  • tcp msl timeout

    - by iamrohitbanga
    The following is given in the book TCP IP Illustrated by Stevens Quiet Time Concept The 2MSL wait provides protection against delayed segments from an earlier incarnation of a connection from being interpreted as part of a new connection that uses the same local and foreign IP addresses and port numbers. But this works only if a host with connections in the 2MSL wait does not crash. What if a host with ports in the 2MSL wait crashes, reboots within MSL seconds, and immediately establishes new connections using the same local and foreign IP addresses and port numbers corresponding to the local ports that were in the 2MSL wait before the crash? In this scenario, delayed segments from the connections that existed before the crash can be misinterpreted as belonging to the new connections created after the reboot. This can happen regardless of how the initial sequence number is chosen after the reboot. To protect against this scenario, RFC 793 states that TCP should not create any connections for MSL seconds after rebooting. This is called the quiet time Few implementations abide by this since most hosts take longer than MSL seconds to reboot after a crash. Do operating systems wait for 2MSL seconds now after a reboot before initiating a TCP connection. The boot times are also less these days. Although the ports and sequence numbers are random but is this wait implemented in Linux?

  • How do I get the F1-F12 keys to switch screens in gnu screen in cygwin when connecting via SSH?

    - by Mikey
    I'm connecting to a desktop running cygwin via SSH from the terminal app in Mac OS X. I have already started screen on the cygwin side and can connect to it over the SSH session. Furthermore, I have the following in the .screenrc file: bindkey -k k1 select 1 # F1 = screen 1 bindkey -k k2 select 2 # F2 = screen 2 bindkey -k k3 select 3 # F3 = screen 3 bindkey -k k4 select 4 # F4 = screen 4 bindkey -k k5 select 5 # F5 = screen 5 bindkey -k k6 select 6 # F6 = screen 6 bindkey -k k7 select 7 # F7 = screen 7 bindkey -k k8 select 8 # F8 = screen 8 bindkey -k k9 select 9 # F9 = screen 9 bindkey -k F1 prev # F11 = prev bindkey -k F2 next # F12 = next However, when I start multiple windows in screen and attempt to switch between them via the function keys, all I get is a beep. I have tried various settings for $TERM (e.g. ansi, cygwin, xterm-color, vt100) and they don't really seem to affect anything. I have verified that the terminal app is in fact sending the escape sequence for the function key that I'm expecting and that my bash shell (running inside screen) is receiving it. For example, for F1, it sends the following (hexdump is a perl script I wrote that takes STDIN in binmode and outputs it as a hexadecimal/ascii dump): % hexdump [press F1 and then hit ^D to terminate input] 00000000: 1b4f50 .OP If things were working correctly, I don't think bash should receive the escape sequence because screen should have caught it and turned it into a command. How do I get the function keys to work?

  • Windows XP Boot Issue - Diagnosing A Hard Drive Failure

    - by duffymo
    My five-year-old HP desktop running Windows XP SP3 wouldn't boot from the hard drive yesterday afternoon. I would see the boot sequence begin, then nothing but a black screen. Fortunately, I had just done an Acronis backup to my external drive in the morning, and I have a bootable USB key. I put the USB key into the drive, powered up the machine, and put the USB key first in line in the boot sequence. Voila! My machine came alive. But now I'm confused as to what the problem is and what to do next. I assumed that my hard drive was toast. But now that the machine is alive I can see files on my C: drive that have changes I made just yesterday. Clearly the drive is not dead. Here are my questions: What could explain my inability to boot from the hard drive? What would a remedy be? What's my best course of action? Should I replace the hard drive with a new one? If I replace the hard drive, do I reinstall the OS and apply the backup I did yesterday? If I decide that re-installing Windows XP makes no sense, how do I get back the Acronis backup that I did yesterday? I don't want to lose that. UPDATE: I just learned one more key fact. I'm having some work done on my house. I neglected to shut my machine down before the contractor came. My wife said he shut down the power to do some work on a circuit and then powered the house back up. I have a surge protector, but is it possible that cycling the power did some damage?

