  • /proc/net/dev and /sys/class/net/ bogus network interface names

    - by sfink
    I am constructing a list of network interfaces to monitor based on the contents of /proc/net/dev. But I am getting some bogus interfaces in the list: __tmp1104705027 __tmp974528607 Where do those come from? They also show up in /sys/class/net/: # ls -1 /sys/class/net/ eth0 eth1 eth2 eth3 lo sit0 __tmp1104705027 __tmp974528607 For now, I think I'll just ignore anything starting with __tmp, but I'd like to know what they are and where they come from. This is on a recompiled CentOS 5.3 kernel: 2.6.18-128.7.1.el5.tvh.7PAE #1 SMP PREEMPT

  • external HDD with SATA & USB interface? [closed]

    - by GregH
    Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

  • cannot send emails to other Web servers

    - by developer
    I'm trying to limit my server's open ports in CSF. The IPv4 port settings include: # Allow incoming TCP ports TCP_IN = "22,25,53,80,110,143,443,587,3654,53343” # Allow outgoing TCP ports TCP_OUT = "22,53,80,113,443,465,995,3654" # Allow incoming UDP ports UDP_IN = "53" # Allow outgoing UDP ports # To allow outgoing traceroute add 33434:33523 to this list UDP_OUT = "53,113,123" As you see, I have port 25 open in TCP_IN but have removed it from TCP_OUT. The reason is I wanted to have my mails transmitted over smtps, so I have port 465 opened instead in TCP_OUT. Since I am using Rouncube in Directpanel, I have also set the following in Rouncube's config.inc.php: $config['default_host'] = 'ssl://mail.mydomain.com'; $config['smtp_server'] = 'ssl://mail.mydomain.com'; $config['smtp_port'] = 465; However, when I remove port 25 from TCP_OUT, I no longer can send mails, say, to gmail, though I can send mails to own. But I can receive all mails. Please let me know if I need to make any further changes. Do I need to disable port 25 at all, to have my mails sent via ssl. Thanks

  • Rate limit a wireless interface

  • iptables forwarding between two interface

    - by broody
    So I have a linux box with two wireless interfaces, one is a station and the other an AP. wlan0 (station) - Connected to the internet connection wlan1 (AP) - Other clients connect to it. I would like for clients connected to wlan1 to be able to access the internet on wlan0. And I'd like to do this with iptables as my kernel doesn't have bridging support... Here's what I've tried so far with iptables but it's not working: iptables -A FORWARD -i wlan0 -o wlan1 -j ACCEPT iptables -A FORWARD -i wlan1 -o wlan0 -j ACCEPT I'd appreciate any help.

  • Filtered Router Interface

    - by jviotti
    I'm having some problems with a Scientific-Atlanta DPR2320R2. In specific with the WIFI. A few months ago I changed its password and username and now I can't remember. So I tried cracking it with Hydra but it drove things worse. Content of webadmin was rendered partial, and threw lot of errors. I then reseted the router. I found myself abled to browse the web with ethernet-connected pc. Wifi is configured by registering the device's MAC Address, and indeed the router has been reseted and register MAC address were lost. No device could connect to wifi. In fact, the device does not even recognize the network. I tried the pointing to 192.168.0.1 to restablish the MAC's. But I couldn't connect to the router access point. Tried listing up hosts: $ nmap -sP 192.168.0.0/24 Starting Nmap 5.00 ( http://nmap.org ) at 2012-12-11 01:18 ART Host 192.168.0.1 is up (0.0018s latency). Host 192.168.0.11 is up (0.00025s latency). Nmap done: 256 IP addresses (2 hosts up) scanned in 59.62 seconds Then checked 192.168.0.1 was really up by sending pings. It responded to all my pings. I quick-scanned the access point: $ nmap 192.168.0.1 Starting Nmap 5.00 ( http://nmap.org ) at 2012-12-11 01:08 ART Interesting ports on 192.168.0.1: Not shown: 999 closed ports PORT STATE SERVICE 80/tcp filtered http Nmap done: 1 IP address (1 host up) scanned in 6.73 seconds Look the state of the port 80: FILTERED. I'm pretty confused now. Any suggestion would be appreciated. Thanks in advance.

