Looking for dial-up provider (Westboro area)
by Stephen C. Daukas April 3, 2002

April 3, 2002

A friend of mine has a small business in Westborough and I helped put together a web site for him. He now wants to dump AOL and get a less expensive "dial-up account". Anyone have a recommendation? He is paying ~$25/month for AOL... He doesn't want/need Charter, just wants to check mail a few times during the day. Also, anyone know if you can set-up email forwarding in AOL? Thanks! Steve

Problems dropping telnet sessions
by Simoncini, Matthew April 2, 2002

April 2, 2002

Hello all, I recently traded in my Solaris 8 (x86) install for SuSE Linux 7.3 and now am having problems keeping telnet sessions open for extended periods of time. Let me give a little background on what I use this box for. Basically my linux box is used as a workstation for system monitoring. I usually have 6 to 8 separate desktops which I use to separate our different Unix environments (i.e. development, test, production ...). I may run HP Openview client on one desktop to monitor alerts and keep telnet sessions open on other desktops in order to quickly access a given server. Until recently I've been using Solaris 8 (x86) with no problems, but decided I wanted to get comfortable with linux and prove to my boss that there are many nice things we can do with linux that we can't do with Solaris. I installed SuSe 7.3 (2.4.10 kernel) and since have had troubles keeping telnet connections alive. What I mean by that is, when I leave the linux workstation inactive for a period of time (let's say 30 minutes), my telnet sessions are disconnected with the message "Connection closed by foreign host". I can find no messages in /var/adm/messages (on the Solaris side) or /var/log/messages (on the linux side). Anyone have this type of problem or more importantly, can someone point me in the right direction? Thanks. Matthew

poor PCMCIA network performance
by Robert L Krawitz April 2, 2002

April 2, 2002

I use two network cards in my Dell Inspiron 8000 (PIII-700): a 3Com 3CCFE574BT and a Linksys wireless card. With the 3Com card (which is a 10/100) I never get better than 1.4 MB/sec (about 12 Mb/sec), even when the card is in 100 Mb mode (at some point in the past the limit was about 2.5 MB/sec). At that rate, top shows my CPU utilization pegged at about 100%, even doing a simple ftp. I know the card doesn't do DMA, but that's rather slow even for a PIO transfer. These cards have been around for ages; I don't think people would have been too satisfied with 400 KB/sec saturating a 200 MHz system. On the Linksys card, I likewise never get more than about 250 KB/sec, even if the computer is right next to the WAP and the link quality is 92/92, suggesting that I'm also hitting up against a hard limit. The WAP is connected to my main system via the motherboard ethernet, which I know from other means (when I was transferring data from my previous system to the current one) has no trouble maxing out at 10 MB/sec (that ethernet does DMA). eth1 IEEE 802.11-DS ESSID:"..."
