How to enable ICMP ECHO but still protect against ICMP DoS attacks? [WAS: Are ICMP packets not important for a hosted machine?]
Follow up question: ICMP can be used for DoS. Cool. How does google battle with that? All google services are ping'able (which is very cool obviously). How do they protect against the attack?, surly there are enough script kiddies that constantly try to DoS Google. 2010/10/19 shimi linux...@shimi.net See inline, On Tue, Oct 19, 2010 at 7:23 PM, Ron Varburg linux...@hotmail.com wrote: A Hosting service is blocking pings from the Internet to the hosted servers. It is possible to ping from the hosted servers to anywhere on the Internet, assuming that the packets are not dropped somewhere else, ofcourse. 1. Why would the hosting service bother with such a blockage? Mitigating some of a Denial Of Service attack. If a machine replies to ICMP Echo DoS attack, it doubles the amount of traffic it has to handle. Since blocking ICMP Echo has no actual effect on any other thing beside of checking if a machine is alive, they believe the benefit of not participating in a DoS attack outweights the lack of ability to ping-test the machine. (not to mention that it may be filtering just *some* of the ICMP Echo packets, and may be responding to ICMP Echo if sent from a limited set of IPs (for example a monitoring machine and/or the sysadmin's IP pool...) 2. Is it reasonable to assume that more ICMP packets are blocked? Yes, many people block ICMP alltogether, not realizing that ICMP Echo and ICMP Echo Reply are not the only type of ICMP messages, and just block any IP packet that has ICMP in it. 3. What are the implications of such a blockage? In particular, assuming that each hop in a random path takes care to assure connectivity to any nearest hop, one might think that ICMP packets are not important and hardly used. The annoying ones: PMTU[1] breaks. If any router / medium in the middle cannot support the client/server MTU (typically - 1500), and a packet with the DF[2] flag is sent, it will be dropped silently and the sender wouldn't know, and re-transmit the packet until the connection times out and dies. The less annoying but non-too-interfering: If a router on the way filters the packet due to some policy, or that some router on the way has a dead link for the next hop, no ICMP notifying that the host/net is unreachable will reach the client; Instead of immediately knowing that it can't connect (and with a pretty good explanation on why), the client would simply try to re-send a SYN packet over and over again, until it gets into timeout state.

I'd like to add that I have been a satisfied customer of Amazon for over a year, using their services for both consulting at at my current job where we use it to run our SaaS offering. The capabilities keep improving and the prices keep coming down. Their lowest end server is now just 2 cents an hour! There are some issues with the IO, but it is certainly adequate for all but high performance needs. We use 8 way stripped disks and get about 100 MBp/s sequential reads. If anyone wants more details, I'll be happy to share with you. -tom I am considering using EC2 for a web application. I am not sure how to calculate the payment per month. Do I pay only for the time someone makes a request? For example, I have a user who requests a certain report and it takes 1 second to load the report request form, then 20 seconds to produce the report and print it. I understand that I pay for 21 seconds? In addition to mistakes already corrected, there is another mistake of how long something takes. Amazon aim to provide a certain computation power unit, but benchmarks show that what is actually provided has high variability. For example, ping times to EC2 machines started rising significantly since Amazon announces the spot instances. See also: Some more input on EC2. Not all instances born alike. We recently ran a huge computation based on Hadoop and you can definitely see that some nodes perform faster (I/O was the bottleneck) then others. I too, when starting with EC2 made the mistake to of thinking that you only pay for as much CPU as you use. Wrong! OTOH, I was very happy to find out that with Google AppEngine this is actually the case: You pay for as much resources as you consume. And they DO count CPU Time vs. Amazon's instance is running time. Another note regarding EC2. Read bitbucket story about ec2 horrors http://blog.bitbucket.org/. Yet please don't get me wrong, generally EC2, S3, CloudFront, ELB and other Amazon's services work great - Our production farm (~40 servers is hosted there and we are relatively happy). Amazon's main issues are: I/O bandwidth is funny Occasionally peaks in connectivity time that lead to timeouts (between zones from the outside world). Not so fair hypervisor: We've seen occasions when an instance slows down for a couple of minutes. We assume (without being able to tell for sure) that some bigger instance type that happen to be hosted on the same physical server as we are got resource hungry and practically ate all our CPU time...

