Maybe you should set your statics IP in the DHCP server or in the router (it could work as DHCP server). Check this tutorial. There are some considerations about setting a static IP in the client or in the DHCP server. Take a look to this.

I once had such problem on freshly installed distro (it was CentOS or Debian).the culprit was avahi deamon (mDNS) (don't know what it was trying to resolve on every ping and why). Stop this daemon if its running and try to ping again

I just ran into this problem. By default install on my raspian wheezy, hostapd is started as S01 in services. This makes it start before ifplugd which configures eth0 and wlan0. The reason for this is that S01h[ostapd] < S01i[fplugd] since scripts are sorted in alphabetical order for execution. I think that the bridge gets a hard time getting configured ...

Besides from above answers, you can also use wifi-menu on Arch Linux. It will show a CLI-Based GUI and you can choose a WiFi from WiFi list that is shown. wifi-menu depends on dialog though. You must have it installed first.

Packet Dropped seen from ifconfig could be due to many reasons, you should dig deeper into NIC statistics to figure out real reason. Below are some general reasons NIC ring buffers getting full and unable to cope-up with incoming bursts of traffic CPU receiving NIC interrupts is very busy and unable to process some cable/hardware/duplex issues some bug in ...

Probably to late but here goes. With Solaris 10 you need to edit /etc/resolv .conf and cp /etc/nsswitch.dns /etc/nsswitch.conf Also i am assuming you have bridged network in Virtual Box. If you have Host only it won't work. But as a test try to ping 8.8.8.8 Google dns server if you can then the solution stated above will work, otherwise you don't have ...

In one machine you can only define your next gateway/hop. The second hop is configured as the gateway of the gateway, the third as the gateway of the gateway of the gateway and so on. The hops following to them must be set at those machines following. So you have to configure all 5 routers with the corresponding next hop.

The solution is fairly easy, just replace auto to allow-hotplug. So I ended up with this: allow-hotplug lo iface lo inet loopback allow-hotplug wlan0 iface wlan0 inet static address 192.168.150.1 netmask 255.255.255.0 allow-hotplug eth1 iface eth1 inet manual up ifconfig $IFACE ...

The good old arpwatch is still useful. Other than that, it might be a good idea to capture all network traffic for a few days and analyse it.

I would suggest that this is probably due to something blocking ICMP packets of types 3 and 4 from O365 back to your client PC. These packet types report on packet fragmentation across network links. I would have expected these to be classed as "related" packets for a connection and so permitted as part of a TCP conversation, but perhaps not. If you have a ...

As per man page command should be: ethtool -s devname speed X duplex half|full I think --change is long option and -s is a short option. ethtool -s devname [speed N] [duplex half|full] [port tp|aui|bnc|mii] [mdix auto|on|off] [autoneg on|off] [advertise N] [phyad N] [xcvr internal|external] [wol p|u|m|b|a|g|s|d...] [sopass xx:yy:zz:aa:bb:cc] [msglvl ...

Found answer from jm_ on irc.debian.org commented out allow-hotplug eth0 from the The primary network interface in the file /etc/network/interfaces. eth0 was occupying the default gateway which was not getting free for WIFI.(detected this by using command ifconfig eth0 down). thanks to all again.

Unfortunately that's the wrong way to achieve this. DHCP is a protocol that works completly in broadcast. From the discovery, to the offer, to the request and the acknowledge; every single step happens over the broadcast address 255.255.255.255. The DHCP server normally uses option 54 to identify himself (See RFC2132, Chapter 9.7). If you have a rouge DHCP ...

As far as i know it is possible to add networks with the same essid. Do that twice with different passwords or use a power lan connection. Both should work.

This is answered on http://serverfault.com/questions/692979/block-brute-force-attacks-on-exim2/692991#692991. Part of the issue seems to be allowing authentication on an plain text connection. Fail2ban should catch after 3 tries, but may need additional regexes.

