• How switch between screen inside screen?

  - by André Andrade

  I have to work inside two environment. One Windows (local) and one Linux (remote). I've installed the screen linux utility in both. I'm able to open a screen on my windows, then in one tab, I opened a ssh connection to the linux remote and I start another screen. Sample linux -- |0 linux remote 0| 1 linux remote 1 windows-- |0 linux | 9 windows I can switch between "linux remote 0" and "linux remote 1" using Atl+. This is configured in .screenrc (bindkey "^[0" select 0) How could I switch to "9 windows"?

• Oracle moves to Java technology to embedded middleware

  - by hinkmond

  Here's another article pointing out our move to Java Embedded Middleware with our launch of Oracle Java Embedded Suite 7.0 See: Oracle moves to Java embedded middleware Here's a quote: At the JavaOne Embedded conference, a wafer thin embedded device that was smaller than a Ritz cracker was loaded up with the Java Embedded Suite. I like that: "a wafer thin embedded device". Just one thin wafer. Reminds me of the scene from Monty Python's, The Meaning of Life. "Better?" Hinkmond

• mmap only needed pages of kernel buffer to user space

  - by axeoth

  See also this answer: http://stackoverflow.com/a/10770582/1284631 I need something similar, but without having to allocate a buffer: the buffer is large, in theory, but the user space program only needs to access some parts of it (it mocks some registers of a hardware). As I cannot allocate with vmalloc_user() such a large buffer (kernel 32 bit, in embedded environment, no swap...), I followed the same approach as in the quoted answer, trying to allocate only those pages that are really requested by the user space. So: I use a my_mmap() function for the device file (actually, is the .mmap field of a struct uio_info) to set up the fields of the vma, then, in the vm_area_struct's .fault field (also named my_fault()), I should return a page. except that: In the my_fault() method of vm_area_struct, I cannot obtain a page through: vmf->page=vmalloc_to_page(my_buf + (vmf->pgoff << PAGE_SHIFT)); since there is no allocated buffer: my_buf = vmalloc_user(MY_BUF_SIZE); fails with "allocation failed: out of vmalloc space - use vmalloc= to increase size." (and there is no room or swap to increase that vmalloc= parameter). So, I would need to get a page from the kernel and fill the vmf->page field. How to allocate a page (I assume that the offset of the page is known, as it is vm->pgoff). What base memory should I use instead of my_buf? PS: I also did set up the vma->flags |= VM_NORESERVE; (in the my_mmap()), but not sure if it helps. Is there any vmalloc_user_unreserved()-like function? (let's say, lazy allocation) Also, writing 1 to /proc/sys/vm/overcommit_memory and large values (eg 500) to /proc/sys/vm/overcommit_ratio before trying to my_buf=vmalloc_user(<large_size>) didn't work.

• Linux network stack : adding protocols with an LKM and dev_add_pack

  - by agent0range

  Hello, I have recently been trying to familiarize myself with the Linux Networking stack and device drivers (have both similarly named O'Reilly books) with the eventual goal of offloading UDP. I have already implemented UDP on the NIC but now the hard part... Rather than ask for assistance on this larger goal I was hoping someone could clarify for me a particular snippet I found that is part of a LKM which registeres a new protocol (OTP) that acts as a filter between the device driver and network stack. http://www.phrack.org/archives/55/p55_0x0c_Building%20Into%20The%20Linux%20Network%20Layer_by_lifeline%20&%20kossak.txt (Note: this Phrack article contains three different modules, code for the OTP is at the bottom of the page) In the init function of his example he has: otp_proto.type = htons(ETH_P_ALL); otp_proto.func = otp_func; dev_add_pack(&otp_proto); which (if I understand correctly) should register otp_proto as a packet sniffer and put it into the ptype_all data structure. My question is about the dev_add_pack. Is it the case that the protocol being registered as a filter will always be placed at this layer between L2 and the device driver? Or, for instance could I make such a filtering occur between the application and transport layers (analyze socket parameters) using the same process? I apologize if this is confusing - I am having some trouble wrapping my head around the bigger picture when it comes to modules altering kernel stack functionality. Thanks

• Fake serial communication under Linux

  - by kigurai

  I have an application where I want to simulate the connection between a device and a "modem". The device will be connected to a serial port and will talk to the software modem through that. For testing purposes I want to be able to use a mock software device to test send and receive data. Example Python code device = Device() modem = Modem() device.connect(modem) device.write("Hello") modem_reply = device.read() Now, in my final app I will just pass /dev/ttyS1 or COM1 or whatever for the application to use. But how can I do this in software? I am running Linux and application is written in Python. I have tried making a FIFO (mkfifo ~/my_fifo) and that does work, but then I'll need one FIFO for writing and one for reading. What I want is to open ~/my_fake_serial_port and read and write to that. I have also lpayed with the ptymodule, but can't get that to work either. I can get a master and slave file descriptor from pty.openpty() but trying to read or write to them only causes IOError Bad File Descriptor error message.

