Re: [Alug] Rs-232 and terminal servers
by Ricardo Campos 03 Jan '03

03 Jan '03

First off: thanks for the replies! Wow! ALUG'ers do it again! :) Second: I'm investigating this problem for a uni project (for my MSc), so I guess the ALUG archives are going into my bibliography! ;) so, umm... these units are *fictional* lol, sorry! :) Third: I kinda thought on scrapping the RS-232 thing, since I'm fairly comfortable with ethernet and TCP/IP, but since these units have rs-232 (and they were duly mentioned by my tutors) I thought "maybe there's a reason ppl still linger with it". My first idea was to have two ipcop (www.ipcop.org) servers(firewalls) at either end of the connection to sort out a vpn over the POTS. Luckily we are dealing with temperature ranges of 5-30, so there's no real safety issue that can't wait the time it takes to dial up! Fourth: 'tis my job to write the programs to handle this, so that's all cool. Well... of to do some planning and decide whether SSH tunnels or a VPN would be better in this case. Thanks! Ricardo

Rs-232 and terminal servers
by N3tw0rkAng31B0y 03 Jan '03

03 Jan '03

I'm investigating a solution. Basically I have a unit that must be remotely monitored. The unit itself has an rs-232 connection and ethernet too. However, for the tiny amount of data transfer needed (it sends temperatures), the rs-232 should suffice. I was thinking that I could attach this device to some sort of terminal server and then attach the server to the internet via a free dial-up, or perhaps a 64k leased line (it needs to be constantly monitored). Has anyone done such a thing? If so, any tips as to what to use as a terminal server? I realise this might be old hat to the rest of you, but I have no experience of this! TIA Ricardo

Hi, I've just joined the mailing list. I've worked in the I.T. industry for a number of years as a programmer, designer etc. I'm currently using IBM's Websphere MQ with Java and am very interested in the concept of open source ( why give money to Bill Gates et al if you don't have to ? ) As Linux is the most popular open source OS, I thought it was about time that I learnt something about it. I look forward to participating in the group.

Re: main digest, Vol 1 #527 - 7 msgs

The other possibility is that you have to set a jumper on the motherboard to let the bios know that the memory is there. I remember struggling with this years ago, and then noticing just beside the SIMM socket there was a jumper to set the memory size.

over-riding BIOS memory detection
by Glen Tyler 30 Dec '02

30 Dec '02

Dear All, can anyone help/put me straight on this. I have a i486 machine running Slackware 8.1. As a christmas present I bought it a 32MB Simm, it currently has 16MB installed (one module). When I replaced the 16MB with the 32MB the bios still only detects 16MB on boot and everything runs as before. No matter I thought - I have read somewhere that Linux will override such settings, but I have been unable to get the kernel (2.4.18) to do so. I read the lilo.conf man page which indicated that adding 'append="mem=32M"' to lilo would do it, but the computer would not boot after adding this. A further search of the internet produced a sort of How-to doc that lists three options (but I think is written for RedHat). The first of these is the same as the lilo.conf recommendation, the second involves giving mem sizes and start locations in hexadecimals e.g. append="mem=exactmap mem=0x9f000@0 mem=0x1f00000@100000" and the third is like the 2nd, but in english.. append="mem=exactmap mem#=640K@0 mem=31M@1M" all these end in the same result - failure to boot. I have tried these messages specifying 16MB as the memory size (incase there really was a problem with the 32MB size) but the result is the same. In the mini how-to it is suggested that white space is needed between the start quotes and the first mem statement - but that doesn't resolve this problem either. So - am I correct in assuming that the Linux kernel can use this additional 16MB of memory , and if so how do I let it know its there? all the best Glen

Phoenix Homepage
by Wayne Stallwood 28 Dec '02

28 Dec '02

Ok so I may have a slight hangover, and thus not really firing on all cylinders. But this is driving me mad. I have Phoenix 0.5 installed. it's working really well for me apart from this one annoying problem. Regardless of what I set as the homepage Phoenix always starts by displaying http://www.barnesandnoble.com/. If I click the home button Phoenix will go to my configured homepage. and when starting up you can see it starting to load it in the status bar at the bottom of the window before going to barnesandnoble. I've greped both my .phoenix/ directory and the installation directory for the URL. found nothing. Done a google search and looked theough the Moz docs all to no avail Any ideas anyone before I start downloading the source and looking through that ? Wayne
