[Leaf-user] Daemontools package backup
i am using J.Nilo's package with LRP 2.9.8. everything works great, i can add a new service to be monitored by simply adding a symbol link in /service to the directory where my ./run file is included... however i cannot backup any new symbolic links that i create to run the services. a look at the daemontl.list shows: [snip] usr/bin/tai64nlocal service ^^^ etc/init.d/svscan var/lib/lrpkg/daemontl.* [snip] and at the daemontl.exclude.list: service/* does this mean that the links in service are not backed up with this package? if yes, then how can i backup any new links? thanks in advance kiril ___ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
[Leaf-user] Init CPU usage
hello list i am using lrp 2.9.8 as a base for a thin server. following peculiarity attracted my attention: the init process is very active (ps aux shows about 15 times the cpu usage of an idling ftp server) for about 10 minutes after boot up. after that, init uses virtually no cpu (as one would expect). could this be a hint of some misconfiguration somewhere? i use proftpd, thttpd, qmail, vpopmail, procmail, sshd, most supervised by daemontools. everything works perfectly, except that it makes no sense to me why init is so active so long after boot up. any hints will be appreciated :-) kiril btw, if someone needs vpopmail or procmail compiled for lrp - i should be able to make .lrp out of the binaries. ___ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
Re: [Leaf-user] How not to log a deny'ed packet/ip address
hello lynn it is the option -l which is responsible for the logging. you can redefine a rule like this: ipchains -R input 7 -s 10.0.0.0/8 -j DENY this replaces rule nr. 7 on the input chain. (rule nr. 7 was _my_ rule to deny traffic from 10.0.0.0/8 and log it, i used the above command to replace it.) you can of course decide to be more concious then me and log everything else but your rogue server. in this case you would have to insert a more specific rule ipchains -I input 6 -s 10.1.1.2/32 -j DENY which will silently deny the traffic from that specific server before the more general rule denies it and loggs it. it is impossible to determine the exact commands you would have to issue on your system (i do not use dachstein, so rules 10, 12 and 41 mean nothing to me). generally you should be able to use the same syntax that generated your rules in the first place, just avoiding -l. it is the IPCHAINS-HOWTO (http://www.linuxdoc.org/HOWTO/IPCHAINS-HOWTO-4.html) where more information can be found. there is also a great quick reference: http://users.owt.com/msensney/lrp/ipchains-quickref.pdf >I've got a rogue 10.x.x.x/32 server polling my Dachstein firewall >twice every 16 seconds for a dhcp server and a port 80 scan every >2 minutes.

[Leaf-user] established connections after client has disconnected
hello list i run an old version from charles steinkuehler (thank you, charles) on my gateway/firewall - works perfectly. there are a couple of servers masqueraded behind it to which specific ports are forwarded to. following problem occurs: host A from the outside connects to a service on the masqueraded server; host A disconnects (power off, programm shutdown, network failure) ; the masqueraded server keeps the connection - netstat says the connection is ESTABLISHED (as opposed to being FIN_WAIT2). is it possible that the firewall is blocking some sort of tcp or icmp communication that prevents such connections from being quickly identified as "not functional"? eventually these connections do get closed, but this takes time. are there some parameters to tune? i do not know the internals of the tcp/ip protocol well enough... maybe it is something really simple. hints are greatly appreciated. ___ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
Re: [Leaf-user] FTP Server - Change default ports
running a server behind a firewall on a different port requires a setup on the ftp server: following settings (for proftpd) are relevant: Port21 - change this to reflect your preferences MasqueradeAddress your firewall's ip address or domain name PassivePortsfromport toport the last two are needed to make passive mode work (people with firewalls will like you for doing this). check if your version supports these directives. you will have to port-forward your port of choice for the ftp server and the range of passive ports as well as the ftp-data port (20) to the masqueraded host. you will have to make sure your firewall accepts connections on these ports. how to do this is specific to your distribution / firewall. since i do not restart often, i just use a little script that does the port forwarding and have actually forgotten how to configure my router. ip_masq_ftp is not relevant to the question of running a masqueraded ftp-server. i am not sure however what to do with the ftp-data port if 2 or more ftp servers run on different ports. i did consult ftp.echogent.com/docs/FTP_and_Firewalls.pdf (very good reading, btw.) -Ursprüngliche Nachricht- Von: Simon Bolduc <[EMAIL PROTECTED]> An: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Datum: Mittwoch, 12.

