Hi Moritz,

Try http://www.os2site.com/, ie, it needs the www in front :)

If you install an email server program such as Weasel from Peter Moylan, you can setup it up so email that comes in for one user is automatically copied to several other users [by extension, to, or from several users]. ie, its all to do with creating one or more alias's which still have seperate mailbox's.

You can then have each computer have its own user (mine1@, mine2@) which are all receive alias's for your primary email address(s). As each computer access's that account, then it deletes email after retrieve from that computers POP email account. This allows each computer to retrieve all the email sent to that one user with no double ups across different computers. When any of the computers send email out, they can do so via Weasel or via your external SMTP server using the email address(s) that you wish the outside world to reply to.

Hope that makes sense. Probably best described with a piece of paper and a pen to make a flow chart :)

Have internet access again with a permant IP but it is slower than our current 3G access, probably due to the lockdown and everyone trying to work from home as we are on a HFC segment with 97 connections. I will move DNS around after my Wednesday exam and turn the server back on, Wednesday is a window that might be as long as Friday, I'm still trying to get Zoom working for Uni (cant get past the capture under Linux or Windows), do the shopping and study while feeling old all at the same time.

I think once one or more mirrors are organised, my server will be purely email and rsync replication. It's all getting to hard :(

For university class's, I gave up and used Powerpoint.
Everything else I looked at involved more time and messing around :(

I thought about Libre Office to see if it had an export to 'video file' function but as others were already using Powerpoint I um, gave up.

I did a quick search and found https://extensions.openoffice.org/en/project/impress-video-converter but only for Windows, Linux

Hi All,

Yes, I'm having internet problems, as in none :(
It is looking like it will not be up for a while as I suspect the wholesaler of australian HFC service will nolonger attend site due to social distancing. I'm not qualified to replace a NTD (HFC modem) apparently :o)

Roderick has offered to host the website and I have sent him an SSD - the hosting will be without the need for authentication for site access.

If anyone else is interested I can be reached at ian at os2site dot com <== moved email to a hosting provider.
Hope you all keep well.

Hi Dave,

Makes sense but I was seeing problems from day 1 on two Western Digital Blue 500G SSD's, and one Western Digital Blue 1T SSD.
I suspect my problem was due to the double caching that was happening on both my server and my OS/2 primary computer.

RAM drive now stores everything that I do not mind is lost on the server, or is transient, including log files from InJoy FW etc that I really don't need but look at occasionally anyway. What I've done since is to move all data manipulation to the RAM drive (about 500MB in size) for a nightly stats run. The server is really only used for os2site.com and my personal email now so the only logs that grow on the SSD are Apache (http) and Weasel (mail).  SYSLOG etc are all transient.

To overcome any possible problems I have been backing up more regularly but expect to copy the drive(s) to a new one occasionally but I don't intend to do that for at least 6 months, if ever, depending on what my results are going forward and if there is really a need to TRIM these drives.
The SSD's have been to me, an experiment in power consumption, noise, heating, and speed - though on the internet side there is no difference, on the network inside there is a big difference.

PS..
The server now only uses 43.183 MiB or RAM :-))

What do you think about my idea of an historical section on hobbes as the repository for such items?  That way it would make the older items easier to find.

That would have its own set of problems as it would require a lot more manual intervention. In saying that, what I have done with os2site.com is to add a subdirectory for old/replaced files.

The main aim of this post however is to let you know that hobbes is being looked at and changes being made.

A web interface for file uploads but still retaining FTP access for uploads/downloads
Looking at a recycle/replaced files area
Add files from incoming to the main file areas at time of upload, this means the files will be added to the database immediately (for searches etc).


I have also mentioned the banned IP's.

Re hobbes mirrors

http://www.os2site.com/mirrors/hobbes.nmsu.edu/ It does require a valid UA browser string or user access but that will change soon as I'm ready to send off os2site.com contents to somewhere that will not require user authentication to access the website. [added: the hobbes mirror at os2site.com is mirrored whenever hobbes incoming directory is cleared]

os2site's incoming directory which does not require user authentication always mirrors hobbes incoming within the time differences, ie, os2site.com's /incoming contents are moved to /new at the end of every month.

After much experimenting since the start of November since I moved to SSD's.

Turn JFS Lazywrite OFF if using an SSD.

There is minimal performance difference on an SSD, and it has been almost 3 months since I have had the odd weird file corruption.
The files that were corrupting on me were due to scripts that would copy, delete, process log files, sometimes the end of the files would be full of nul information as if I had deleted the file to be appended to another before the information could be written to the new file.

Hi Tom,

Conclusion: /pub/incoming seems to be excluded from the search , even when /pub/incoming is passed as the searchpath.

That is correct, with people occasionally uploading php, scr, jpg, iso and other non hobbes related files (sometimes copyright protected programs), incoming is on purpose excluded from hobbes internal and external search results. Incoming content is deemed to be of a transient nature.

