Server :: Writing Debian Init Script For Process That Has No Syslog Integration?
May 18, 2011I have inherited ownership of a Debian server process that logs its error message to stdout/stderr. Currently its initscript has lines like:
start-stop-daemon [options] --exec $DAEMON -- $DAEMON_ARGS < /dev/null 2>&1 | logger $LOG_OPTIONS 2> /dev/null &
I have tried to abstract as much of that away as possible. The options specify a pid file, to make a pid file. A subsequent line tries to establish whether the process is up, though I think several conditions are not checked for. This script seems pretty ropey to me. I am trying to start again with the lsb-base one in /etc/init.d/skeleton though that is going to require a lot of modification. get the code change to use the syslog API however that is out of the question at least for now.
1.) Create a named pipe
2.) Start up a logger daemon that reads from the named pipe
3.) start up the server process that writes to the named pipe
It would be ideal for this if start-stop-daemon offered options to specify where the IO of the daemon process should be redirected to. However I am not about to offer to adopt that package (with ~400 bugs) so I doubt that will happen. Trying to specify the redirection on the command line does not work. In the case of the logger daemon start-stop-daemon seems to hang on the system call. In the case of the server process the pipe gets closed when start-stop-daemon exits, so the logger daemon exits. None of that seems surprising.So what I am doing now is to write simple wrapper scripts for the server and logger processes. Both wrapper scripts have this structure:
1.) sanity check the arguments
2.) exec program [suitable redirection of IO]
Then the start-stop-daemon can call the wrapper scripts as daemons. From my experiments so far this seems to work. However I feel a bit uncomfortable with this. It introduces several new wrapper scripts.I cannot think of any obvious security holes but I suppose race conditions are inevitable.

Fedora Servers :: Samba Messages In Syslog - Allow Logging To The Standard Samba Logfiles
Mar 18, 2010I wish to prevent the samba messages (mainly nmbd and winbindd) from appearing in the system log (/var/log/messages). I want to allow samba logging to the standard samba logfiles, but prevent the syslog getting clogged up by samba. I added syslog = 0 to smb.conf and reloaded the config but the messages were still appearing. I also tried the following (and restarted the syslog via /sbin/service syslog restart) # Suppress messages from samba.
nmbd.* /dev/null
smbd.* /dev/null
winbindd.* /dev/null
For interests sake the messages I'm getting are below (I'm not concerned about the messages themselves, I can chase them up at my leisure via the samba logs) Mar 18 09:58:29 SERVER nmbd[3808]: query_name_response: Multiple (2) responses received for a query on subnet xx.yy.z.zz for name DOMAIN<1d>.

Server :: DHCP: Logging Host Names In Log File?
Jul 7, 2009What I am trying to do is log IP Address, MAC Address and the host name for records. So I can have a record of what PC got which IP address and when they got it. So far my search has yielded no results. It would not be that big of a deal as I could always look at the dhcp file, but it is generated dynamically (3rd party application using RADIUS and each user gets a host).
subnet 208.x.x.0 netmask 255.255.255.0 {
option routers 208.x.x.1;
option subnet-mask 255.255.255.0;

Ubuntu Servers :: DHCP Server And DHCP Client Simultaneously?
Aug 4, 2010I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.
View 4 Replies View RelatedUbuntu :: How To Stop Logging Cron To Syslog
Mar 2, 2011There was an useful discussion on "how to stop logging cron to syslog". The useful answer is to update the line targeting syslog in /etc/syslog.conf to say something like:
Code:
*.*;auth,authpriv.none,mail.none,cron.none -/var/log/syslog
the significant part being that cron.none means that cron will not log to syslog.
There was discussion about whether this was a good thing to do, but omitted to suggest that adding/ uncommenting the following line would mean that no information would be lost but that syslog would be less cluttered as a source of monitoring info:
Code:
cron.* -/var/log/cron.log
You've still got all your cron-related log items available in cron.log if and when you need them. To make the new /etc/syslog.conf lines effective you should also, with root privileges:
Code:
touch /var/log/cron.log
chown syslog:adm /var/log/cron.log
and restart syslog. In my case:
Code:
/etc/init.d/sysklogd restart

View 2 Replies View RelatedUbuntu Servers :: Windows DHCP Server - Multiple Boot Servers ?
Apr 1, 2011I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
From: [url]
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
General :: Prevent The Logging Of Commands Run Into Syslog As Post-shell Expansion?

Networking :: Slightly Higher Level Traffic Logging
Mar 19, 2011Summary: Several school networks in need of a fairly low-level way to log network use, especially Internet. Raw packet captures are too low (and big). Turnkey solutions we've looked at (Untangle) aren't really a good fit. This seems like a common issue. Detail: For legal reasons, we have to be able to roll back time every so often (ie. when death-threats are made on some web-forum). Currently, our traffic logs on Internet traffic are pretty high-level and aren't really useful to point a finger at the guilty or away from the innocent. We also like to keep our users honest by providing them with data about their own computer use (ie. what are the top 10 websites they hit).
I've been building up rules with iptables and ulogd to log the creation of new connections and save it to a PCAP formatted file for consumption by some very simple analysis scripts, or examination with Wireshark if required. Just logging new connections prevents the logging data from getting large in a hurry, but also doesn't give us a lot of information we would like (ie. the amount of data transferred). We've been examining products that offer fairly full-featured analysis, notably Untangle, but we do a lot of weird stuff (VOIP, VC, VPNs) with traffic flowing through very minimal hardware (PC Engines) running Linux. This is very inexpensive and very flexible, and we like it that way.

Ubuntu Servers :: Server For Internet Logging And Filtering
Jun 16, 2010I'm in charge of a church computer lab which is open to children ages 6 to 16 for about 3 hours a week. We try to have adult supervision but don't have 100% coverage.
The lab has a maximum of 8 computers, a mixture of MACs, Windows XP, and Linux machines, depending on their state of repair.
The church's current internet connection is Verizon residential speed DSL to a 4 port wired plus wireless router in a locked office which also houses our Windows XP office computer and is adjacent to our locked pastor's office.
Internet access for the lab is by a single CAT5 cable passing through a small hole in a wall to a network switch on the other side. All of the lab computers are connected to the switch by CAT5 cable.
I would like to add a server in the locked office to log internet usage and block access to certain websites as needed. I think logging internet activity will be a good antidote in case one of the older ones wants to try to get sneaky and cover their tracks.
I envision building a computer from donated parts, including 2 NICs.
I have never done things from the server end, but think the server edition of Ubuntu would be a good starting point.
My goal is to be able to manage internet access with an easy to use GUI system so I could teach the basics to a couple of youth leaders to use it when I'm not there.
Ubuntu :: Turn Off Logging By Desktop Couch?
Jun 23, 2010Desktop couchdb builds up a pair of log files in:~/.cache/desktop-couchdb.log.1~/.cache/desktop-couchdb.stdout.1It appears they then get rotated to *.2 and *.3 before disappearing.In my case, having uninstalled Ubuntu One, I think the desktop couch DB is only there supporting Gwibber. Both log files seem to be HTTP access logs - referring to HEAD and GET - not much value really.If the machine is up for several days, these logs get quite large. I think they were up to a combined 700MB after 12 days uptime before I rebooted today.There's a settings file /etc/couchdb/local.ini but the log level therein only seems to affect the log under /var/log/couchdb.Anyone know how to stop this logging under ~/.cache?