  • MAMP MySQL won't start

    I uninstalled MAMP completely, downloaded fresh copy of MAMP 2 from the MAMP website, did a clean install. However, when I try to start mysql, I get the following error log 111120 21:37:49 mysqld_safe Starting mysqld daemon with databases from /Applications/MAMP/db/mysql 111120 21:37:50 [Warning] You have forced lower_case_table_names to 0 through a command-line option, even though your file system '/Applications/MAMP/db/mysql/' is case insensitive.

I googled around and made sure that no instance of MySQL is running. Nothing seems to help.

  • VMWare steals IP addresses

    - by Ishan Amin
    I'm having a peculiar problem, that I think I have narrowed down to VMware. For the past one year, every once in a while we lose internet connection and not all users (about 10 users) go down at the same time, its usually one-by-one. First someone will call me and say "Internet is down" and then we would go reset the router and modem and switch and it would be working again for a while, then go down again without any pattern or replicatable sequence. We'd go repeat the steps again to get everyone in the office running again. We called our Internet Service Provider and they constantly say, We see your modem and we see your router and from thier end everything is OK. we replaced our router and switch and modem, twice! Last friday, it dawned upon me, that everytime we turn on a VMware machine, this sequence of taking everyone down starts, which also explains the message that my users get for "IP Conflict Found" So we do alot of VMware testing and lo and behold, it takes my Internet down. My Yahoo and Gtalk would continue working but www is down when the VMware machines are started. I do use bridged networking to all the VMware machines, but I dont know what else to set it at. now, sorry for this long rambling but anyone have any clue on how to stop this? thanks IA

  • mysqld crashes on any statement

    - by ??iu
    I restarted my slave to change configuration settings to skip reverse hostname lookup on connecting and to enable the slow query log. I edited /etc/my.cnf making only these changes, then restarted mysqld with /etc/init.d/mysql restart All appeared to be well but when I connect to msyqld remotely or locally though it connects okay a slight problem is that mysqld crashes whenever you try to issue any kind of statement.

Activity monitor gives me a mysqld process running by me, and everytime i KILL the process both via Activity Monitor and via kill =9 pid it starts right back up.. Sampling the process points back to the MAMP mysqld.. wtf?! About to throw MAMP out the window and boot up a VM of CentOS =)

  • What XMonad Configuration Best Replicates Default Ion3 Behavior and Feature Set?

    - by mtp
    Not being very familiar with Haskell and lamenting that Ion 3 is now abandonware, I am curious if anyone out there has found a way of replicating the default Ion 3 behavior and aesthetics in XMonad. If I can't have a near-exact replica of Ion 3-style behavior in XMonad, here is what would be critical to me: Virtual desktops that are empty by default and that spawn full-screen applications, which can be split horizontally or vertically evenly, leaving an empty adjacent pane. The panes, which house open windows, are manually resizable, preferably via keyboard. The panes exhibit tabbed behavior, meaning that they can house multiple windows. Windows can be tagged and moved between panes / virtual desktops via keyboard sequence. A given window may be temporarily exploded into full-screen mode via keyboard sequence. Each new virtual desktop starts in the same state—i.e., with one pane. Each virtual desktop may have its panes divided independently of other virtual desktops. From my investigation, it appears that there are several configurations that provide #3. For as much as I want to spend the time to familiarize myself with Haskell, I just simply don't have time. Any suggestions would be greatly appreciated. As far as I can tell, Ion has no conception of master pane or window, so this behavior is not desired.

  • Cannot destroy ZFS snapshot: dataset already exists

    - by Morven
    I have a server (T5220, though I doubt it matters) running Solaris 10 8/07 and I have a ZFS pool, "mysql", on internal disk. Within it I have a filesystem "mysql/data/4.1.12", which I snapshot hourly with a script from cron. I have one snapshot, created as one of those hourly snaps, that will not destroy. I have renamed it out of sequence to be "mysql/data/4.1.12@wibble" so that my script will not try and fail to destroy it, but it was originally within the sequence, though I doubt that matters. It renames successfully. The snapshot can be successfully navigated and read from through the .zfs/snapshots directory. It has no clones based on it. Trying to destroy it does this: (265) root@web-mysql4:/# zfs destroy mysql/data/4.1.12@wibble cannot destroy 'mysql/data/4.1.12@wibble': dataset already exists (266) root@web-mysql4:/# which is apparently nonsensical: of course it already exists, that's the point! Anyone seen anything like this before? Web searches show nothing obviously similar. I can provide patches installed if necessary.