  • Router failover not detecting outside interface link lost

    - by Matt
    Suppose I have two routers configured in master/slave configuration. They look something like this (addresses are not real ones) 123.123.123.10 <===> [eth0] Router 1 (10.1.1.2) [eth1] ===> +----------+ | 10.1.1.1 | ===> LAN 172.123.123.10 <===> [eth0] Router 2 (10.1.1.3) [eth1] ===> +----------+ The 10.1.1.1 is the default route for the Network (10.1.1.0). What's slightly different in this config to other's I've seen is that I don't have an external virtual IP. Also, the 10.1.1.1 addresses are in real life, public IP's (not private ones shown here). This is more of a router setup than a firewall setup so I'm not using NAT here. Now the issue that I'm having is that I can't see any way to configure UCARP or VRRP to monitor both eth0 & eth1 and fail over to the backup router should either of them go down. What I'm seeing is that if Router1 is the master and I unplug eth0 on router1, it doesn't fail over to router 2. However, it will if instead I unplug eth1 of router 1. In VRRP I see there is a cluster group, but it seems that for this to work you need to have virtual ip's or vrrp instances rather than actual interfaces assigned to it. I hope my explanation is clear. How do I get around this?

  • dnssec zonesigner ignoring out-of-zone data

    - by jordi12100
    I am trying to configure DNSSec with BIND9 on CentOS 6.4 running DirectAdmin control panel.

  • How to set the preferred network interface in linux

    - by Mike Cooper
    I have my network set up like this. http://docs.google.com/Doc?docid=0AZ1YxuLE4djaZGhqN2s1NmRfMjhjNjc0Ym1meg&hl=en In words: I have a machine (Calcium, running Arch Linux) that has two network interfaces. eth0 is hoooked up to a router, and is gigabit. Eth1 is hooked up directly to the university network over 10Megabit. The router's uplink is hooked up to the university network as well, and it is also 10Megabit. Currently (I believe) all traffic on Calcium is going through eth0, through the router, regardless of whether it is internal or external. (How can I confirm this?) Ideally, traffic that is destined for the internal network (192.168.10.0/24) would travel over eth0 to the router, and wherever it is going. ALL other traffic should go over eth1.

  • Virtual machine won't connect to networking interface

    - by Keyo
    I have moved my virtual box hard drive (.vdi file) from windows7 on a laptop, to windows7 on a desktop. No big deal I thought. The OS is ubuntu 10.10. Now networking is broken. I don't have a solid understanding of windows networking, maybe someone can help. Anyway, the networking no longer works. I've tried to setup eth0. I have virtualbox setup in bridge mode, my wifi connection on windows to an intel card on the virtualbox side. I think it might be something to do with windows not allowing the connection to bridge properly (security issues). I've provided some screenshots, which will hopefully help.

  • ProFTPD mod_tls is not loaded properly?

    - by develroot
    The server is running CentOS 5 with DirectAdmin. I am trying to get ProfFTPD work over TLS, however it seems that proftpd is lacking mod_tls support, even though it was compiled with mod_tls. # proftpd -l Compiled-in modules: mod_core.c mod_xfer.c mod_auth_unix.c mod_auth_file.c mod_auth.c mod_ls.c mod_log.c mod_site.c mod_delay.c mod_facts.c mod_ident.c mod_ratio.c mod_readme.c mod_cap.c As you can see there is no mod_tls.c, however, the DirectAdmin configuration file for proftpd suggests that it was built with TLS support: # cat /usr/local/directadmin/custombuild/configure/proftpd/configure.proftpd #!/bin/sh install_user=ftp \ install_group=ftp \ ./configure \ --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var/run \ --mandir=/usr/share/man \ --without-pam \ --disable-auth-pam \ --enable-nls \ --with-modules=mod_ratio:mod_readme:mod_tls And all I get when I try to connect over FTPS using FileZilla is: Raspuns: 220 ProFTPD 1.3.3c Server ready. Comanda: AUTH TLS Raspuns: 500 AUTH not understood Comanda: AUTH SSL Raspuns: 500 AUTH not understood Am I missing something? thanks.

