DNS and PPP

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, I have a setup like this: palmtx -> computer --> firewall/dns_server The connection between the palmtx and the computer is a PPP connection (ppp0) over bluetooth, which works fine between the palmtx and the computer. The connection between the computer and the firewall is ethernet (eth0), and it also works fine. My problem is that I can't get the palmtx to get dns responses back from the dns server. I ran ethereal on eth0 and ppp0. I can see the DNS query go from the palmtx to the computer, and out to the firewall on eth0. The firewall responds onto eth0, but the computer doesn't seem to be sending that back to the palmtx on ppp0. On the computer, routing is enabled (or the dns server wouldn't have seen the initial request). The route table has the entry (1st in the list) for the PPP connection. iptables is set to accept everything. What did I miss? Thanks!

Re: [Wlug] FUSE??

by freak4uxxx＠gmail.com

>From what I understand, fuse is the lower layer of filesystems such as captive ntfs and shfs. Captive ntfs uses the win32 drivers for ntfs via user space to allow you to write to an ntfs partition. Shfs is one of a few remote via ssh file systems. -Eric -----Original Message----- From: ken jones <kjones(a)ziplink.net> Subj: [Wlug] FUSE?? Date: Sat Aug 12, 2006 11:03 pm Size: 907 bytes To: WLUG Mailing list <wlug(a)mail.wlug.org> Would somebody please explain to me what exactly FUSE does? I succeeded in using fusexmp to mount my root directory into /tmp/fuse2.5.3/example. I also succeeded in unmounting with fusermount -u. I do not understand why I should want to. This all started when I upgraded the kernel and the type ntfs file system on the other half of my dual mounted system refused to "mount". I got distracted into FUSE then remembered to install the matching kernel-module-ntfs below. Now I am again successfully using 'smbmount' to mount ntfs file types. I am running Fedora 2.6.17-1.2142_FC4 with kernel-module-ntfs-2.6.17-1.2142_FC4-2.1.27-0.rr.10.4.i686.rpm What good is FUSE to me? I've Googled till the cows come home, but I do not understand the responses.

Gentoo leaves it open by default (for better or worse) $ ls -l $(which fusermount) -rws--x--x 1 root root 18848 May 9 16:46 /usr/bin/fusermount My /bin/mount has the same perms, btw. -Jamie

Help! And there's the rub with FUSE. You need a setuid-root helper to perform the actual mount. Check the permissions on /usr/bin/fusermount. On my system, they've set it up for setuid-root but Fedora has deemed this to be enough of a security risk that you have to be in the fuse group to run it: -rwsr-xr-- 1 root fuse 22512 May 3 09:49 /usr/bin/fusermount
