• how to split a pcap file into a set of smaller ones

  - by facha

  Hi, everyone I have a huge pcap file (generated by tcpdump). When I try to open it in wireshark, the program just gets unresponsive. Is there a way to split a file in set of smaller ones to open them one by one? The traffic captured in a file is generated by two programs on two servers, so I can't split the file using tcpdump 'host' or 'port' filters. I've also tried linux 'split' command :-) but with no luck. Wireshark wouldn't recognize the format.

• MySQL Workbench sends computer name with login not IP

  - by Android Addict

  I am attempting to connect MySQLWorkbench to a remote MySQL Server. The server has granted access to user@IPAddress However, when I try to connect MySQLWorkbench, it sends user@computername instead. How do I configure the connection to use the IP address instead in MySQLWorkbench? Reference: The remote server is on the local network, so I need to use the local IP address assigned to my client. EDIT What I have tried so far: from the server: mysql -u user@IPAddress -p --host=(ServerIPAddress) Returns: mysql> So that tells me the user account is operational. Furthermore, I confirmed it exists using: select user from mysql.user; returning a table of all users, of which the user I am using is present. I have also opened the port 3306: sbin/iptables -A INPUT -i eth0 -s clientIPAddress -p tcp --destination-port3306 -j ACCEPT Still I encounter Access Denied

• Xerox Workcentre 3119 and Linux

  - by Milan Babuškov

  I'm trying to get Xerox Workcentre 3119 printer to work on Linux. It's a multifunction device (printer and scanner). I run the CUPS web interface at: http://localhost:631/ and it recognizes it on USB port and even suggests Gutenprint driver from the list. When I try to print a test page, the printer goes through "warming up" process (i.e. lights blink and sound is heard) but does not print anything. There are no errors in /var/log/cups/error_log and access_log shows as if everything is ok. The printer works fine in Windows XP. Does anyone have any experience with this printer on Linux?

• Print server does not show up on router's attached devices

  - by AshTee

  Recently I bought a new more powerful wireless N router, DLink DIR 628. So I removed all connections from the previous router (Netgear WGT624) and connected them as they should be to the DLInk router. Everything works fine except for the print server. I have Hawking print server connected to HP Laserjet 6P parallel port printer. It works well with the Netgear router. But when I connect it to the DLInk router, it does not even show up in the LAN computers list. I am not sure what is going on. There is a utility called PSAdmin that can talk to the Hawking print server if I switch to Netgear router. With that utility, I can get the assigned IP address to the print server. But when switching to DLink router, even the PSAdmin fails to find the print server. I have been trying various things for last couple of days in vein. Please help.

• Why does TeamViewer launch a web server?

  - by OverTheRainbow

  Hello I just read this article which I find concerning: "After 90 minutes of troubleshooting, Nash traced the problem to TeamViewer, which he used to remotely administer the client's servers. It turns out the program had opened up its own webserver on the client's machine as soon as Apache went down and in the process made it impossible for the client, a large provider of business software, to restart its proper website." http://www.theregister.co.uk/2009/07/24/teamviewer_snafu/ I started using TeamViewer recently because it's just much better than UltraVNC (runs on both XP and Vista, the server dials out instead of requiring the user to open a port on their router + better performance than UVNC)... but I thought that TeamViewer had both the server and client connect out to TV's web server for data to flow between the two hosts. Why does TV even need to open a web server on the server host? Thank you.

• Firewall issue with multiple SIP PROXY / REGISTRAR servers

  - by MikeBrom

  Hi We have a pair of Internet-facing SIP PROXY/REGISTRAR servers (for resilienced and load-balancing). When a SIP phone registers, it will be handled by one of the REGISTRAR servers (round-robin DNS) - and since this registration is renewed, the firewall port/address translation is maintained. Therefore, when a call is to be sent back to the phone the INVITE message passes successfully through the firewall. However, it is likely that the phone may register with one of the two servers, but the INVITE may come from the other. In this situation, the call fails since there is no translation in place on the firewall. Is there a feature in the SIP protocol to facilitate this? Any other ideas? As our traffic grows, we will no doubt end-up with more than two servers - so the problem will escalate. Thanks, Mike

• IIS 7 Request routing

  - by Abraham Durairaj

  Not sure the title is right. I have my site configured in IIS7 and I have another partner site which runs on a different port eg. http:// localhost:1234 /mysite. Can I have my parent site to have a virtual site http:// localhost /mysite to route requests to the partner site http://localhost:1234 /mysite. I should not redirect but I should basically proxy the requests. Any help here is appreciable. Thanks in advance.

