It looks like the traffic goes trough "lo" instead of ethernet device !
[root@f16asx ~]# tcpdump -n -i lo port 6543
Show it as expected !
This has changed ! Maybe kernel 3.1 ?

Connection closed by foreign host.
If I do the same from another host on the local network or if I try to
connect to another host or if I use "lo" the loopback and 127.0.0.1
instead , I can see the traffic !
It look like pcap don't want to capture packet that stay inside the
the host, except for "lo".
I have no FW rules and SELinux is disabled !
Any idea ?

Install it on the 3 computers and run it : - as a server at home, to get connection from the the client and console - as the client at work, to open and keep the the connection open with home - as a console on your laptop at the hotel to activate a tunnel and connect through SSH or directly on port "3389" to another computer inside the company. http://blog.magiksys.net/software/tcp-proxy-reflector Have fun > > Regards, > > Leland C.

"echo hello > /dev/pts/2" is blocking
I have a FUSE program in debug mode displaying a lot of debug messages on the terminal. After hours the program "freeze" and the terminal looks blocked. The terminal don't react to key press, nor CTRL-C nor CTRL-Z Using gdb, I get 31 threads, the 25 looks strange. It looks to be blocking on a write() system call while displaying a debug message to the terminal Then I tried # echo hello > /dev/pts/2 and it's blocking too ! Other pts on the same host don't block How can a pts block ? Probably a problem with ssh or sshd. Using strace, I can see both waiting on a select() and not reacting to a key press or to the echo hello > /dev/pts/2. The ssh client is running on a fedora 11 What next ? I'm running fedora 14 on x64, but get exactly the same on a f14 i386. I'm running the same test on centos-6 x64 just now Regards -- Alain Spineux | aspineux gmail com Monitor your iT & Backups | http://www.magikmon.com Free Backup front-end | http://www.magikmon.com/mksbackup Your email 100% available | http://www.emailgency.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines

Re: Keep a file in memory an any cost
Joe: The index is modified very often and need to be flushed at regular interval, I don't want to handle read and write. JB: I already use mmap. JD: I already tried posix_fadvise with POSIX_FADV_WILLNEED, but this is not rock solid, if not used for a long time, data are not in the cache anymore. Bryn: mlock is what I was looking for. I'll make a try now. Thanks to the community.

Keep a file in memory an any cost
Hello I have a file, that is an index, it is open all the time by the application, but sometime the access are slow because the file was moved out of the cache. How can I keep it in memory all the time ? I can read it at regular interval, but this is a little over kill ? Any idea thanks. -- Alain Spineux | aspineux gmail com Monitor your iT & Backups | http://www.magikmon.com Free Backup front-end | http://www.magikmon.com/mksbackup Your email 100% available | http://www.emailgency.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