I'd like to add that I have been a satisfied customer of Amazon for over a year, using their services for both consulting at at my current job where we use it to run our SaaS offering. The capabilities keep improving and the prices keep coming down. Their lowest end server is now just 2 cents an hour! There are some issues with the IO, but it is certainly adequate for all but high performance needs. We use 8 way stripped disks and get about 100 MBp/s sequential reads. If anyone wants more details, I'll be happy to share with you. -tom I am considering using EC2 for a web application. I am not sure how to calculate the payment per month. Do I pay only for the time someone makes a request? For example, I have a user who requests a certain report and it takes 1 second to load the report request form, then 20 seconds to produce the report and print it. I understand that I pay for 21 seconds? In addition to mistakes already corrected, there is another mistake of how long something takes. Amazon aim to provide a certain computation power unit, but benchmarks show that what is actually provided has high variability. For example, ping times to EC2 machines started rising significantly since Amazon announces the spot instances. See also: Some more input on EC2. Not all instances born alike. We recently ran a huge computation based on Hadoop and you can definitely see that some nodes perform faster (I/O was the bottleneck) then others. I too, when starting with EC2 made the mistake to of thinking that you only pay for as much CPU as you use. Wrong! OTOH, I was very happy to find out that with Google AppEngine this is actually the case: You pay for as much resources as you consume. And they DO count CPU Time vs. Amazon's instance is running time. Another note regarding EC2. Read bitbucket story about ec2 horrors http://blog.bitbucket.org/. Yet please don't get me wrong, generally EC2, S3, CloudFront, ELB and other Amazon's services work great - Our production farm (~40 servers is hosted there and we are relatively happy). Amazon's main issues are: I/O bandwidth is funny Occasionally peaks in connectivity time that lead to timeouts (between zones from the outside world). Not so fair hypervisor: We've seen occasions when an instance slows down for a couple of minutes. We assume (without being able to tell for sure) that some bigger instance type that happen to be hosted on the same physical server as we are got resource hungry and practically ate all our CPU time...

Unencrypted the speed was around 5k/s, encrypted less than 1k/s. worse than that I tried tunneling via a good site (speed guaranteed) and even this didn't work well. Transfer from israel has excellent speed. Other than that, nothing. My conclusion is that they started to apply QOS and other dirty tricks which I noticed via wireshark. I would suggest few things: 1. try to download the same rpm from other sites and compare. and then call them and show them it's impossible to get such low speed from 4-5 different sites. 2. In cases where you can change ports, try to revert to high end ports. 3. Try https. Maybe you will get lucky.

This is implemented as a C program with sockets interface, so find a button actually means look for a substring in the received HTML code and press the button means create an HTTP POST message and send it. However, recently we have added some JavaScript and AJAX to the web-interface and now the testing environment must be able to run JS and even cope with things like replacing part of the DOM tree. We can see three possible directions to tackle the problem: - Further fix our great testing program. After all, we know what AJAX can return -- we can manually open the connection it would open, parse the response, etc. Looks ugly and has a potential to turn into maintenance nightmare. - Setup a headless X server with Firefox running inside and some sort of scripting/management add-on. If someone has an experience with such a setup, I would appreciate pointers to specific add-ons you used. - Somehow hack off the GUI from any open-source browser and link it to our program, i.e. use it as HTML parser and JS machine.

have family coming from the US and force them to bring the books to me here.
I keep saying there must be a better way to get good books here in Israel.
Is there a bookstore somewhere that already imports these kinds of books, or
that can order them for me and deliver them to me via IL Post or where I can
pick them up somewhere local in this part of the country?
I have ordered books through a previous employer from Amazon.co.uk, but I
remember it being much more expensive than getting them in the US. What are
your experiences. Thank you.
How about purchasing a Kindle and then ordering nothing but electronic books?
I seems that in the long run it might turn out to be more beneficial
then buying batches of printed books.

