies) - if I was running a service that took this long to respond, I would be taken out and lynched by our users ;-)

It's not a browser thing Mark. It's been slow for us for a very long time on all browsers. When I asked about it, apparently there's something about the federation WAYF and IPV6. If your network is broadcasting a bum IPV6 route, that will cause the delay, while it tries to follow the route, fails and falls back to normal IP. Not sure if that's still the case though.

No, not just you two. I think I'm seeing the same issue when hitting NFO, ie: a very long lag before being prompted to authenticate, or a complete and utter failure:

https://sp.edina.ac.uk/nfo/Shibboleth.sso/WAYF/UKFederation?providerId=https://shibsles.brunel.ac.uk/idp/shibboleth

"Safari can't open the page "https://sp.edina.ac.uk/nfo/Shibboleth.sso/WAYF/UKFederation?providerId=https://shibsles.brunel.ac.uk/idp/shibboleth" because the server where this page is located isn't responding."

Yesterday NFO authenticated okay for me.

regards,

Dom Benson

Thanks Alistair,

It's the same for us Mike.

So is it just "you and I" or are others having problems . . . . ?

I seem to remember something about IPV6 being a problem.

Hmmm, not my area of expertise, but I'm guessing this is something at their end?

I can't help but find it a little ironic that, following our Shib IdP upgrade, all our services are running smoothly and responding instantly except for these 2 which are operated by SDSS (AFAIK), one of whose roles is to help all of us to get our systems up and running properly ;-).

Anyone on the list responsible for these services able to comment? It looks to me like the delay is at your end - is that the case? Anything I can do at my end to fix it? It would be good if we could get these services responding in a timely fashion :)

Cheers,

Mike

Hi folks,

Here's one of those "is it just me?" questions/issues . . .

Following our recent upgrade to Shib 2, I'm tweaking/testing all our links to Shib protected resources. I've noticed an issue with access to NewsFilm Online and Statistical Accounts of Scotland.

Using the SP supplied WAYFless URLs, which for us are:

https://sp.edina.ac.uk/nfo/Shibboleth.sso/WAYF/UKFederation?providerId=https://idp.shibboleth.stir.ac.uk/shibboleth
https://target.sdss.ac.uk/statacc/Shibboleth.sso/WAYF/UKFederation?providerId=https://idp.shibboleth.stir.ac.uk/shibboleth

- these work, but seem to take "forever" to get access - I just timed trying to access NFO via the first link and it was nearly 90 seconds before I got redirected back to our IdP. Access to SAS is almost as bad, with it taking 75 seconds before I was redirected back to our IdP. These kinds of delays generally suggest something, somewhere waiting for something to happen, that isn't - so everything just hangs until the wait "times out" .

I've tried this from a couple of different machines, using a variety of browsers, with the same results .

I don't know if these sites usually take this long to respond as I don't use the services myself (my role in all this is just to keep the IdP running!) - I also don't know if these slow responses are a consequence of our recent upgrade or not. I've certainly not received complaints from library staff or students relating to these resources in the past, but that doesn't mean there hasn't been a problem! And 95% of our resources are now running via our Shib 2 IdP without issues.

So, just wondering what other's experiences of Shibboleth access to these services is? Is it just me, or are others experiencing some kind of timeout issue with these SPs?

Cheers,

Mike