The route or the ip utility get their information from a pseudo filesystem called procfs. It is normally mounted under /proc. There is a file called /proc/net/route, where you can see the kernel's IP routing table. You can print the routing table with cat instead, but the route utility formats the output human readable, because the IP adresses are stored in ...

Ok, I feel very stupid. I rebooted the TimeCapsule and now it works. "Did you try turning it off and on again" was the solution. The reason was probably this: I switched the IP network range of my router from 192.168.178.0 to 192.168.1.0, so that the smbd on the TC probably got confused...

It looks like the Linux support is dead. There are tools for tracking network usage like the one on this one. There are also tools for sending and receiving texts like this one called gnokii.

Okay, this on turned out to be WTF LOL squared... I got a hint that it was most likely ICMP packets being filtered by the firewall. So when you stumble upon this issue check it out. In the article I found on Hacker News one reads: ssh did not work. It would connect, flip some data back and forth (as shown with -v) and then would hang. Certain websites ...

You can use Python and Paramiko scripting for this. Sorry for the plug but I have already a script for this posted here "http://certifiedgeek.weebly.com/blog/network-scripting-via-ssh-with-python-and-paramiko" where the script is located in "https://github.com/cwgueco/netscript" This script "netscript.py" has this options: netscript.py -t <target> -u ...

Depending on what you are running on the raspberry pi with wifi and ethernet you could be able to install iptables: Then configure ip forwarding by: echo 1 > /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward=1 # to make ip_forwarding persistent across reboots and an iptables rule to masquerade outgoing traffic iptables -t nat -A ...

One possible cause is the firewall rejecting ICMP traffic. To test the hypothesis turn off the firewall in yast and try again.

After some researches and tries... These "network printers devices", could implement some protocols, being one of them the one called "HP JetDirect", also known as "Raw", "JetDirect", either just "9100". It seems to be the most common protocol supported by network printers. A network printer configuration sample: The JetDirect protocol is just an ...

If top is showing high loads, and you don't know if the process causing it is doing processor time or is doing network i/o (not local i/o) how can you find that out? Network I/O is not taken account in the Linux iowait metric, unless it is part of an NFS transaction in which case it is considered as disk I/O. So, is there a way to find out more ...

As long as the device is used for ppp traffic, it is not possible to run AT commands at the same time1. For this reason all modern modems will provide more than one serial interfaces, e.g. /dev/ttyUSB0 and /dev/ttyUSB1 (or /dev/ttyACM0 and /dev/ttyACM1 for USB CDC modems on linux). Back in the days when phones had RS-232 compatible connectors (perhaps with ...

I understand that network printers use a protocol called RAW (or Jetdirect), is that correct? Yes. There are two network protocols for print jobs that are still relevant today: LPD, running on TCP port 515, and JetDirect, running on TCP port 9100. LPD was designed by Berkeley for BSD UNIX in the old days. It's pretty much obsolete now, but it's still ...

CUPS allows you to share printer with (at least) IPP, LPD and samba protocols out of the box. IPP is supported by most operation systems and IBM was part of the Printing Working Group which came up with IPP so it's likely supported in AIX as well. Also, samba has AIX protocol so one or the other should work. search for AIX But none of the documents I came ...


0

You'll probably want to install CUPS; according to this page it's definitely available for AIX as well. Once you've configured it to recognize and use your printer, you probably want to check here for instructions on how to share it across the network. Alternately, you can use samba to share the printer; nowadays most OSes speak the protocol.

So, it seems I've managed to find a (temporary ?) solution where wlan0 is the default route. I don't need to know the wifi gateway. The key is to follow @goldilocks idea to script routing processes. But this solution allow to keep eth0 and wlan1 to run on dhcp. So I've added the file /etc/dhcp/dhclient-enter-hooks.d/post-wlan0 (and chmod +x to it) which ...

I'm understanding that you want to use the RPi to allow a wifi-connected UPnP camera to be moved around between networks and use the RPi to connect to a wireless network at each site. Is that correct? Is there some reason you can't access the camera directly from the network without the RPi routing? Do you have routing enabled on the RPi? To enable ...