• Remote logging for multiple Apache virtual hosts using syslog-ng

  - by James

  I'm running a couple Apache web servers that each have 4-8 separate virtual hosts on each of them. I'm trying to setup a dedicated log server that stores each virtual host access and errors logs in a separate directory for that virtual host. For example on the logging server, /var/log/remove/10.0.0.2/virtualhost1 contains access_log and error_log /var/log/remove/10.0.0.2/virtualhost2 contains access_log and error_log /var/log/remove/10.0.0.3/virtualhost3 contains access_log and error_log and so on... Right now I have it split up by host but I can't figure out how to do it additionally by virtual host. Here are the relevant lines from the logging server's syslog-ng.conf source r_src { tcp(ip("0.0.0.0") port(5140)); }; destination r_all { file("/opt/splunk/logs/$HOST"); }; log { source(r_src); destination(r_all); }; Any help would be appreciated. Thanks!

• Zabbix machine is going crazy with HD writes!

  - by gshankar

  I recently installed Zabbix on a Ubuntu box I had sitting around. It's only monitoring 2 servers but I've noticed that it's continuously smashing the HD with writes. I don't remember Zabbix being this resource heavy when I've used it in the past... Any ideas on why this is happening and what I can do about it? Running iotop gives me this: 1710 be/4 mysql 0.00 B/s 102.12 K/s 0.00 % 0.00 % mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/run/mysqld/mysqld.sock --port=3306 1723 be/4 mysql 0.00 B/s 0.00 B/s 0.00 % 0.00 % mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld I'm pretty sure it's Zabbix that's causing all that mysql activity as it's the only thing which uses mysql which is running on the box...

• vsftpd not allowing uploads. 550 response.

• In IIS why do HTTP requests use the host header, and FTP requests do not

  - by Keeno

  So.... In IIS, if you use the in-build FTP you need to combine the FTP host header in the FTP username e.g. www.hello.com|domain/username So, the FTP program gets its "hook" from the username. However, you can connect to the FTP site using www.hello.com:21 over the FTP port. Why then, doesnt the FTP service work the same way as the HTTP service? IIS knows what site to serve back based on the host header after all.... Thanks!

• What causes "All-in-one USB Card Reader" to create 6 drives that always appear in Disk Management?

  - by tim11g

  I installed a "All-in-one USB Card Reader" to read SD cards and other media. It has caused six new drives to appear in Disk Management with six new drive letter assignments. These drives and letters are always present, even when there are no cards in the reader. When unused, they are labeled "No Media". Why does this multifunction reader cause these phantom Disks to appear and consume drive letters? Every USB port can (and does) allow removable media to be mounted and assigned a drive letter, and the drive letter assignment "disappears" when the USB drive is removed. Why are these card reader's drives and letters staying allocated permanently? Is there anything that can be done to make the slots work like a typical USB drive? (The reader is in fact connected to USB).

• Tomcat and IIS6 on one server, multiple websites

  - by Rafe

  Windows Server 2003 with IIS6 and Tomcat 6.0.26. Three sites running on this server. One is PHP, one is ASP and the third uses Tomcat. The first two work flawlessly. The third is being a pain. Tomcat is installed and if called on the server itself by IP address xxx.xxx.xxx.xxx:8080 shows the welcome page. Calling the same address from an external machine gives a 'could not connect' error. Calling the ip address from within the server on standard port 80 gives me an error 324 (net::ERR_EMPTY_RESPONSE). Have tried using httpcfg to force listening only on ports within the ip range I'm using in a manner similar to question 35650 located here on serverfault but with no success. There are actually ten ip addresses on this machine but I'm only using three of them at this point. Any pointers on troubleshooting this would be appreciated!

