General :: Save Iptables When Iptables-save Doesn't Exist?
Apr 14, 2011
I'm working on a Soekris net4801 that is running an unknown distro of Linux. The kernel is 2.4.29, and iptables is v1.3.4.
I can't work out how to save the iptables. I searched the whole system for files/folders containing the name "iptables" and got 3 results:
/user/local/lib/iptables
/sbin/iptables
/lib/iptables
I've tried iptables save, iptables-save and iptables save active.
"iptables save" and "iptables save active" give me an invalid argument error. "iptables-save" isn't a valid command. "iptables --help" gives me a list of valid switches, none of which have to do with saving.
how I can save the iptables?

I am unable to restore my iptables from iptables-save after upgrading Fedora. I cannot get iptables-restore to work, and I have resorted to entering rules manually using the GUI.

Config a CentOS iptables.I issued some iptables rules.the rules were effective at once.Then, I came with a "iptables-save", but the "/etc/sysconfig/iptables" file hasn't been updated, it still loads the defaults rules with CentOS after reboot.

my mediacenter is attached to an beamer with the optimal resolution of 1280*720 ubuntu 10.04 doesnt offer me this revolution (on my intel 915 graphis controller). this means i have to add this resolution to the possible resolutions. first i used cvt
Code:
cvt 1280 720 60
and got this result:
Quote:
# 1280x720 59.86 Hz (CVT 0.92M9) hsync: 44.77 kHz; pclk: 74.50 MHz
Modeline "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
then i added this to xrandr
Code:
xrandr --verbose --newmode "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
and
Code:
xrandr --verbose --addmode VGA1 1280x720
now i can select and use the new resolution - until next reboot. after an reboot 1280x720 is again not available. even if i work with sudo - the resolution isnt there....

I have Ubuntu 9.10 dual booting with Windows7.My ext3 /home is mounted as F: in windows.I share a firefox profile between them so that when i am in Windows my firefox uses the same profile as it does when in Ubuntu.It all worked great until recently. I am unable to save files by right clicking and save as. In the config i am unable to set a directory to save to. It neer asks me where to save to. Just nothing happens. some off my book marks are all messed up as well, my rss feeds have the same post on some random website every time i log on and i have to manually refresh to get the correct feeds back. I am unable to delete the random bookmark.

I am currently creating a usb device driver consisting of mostly read and write commands. It can successfully read/write using the bulk endpoints, however reading from the interrupt endpoint causes a system crash.As the crash happens whilst writing to kern.log, the file doesn't get a chance to close, therefore done of my debug printk calls are saved. Also, I get know response from using the magic sysrq key.
Does anyone have an ideas on how I can get any system information about what's causing the crash, or possible causes of the crash. (Using a usb sniffer running on another pc, I can see that the packet is coming in from the interrupt endpoint).

I have 2 different networks: the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping [URL]... on the gateway machine, it works, while it doesn't work on the private network.

I recently installed a new Ubuntu PC that runs iptables and PSAD. I had the same script on another Ubuntu PC, but when I copied the script onto the new PC, I got this error. I don't remember where I found the tutorial for this, all I know is that this is the script (Edited for my usage):
Code:
#!/bin/bash
# Script to check important ports on remote webserver

And the error message generated is:

I am running Ubuntu server 10.10 and trying to setup iptables rules in /etc/if-up.d/iptables
Quote:
root@host# cat /etc/network/if-up.d/iptables
#!/bin/sh -e
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
Problem is that iptables doesn't get updated and I don't see them when iptables -L is executed after reboot.

To expand: I'm trying to set up a box with l7-filter, and I need to patch and compile iptables 1.4.1.1 as part of the process. I ./configured it with the prefix= argument so it would install into /sbin instead of /usr/sbin, and I did a yum remove iptables before installing it so as not to get in the way of the original iptables, but I'm wondering if this is really necessary - it's kind of annoying, because removing the original iptables removes the init.d script, deregisters the service, etc. If I don't, is it possible that iptables 1.4.1.1 might get overwritten in a system update or something, or will yum see that I've got a custom/newer version in there and leave it be?

I switched to lxde, love the speed, but it has one major glitch: it doesn't save the settings. the most annoying: the setting " enable tapping" of the touchpad isn't saved afer a reboot. I tried the following:
delete ~/config/lxde ~config/lxpanel ~/config/pcmanfmand the other solution i found in the forum:Opensuse 11.3 LXDE Keeps Changing My Wallpaper Back To Default
I'm using opensuse 11.3, added repo lxde, updated everythng. So far, nothing.

