REMINDER: Upcoming meeting

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everybody, There is a WLUG meeting coming up on Wednesday, April 20th, at 7:00 PM in the Access Grid room on the WPI campus in Worcester, MA USA. This meeting is open to anybody with an interest in Linux. I'm still looking for a speaker for this meeting. If you are interested in volunteering, please contact me ASAP. If we don't have a speaker, we'll have to find a way to amuse ourselves. :-) Volunteer speakers get free food after the meeting. I recently received a large package from the Netherlands. It contains 100 Ubuntu Linux CD sets (version 4.10 from November 2004) to give away. Bring home 5 - 10 of them for your friends - I'm not kidding! Check out http://www.ubuntulinux.org for more information. Each set contains 2 CDs - one is a live eval CD similar to Knoppix, while the other one is used to install Ubuntu on your system. Feel free to stop in just to get some CDs (but I hope you'll stay for the meeting!). Ubuntu is Debian based with Gnome as the default desktop. I'll also bring two books for the free raffle: Sendmail Milters by Bryan Costales and Marcia Flynt Published by Addison Wesley PHPH-Nuke Garage by Don Jones Published by Prentice Hall Well, that's about it. I'm hoping we get a speaker, and when we do, I'll send out an email to the group. See ya on Wednesday!

Re: A OpenSSH question. --> Solution

by joel d

Hi, First a hearty thank you to all that replied to my conundrum. Here is how I got past the problem of my (FreeBSD 5.3 Release) OpenSSH's "sshd" key errors, not loading at startup: 1) I had an incorrect line in /etc/rc.conf. One problem for me was an incorrect path to the program. The correct lines that mattered were: sshd_program=/usr/sbin/sshd sshd_enable="YES" 2) I also did not have correct keys generated for the sshd aplication. Based upon your helpful e-mails and the man pages I found the following worked just fine to create the SSHV2 dsa host key: ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key 3) Also, based upon recommendations I turned off DNS lookup by my sshd server in the /etc/ssh/sshd_config file. UseDNS no All is well here and my adventure helps someone else some day. Correcting these problems got my Putty and WinSCP connections down to around 2-3 seconds (from around 80-90 seconds). Thanks again for the excellent advice from WLUG, Joel Desrochers

Re: [Wlug] A OpenSSH question.

by John Stoffel

Joel, The sshd conf looks fine to my eye, but I'd try and bump up the loglevel in there and restart the daemon completely. Then look in the log file on startup and see what it says. It might give more details. Unfortunately, I'm leaving for the weekend soon, so I won't be able to help much for a while... Good luck! John

A OpenSSH question.

by joel d

Hi, I am running into a problem trying to setup OpenSSH 3.6.1 on FreeBSD 5.3 release. I am connecting via clients (both ssh on BSD and WinSCP on Windows). I know this is not a FreeBSD group, but I bet someone else has run into this problem on a Unix-like platform. When I test the server with "sshd -ddd", I get an error back from the server which reads: debug3: Not a RSA1 key file /etc/ssh/ssh_host_dsa_key I have tried creating the above server key many times with no apparent luck. The clients connect to the server but the connect time is way over 60 seconds so I am bummed out. I have looked on the OpenSSH site and googled for it but have not found a workable solution. Any ideas would be appreciated, Thank you, Joel
