Trying to solve an access problem

Post #155,405 by dmarker 5/16/04 6:33:40 PM 5/17/04 12:22:32 AM Reply	Trying to solve an access problem (#2 - just was advised that the forum server part of their website is actually in Germany, only the main website is hosted in the US - probably doesn't change the problem much) I have been actively accessing the below website while participating in the beta of a new product (some will recognise it from earlier input I was given in this forum). The product is ZOC & the company EmTec is based in Germany but their server is hosted in US. I have no problems accessing www.Emtec.com but can not always get through to www.emtec.com:8000/index.php The details are a tad complex so I will try to put this as simply as I can. 1) My company notebook has been the prime conduit to the above named link and has been working ok but increasingly I began to get the below message whilst accessing this link from work...... ************************************************* ERROR The requested URL could not be retrieved -------------------------------------------------------------------------------- While trying to retrieve the URL: [link\|http://forum.emtec.com:8000/index.php\|http://forum.emtec.com:8000/index.php] The following error was encountered: Connection Failed The system returned: (111) Connection refused The remote host or network may be down. Please try the request again. Your cache administrator is webmaster. -------------------------------------------------------------------------------- Generated Mon, 17 May 2004 18:03:34 GMT by davdmz1.davids.com.au (Squid/2.4.STABLE2) *********************************************************** 2) So I then tried using my collection of home computers, on a new ISP, to access the above link. I am consistently getting similar connection refused message. I have changed my router to permit IDENT requests plus any others but that makes no difference. 3) So the picture at this point is that from work I can very occasionally get through nodays whereas 1 month ago I was regularly reaching their site 4) Now come the bit I don't understand.... IF I take my work notebook home & connect to my home LAN then access the above link, it works almost evert time ??? - but if I still try to access this link from my other home computers, on this same LAN, they all fail ??? 5) At the moment, the only way I now seem able to access the emtec:8000 port is by taking my work notebook home & using it on my home LAN. If anyone can take a guess or suggest other techniques to pinpoint possible causes at what might be causing this I would be grateful as I can't see why this should occur. The frustration is at not being easily able to read or post items at this site at a time I am doing a major conversion involving ZOC software.

Post #155,414 by dmarker 5/16/04 7:45:08 PM Reply	Asked the manager but was told none else is reporting any problems like that - just you :-) They do have mail-marshall in operation & we have two proxy servers. I have tried both. The connection-refused part of it looks like a classic IDENT request failure. That I could understand as I am sure our Sidewinder / PIX firewall config, will block IDENT somewhere. The situation at home mystifies me. One last test I will try shortly, is to remove my LAN & router & do a direct connect to ISP & see if my home server will get through then. But why would my work PC fail to get thru at work but work fine at home at the same time as my home servers won't get thru, they all go thru the same NAT firewall router ??? Doug
Post #155,418 by dmarker 5/16/04 9:00:56 PM Reply	Just eliminated home router as the block This one of my servers is directly connected to big pond ISP and in addition I shutdown ZoneAlarm Pro on this machine. All I get is a timeout (rather than the connection refused message). Doug

ZOC will be a nice enhancement to ZOC 4 Tks Doug

Post #155,442 by dmarker 5/17/04 7:27:15 AM Reply	Again thanks - hmmm seems that their website isn't in US I will ask Marcus Schmidt again tomorrow. Perhaps he meant that their delivery servers (for ZOC) is in US. Thanks muchly for the tests from UK. Doug
Post #155,440 by dmarker 5/17/04 3:45:23 AM Reply	Alex, just to eliminate all doubt, were these to the full .. link of www.emtec.com:8000/index.php (rather than just www.emtec.com ?) Just want to be completely clear on the results. Thanks Doug

But, originally you had: [link\|http://forum.emtec.com:8000/index.php\|http://forum.emtec.com:8000/index.php] Now, you don't have 'forum.' prefix.

Post #155,587 by dmarker 5/17/04 6:03:37 PM 5/17/04 6:35:29 PM Reply	OOOOPS ! - will check that again I fucked up ! On my work notebook the link was emailed to me & I clicked it then saved the link. On my home computers I enetered the web url then the port etc: My appologies for asking you to partake in this little 'dance' I still have the problem at work but I think Box was right re our firewall which was upgraded after sasser & that was when I stopped getting emtec forum access. Doug #2 PS - I was just in contact with Marcus Schmidt the author of ZOC & moderator of the forum & even he missed the www -> forum subtlety so I don't feel quite so stupid about my cock-up in transcription :-) Edited by dmarker May 17, 2004, 06:35:29 PM EDT Expand All History