Re: [Leaf-user] Re: hn.org and domain names
if you want to map ronin-tech.com to your machine with hn.org you need to do two things: 1) create a vanity account (hard nowadays, because hn is at the limit of its resources, but not impossible) - lets call it rt-vanity. once you have updated your ip with hn.org (there is a web page for this, a protocol description and iz-ipupdate.lrp package), rt-vanity.hn.org will map to your machine - you can test at this point. if 24.*.*.* is your ip address, than this part is working. 2) create a virtual domain account with hn.org and enter your ronin-tech.com domain. after you have updated your nameservers (this step you have done apparently), you must have your domain verified. only after your domain is verified (there were some problems with verification) can you insert ns-records to manage your domain. since you are doing a dynamic address mapping then you must add them according to the following schema: Example to map www.ronin-tech.com to a dynamic ip 24.*.*.*: Assuming rt-vanity.hn.org is a vanity account that maps to 24.*.*.* and gets updated regularly to reflect ip address changes: Rec FQDN - www.ronin-tech.com Rec Type - A Rec Value - rt-vanity.hn.org DynDNS - 1 The one you enter here causes the record value to be the numerical ip address of the rt-vanity.hn.org (which is what your machine listens at). once you have one of these, you can always add CNAME records pointing to the ronin-tech.com record - this is what i do. you probably can also add more A records with DynDNS value 1. i have no idea what hn would prefer performancewise. after you are done, you can see if www.ronin-tech.com resolves to your machine. it takes a couple of minutes, then you can ping www.ronin-tech.com (on a winntserver it takes much longer than i am willing to wait so i usually reboot the machine) and see how it resolves. depending on your firewall configuration you may or may not be able to see your site in your browser. test from outside. the documentation on hn.org is somewhat cryptic, but it is there. hope this helps, kiril -Ursprüngliche Nachricht- Von: Erich Titl <[EMAIL PROTECTED]> An: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Datum: Mittwoch, 30.

Is there a simple and reliable way to test the status of a connection? a script that can runs constantly, supervised by daemontools, and restarts networking after some waiting period is what i am looking for. ping somehow does not work best. the host that i am trying to ping could go offline, dns could fail and constantly pinging some other host seems not particularly friendly to me. i tried also ip addr show | grep eth0 | grep inet, but this also did not really work out, because routing could fail. one could always test all conditions, but before i do this, i would like to ask the list if there is a more elegant way. regards, kiril ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm leaf-user mailing list: [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user SR FAQ: http://leaf-project.org/pub/doc/docmanager/docid_1891.html
Re: [leaf-user] Detecting Disconnected Network
... and now also to the list (forgetting to hit reply to all is frustrating...) hello ray! your assumptions were correct, here are the details: a cable modem on eth0; my provider gives out a dynamic ip address (which rarely changes); dhcp is handled by pump; lease is renewed once per hour; if i get a new address, a short script updates dns; problems are actually really rare (or rather those problems that do not resolve on their own): pump died once (after about 60 days uptime) - but there is not much to be done here, apart from restarting; two times service was interupted at about 4:00 am; in such a case the host ends up with a eth0 up, but without an ip address for eth0. default route is also not available. restarting the network solves connectivity issues; very, very rarely i have to reset the modem itself (maybe less then 1 time within last year) to get back online. i have no clue as to why this might happen. a search on the internet gave me this hint: if a dhcp server goes down, pump will bring the interface down even if the router works - maybe my isp is doing some maintenance on his dhcp server; maybe my cable modem gets reset due to some kind of maintenance; maybe sometimes the network just needs to go down, just to make sure there is still someone to bring it up... ... really, no idea... my last version of the script for pinging hosts follows. if there is a more elegant and reliable way to react in such rare situations, i will be glad to hear it. regards, kiril #!bin/bash PING_REMOTE_HOSTS="host1.com host2.com host3.com" for HOST in $PING_REMOTE_HOSTS do UP=0 while [ $UP -eq 0 ] do sleep 120 ping $HOST -qc 1 >/dev/null 2>&1 UP=$? done echo "$HOST is down, trying next host..." done echo "network is down. restarting..." /etc/init.d/network reload sleep 60 -Ursprüngliche Nachricht- Von: Ray Olszewski <[EMAIL PROTECTED]> An: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Datum: Montag, 27.

