Simple Java Question...
by Stephen Daukas March 3, 2003

March 3, 2003

Hey guys! I have a really short Java question for you... How does one make a system call from Java? I want to be able to run a Linux command as I would in C, e.g., System("command"); The idea behind this is that I'm writing an example Java program to install an application, for example Postfix, that I may want to use as an example for Students... Later! Steve

Re: [Wlug] ssh-dummy-shell for OpenSSH???
by Brian K. White Feb. 28, 2003

Feb. 28, 2003

I have sort-of got this by setting the shell to sftp-server. bizarre, I know, but it works, and a copy of /bin/true does not. in both the real and chroot'ed /etc/passwd's I set the shell to the full path to sftp-server, and sftp works, ssh does not. ssh actually connects and will sit there until you type something, but as soon as you type anything sftp-server says "what is this rubbish?" and promptly hangs up on you. I don't have any real shell, or any other binary besides sftp-server in my chroot tree, and even though users can upload their own, they cannot execute it because their shell is only sftp-server, which is not a shell and cannot execute anything. I hope it doesn't have any cases where it could execute any external program like ls (I know it doesn't need ls specifically, just as an example the way ftpd often uses a ls binary in the chroot path). otherwise a person might be able to upload a shell named <whatever sftp-server might exec> this is OpenSSH 3.5p1 with chroot patch, on SCO Open Server 5.0.6 ------------ Actually it does. I tried /bin/false and it fails to setup the ssh connection properly. I guess the shell will let sftp only run specific sftp commands, anything else causes it to exit. -----Original Message----- From: Scott Venier [mailto:scottven@umich.edu] Sent: Wednesday, January 30, 2002 10:58 AM To: wlug(a)mail.wlug.org Subject: Re: [Wlug] ssh-dummy-shell for OpenSSH??? does the ssh-dummy-shell have to actually do anything for sFTP to work, or does it just have to be in /etc/shells? If it just has to be in /etc/shells, /bin/false works. Been using that for years for (non-s)FTP-only accounts.

SPARC and modems...
by William Smith Feb. 24, 2003

Feb. 24, 2003

I have a SPARCstation 10 with RH 6.2 loaded. I am trying to get it configured as an Internet gateway, but the big hurdle I am trying to jump over right now is the modem communication. I have checked the PROM settings and they match what I am using minicom with: 57600-8N1. (I am trying to use minicom to debug serial connection with the modem.) When I send commands to the modem, I see the modem is getting information, but it doesn't look like the modem is responding. I don't see an OK reply, much less any other sign of life... The modem in question is a Zoom 56k (it is the one I usually use to connect to the 'Net with, and it has worked with Linux and my ISP flawlessly in the recent past). Once I get past this, then I can look at making sure PPP works (which I anticipate to be a relatively minor ordeal, since I have a pretty good idea what to do), and then firewall stuff. While I think of it, would anyone know of any distributions with more-recent SPARC support? I'd like to see 2.4.x kernels with iptable support, as well as more up-to-date tools, but seeing as this beastie is on the "slow" side, recompiling everything myself would be tantamount to torture.... 8( Any assistance would be greatly appreciated.

Non Linux mozilla issue
by Adam Keck Feb. 20, 2003

Feb. 20, 2003

Here at MW we are blessed with Solaris workstations in addition to Linux. On Solaris 8 we have been unable to get the binary version from mozilla.org to run. It dies silently trying to load gtk. I compiled and installed gtk from gtk.org to no avail. Anyone run into this? Have any hints?

I need to run some win apps
by Geoff Feb. 19, 2003

Feb. 19, 2003

Hi, I need to run a few windows applications on Linux. I was wondering if anyone has any suggestions. The programs are: Palm Desktop 4.1 Eudora 5.2 And a couple of programs to programs 2 different ham radios. As for the linux setup. We'll have to wait and see the answer - I'm doing a fresh install on a new computer (will there be an install feast anytime soon?). I'm thinking Mandrake.

Meeting over the Access Grid?
by Frank Sweetser Feb. 18, 2003

Feb. 18, 2003

As a few of you may already know, WPI has just recently installed an Access Grid Node. For those of you who have never heard of the Access Grid project, it's a completely immersive video conferencing system - like traditional videoconferencing, but arranged such that the technology portion becomes invisible, and you can converse with others as if they were in the same room. More details at http://www.accessgrid.org/ My idea was that if we could find a couple of remote sites with people who might be interested in joining us, we could have a meeting over the Access Grid. A list of other Access Grid sites is up at http://www-fp.mcs.anl.gov/fl/accessgrid/nodes.htm and includes BU at least. If anyone knows anyone else at any of these sites who would be interested, we can start seeing about scheduling the time needed in all of the spaces. -- Frank Sweetser fs at wpi.edu WPI Network Engineer

REMINDER: Upcoming LAN Party !!
by Andy Stewart Feb. 18, 2003

Feb. 18, 2003

HI Everybody, The next WLUG meeting will be held this coming Wednesday, February 19th, 2003 in a different location. The meeting room will be AK233 (Atwater Kent room 233). Please refer to the Wlug Meetings...Directions link for directions to this room. The building is right next to Salisbury Labs on the WPI campus. Please note the earlier start time of 6:00 PM ! At this meeting, we'll be having a LAN party ! This is WLUG's first LAN party so I'm curious to see what people bring. You'll need to bring your network gear (hubs, switches, cables) and a laptop or desktop machine with networking enabled. We'll interconnect all of the machines to create one big WLUG LAN. I'll bring my PLIP cable for the masochists in the crowd. This network most likely will *not* have access to the Internet (but we'll see what we can do). On this LAN, all sorts of activities could take place, such as multiplayer games, network security scans, attempts to (non-destructively!) crack another persons system to teach them about their security weaknesses, and more. Its really up to all of you and your imaginations as to what we can do with this type of setup. I'll even entertain doing a couple of network based Linux installations if folks want that. If people need help configuring their systems for networking, that help will be available. I'll also be available to do a demonstration of VNC for those interested. The possibilities are really endless. Due to the amount of time to setup such a LAN and still have time to have fun with it, I've extended the time of the WLUG meeting from 6:00 PM - 9:00 PM (note earlier start time!). Have a lot of fun, and I'll see you all on Wednesday. Andy -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA USA http://www.wlug.org