Color highlighting of arbitrary tail -F'ed text ?
Hi, Someone has a good recommendation for a log syntax highlighter ? I have my application logs where I need to quickly highlight some text, in that case name= the output is verbose as I'm running in TRACE. Could some one please suggest a suitable tool as I've tried some project but the hardly work. Thank you, Maxim. -- Cheers, Maxim Veksler Free as in Freedom - Do u GNU ?

If it's formatted ( or would be since it's your application ):
1. Add relevant syntax for vt100 terminal or the likes and display the
output on such a terminal ( dah.. )
2. Import into a spreadsheet.
3. For large amounts of data, import into a db, postgres or whatever.
Hmmm, well no. I mean more as a tool I would use for debugging during
development. Something that would allow me to do :
tail -F /var/log/MyApp/DCN.log | SuperSyntaxHighlighter
-SearchForWord=^regexOrSomething -SearchForWordColor=#FF
I need something would allow me to highlight arbitrary terms in the
log. Now I'm searching for Name tomorrow I might be search for
objectId. I need a quick and dirty solution. Thank you ;)

Replace {1} by regular expression which matches the part you want to
highlight in addition to the name=, maybe [^ ]* to highlight up to
the next space.

Use proxy from the internet? Port forward? Besides browsing I need the p2p. Any ideas how to solve this problem will be appreciated. There is nothing currently to do about this, the correct technical term for what 012 are doing is Deep Packet Inspection. They are probably using something like [1] to QOS p2p traffic. They are not blocking ports, they are reading the content of your traffic and analyzing it in real time, these packets that are labeled as low priority get Throttled. I'm also connected to 012 using HOT, for the last 3 months I'm experiencing an ever degrading performance of popular file sharing protocols such as ed2k and bit torrent. It get's to such ridicules rates as 3KB/s. I can verify this is an ISP issue, because : a. I've made an experiment with my fellow college where we started downloading the same popular file, each from his own home simultaneously. He is connected via Bezeq+ADSL and I'm through 012+HOT. My download rate was 6Kb/s (max) while his maintained an steady rate of 55Kb/s. We're both connected using a Linksys Router, and made proper checking before started the test: Ports have been forwarded and verified to be allow connect(), other network devices have been disconnected. No other downloads / uploads were active. b. I've talked to 2 other friends at work, who are also connected using 012 and are reporting to experience the exact same service disrupts as I am. c. Please read these forum posts, discussing this issue : - http://forum.bgu.co.il/index.php?showtopic=165231pid=1673953 - http://209.85.135.104/search?q=cache:UV5wN3Sg4rYJ:selectv.net/lofiversion/index.php/t37336.html+012+%D7%97%D7%95%D7%A1%D7%9E%D7%99%D7%9Dhl=enct=clnkcd=9client=firefox-a We've spoke to 012 representative, it's always the same automatic answer they have been instructed to provide: Problem with your computer, spyware, virus, wrong usage No point in arguing with the poor technical support guy because he a. Can't help you. B. Probably does not have the slightest clue about what you are talking about. This leads me to the conclusion that nothing can be done besides leaving the company that insists on hurting it's costumers and join Bezeq, who may or may not be the best ISP around but at least they aren't using technology to hide cowardly acts from their users. I for one have lost my faith in 012 completely, I will not let this slip and have already started the procedure of disconnecting from 012 ASAP. I will also make sure all my friends + parents + who ever I can advice on ISP choosing to reconsider their decision based on the above. Maxim. [1] http://www.cyberoam.com/contentfiltering.html p.s.

