Very comfortable with the commonly used options in network troubleshooting such as interface, protocol/port, packet type, host, monitoring, etc. Which is a reflection of how I've used it as a Network Engineer. Troubleshooting client/server software communication would take some time reading and tinkering. The far more difficult thing with tcpdump is being able to make sense of the output. ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Re: [PLUG] Nothing on monitors
Great way of using nmap.
This way you can also see the IPs and machine name together with open ssh
ports:
sudo nmap -p 22 192.168.1.2- | awk '/Nmap scan report for / { hostLine=$0;
hostLinePrinted=0; } /open / && hostLinePrinted==0 { print ""; print
hostLine; print $0; hostLinePrinted=1; next} /open / && hostLinePrinted==1 {
print $0;}'

This is the obstacle to using SMB on Linux as I see it. If you put the password to a file and protect it, then there is no user separation/access control as all the files on the SMB share will be owned by single user. If you figure out a way around mount for a user, and you have two different users trying to mount the same thing using different users - then you are toast too. If a user forgets to umount then you need root intervention too. I do not want to sound negative about usefulness of SMB on Linux - I was really hoped that someone knows how to make it work as per Unix/Linux. :-) Anyway, let's not hijack this post to SMB bashing. > ___ > PLUG mailing list > PLUG@lists.pdxlinux.org > http://lists.pdxlinux.org/mailman/listinfo/plug ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