You can use iptables + ip-route together to achieve this. The idea is, iptables "mangles" a specified packet by "marking it", and then later, the ip route rules can direct such marked packets to a different gateway, ie, interface. I found a concise and simple example for you: http://lartc.org/howto/lartc.netfilter.html The example is that you have two ...

I can give you a sort of partial answer that has to do with how I would approach this, with the caveat that I don't use a networking configuration service at boot; I just write my own scripts to get whatever I want done. That said, to test this you can just could just comment out everything in /etc/network/interfaces except for lo and wlan0, using the ...

Are you a network administrator? If you aren't, I think that your IT manager was not concerned by the overuse of bandwidth but rather with the fact that 1) you were tinkering with the network and 2) nmap scanning could crash applications: It should also be noted that Nmap has been known to crash certain poorly written applications, TCP/IP ...

This is easy enough to measure, at least if you nmap a host your machine is not otherwise communicating with. Just use tcpdump or wireshark to capture the traffic, limited to that IP address. You could also use iptables counters, etc. I did so (using wireshark), the machine I tested on has fewer open TCP ports (5), but the totals were 2009 packets, 118,474 ...

I've seen (broken) smart switches going down due to nmap activity, but that was when nmapping a subnet (so ARP traffic for a lot of different endpoints). That may be the kind of problem he's thinking of. Now Intrusion Detection Systems do try and detect port scanning activity and may be configured to block the IP address of the host doing the scanning. If ...

I thought NetBSD probing this via usage of Vendor- and PCI-ID. Maybe pcidevs.h and pcidevs_data.h is helpful for you.

I think you could either use dhcpd.conf or some post-boot ifconfig(8) scripting to reassign the interfaces by referencing their hardware MAC addresses which will be unique even if you're using multiple identical NICs. It would be nice to be able to reference the MAC addresses instead of the XXn interface names but ifconfig(8) doesn't appear to have that ...

No, you cannot know beforehand what driver will be attached for some mystery hardware configuration. Of course if you're working from a hardware inventory of known configurations and you have pre-determined what what driver will be used for each type of interface in your known systems, then it's pretty deterministic. On the other hand as the system is ...

I understand the routing table is a "fall through" table Not really. The routing table is ordered from "most specific route" to "least specific route". Your default route is via br0, and is defined as the route of last resort because there is no netmask (i.e. genmask is 0.0.0.0). because the 1st entry is 0.0.0.0 all traffic will go through the tun1 ...

I think you can use route command instead of iptables: route 111.112.113.114 gw 10.182.1.5 Or you can also push the route from openvpn server's side.

AFAIK, lsof has not been ported to cygwin. You could use the Microsoft netstat utility there: netstat -aon | awk '$1 == "TCP" && $4 == "LISTENING" && $2 ~ /:8000$/ {print $5}' | xargs kill

Did you try setting the lo interface up? I have seen networking not working in a namespace when lo is not up, so try this: ip netns exec netns1 ip link set lo up

Your netstat command shows that you are not running an ssh server on the target machine. You need to install this from the repository; on Ubuntu it's called openssh-server. Installation will automatically start the daemon. After it has been installed, you should get output something like this, which shows that the sshd process is LISTEN-ing on port 22: ...

Ok: First, you have two interfaces with sequential IP addresses on the same subnet—if you're trying to spread load between them to get higher throughput (say, you want to turn two gigabit NICs into one 2 gigabit NIC), there are much better ways to do this! The general term would be "bonding". Search for "network bonding" or "NIC bonding" to find some stuff. ...

I think this would work, though I do this for ssh into a Linux VM and not rdesktop. The principle is the same though. In VirtualBox, go into Settings -> Network for your VM and click Port Forwarding. There you set up a rule with Protocol=TCP and Guest Port the default port for rdesktop. Sorry I don't know that number, the man page for rdesktop doesn't say. ...
