I installed Fedora 13 some days back and been facing a weird network problem. on dmesg my NIC is showing Link up and Link down in alternate fashion. Even the lights on the port go on / off. this happens only for half hour once i start my pc, after that its fine.
View 2 RepliesI'm running a Poweredge 4400 with a 3com card and an intel card covered under e100.
I'm using centos 5.5 in its default server config coming from gentoo.
I have no link on either of the two interfaces, ever. The card initialises with ADDRCONF(NETDEV_UP): eth0: link is not ready and then falls back to half duplex but still with no connection.
I have manipulated most of the general settings that can be changed with ethtool.
Set to manual configuration with 100/full duplex
The cards are recognized alone and together. I have setup static interfaces with no problems. The ping to the local interface such that:
nic = 192.168.1.10
ping 192.168.1.10
we get back route times and all is well
ping 192.168.1.1
no route...
I have tried several different cables verified good other connections. I have verified the ports I am connecting to work correctly. I have manually shut down the onboard nic (in bios) and tried the 3com card alone. I have tried pci=routeirq, thinking there might be an irq issue.
If this was just the one card, I would install another and move on, but both nics are acting in exactly the same way.
Got a new router cause me old one gave up the ghost
how do I port forward to bring up me server again.
On my old set up NB1300 plus 4 I was able to set the IP and port and my site would open up OK
I want to do a simple port redirect, i.e. whatever comes trough whatever interface on port AAAA will get redirected to port BBBBI thought that iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport AAAA -j REDIRECT --to-ports BBBBhowever it doesn't work, e.g. nc -v -w2 -z localhost AAAA gives:
nc: connect to localhost port AAAA (tcp) failed: Connection refused
while
nc -v -w2 -z localhost BBBB

i am getting really pissed off with my new core i5 system I have a gigabyte p55m-ud2 mobo ([URL]) which's got a Realtek 8111D lan chipset it connected to my router after fresh install of ubun10 and then i installed MacOSX 10.6.3 and it worked there too then i came back to ubuntu and it didn't work anymore, after several restarts it was still not working until i took out the power cord and mobo battery, and reinstalled them back later which caused ethernet to work once again. but then after a while it started not to work anymore, which usually got fixed with a reboot. now this time i had ethernet working and i just resumed from screensaver and it stopped agian
there are no green or orange lights flashing at the back and when i take the cable out and reinsert it nothing comes on but with a shutdown they do come on i don't have this problem on the other harddisk which now has win7 and i some times manually change the sata cable to boot into windows and use itunes and some other stuff to load music to my iphone. I dont like to have dualboot and i dont like to use win7 either i just have it on the other hard disk just in case
is the manual switching of hard disk causing this to happen? why do i get it working with restart/shutdown and when i am using it fine it just decides to stop working after a resume from screensaver or sometimes for other reasons and why does none of this happen on win7 is there a way to reconfigure the ethernet drivers or other stuff without a reboot i am thinking it might be a problem with network manager or a bug or something network manager is really crappy and i used to use wicd until that started to do funky things ( like not connecting to hidden networks, launchpad Bug #473817)
I have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf
[Code]....
The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.
log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html
The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.
I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?