UML 2.0 Design tools on Linux
Hello List, I'm looking for UML design tool. The target language is mainly java. I need a tool with nice interface, I don't mind it having a bit steep learning curve but I do want a good tool that can enable smart usage. The requirements are : 1. Support class diagrams with interfaces, concrete classes and inheritance. 2. Support sequence diagram 3. Enable exporting to Image formats. PNG is fine. SVG is better. Optional requirements : 1. State diagram's are a big plus. 2. Activity diagram would be nice but I can go along without them 3. Use case diagrams are not required. This tool can be Free Software (I would prefer this), but a proprietary tool will do as well. It would also be nice if it acted as MDA (+ADM) code generator, but again this is not a must. Now I understand this is a hot topic, there is a plethora of tools out there [1], [2], [3] the real problem is selecting the right one. Can some one on this list recommended a tool he has personal experience with and found it to be worthwhile ? Thank you, Maxim. p.s. In case some body is interested, or does not know UML.

Thanks, Don't give up so fast. linux-ha has lots of bugs that's true, but they all have either a workaround or fixes in the development / stable src releases. First thing I suggest you do is build a RPM from the development branch. The latest release is here http://hg.linux-ha.org/dev/archive/ef1be5978d97.tar.bz2. You can the package by calling sudo ./ConfigureMe package. Note that you will need libnet [1].

I'm basically a PHP programmer, though in the past two years I've been doing more integration work and problem solving than any web development (being the only one except our sysadmin who is not afraid of shell scripts). Now, this merger gives me a unique opportunity - I've been in my current company for 6 years, so I'm due a lot of compensation should I quit (quitting after an acquisition is considered being laid off), meaning I can basically keep my standard of living for at least 6 months without actually working. I can use these 6 months to develop my skills in some other area of programming, and maybe even get some experience by participating in an open source project of some kind. What I'd like your advice on is - what directions are popular, have high demand, and can accommodate a programmer with lots of general experience, but not particular (other than the web)? Preferably ones that don't enslave people (no golden cages for the chance of becoming a millionaire).

It seems that there were not even one decent company in Israel that would fall under these conditions. This was ~2 years ago. So they turned to .Net. I don't mean to be all too rude but: What about starting your own company? You definitely have the necessary experience, skill, motivation and with proper guidance/managements you could fill in a blank that is clearly missing here in the local market. I could even suggest this organization would be a hybrid of Django (which is getting hotter by the minute!) and php ajax software house.

This is the behavior he is familiar with from nearly every enterprise FW device. Here, on Debian OTOH he's instructed to script in /etc/network/if-pre-up.d to have the system load iptables rule set on boot, reasonable except for the single issue of him required to also _remember_ to iptables-save those rules on each modification. I find this process error prone. The is not a single utility (AFAIK) in Debian repository to automate this process. I think that the optimal work method would be for the system to write iptables rules on shutdown and have them restored back next boot. I'm doing this in my firewall script by taking actions on start|stop. Thus, you know that all you need to do is run iptables -A INPUT... to have your firewall ticking.

I agree that, perhaps, a mid or low priority debconf option to change it to auto-save every change would be reasonable, as long as it is not a default. I don't think you will find a consensus on what the correct behavior should be. I, for one, see this as reasonable. Debian is a general purpose OS. It's impossible predict the actual usage and environment in which it will be used. Consider the following defaults: Squid defaults to a restrictive mode by default (no access) DHCPD will start automatically upon installation CUPS web access is restricted to localhost Exim is the default MTA DHCP client will not send the hostname While I find those annoying, I would not consider them bugs. Because they aren't. Those are limitations by design, some due to security considerations while other are purely because of popcon statistics. iptables on Debian OTOH is simply put Plain Broken. It is not usable for 99% of the use cases, which is why I think action should be taken. Perhaps a versioning framework should be developed and have iptables recommend iptables-persistent or something like that. I'm thinking about a script that can run either in sysv mode or in daemon mode that will monitor the active rule set and if needed create new revision of the rule file, save the current rules and generate md5 hash to verify everything is OK on next reboot.