  • Apache and MySQL not working well after extending filesystem

    - by xtrimsky
    I had 4Gb on my /var (/dev/mapper/vg00-var) filesystem, and I wanted to extend it to 160Gb. I did it following this tutorial: http://faq.1and1.com/dedicated_servers/root_server/linux_admin_help/7.html Now I have 160: Filesystem Size Used Avail Use% Mounted on /dev/md1 4.0G 424M 3.6G 11% / /dev/mapper/vg00-usr 4.3G 1.4G 3.0G 32% /usr /dev/mapper/vg00-var 198G 6.5G 192G 4% /var /dev/mapper/vg00-home 4.3G 4.4M 4.3G 1% /home none 1.1G 0 1.1G 0% /tmp Now I have a problem, in order for Apache to work, each time I reboot, I need to also reboot apache: "apachectl -k restart" which is already terrible. I think this is because /var contains the htdocs The worst part is, mysql is not starting at all. Mysql has some files also in /var What have I done wrong ?? :( Thank you EDIT: Attaching /var/log/mysqld.log: 120602 11:17:44 InnoDB: Waiting for the background threads to start 120602 11:17:45 InnoDB: 1.1.8 started; log sequence number 8354009 120602 11:17:45 [ERROR] /usr/libexec/mysqld: unknown variable 'set-variable=local-infile=0' 120602 11:17:45 [ERROR] Aborting 120602 11:17:45 InnoDB: Starting shutdown... 120602 11:17:46 InnoDB: Shutdown completed; log sequence number 8354009 120602 11:17:46 [Note] /usr/libexec/mysqld: Shutdown complete 120602 11:17:46 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

  • Are there any lightweight alternatives to gSOAP?

    - by che
    I've tried using gSOAP for accessing a web service (e.g. using supplied WSDL to generate C stubs and then using them in an app). However, I've found that the generated .c and object files is quite big (several megabytes), which is a problem in embedded environment where I work. Do you know of any simpler SOAP libraries, or do I have to fall back to generic XML generators and parsers like ezXML?

  • Finding Freelance/Contract Coding Projects

    - by Laplie
    What's the best way to find freelance/contract coding projects? I'm looking for paid freelance coding jobs. Almost all of the websites that I've come across are filled with foreigners willing to work at 1/4th the pay, job posters wanting you to recode Microsoft Office for $50, or grey-area coding projects (link generators, bots, trojans). Is there any way to find decent freelance work?

  • Installing RESTful Authentication on netbeans

    - by Kerwin
    Hi I am using Netbeans 6.8 on ubuntu 10.04 and am having trouble installing RESTful Authentication. I have gone to Install Generators, selected restful_authentication and installed it - all messages from Gem show that it has installed and it shows under the Installed tab. However, when I come to use it by clicking on the Generator drop down there is no sign of it. I beleive ther should be a selection saying "authenticated".

  • lexers vs parsers

    - by Naveen
    Are lexers and parsers really that different in theory ? It seems fashionable to hate regular expressions: coding horror, another blog post. However, popular lexing based tools: pygments, geshi, or prettify, all use regular expressions. They seem to lex anything... When is lexing enough, when do you need EBNF ? Has anyone used the tokens produced by these lexers with bison or antlr parser generators?

  • What are the Ruby equivalent of Python itertools, esp. combinations/permutations/groupby?

    - by Amadeus
    Python's itertools module provides a lots of goodies with respect to processing an iterable/iterator by use of generators. For example, permutations(range(3)) --> 012 021 102 120 201 210 combinations('ABCD', 2) --> AB AC AD BC BD CD [list(g) for k, g in groupby('AAAABBBCCD')] --> AAAA BBB CC D What are the equivalent in Ruby? By equivalent, I mean fast and memory efficient (Python's itertools module is written in C).