View 2 Replies View RelatedThe past couple days I've been attempting to use ndiswrapper to connect to my home network wirelessly and have run into a slight problem. I'm able to install ndiswrapper (of course), and install the driver. ndiswrapper -l comes up good, showing the driver is in place for my netgear wg311v3 card.
modprobe ndiswrapper I am able to get to work without errors, except, when i type ndiswrapper -ma it writes another file to /etc/modeprobe.d/ndiswrapper causing the deprecation error.
The card scans for networks, and I'm able type in my encryption key.
However it doesn't connect. | grep comes up with the error that the wlan0 link is not ready.
I think I've also been able to determine that the configuration I've put in to the card through the network manager is not actually configured.
Anyone know how I could possibly connect with the card.. It seems it should be able to work. alias wlano is also in place.
I have "D-Link DWA-125 Wireless 150 USB Adapter". I can use this wireless adapter on my laptop, i can use it on my desktop as well but only when windows is running, im a newbie to fedora, today is my 2nd day and 3rd night, so pretty exited about it. i have installed fedora 13 on a different hard-disk on my desktop. when the computer is booting, there is an orange light on the adapter glowing, it turns off when the computer reaches the fedora loading screen. If i see fedora's Network Configuration window under the hardware's tab i see the "D-Link DWA-125 Wireless 150 USB Adapter" listed along with my lan card. Now if i go towards the clock on the top right to get the wireless connection working, it shows wireless network disconnected. I have tried creating wireless connection manually by inserting the SSID, macadress, BSSID, ,WPA passkey etc, but still doesnt works. when i try connecting using hidden wireless connection, i receive window for inserting keyring password again and again, stating that the login password does not match. but during all this time, i still havent seen the orange light glowing activity on the external usb adapter. If i restart the computer in windows the adapter/wireless connection works. also have checked the Network service, it seems that the service is up and running. i really require some assisstance on this,
i have noticed this, that if i go under network configuration. the first tab over there, inside devices i cant see my D-Link adapter, but if i switch onto the hardware tab it shows my lan card as well as my D-Link adapter. so does it means that the driver is missing? or any service which is disabled, however at this point of time i can get only using wired connection. please assist me. with this issue, im also downloading the 500 complete update as well for fedora, hoping that it may make it work.
I recently got a Tplink TL-WN321G wifi device for my fedora box.

I have what I thought would be a simple issue: I have a Linux server and a bunch of people with Macs on a small business network.I'm trying to set it up so that using AFP, people can access the Linux server and drag and drop files to our test web development server. In each person's home directory there's a sym link to the /var/www/html directory, so that they can easily plop their test files there.I've got the hard part taken care of: AFP works, the Linux server appears on the network, and the Mac users can connect and log in.However, my sym link doesn't show up as a directory inside the Mac Finder...it shows up as an application. I don't know if this is something as simple as a permissions problem or whether I need to do more configuring to get AFP to play nice.

When I use the following command:

everything works fine. I can log in, and local port forwarding is done. Otherwise when I use the command:

I get an error "remote port forwarding failed for listen port 5500". However when I try remote port forwarding in WinXP by use of putty there is no problem...
I'm trying to use iptables in order to forward all the incoming packets for port 5555 to port 5556 on the same server (192.168.2.101).
I wrote the following commands:
iptables -A PREROUTING -t nat -i any -p tcp --dport 5555 -j DNAT --to 192.168.2.101:5556
iptables -A FORWARD -p tcp -m state --state NEW -d 192.168.2.101 --dport 5556 -j ACCEPT
I'm using a Debian servers, as router/firwall.. I've two ethernet interfaces into the server, one for wan and one for lan. The i use SNAT so my LAN clients can access the internet throgh the debian router. That is working... Now i want to be able to access servers on the LAN site from the WAN site, and i wanna use port address translation (PAT). I have a FTP server running on a lan server, so i'm trying to portward port 21.
iptables -t nat -A PREROUTING -p tcp -i eth1 -d (WANIP) --dport 21 -j DNAT --to 192.168.1.2:21
When people try to access my FTP from the WAN site, they are redirected to the local FTP server, and they are promted for crendentials, but when the credentials are typed, and the local ftp server should answer the wan request, the connections dies.
The wan clients are being promted for credentials, so they are redirected to the local lan server, but after that the connections dies, so i think there is some kind of nat problem, when the local lan server is trying to respond to the wan request..
Here i my iptables script:
#flush table
iptables -F

I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 225.0.0.1/23451 and 225.0.0.2/23452
Receiving on 225.0.0.1/23452 and 225.0.0.2/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [225.0.0.1/23452] take its datagrams from emitter [225.0.0.2/23452] and vice-versa!

View 3 Replies View RelatedI am using Fedora 14 x86_64 as the host and Windows XP under VirtualBox 4.0.4. I have added two ports (TCP and UDP) to the firewall settings in 'other ports' in the Fedora firewall setings. Do i need to do this?I noticed the port forwarding option in the Fedora's firewall settings which asks for either the ports to be forwarded to either local or an ip address. Do i need to do anything here?
In the settings under VirtualBox under Network adapter 1 (which is enabled) and attached to NAT, there is a port forwarding option in the advanced settings. Can the host and the guest port be the same number? If i use 'open port checker' to check if the tcp port is open in windows xp, will it work as it does in firefox under Fedora?