Re: bidiv and the default $COLUMNS value

As suspected, I got an odd number: 99. Question: Where is this value defined ? I completely missed this question (which has nothing to do with bidiv). So here is a brief history of COLUMNS... COLUMNS is a variable set by your shell (zsh, bash, tcsh, or whatever you're using). The idea is that your shell knows what is the width of your terminal and passes this knowledge to the programs it runs; A few of the familiar Unix programs use this knowledge - for example ls by default shows the file listing in multile columns, up to the terminal's width. As you saw, bidiv also uses this variable. In the old days, terminals used to have fixed widths; If you had a vt100 terminal (TERM=vt100), then the width was always 80. If you had a ATT 5620 terminal, the width was 88, and so on, and the termcap or terminfo libraries was used to get this information based on the terminal name. However, when resisable windows appeared in Unix (on the aforementioned 5620, and in X-Windows), this fixed width was no longer enough, and the terminal's (or actually, terminal emulator window's) width could be changed at any moment. This is when three new facilities were added to Unix. First, a window width/hight setting was added to the tty (the tty is the Unix mechanism for a terminal emulator to connect to a process, usually a shell, running in it). See stty -a (and the TIOCSWINSZ ioctl). This was almost enough - your shell and the processes it runs can now figure out at any moment what's the window's current size. But should the shell (which needs to know the terminal's width, e.g., for command line editing) try this ioctl on every command? Instead of forcing it to check every time, a new signal was invented - SIGWINCH, window change. When the terminal emulator is resized, it sends its child process (namely, your shell) a SIGWINCH signal. The shell then uses the ioctl to get its current window size, and remembers it. The third mechanism is a shell variable, COLUMNS, which gets updated when the shell learns of a new window width. This feature is useful because ioctl's are nonstandard or complex and using variables is easier; it also allows the user to easily override the width; And it also works with pipes and redirections. Learning something new everyday. What is tput then? I know it speaks with the terminfo db and that it's a rather portable to method to encode color strings (try tput setaf 1; whoami; tput setaf 7). I assume this adds a fourth mechanisms? ncurses being 5th? [EMAIL PROTECTED]:~$ echo $COLUMNS 88 [EMAIL PROTECTED]:~$ tput cols 88 #resizing window...

Querying apt for package repository source ?
Hi, I'm preparing my laptop for egdy to feisty upgrade. My first step is identifying all packages installed on my system coming from not official Ubuntu repo. I've started by commenting out all of them from sources.list (have ~5 of those), following sudo aptitude update. This gave me all foreign packages under Obsolete and Locally Created Packages in aptitude interactive mode. Now I wish to continue by resuming the previously commented out repositories, and identifying each package from which repository it comes from. This will give me a perfect status on required steps to accomplish a successful upgrade and more importantly could suggest what software will break (because no feisty deb has been created for it yet). So, to make a long story short - How can I query apt-get/aptitude/apt-* for package from repository data ? Thanks guys. P.S, OT, btw, foo-msg and co. This whole thing it to get subversion v1.4, which for some reason (bad!) has does have rpm for RH4 but no .deb for Debian 3.1/Ubuntu 6.10. This in turn to enable me seeing meld diff of a checkouted source on the RH4 box (using svn1.4) from on a mapped via sshfs folder in my Ubuntu 6.10 laptop. Meld FYI can automagically detect that you are diffing from an svn directory and display you those diffs (local copy vs. HEAD revision). -- Cheers, Maxim Veksler Free as in Freedom - Do u GNU ? = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