• Unable to make my bios see my sata hdd

  - by Stefan

  I know there are many question about that, but I tried everything and I'm still not able to make my bios see my sata2 hdd. I've got a QDI motherbord with no sata port; only 2 ide ports. I had an old ide hdd, now i've removed it and bought a sata2 hdd. Since my pc has no sata slots i bouth a ide-to-sata adapter. So, i don't have any os installed on the new drive, and the old drive is removed. My problem is that I'm unable to see my hdd on bios. I suppose that my bios, since it's an old version, doesn't have sata drivers, but I don't know if I must install it and also I dont know how to do it. Anyone can help me?

• Creating self-signed SSL on IIS - Remote access problem

  - by ile

  I followed these instructions to create self-signed ssl: http://www.visualwin.com/SelfSSL/ (I opened SelfSSL and typed selfssl /T) When I access https: //localhost/ than it works, but when I try to access it remotely (i set up my router to port forward to localhost), for example https: //myip the page does not load. Also, I noticed one other thing. When I access localhost locally then I am asked to enter user/pass, but if I access remotely the I get the following warning: Under Construction The site you were trying to reach does not currently have a default page. It may be in the process of being upgraded and configured. ... I don't know if it is related with this but I hope someone know the answer. Thanks, Ile

• Sharing a printer over the net from Windows 7 to Windows Server 2003

  - by Grant Unwin

  Hi, I need to share a printer that is connected to a Windows 7 computer. The windows 7 computer is in another building about an hours drive away. The computer that needs to access the printer is running Windows Server 2008. Ive tried setting the printer as 'shared' for 'everyone' on the Windows 7 PC and accessing it from the server by adding a TCP/IP port to the IP address but the printer just wont add. From googling aparently it may need setting up as a printer server through IIS, but i'm just not sure on the best practice. Any help greatly appreciated. Thanks Grant Unwin

• Httpd restart "Address already in use" error

  I have an .rpm, which I created. In its %post part, I do some stuff, and in the end of this script, i call service httpd restart. It gives the following error: + service httpd restart Stopping httpd: [FAILED] Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:81 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:81 no listening sockets available, shutting down Unable to open logs [FAILED] I got this from the rpm verbose installing (-vv). So I know its about httpd restart itself, nothing else. The according to netstat only one process (httpd) is listening on port 81. $ sudo netstat -nlp | grep 81 tcp 0 0 :::81 :::* LISTEN 29670/httpd I don't understand, why running http FAILS at stop, and FAILS again in start. Any ideas how to solve this?

• How do I set up a shared internet on a network using computer hooked up to a router

  - by Skadlig

  I got a wireless broadband modem (Huawei E1750) hooked up to my computer (call it A., running Windows-7) whose internet I wish to share to my other computer (call it B., also running Windows-7). A. is hooked up to my d-link DIR-600 router using a wired connection to port 1 on the router. B. is connected to the router using a wireless connection. Now I have tried setting up the sharing according to the help files for ICS but I have not been able to get it working. I suspect that there is something in my hardware configuration that is making it difficult. I would appreciate some tips and pointers as to what could be the reason to my problems.

Also, I want to set up 2 virtual Servers with 2008 R2 standart one with SQL Server and the other with Team Foundation. What i need is: Being able to access from inside the private phisical network, to Remote Desktops on each of the Virtual and the phisical Servers Had Access from the outside, using a router and port Forwarding, to the TFS server and the IIS server (one is virtualized, the other is phisical) This is it, but note that I only have one Phisical Nic. How do I configure this to work. When i set up the hyper-v role, on the wizard something like it showed up but I don't remmember what i choose, and right now, I cannot access none of the servers from remote desktop, not even from the phisical private network. Can anybody point me, what can i do? Thanks in advance (sorry 4 my english, i'm a spanish talker and my english isn't that good)

• Exchange 2010 periodically stops responding to SMTP events with error 421 4.4.1 Connection timed out

  - by Michael Shimmins

  After some help diagnosing why Exchange 2010 Enterprise stops responding to SMTP events. I can't find a pattern to it. It doesn't appear to be an actual timeout, as the server responds immediately with the error. To reproduce it I telnet into the server on port 25 and issue a EHLO. The server immediately replies with the 421: 421 4.4.1 Connection timed out Once this starts happening I've found restarting the exchange box is the only reliable way to get it flowing again. Sometimes restarting the Transport service or the mailbox attendant service seems to fix it, but this could be coincidental as it often has no effect.

