I cant get my ubuntu machine to forward my vnc - I cant log on my windows machine running the server (it is DMZ and its ip is 192.168.1.2)Here is my firewall dump? What am I doing wrong? The important parts are connection sharing and forward allowance..
Code:
#!/bin/bash
ipt=/sbin/iptables
[code]....
One inconvenience I face now, though, is that I cannot tell if I have already forwarded certain messages or not, because the message is not automatically tagged as forwarded. how to set it up, so it would indicate in the list that the message has been forwarded?
View 2 Replies View RelatedI'm trying to setup my debian system so that I can access it's services from the internet
I have my router set to forward ports 21, 22, and 80 to the internal ip of the server, and internet port checking tools tell me the ports are open at my external ip.
On the debian I am running Apache, ProFTPD, and SSH Server, and they all work fine for me inside the network, but whenever I try connecting with my external ip, all connections are immediately refused.
So I don't know if its a problem with my router setup, with my debian system setup, or the setups of the servers.
I'm using madwifi linux driver (ath1) in monitor mode to capture some wireless traffic. I can see that all wireless traffic is coming well through the wireless interface (checked using TCPDUMP). What I want to know is how I can forward the captured wireless packets to a different Ethernet interface (e.g. eth2) in the same machine to send those captured packet out to a different computer.
I set 1 for /proc/sys/net/ipv4/ip_forward
for iptables, I tried this rule: iptables -A FORWARD -i ath1 -o eth2 -j ACCEPT
However, I coudn't read any packet from eth2 via TCPDUMP.
Mail going to invalid email addresses are being forwarded to postmaster@domain instead of being bounced. How can I fix this? postconf -d | grep mail_version gives the following: mail_version = 2.2.5

right now im using the nm-applet but i dont like it. it produces lags. i think the periodical ssid/broadcast check might be the cause :/it lags every minute or so...in games and skype it is very annoying! if there is a possibily to disable these scans in nm-applet it would be fine too.for the moment im "using" this wpa_supplicant config:

View 1 Replies View RelatedI use a Mac, but do all my development on a remote Linux machine which I access over SSH. Recently I've started using X forwarding to show some of the remote machine's graphical applications in windows on the Mac desktop. For the most part, this works really well - except that the applications look terrible: huge fonts, ugly widgets. Being the Mac-using perfectionist I am, I want to try and improve the look of these windows. Is there any way of using alternative widgets in an X-forwarded application? What would I need to install on the Mac, or on the remote machine?
View 1 Replies View RelatedWe are forwarding logs (perl script executed logs) to one Red Hat Linux box. We have to get 97 logs for each time the script runs. But we see inconsistent number of logs coming to Linux box. Like one time we got 56, other time 3 , other time 43.. like this.. We are sure that 97 logs are being forwarded. Checked the Rsyslog.config filer any filters and couldn't see any filter dropping them. When we run the tcpdump, we can see 97 connections, but logs are not there in specified location.
View 1 Replies View RelatedI'm ssh X11 forwarding xconsole to a Fedora 14 desktop. The font in xconsole is very large. I'd like to reduce it, but can find no means to do so. I looked at the XConsole resources file and there's no way to set a font type, or size. Man page for xconsole also has nothing in this regard. Changing the desktops DPI doesn't have the desired effect either.
I've been doing this X11 forward for years, and this is the first time I ever get a too large font in xconsole. Is there some other configuration or resource I'm missing?
I am running Fedora Core 8 as my mail and proxy server. My mail works properly for all users, but the problem I'm having is that when I create an alias for user's email to be forwarded to their gmail, the ISP bounces the mail. My ISP has given me an open relay to send mail.Is there somewhere in sendmail that I could put the user name and password of the ISP, so that the ISP will not bounce the forwarded mail. Or is there something that I'm missing?
View 1 Replies View RelatedI have configured 'passwordless' SSH between our machines using GSSAPI authentication which is all working beautifully (Active Directory KDC).I now want to make sure that the user's kerberos crednetials are forwarded as well using the 'GSSAPIDelegateCredentials yes' on the SSH client.However, it seems as though the openssh server on Red Hat 4.8 has not been compiled to support this, because if I run sshd in debug mode, I see the client 'delegating credentials' but nothing appears in the debug log on the server to suggest the the credentials have been received, and sure enough a quick 'klist' shows that the user does not have any tickets.So two questions:1. Am I right about openssh-server on Red Hat Enterprise 4.8 not supporting delegated credentials

View 4 Replies View RelatedI have my own internal bind9 server, for my local domain, and I forward internal requests for public domains to OpenDNS servers. This server is not in a DMZ, but is instead behind an dynamic NAT. I do not accept queries from the public network, only responses. I understand that DNS is primarilly a UDP protocol, so it can't pass through a stateful/nat. without a firewall allow.
I've done a little reading and learned that bind9 does not run 53 <-> 53 anymore (is now >1024 <-> 53), and modified my config so it works like bind4 did, but I am concerned that this makes me less secure. additionally, I'd really rather not have a completely open 53 rule, but it seems that if I constrain 53 traffic to my known forwarders, it interfers with some of my network services like transmission. so, what firewall rules would you guys recommend for recieving forwarded DNS query responses to my server?
I did a port scan on my server from outside my network and saw that port 10080 AMANDA is open.Amanda isn't installed on any of my computers or my server and the port is not forwarded by my modem or router. So why is this port open and how can I close it?
