Unexpected IGMP network traffic
I recently set up a RH 8.0 "home network" server. It's very much like several others that I've done before. Samba for a windows file and print servers. And, because this customer wanted to get a look at Linux, two VNC servers that are accessed by VNC viewers on the windows boxes. The customer is happy. All of this is behind a linksys firewall/router. So, the linux box has no firewall. I did try to shut down all unneeded services. But just for fun, I ran nmap and netwatch on the server. Nmap shows only the expected ports open. However, netwatch shows a lot of IGMP packets. These are returned by what looks like multicast servers on the internet. I shut down the windows boxes, stopped the VNC servers, and stopped samba. But the IGMP chatter continues. Seems like I've seen this traffic from windows. But, never from linux before. Does anybody know what I might have running that's creating all the chatter? Thanks, Cliff Kent -- Psyche-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/psyche-list

Re: Unexpected IGMP network traffic
>> Does your client use a fixed or a dynamic IP? << Internet connection is Adelphia cable modem. Dynamic IP via DHCP - though the actual IP address hasn't changed in a year. Cable modem connects to the private network through a Linksys cable/DSL router that SHOULD be blocking all such unrequested traffic. (I'll recheck the router config.) I have "nmap -sS -p 1-65535 -P0 w.x.y.z" running now from my office. It's going to take a while, but so far 7500 ports have gone unanswered. I'll run a UDP scan when this one is finished. I'm on the same cable provider. The same subnet in fact. My firewall is a single floppy two nic linux router project box. I get no such IGMP traffic here on the private net. Unless the router config is messed up, I'd say the IGMP is originating in linux. Thanks for you help. I hope to visit that machine today.

Re: Linux Slapper worm - New variants ?
Jason, >> ... possible Linux slapper worm activity on one of our Linux servers ... << I had slapper A on a web server briefly. So I'll pass along what little I know. I say briefly because a power outage had caused a server restart. When I got there to install the software updates, I had all the signs of slapper, but it wasn't running. I found these files on the server: /tmp/.uubugtraq /tmp/.bugtraq.c /tmp/.bugtraq and deleted them. But, the command: fuser -n udp 2002 did not find a process on the slapper a port; apparently the result of the power outage. I now routinely use: nmap -sU -p 1-65355 -P0 xxx.xxx.xxx.xxx and nmap -p 1-65355 -P0 xxx.xxx.xxx.xxx to look for incorrectly open ports. And I use netwatch to look at traffic in real time. What I see recently is very little UDP 2002 activity, but fairly regular UDP 1812 traffic. Netwatch also shows me that my server is not replying to these packets.

Re: accessing the rdh8.0 desktop via ssh
Craig, Sorry, I can't answer your question about configuring the vncserver. I did make it work a while back (7.2 maybe ?) but ran into trouble when I went back to the physical console. It seemed to me, without doing any research, that if the local X session is display 0 and there is a vncserver for the same user, in the same home directory, on display 5... well strange things might happen. So, I went back to "the old way": Each user has two scripts in their home directory, vnc-on and vnc-off. For example: #!/bin/sh # vnc-on vncserver :5 -geometry 1152x864 -depth 24 #!/bin/sh # vnc-off vncserver -kill :5 On my small network, I hand assign the display numbers. Then, to make my vncserver start at boot time, I add the following to /etc/rc.d/rc.local: su -l cliff -c ./vnc-on All my machines boot to run level 3. Among other benefits, this lets me run ./vnc-off before I startx on the console. In practice, I also have a selection of "vnc-on" scripts with different geometry and depth settings for when I want access from a machine with less video hardware or bandwidth.

It seems that if I install both desktops and the applications for both on my rh8 workstation, I'm able to pick the applications I prefer on either desktop. I don't expect them all to work, but I'm pleased with what does work. For example galeon, gftp, gnome-system-monitor.desktop, and gnorpm (from rh 7.3) all have been solid with KDE. I've also used konqueror (as a file manager) and (I think) quanta too under gnome2. My customers seem happy with gnome2. But, I switched back to KDE after about two days with gnome2.