wrong, there is not a inch of complaint in this reply it's that I'm
amazed that such a simple request can't be answered with apt-magic
repository php5-gd.
I do think it's an exotic request, and the reason is that it's not in
APT's responsibilities.
Apt should manage software installation and removal, which it does based
on your installed packages, and your *current* repositories. What you're
asking needs information also on *past* repositories.
Lets look at unstable, in which packages come and go relatively quick.
It mean, that if I don't update daily, I can find myself with installed
packages which currently doesn't exist in the repository. From where
should apt take the info about the source repository?
I think I was not clear enough on my question.
I don't ask apt to store history of download source of package, all
I'm asking is that with the current state, when all repositories are
configured in sources.list to get a reply from apt that if I ask for
package X he will wget it from http://heaven.org/angel.deb.
To follow your example for unstable: I don't care for updates. You
have your local copy(s) of Packages.gz please tell me what package you
choosed (after you ran you algorithms.cc) and from what repository
will you be fetching it, that's all I'm asking.
On a more technical side:
When you create a package, you do that regardless of any repository, so
there isn't any meta data about that. Before installation APT (and
aptitude) will resolve the package dependencies and download the .deb
files. From there, the installation is done with DPKG, which doesn't
know anything about repositories. Same as you would have done the
installation manually with DPKG.
I hope this answer is enough. Please let me know if you want more info.
Anyway, I've started looking at the issue. It seem that the real horse
behind apt is libapt (/usr/lib/libapt-pkg-libc6.3-6.so.3.11.0). I
can't seem to able to find any documentation for the API.
$ apt-cache show libapt-pkg-doc
[snip]
Description: Documentation for APT development
This package contains documentation for development of the APT
Debian package manipulation program and its libraries.
From a quick play with python-apt, it seems that apt will not report
this info to the upper layer. Pasting from apt source
apt-pkg/pkgrecords.h pkgRecords does not have such field:
class pkgRecords::Parser
{
protected:
virtual bool Jump(pkgCache::VerFileIterator const Ver) = 0;
public:
friend class pkgRecords;
// These refer to the archive file for the Version
virtual string FileName() {return string();};
virtual string MD5Hash() {return string();};
virtual string SHA1Hash() {return string();};
virtual string SourcePkg() {return string();};
// These are some general stats about the package
virtual string Maintainer() {return string();};
virtual string ShortDesc() {return string();};
virtual string LongDesc() {return string();};
virtual string Name() {return string();};
// The record in binary form
virtual void GetRec(const char *Start,const char *Stop) {Start =
Stop = 0;};
virtual ~Parser() {};
};
The Ubuntu upgrade is almost over here, I don't think I will be
pursuing this issue any further.
Thank you for the answers Lior.

You too, and keep up the great work.

Ubuntu sudo security (was : debian netinst q)
On 4/27/07, ronys [EMAIL PROTECTED] wrote: Hi, Regarding root, IIRC, 'sudo' is configured to allow the user to get root access, e.g., 'sudo bash' should give you a root shell. This is the approach taken by Ubuntu as well - root itself is disabled, all root work done via sudo. The idea behind this is better security. I'm not ocnvinced that this is the case, but that's the intent. Security? I think it's a combination of convenience for the user and a very weak form of obscurity. For the root user I would choose a better, longer, more random combination of characters then I would set for my own daily used account. The attacker would surly have easier time breaking into my account then the root account for several reasons: ssh noroot, password, automatic blocking of failed attempts and more. There are several situations where you might provide your password to a fellow friend, this does not mean you like to give him complete control over your box. For general system administration. You are playing with your environment, you might have some binary which you placed in ~/bin/ there is the a chance of you using sudo to by mistake running something from this bin path, take for example sudo mkdir newdir, mkdir is a bash wrapper script the checks if the dir exists and if it does it first rm it (a stupid script, but for the sake of example it will do) the only issue is your wrapper script has a bug causing it to rm /home or even better /. If you'd use su - such stuff would never happen. I can think of several more reasons where the normal user should not be granted by default root access, think of ssh private-key logins done from your laptop to your server machine done by a 3rd person. Generally speaking I think that this is a Ubuntu bug that is OK for the desktop version but should be avoid for anything else.