  • Migrating email forwarding entries from DirectAdmin to Google App (Free edition)

    - by bobo
    I have a website hosted in a shared hosting account and it contains a DirectAdmin (DA) control panel. From there, I can see some email forwarding entries. I would like to migrate the email server to the Google App's, I am going to change the MX records to point to Google email server in the DA. For the existing email accounts that I see in the DA, I will re-create them in the Google App. But for those email forwarding entries, I am confused. If I keep them there, will they still work after I have changed the MX record pointing to the Google email server? If not, this means I will need to re-create them in the Google App, right? Unfortunately, Google App (Free edition) does not seem to allow email forwarding like those in DA. Unless I choose to use other editons (http://www.google.com/support/a/bin/answer.py?answer=175745). In DA, when I have created an email forwarding entry such as [email protected] - [email protected], I do not really need to create a dummy [email protected] email account and DA will still do the forwarding properly. The best I can do now, without upgrading the Google App edition, is to simply create dummy email accounts in the Google App and setup forwarding inside that email account, is this correct?

  • How can I protect Chrome user interface?

    - by Renan
    Google Chrome has a feature to change between Google accounts which allows several users to have their customized extensions, history and whatnot retrieved instantly. It doesn't, however, protect someone else from checking anything google related. That means anyone with access to your computer can check every google account that was setup as user in Chrome. How can I prevent that? I first thought of checking a box with the option to have Chrome request for password upon user change but that doesn't seem to exist.

  • What to use as a file server with a web interface and user management on MAMP

    - by Timo
    I want to set up file/photo sharing for a largish group of friends and family. Flickr, Picasa etc. are not optimal solutions because setting up accounts, sharing albums and navigating privacy settings is going to be overwhelming for some of the people. I just want to be able to give people a URL, a username, and password and have it be easy peasy. I want something very simple and easy to use (for the user) like MyTunesRSS. I've looked at a complete "social" solution like Elgg but that feels like using a cadillac to kill a fly. I only need: User management Simple upload / download of files Plug-into-MAMP ease of setup is a bonus Search / metadata / tags / commenting not necessary but also earns bonus points Free / cheap licence What would you recommend?

  • Add IPv6 support to DirectAdmin server

    - by George Boot
    I just set up an new DirectAdmin, and I want to prepare it for IPv6 use. My ISP have gave me an range of IPv6 addresses that I can use. Lets say that address is 2a01:7c8:**:1f::. My neworkadapter user DHCP to resolves its IP-addresses. When i type ifoncig eth0 I get the following result: eth0 Link encap:Ethernet HWaddr 52:**:**:**:ce:f3 inet addr:37.**.**.44 Bcast:37.**.**.255 Mask:255.255.255.0 inet6 addr: 2a01:7c8:****:1f::/64 Scope:Global inet6 addr: fe80::5054:ff:fe87:cef3/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:38941 errors:0 dropped:0 overruns:0 frame:0 TX packets:29439 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3779534 (3.6 MiB) TX bytes:5089379 (4.8 MiB) As you can see, I have an IPv6 address set, but I can't ping6 an IPv6 host. I get the error: connect: Network is unreachable. I decided that I needed an gateway, so I tryed to add one: ip -6 route add default via 2a01:7c8:****::1 dev eth0 (2a01:7c8:**::1 is the gateway of my ISP). But it trows an error: RTNETLINK answers: No route to host. Does somebody know what to do, and how to solve this issue? Thanks a lot!