I have recently installed Ubuntu 10.04 and from my id which has administrator rights, I am unable to save any files as well as unable to change the location in firefox. The firefox version is also in the snapshot as well as the options window. Is it that my profile has been corrupted or is there some bug in firefox.

less doesn't save command history, i.e. file .lesshst isn't created. If I create it manually, nothing writes to it too.OS AIX 5.3 I think linux users can have the same issue, hardly this issue depends on OS.

I have apache2 running under debian squeeze on a Seagate DockStar of a USB flash drive. To reduce the wear on the USB stick, I want to move all log files to RAM. What I did was to update create an entry in /etc/fstab to mount /var/log to tmpfs.Things seems to work except apache2. y start apache2, it complains aboutStarting web server:apache2(2)No such file or directory: apache2: could not open error log file /var/log/apache2/error.log.If I create the file, apache2 starts fine. Is there a step or two I am missing so I don't need to do this every time I reboot

I have a weird problem with Firefox with the following scenario: When I view a picture from a website in the browser and the pictures gets deleted from the server (while I'm viewing it) - I can't save the picture to my hard drive. Firefox always tries to download the picture from the web-server although it's in the cache. Resulting in an image file which contains the HTTP 404 response from the server. *lol*

If I change the keyboard shortcut for Open a Terminal in System > Preferences it will not stay in there if i log-out or reboot. When i log back in the shortcut is set to disabled, and I have tried different key combos and they give the same result. I am using Fedora 14 btw and hopefully you guys know of a solution. I tried making a custom command also using the gnome-terminal command but the terminal launches with a different directory other than my home directory when using that method.

When I go into YAST/sound my sound card is shown, and everything works pretty well, however, when I set the volume (other/volume), then exit and come back in, the volume levels are different than when I exited. When I reboot, it sets the master volume to 0%.

my problem is following: I'm running a bridged OpenVPN on my Debian. If the service is running, everything works fine: local and Internet, ftp, mailing from in and outside etc. But, when stopping OpenVPN, sending mails from inside (LAN) fails: I cannot reach smtp (postfix) listening on port 465. And even reaching mailboxes using IMAP gets horribly slow eg. in Thunderbird. Here is my firewall.sh script.

I have some japanese music files stored on a flash drive that the titles of which are in japanese originally. While in the flash drive, when I go to Properties -> Audio, the title is written in japanese. It does not allow me to edit the file, no matter what permissions I have on it, therefore I can't change the name to english. So, I tried Rhythmbox instead, and transfered the file there. I could change the name, however there is STILL a huge problem.
I have around 300 japanese music files, all of which have to be renamed into english.
I did all this for all of them in Rhythmbox, and clicked "quit" when I was done. When I came back to transfer the files to my MP3 player like usual, I opened Rhythmbox, and...
ALL OF THE FILES WERE STILL IN JAPANESE! It didn't save any of the work I did on editing them. But, I calmed down and thought "oh, you can save playlists! I am sure that if I save them on one, it will keep the edits!" I did this, and it saved nothing. It took me 2 hours to finish the renaming, just to find out that it can't save information edits at all.

In the indicator-applet-complete, I want the date and day to be displayed with the time. I open the Time & Date Settings, tick off the appropriate boxes, and nothing changes. The same is true for the Bluetooth icon. I can't remove the bluetooth icon from the indicator applet.It seems like a general problem with the indicator applet in that it doesn't save my settings.

For the background, I'll be using my router as a firewall with snort-inline enabled. I got 3 NIC's: one for the WAN, the second will be bridged to the WAN NIC for queuing traffic which snort-inline requires, and the third is the LAN NIC (the computer I use for everyday work). Here's how I have my interfaces set up:
Code:
# /etc/network/interfaces
# Loopback interface
auto lo
iface lo inet loopback
[code]....
From what I understand, queuing needs to be set up on the bridge. From the documentation I've read it's done like this:
Code:
iptables -A INPUT -j QUEUE
And then to forward traffic, I did:
Code:
iptables -t nat -A POSTROUTING -o br0 -j MASQUERADE
I've done this and am able to ping the router, obtain a DNS address from dnsmasq from the LAN computer. From the router I am able to connect to the internet (ping, links <address>...). From the LAN computer trafficking isn't getting forwarded, Firefox, links, ping all don't resolve.

For some reason, mport support has been removed from iptables 1.3.8 (was there in 1.3.7). However, multiport support is there. Does anyone here know why and what's the difference between the two in terms of operation? I have written firewall rules using mport. Can it directly be replaced 1:1 with multiport?