Re: [leaf-user] Detecting Disconnected Network
hi erich your version has the advantage that the hosts are rotated, so i can poll much faster. initially i just wanted to ping one host and keep the others as a reserve in case the first went offline. however this delays recovery, as the following log shows: 8 minutes before network was up again. so this brings up the next question, which is how to find reasonable delays before restarting the network and waiting for the network to go up before restarting it again. thanks to all, kiril [root@bay network]# cat current | tai64nlocal 2002-05-28 18:59:03.520783500 starting connection monitor... 2002-05-30 15:15:34.888502500 www.bol.de is down, trying next host... 2002-05-30 15:17:34.918443500 www.db24.de is down, trying next host... 2002-05-30 15:19:34.948508500 www.redhat.com is down, trying next host... 2002-05-30 15:21:34.978430500 www.linux.org is down, trying next host... 2002-05-30 15:23:35.008522500 www.ibiblio.org is down, trying next host... 2002-05-30 15:23:35.029444500 network is down. restarting... 2002-05-30 15:23:36.652992500 Setting network parameters: [ OK ] 2002-05-30 15:23:36.851080500 Bringing up interface lo: [ OK ] 2002-05-30 15:23:37.756420500 Bringing up interface eth0: [ OK ] 2002-05-30 15:24:43.112993500 starting connection monitor... -Ursprüngliche Nachricht- Von: Erich Titl <[EMAIL PROTECTED]> An: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Datum: Mittwoch, 29.

Re: [leaf-user] ftp forwarding problems...
assuming it is proftpd you are using behind your firewall, you will have to include following two lines in your proftpd.conf MasqueradeAddress yourhost.com PassivePorts 4 49000 and set up a port-forwarding for all passive ports to the internal server. you will probably not need 9000 ports though. without these two lines your server informs clients that its ip address is something like 192.168.1.45 (its masqueraded address) so the ftp client tries to connect to a server at 192.168.1.45 on an arbitrary port. this fails of course and you get a timeout. reading the manual is always a good idea to get a more thorough understanding of what is going on. regards, kiril -Ursprüngliche Nachricht- Von: Jeff Newmiller <[EMAIL PROTECTED]> An: Jeff <[EMAIL PROTECTED]> Cc: leaf-user <[EMAIL PROTECTED]> Datum: Sonntag, 2.

Re: [leaf-user] Detecting Disconnected Network
as you correctly suggest, i don't really need a waiting interval. what i really need is to ping a list of hosts every minute or so (the polling interval). if ping returns an error, then i have to check if other hosts are unreachable. i don't have to wait to do this check though. if i cannot reach those hosts, i can safely assume that i am offline and need to restart my network. if of course google, redhat and ibiblio are down at the same time, i can still be online, but this possibility is slight. maybe my modem requires some "rest period" and locks up if network is restartet too often. but then maybe not. some testing is required and in the worst case i will be wiring relays to the serial port :-) so i will rewrite my script to do the above mentioned. in case someone is interested, i can publish the result to the list. regards, kiril -Ursprüngliche Nachricht- Von: Erich Titl <[EMAIL PROTECTED]> An: Kiril <[EMAIL PROTECTED]> Datum: Freitag, 31.

In your version you jump from one host to the other as soon as one host is offline. This does not mean that _YOU_ are offline, it only means that you cannot ping that particular host.