• How to use IIS as a trusted proxy for ActiveDirectory SSO?

  - by brofield

  I'm trying to add Active Directory single-sign-on support to an existing SOAP server. The server can be configured to accept a trusted reverse-proxy and use the X-Remote-User HTTP header for the authenticated user. I want to configure IIS to be the trusted proxy for this service, so that it handles all of the Active Directory authentication for the SOAP server. Basically IIS would have to accept HTTP connections on port X and URL Y, do all the authentication, and then proxy the connection to a different server (most likely the same X and Y). Unfortunately, I have no knowledge of IIS or AD (so I am trying my best to learn enough to build this solution) so please be gentle. I would assume that this is not an uncommon scenario, so is there some easy way to do this? Is this sort of functionality built into IIS or do I need to build some sort of IIS proxy program myself? Is there a better option for getting the authentication done and the X-Remote-User HTTP header set than requiring IIS?

Thanks in advance :) Oh, here is the output from the log file /var/named/data/named.run when I perform the reverse lookup: quan@quantran:~$ host 192.168.56.102 192.168.56.101 Using domain server: Name: 192.168.56.101 Address: 192.168.56.101#53 Aliases: Host 102.56.168.192.in-addr.arpa not found: 2(SERVFAIL) /var/named/data/named.run: 02-Jun-2014 15:18:11.950 client: debug 3: client 192.168.56.1#51786: UDP request 02-Jun-2014 15:18:11.950 client: debug 5: client 192.168.56.1#51786: using view '_default' 02-Jun-2014 15:18:11.950 security: debug 3: client 192.168.56.1#51786: request is not signed 02-Jun-2014 15:18:11.950 security: debug 3: client 192.168.56.1#51786: recursion available 02-Jun-2014 15:18:11.950 client: debug 3: client 192.168.56.1#51786: query 02-Jun-2014 15:18:11.950 client: debug 10: client 192.168.56.1#51786: ns_client_attach: ref = 1 02-Jun-2014 15:18:11.950 query-errors: debug 1: client 192.168.56.1#51786: query failed (SERVFAIL) for 102.56.168.192.in-addr.arpa/IN/PTR at query.c:5428 02-Jun-2014 15:18:11.950 client: debug 3: client 192.168.56.1#51786: error 02-Jun-2014 15:18:11.950 client: debug 3: client 192.168.56.1#51786: send 02-Jun-2014 15:18:11.950 client: debug 3: client 192.168.56.1#51786: sendto 02-Jun-2014 15:18:11.951 client: debug 3: client 192.168.56.1#51786: senddone 02-Jun-2014 15:18:11.951 client: debug 3: client 192.168.56.1#51786: next 02-Jun-2014 15:18:11.951 client: debug 10: client 192.168.56.1#51786: ns_client_detach: ref = 0 02-Jun-2014 15:18:11.951 client: debug 3: client 192.168.56.1#51786: endrequest 02-Jun-2014 15:18:11.951 client: debug 3: client @0xb537e008: udprecv Also, I made some changes to the log section in named.conf.

• TCP failure on Solaris

  - by anurag kohli

  Hi All, I recently ran into a problem where a Solaris server could not establish a TCP socket on port 2126. From a packet capture I see this (note: A is a Solaris server, B is a router): A sends SYN to B B sends SYN, ACK to A Notice A (Solaris) does not acknowledge the SYN from B. Due to the business impact of the problem, I had to reboot the server to fix the problem. That said, I want to know the next time the problem occurs, what can I do to get a root cause (ie before server reboot)? Thanks in advance.
