Title: DNS problem?
Post by: Weaver on March 08, 2021, 10:58:03 AM
I’m trying to access the web server www2.smo.uhi.ac.uk and it seems to me that its DNS has gone bad in some way. I used an iOS DNS lookup app and I got a ‘timeout error trying to access DNS servers’. Looking up something like www.google.co.uk worked fine so it’s not a problem at my end.

Anyone got any thoughts?

It’s the Gaelic college on Skye, affiliated to the UHI (University of the Highlands and Islands) and I’m surprised if they have managed to break their DNS. Very odd.

It's not a DNS problem, the server is down. You can check with https://www.isitdownrightnow.com/ (https://www.isitdownrightnow.com/www2.smo.uhi.ac.uk.html) or https://downforeveryoneorjustme.com/ (https://downforeveryoneorjustme.com/)

Ah, many thanks! I forgot about those useful sites. The app I used seems to give out misleading error messages then.

Wow, SMO (the college, www.smo.uhi.ac.uk) has broken their Gaelic dictionary web server. And their main one www.smo.uhi.ac.uk according to that testing tool website. What on earth are they doing?

It has been down for days now. How can the entire college www be broken for this long? Any thoughts ?

A traceroute just goes off into oblivion in or after JANET.

I'm amused that the Japanese database was used for both of the above lookups.

@jelv I saw that ‘main university’ site. SMO is a semi-autonomous thing with its own governance and is just affiliated with the UHI. That UHI website is in English whereas SMO’s own website is all bilingual with Gaelic being the default, and also has a separate sub-site containing very useful stuff meant for current students. SMO also had a second domain name www2.smo.uhi.ac.uk which is used by their web-based Gaelic-English dictionary service.

It’s incredible - how they can just let it break? Perhaps their domain registration ran out because someone screwed up?

My neighbour works for the UHI at SMO, so I will put my wife on the case.  ;)

I don’t think ja.net has anything to do with Japan - it’s the Joint Academic NETwork (JANET), which has been around in the UK for yonks.

Thank you, both.  :)  I'm well aware of JANET, from the 1980s, but wonder why such an obscure reference is used?  :-\

My wife tells me that UHI as well as Sabhal Mór Ostaig (www.smo.uhi.ac.uk) has been hit by ransomware but I don’t have any details; on Saturday last. She said various other organisations have been hit.
Title: Re: DNS problem?
Post by: Weaver on March 25, 2021, 04:58:09 PM
I simply can’t understand why the servers have been down for so long. We’re they not backed up? I would just wipe them and restore from a backup. I always used o keep a complete bootable cloned full system on a hard disk in a drawer ready to just drop in, so a restore wasn’t even needed. (I used Acronis full drive cloning s/w back then.)

Having just checked, I can type "likewise".
Title: Re: DNS problem?
Post by: jelv on March 25, 2021, 11:21:03 PM
Works for me as well and I couldn't access the other day. I suspect you are looking at some sort of cached result (either DNS or the failed web page itself).

I’ve just realised that I get nothing if I try connecting to that server on port 443, but on port 80, I get the usual response. This is the port 80 response:

So you are now able to see the web-site?  :-\

I guess they figure there is no need for https, a little odd by todays standards as its meant to be a faster protocol these days.
Title: Re: DNS problem?
Post by: Weaver on March 28, 2021, 12:13:14 AM
No, I still can’t see the site. Safari insists on going to https even though I manually correct the URL to http://. It was working with TLS only a month or so back. Very odd.

Obvious question: have you tried a different browser?
Title: Re: DNS problem?
Post by: tubaman on March 28, 2021, 09:19:58 AM
It's working fine here on Chrome (via Win10) and Firefox (via Linux).
As others have said it doesn't respond to pings.
Title: Re: DNS problem?
Post by: atkinsong on March 28, 2021, 10:22:09 AM
Working here with Safari on both iPad and Mac.
Title: Re: DNS problem?
Post by: Alex Atkin UK on March 28, 2021, 02:33:58 PM
Chrome and Firefox, there is no https redirect thus it loads fine.  Although it may be some browser versions are enforcing https anywhere in some form which would obviously be a problem.
Title: Re: DNS problem?
Post by: Weaver on March 28, 2021, 10:30:12 PM
I tried the iCab browser on the iPad instead of Chrome, and this works. I’m wondering if there might be something unhelpful in there.
Title: Re: DNS problem?
Post by: Weaver on March 29, 2021, 04:52:47 AM
I tried Chrome and Firefox on the iPad. Not sure how similar the code is in these iOS/iPadOS builds to that that we are used to on a Mac or Windows box. Got the page at www.smo.ac.uk to open, but one of my favourite URLs (Scottish Gaelic dictionary) is at:
     https://www2.smo.uhi.ac.uk/gaidhlig/faclair/sbg/lorg.php
and that just hangs, still, even in these other browsers just like Safari/iOS. So all iis far from well.

That page does appear to hang at present. There's another online dictionary at http://www.dwelly.info/ (link taken from http://www.smo.uhi.ac.uk/en/colaiste/gaidhlig/ceanglaichean-feumail/)
 :)
Title: Re: DNS problem?
Post by: Alex Atkin UK on March 29, 2021, 08:22:17 AM
That DOES seem to try to redirect to https which is why its not working.  They really need to fix their server configuration.
Title: Re: DNS problem?
Post by: Weaver on March 29, 2021, 06:07:14 PM
Thanks tubaman; I always use both as the set of english words is better in the Stòr-Dàta, but the dwelly.info dictionary is the stunning reference, the bible, if you like, best for detail. And of course, I can’t follow that link (http://www.smo.uhi.ac.uk/en/colaiste/gaidhlig/ceanglaichean-feumail/) in Safari, but it doesn’t matter as I know the dwelly.info website well already.

I’ll ask my neighbour, who works for the UHI and let him know what’s going on.

I only managed to regain my sanity when I used the NET-Toolbox app for the iPad with its HTTP-Head analysis tool which shows you the straight payload of response packets when making requests to either port 443 or port 80.

Thank god, they’ve finally fixed the web server configuration. My complaint got passed through to the right people, it seems.
