Yes, you can write the value in all files, but it hasn't any real effect....
I've tried write values manually (echo 15 >
/proc/sys/net//ipv4/tcp_fin_timeout ), also I've tried with sysctl
(sysctl -w net.ipv4.tcp_fin_timeout=15).
Then, I see the files with:
cat ------> cat /proc/sys/net//ipv4/tcp_fin_timeout
or
sysctl -----> sysctl net.ipv4.tcp_fin_timeout
All methods write and show correctly my own value (15), but SO continue
using his defaults value (60 seconds).
I've tried to restarting the network service and restarting the system
(doing before permanent, these change) , but nothing change.
Regards and Thank you.

Hello,
I myself tried to do the steps that you had mentioned the email, but it was of no use.
I then did the following steps as shown in the screenshot , I think I have got it.
[root@amit ~]# cat /proc/sys/net//ipv4/tcp_fin_timeout
60
[root@amit ~]# cat> /proc/sys/net//ipv4/tcp_fin_timeout
30
[root@amit ~]# cat /proc/sys/net//ipv4/tcp_fin_timeout
30
To make sure that the changes are made in the right file, I went all the way don to the TCP_FIN_TIMEOUT file, and saw that the changes were there.
[root@amit ~]# /sbin/service network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0:
Determining IP information for eth0... done.
[ OK ]
[root@amit ~]# cat /proc/sys/net//ipv4/tcp_fin_timeout
30
[root@amit ~]# cd /proc/sys/net//ipv4/
[root@amit ipv4]# cd tcp_fin_timeout
bash: cd: tcp_fin_timeout: Not a directory
[root@amit ipv4]# vi tcp_fin_timeout

"tcp_fin_timeout" 1L, 3C
[root@amit ipv4]# cat tcp_fin_timeout
30
As you could see that the changes are there, so I guess that you can make it to 15 sec.
Try it and let us know

Hello!
I'm new in this list. I hope you can help me and I can help to other
from now.
I'm trying reduce the timeout of TIME_WAIT tcp connections status, but I
don't get it.
I set the value of /proc/sys/net/ipv4/tcp_fin_timeout to 15:
echo 15> /proc/sys/net/ipv4/tcp_fin_timeout
I think that this should be sufficient, but the SO continue kill
connections after 60 seconds of TIME_WAIT, instead of 15...
Can you help me?

Hi,
I've been trying some wget options to download
"http://archive.kernel.org/fedora-archive/core/updates/5/i386/"; (only the
contents of i386)
to my current directory but it only downloads index.html and robots.txt
# pwd
/5/i386
# wget -r -nc http://archive.kernel.org/fedora-archive/core/updates/5/i386/
it creates the directory hierarchy and downloads index and robots only. I just
want to get all the files that are inside the i386.
what options should i use?
thanks,
Sir June