The majority of people automatically check the incoming directory for the latest files already so it would have been viewed as very minor not to have the contents indexed in the search database.

My websites /incoming and /new directories are also excluded from search indexing but that is because the directories are automatically cleared at the end of every month so the content is transient and should not be included in search engine index's.

Hi Martin,

Will add it to my list :)
It should be possible to alias h-search.php so both URL's will work, I actually thought that Curtis had already done that but it must have been for only incoming.

Hi Valery,

Nothing personal against any country in particular but some countries do have a habit of allowing people access to whole 255.255.255.0 ranges or bigger and being very slow to act when those ranges are abused :(  as to hackers, Russian or otherwise is irrelevant (real hackers would be using bounce services from Romania, VietNam or other country's anyway - just saying), its the bored kiddie scripter's that do more damage to services like Hobbes especially as it has free access to upload files. ISP's have driven down the price of access that they themselves often are no longer interested in abuse reports unless it affects them, which is why so many people block entire ranges, even the entire ranges of one ISP (OVH France was a regular early 2010's).

Policing the upload directory at Hobbes takes time and is dependent on volunteers as there is only one person at nmsu.edu that looks after it, and it is but one of many things on his plate.

I've blacklisted ranges of IP's in Eastern bloc countries in the past but I have also blacklisted ranges from USA, France, Canada, China, Malaysia,  Italy, Germany, Seychelles etc. ISP's with new staff are often either far to 'innocent', or the ISP's are happy to take the money while they can get away with it. USA is the largest representive country in my email RBL's at present as they "do not take heed of spam reports unless they are from customers" Amazon are the worse with moving reporting goalposts, followed by sendgrid.net with allowing spammers easy access and claiming that I need to complain to MY upstream ISP, not to them. Both of those companies use ranges scattered all over the place, and are happy to move customers around. Even Microsoft and Google are now only concerned about abuse if it affects their customers, unless it is something large scale that might attract media attention.

It is the resources needed to police services and maintain adherence to a countries laws that so many different 'free' services have given up as it gives no return on effort. I do not want to see Hobbes go in the same direction.

I will see if it is easy to get an IP banned list from hobbes and what we can do to address any access problems to do with those banned IP's. Not promising anything as I'm not Hobbes but if I offer to do the work for them it maybe more likely to happen. I can see what IP address that you and others are posting from so that gives me something to use in checking if I can get access to the list.

The Hobbes server is a different machine to nmsu.edu.

Hi Everyone,

Curtis, the 'maintainer' of hobbes is busy with another project at present, I've thrown some ideas about how to present the text information description files, and access, to him but I can not see anything happening for a 'while' on that front.

I will let him know about the access issues though I suspect they maybe to do with IP ranges being added to the blacklist for uploading scr, php, ISO and other irrelevant files, I've had similar issues with form and DoS attacks from Russia and Ukraine but now most of my banned ranges are China, VietNam and USA so Curtis maybe amicable to relaxing access blacklists when he has time. Hobbes is on a new server, and I know that Curtis has been looking at different ways to secure the server while still giving access to those who use it.

I'll come back to this thread in a couple of weeks time and gather all the information up and let him know.

For those who would rather not go through me, the new Hobbes Archiver email address on the Hobbes server does work (hobbesarchiver at nmsu dot edu) fine for me from Western Australia, so problems could be due to blacklisting or routing issues. I say routing issues because I've been having intermittent packet problems to Europe for the past 3-4 weeks with no access to China.

As pointed out by Wim, you can access the directory directly via https://hobbes.nmsu.edu/download/pub/incoming/
or FTP via ftp://hobbes.nmsu.edu/pub/incoming/  using anonymous, and your email address (fake or real) as the password.

Hi Massimo.

goto https://www.speedguide.net/analyzer.php

What does it say your "RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)" is?

and what value does it give for "Unscaled TCP Receive Window"?

What you are looking for is a MULTIPLE that fits, the size of RWIN is not overly important for us. Ignore the bandwidth * delay product for now. If you are interested you can find more information on that by searching for  RFC1323 and having a read.

Hi Andy,

I used Wireshark.

I'm having a look at whats available via a link way up above at https://www.speedguide.net/analyzer.php
The links given under "Optimize Your Connection" seem to be quite good.

https://www.speedguide.net/articles/the-tcp-window-latency-and-the-bandwidth-delay-2678 is a good summary.

I will also throw in https://www.ibm.com/support/knowledgecenter/ssw_aix_72/performance/tcp_workload_tuning.html for more information though much of it is not relevant to OS/2.

There is a Windows based optimiser available here: https://www.speedguide.net/downloads.php
I have not tried this one but the rest of the information they give seems good so worth a try. I originally tried Wireshark under Windows 10, gave up and used Windows 7 were I got some good results.