I am assuming every DGW is on a different pppX ? If so, you can simply use
ping -I iface (where iface is other IP of the interface or device name).
If not, and they all go through the same interface, I guess routing by

My question is am I doing something wrong or is this the way it's supposed to work or do I need to script the grepping of ifconfig by myself? In case anyone wonders, I'm attaching the config files I'm using to connect with pelephones' DATA POZ thingy on Ubuntu 6.10 (copy paste from dokuwiki format). Configuration files * cat /etc/wvdial.conf file [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 C1 D2 +FCLASS=0 Modem Type = USB Modem ISDN = 0 New PPPD = yes Phone = #777 Modem = /dev/ttyACM0 Username = [EMAIL PROTECTED] Password = pcl Baud = 460800 /file * cat /etc/ppp/peers/pelephone file # This optionfile was generated by pppconfig 2.3.11. # # hide-password noauth connect /usr/sbin/chat -v -f /etc/chatscripts/pelephone debug /dev/ttyACM0 115200 defaultroute noipdefault user [EMAIL PROTECTED] /file * cat /etc/chatscripts/pelephone file # This chatfile was generated by pppconfig 2.3.11. # Please do not delete any of the comments.

You can get a similar effect by using systemtap on a kprobes enabled kernel. It's actually much stronger than syscalltrack. Thanks for the tip. It's an interesting utility, but not suitable for production (IMHO). I need to monitor a very low and minor activity on a production server, doing a kernel level break point for traps just sounds bad. How do I check if my kernel was compiled with kprobes? Thank you.

Using the code of dead project - Political question
Hello List, A political question if I may. What to do if you wish to use the code of some GPL'ed project hosted on sf.net but the project is dead? Do you fork the project for your own code, or do you start maintaining two different projects? More specifically - I would like to use DAXFi which has been dead for 5 years now. It looks good and it will pretty much fit the bill (if it works). Now, if I decide to use it I will probably custom fit it for own purposes, leaving only the XML core logic. How should I approach this? Should I contact the developer and ask his permission to do so? Should I simply inform him that I will be forking his code? What have you done in a similar occasions? Thanks, and good week to all.

I would like to comment that I had no idea source (.) actually runs
the file it's sourcing. I was sure it's just a quick short cut to
typing each command at the terminal.
Because I've used it for something that is cool (IMHO) I would like to
share with the list.
I'm patching our dev's environment and was looking for a way to
automate the PATH setup for them (taking into account that not all the
devs are unix gurus).
We are using subversion as the scm and scons as the builder. Note that
the scons version is local, that is you get it with the source once
you checkout, no install is needed (besides python, obviously).
With the help you Meir and Peter I now have a setup the allows me to
dynamically set the PATH variable once a developer cd's into the root
of his checked-out working copy.
The OS is RH 4 WS, the shell is bash.
It's set up is the following way:
$ cat /etc/profile.d/hooks.sh
# Add custom hooks to user-activity in the shell
export PROMPT_COMMAND='[[ -x Utils/bin/local_setup_bashenv.sh ]]
source Utils/bin/local_setup_bashenv.sh'
$ pwd
/home/hq4ever/development/builder
$ cat Utils/bin/local_setup_bashenv.sh
#!/bin/bash
for export_val in $(python Utils/bin/local_setup_environment.py); do
export $export_val; done
$ cat Utils/bin/ml_setup_environment.py
#!/bin/python
import os
def find_svn_wcroot():
homedir_len=len(os.getenv('HOME').split('/'))
cwddir_len=len(os.getcwd().split('/'))
cwddir_text=os.getcwd()
for i in range(cwddir_len, homedir_len, -1):
if not os.path.exists('/'.join(cwddir_text.split('/')[:i]) + '/.svn'):
return '/'.join(cwddir_text.split('/')[:i+1])
#else:
#print 'Still ok: ' + '/'.join(cwddir_text.split('/')[:i])
+ '/.svn'
def setPATH(export_environment):
try:
os.getenv('PATH').split(':').index(find_svn_wcroot()+'/Utils/bin')
except ValueError:
export_environment['PATH']=[find_svn_wcroot()+'/Utils/bin'] +
os.getenv('PATH').split(':')
export_env = {}
setPATH(export_env)
#export_env['SOMEVAL']=['maxim']
for (k, v) in export_env.items():
print k + '=' + ':'.join(v)
Note that I've only written it today and haven't actually tried to
work with it, so bugs are real.