• linux raw socket programming question

  - by user194420

  Hi all, I am trying to create a raw socket which send and receive message with ip/tcp header under linux. I can successfully binds to a port and receive tcp message(ie:syn) However, the message seems to be handled by the os, but not mine. I am just a reader of it(like wireshark). My raw socket binds to port 8888, and then i try to telnet to that port . In wireshark, it shows that the port 8888 reply a "rst ack" when it receive the "syn" request. In my program, it shows that it receive a new message and it doesnot reply with any message. Any way to actually binds to that port?(prevent os handle it) Here is part of my code, i try to cut those error checking for easy reading sockfd = socket(AF_INET, SOCK_RAW, IPPROTO_TCP); int tmp = 1; const int *val = &tmp; setsockopt (sockfd, IPPROTO_IP, IP_HDRINCL, val, sizeof (tmp)); servaddr.sin_family = AF_INET; servaddr.sin_addr.s_addr = htonl(INADDR_ANY); servaddr.sin_port = htons(8888); bind(sockfd, (struct sockaddr*)&servaddr, sizeof(servaddr)); //call recv in loop

• In Technology, Ignorance is NOT Bliss

  - by Tanu Sood

  Author: Debra Lilley, ACE Director, UK Proof I’m not technical -  I’ve just finished a Latin America tour with OTN and a funny thing happened that I want to share with you; because it is quite a good analogy for how many of us use technology today and you know how I love analogies. In Costa Rica we had a really long journey up through the mountains to where our conference was to be. The road was windy and narrow and once it got dark there was no scenery to see, boredom set in. At one stage I looked at my watch to see the time, but in the dark I couldn’t make it out, so I thought I would be clever and use the torch in my smartphone! Even though as soon as I switched on the phone it showed the time, I ignored it and used the torch to read my watch. That’s us when we pay maintenance on software, ask for enhancements, and either chose not to upgrade or as I have seen so many times, upgrade but don’t use the new features. I know there are always other factors not least the upgrade costs themselves but in the later releases of all the Oracle family of applications Oracle have done a lot to make the interoperability of them with Oracle Fusion Middleware more successful and in many cases for the first time. My heritage is Oracle E Business Suite (EBS) and the availability of Oracle Weblogic for EBS is fantastic for an Oracle powered organisation that can move away from supporting multiple flavours of application server. The same release made available  - the no downtime patching that Oracle Database 11g introduced with Edition Based Redefinition. I am not saying you must use these features but you must be aware of what each release of your application brings and make a business based decision as to whether it is for you or not. I like to have a simple spreadsheet of features with no-value, nice-to-have, must-have ratings, but make the spreadsheet cumulative so that when you do upgrade you have all the features listed you previously didn’t take up. That way you can avoid the ‘using your phone to read your watch’ scenario. About the Author: Debra Lilley, Fusion Champion, UKOUG Board Member, Fusion User Experience Advocate and ACE Director. Lilley has 18 years experience with Oracle Applications, with E Business Suite since 9.4.1, moving to Business Intelligence Team Lead and Oracle Alliance Director. She has spoken at over 100 conferences worldwide and posts at debrasoraclethoughts

• READ_ME_FIRST: What Do I Do All of Those SPARC Threads?

  - by user12608550

  New Oracle Technical White Paper: READ_ME_FIRST: What Do I Do All of Those SPARC Threads? Executive Overview With an amazing 1,536 threads in an Oracle M5-32 system, the number of threads in a single system has never been so high. This offers a tremendous processing capacity, but one may wonder how to make optimal use of all these resources. In this technical white paper, we explain how the heavily threaded Oracle T5 and M5 servers can be deployed to efficiently consolidate and manage workloads using virtualization through Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle Enterprise Manager Ops Center, as well as how to improve the performance of a single application through multi-threading.

• Is memory allocation in linux non-blocking?

  - by Mark

  I am curious to know if the allocating memory using a default new operator is a non-blocking operation. e.g. struct Node { int a,b; }; ... Node foo = new Node(); If multiple threads tried to create a new Node and if one of them was suspended by the OS in the middle of allocation, would it block other threads from making progress? The reason why I ask is because I had a concurrent data structure that created new nodes. I then modified the algorithm to recycle the nodes. The throughput performance of the two algorithms was virtually identical on a 24 core machine. However, I then created an interference program that ran on all the system cores in order to create as much OS pre-emption as possible. The throughput performance of the algorithm that created new nodes decreased by a factor of 5 relative the the algorithm that recycled nodes. I'm curious to know why this would occur. Thanks. *Edit : pointing me to the code for the c++ memory allocator for linux would be helpful as well. I tried looking before posting this question, but had trouble finding it.

• Perl like regular expression in Oracle DB