  • PDU management interface has low availability - product flaw or isolated issue

    - by DeanB
    Our colocation provider has supplied us with APC AP7932 switched 0U PDUs as part of several cabinets they provide us. We have had a lot of trouble with the network management aspect of these PDUs, which I'll describe below. We are moving to cage space in the same datacenter, and plan to provide our own PDUs, so I'd like to determine which enterprise-grade PDUs have been reliable performers from a remote management perspective. Our colo-provided PDUs are configured to support management via an SSL web UI and via telnet. We updated the firmware on all of them to the current version as of NOV2011. They respond to pings reliably, and we have no reason to suspect a network layer issue. However, we experience frequent hangs, timeouts, disconnects, and general unavailability from the embedded management host in all of the PDUs. We occasionally have to restart the microcontroller on the PDU to recover from what appears to be an occasional hard fault. The outlets stay powered (thankfully), but the management aspect is so unreliable that it has become an ops liability - we can't be confident that we could get into the PDU to power cycle a host if we needed to. We have 3 PDUs that all exhibit identical behavior. There are many manufacturers of enterprise-grade 0U switched PDUs, all with comparable features. If I looked at the datasheet for our current PDUs, they would appear to be a good fit -- only with the benefit of suffering through using them do we know to avoid them. I'd like to avoid picking a PDU that looks fine on paper, but has similar reliability issues. What has been others' experience with switched PDUs? Is this level of flakiness normal?

  • Domain names timing out after VPS IP change

    - by Fourjays
    I rent a CentOS 5 VPS from a UK-based provider, with DirectAdmin also installed. On Thursday night, they carried out planned maintenance to changed the two IPs I had been assigned to two new ones. On Friday, after the change had taken place, I updated my domain name records to reflect the IP change. Since then, all of the domains pointing to the VPS are timing out. Additionally, DirectAdmin was also not responding, but was was resolved by running the ipswap scripts as found in the DirectAdmin knowledgebase. It did not fix my domains though. I have contacted the VPS provider but I have been waiting for a response for some time now. I have checked again, and again, and all the IPs referenced in DirectAdmin are correct. If I go to the server IP in my browser it responds with "Apache is functioning normally." Email accounts on the server are also functioning correctly. But if I access a domain itself, it times out. Running a ping and a DNS look-up, I can confirm the nameserver IPs are correct. If I run a trace route it reaches an IP that is similar to my VPS IPs (last 2 blocks are different) before timing out (it never shows my server IP). I am relatively new to VPS management so don't have a vast wealth of experience with troubleshooting problems on them. I have checked all of the httpd configuration files, which don't seem to have any IP references in them at all. Looking in the Apache error logs, what errors there are do not coincide with times I have tried to access the site. Is this issue at my provider's end? Is there anything else I can check or test, to rule out post-IP-change problems with my server configuration? It was all running fine prior to the IP change.

  • Web interface to allow users to change their Active Directory password

    - by csexton
    I have a few web applications that use Active Directory to authenticate. What I would like to be able to do is provide a simple web page that would allow users to update their AD password. This wasn't a problem when the majority of the users had windows machines that connected to this AD server (and could ctrl-alt-del to change the password), but we are moving away from that and the AD server is mostly for web apps. Is there a simple solution for this, or am I looking at the big LDAP managers?

  • External mouse clicks not working during UAC prompt/windows or other elevated privilege programs

    - by user26453
    I have a Logitech Revolution VX, a small portable mouse. I use it on my laptop running Windows 7 64bit Professional. When a UAC prompt comes up, I can use the mouse to move the pointer, however any clicking via the external mouse is disabled. I have to use my trackpad to actually click. This continues on into whatever UAC window comes next, such as a program install. The mouse pointer can move via my external mouse, but no button clicks register except on the trackpad. This also happens if I am to right click a program and select "Run as Administrator". The external mouse will move the pointer, but no button clicks work. I've tried to google for this issue but haven't found anything. To be it seems generally a problem with my external mouse driver not running with elevated privileges itself. Any help would be appreciated.
