Errors Compiling 1.5.19 with TCP_WRAPPERS

syslog-ng 1.4.7 crashing randomly
by Adam Steffes 21 Aug '02

21 Aug '02

I'm running syslog-ng 1.4.7 on a Solaris 7 machine which acts as a middleman for my production servers and main log repository server. It crashes without warning, without logging any problems beforehand, and often requires several attempts at restarts before staying up. Time between crashes seems random; it will go for a few days, die, require ten restarts in five minutes to keep it up, then run for another week before having any problems. 'gdb' says it's dying from a SIGKILL but I don't have anything running on the machine that would send it any such flags. Any ideas what is going on here? I found two messages in the archives from Oct. 2001 asking similar questions, but no resolutions: Nicholas Berry nberry(a)ragingwire.com Wed, 10 Oct 2001 09:10:13 -0700 a.. I too am having the same issue with crashing under Solaris 8 with syslog-ng 1.5.10, but my crashes happen several hours between each other. _________________________________________________________________ Nicholas Berry RagingWire Telecommunications, Inc.

Ok, that's strange... apparently the patch didn't apply correctly (according to the output of that tail command), even though the output from patch appeared that it did; It still had the old code in sources.c. I re-applied the patch, verified that the source was indeed patched this time, and recompiled. After a bit of testing, I don't seem to be getting the truncated entries any more, so I'm guessing it was just an error on my part during the patching and re-compiling process. Thanks for your help in debugging (: I hadn't even thought to actually look at the source for the original problem since it had appeared that the patch applied correctly. --- Dustin D.

Balazs and everyone, The first fix which was posted to the list changing the if to be: if (!eol && closure->pos == closure->max_log_line) appeared to work correctly for me. The second fix posted which changed the if to be: if (!eol && (start_pos == 0 || closure->pos == closure->max_log_line)) had the same (broken) behaviour as the unmodified if. This leads me to conclude that 'closure->pos == closure->max_log_line' is false, '!eol' is true and 'start_pos == 0' is true. log_msg_size() does not appear to have any effect. I have increased it to be 2048 and still my logs are split amoung lines. Message length doesn't appear to matter either as messages which are longer can end up being intact while shorter messages are split. The one common factor is that all of the messages being split are coming from /proc/kmsg. Since there was some concern about UDP messages being broken by this my first thought is to change the if to be: if (!eol && (closure->dgram || closure->pos == closure->max_log_line)) This makes the assumption that messages coming from streams such as a TCP connection or /dev/log or a file/pipe will eventually have a terminating newline or \0. Of course, it keeps the sanity check to not create messages over max_log_line. I have this working on my setup now but I don't swear that it's perfect, I'd love to hear feedback on it, esp. from Balazs. These messages being split causes me a real problem on my firewall.

Cisco PIX TCP syslog stream format - and UDP truncation.
by Ted_Rule＠flextech.co.uk 21 Aug '02

21 Aug '02

I have a little problem with a PIX using UDP syslog to an old syslogd server, which I'm hoping members of the list may be able to assist me with. Some time ago, I noticed that some of the bigger messages were being truncated. Further investigation suggested that Cisco were imposing a 256 character limit on messages sent via syslog. The problem is rarely seen - mostly it shows up with IPSEC key renewal messages which happen to be very long. After several "oh yes it does, oh no it doesn't" rounds of trying to convince our suppliers, and in turn Cisco - who initially swore blind they couldn't reproduce the fault - Cisco finally admitted that they do indeed impose a 256 limit on UDP syslog messages. The PIX is perfectly capable of handling bigger UDP messages than that - it has to do in order just to process DNS messages - so the problem only affects the PIX UDP syslog stream. Cisco also recommend , of course, using TCP instead, which they haven't apparently imposed such a restriction on; TCP usage would also help to improve the general security of the logging process, which would also be a good thing anyway. Cisco don't appear to be very interested in my request to patch the UDP message buffer size; I think it would be nothing more than a single line code change to raise the buffer size to 512 which should easily cover any IPSEC syslog messages I can see being truncated. I'm strongly considering migrating the syslog server to syslog-ng so that I could support TCP syslog streams anyway, but in order to defend against any migration problems I wanted a backup plan for PIX TCP stream support. My current plan is some form of very temporary perl daemon listening on TCP redirecting to the Unix Domain syslog socket. So. Does anyone on the list have experience of Cisco PIX TCP Syslog stream talking to syslog-ng? Does anyone on the list have a good idea of the internal layout of the PIX TCP syslog stream - in particular how is the end of message encoded? ( Under UDP of course , EOM is implied by end of packet, but under TCP some explicit EOM marker would have(?) to be added to the stream. ) Would anyone be able to send me some tcpdumps or similar for me to decode the format so that I could generate some test data to fire at the listener?

logging pauses and log entry truncation
by Dustin Trammell 21 Aug '02

21 Aug '02

Has anyone else experienced syslog-ng occasionally pausing for a few minutes, immediately after logging one or more truncated entries? It usually pauses for anywhere from 1-10 minutes or so, and the process seems to be fine during this time (still bound to the port, doesn't appear to be zombied or using up all the CPU or memory, etc), then it continues after the pause as if nothing happened. The entry immediately after the pause is sometimes truncated also. The lines that are getting truncated appear to always be kernel log entries, more specifically from iptables, so I tried both using klogd as well as a file() source using /proc/kmsg, both with the same results. I saw a thread a few days ago about garbled/truncated entries, and what I got from that thread was to set the log_msg_size() option to something larger than the largest line your expecting. I set mine to 2048, and that still has not solved the problem, so I'm not sure if it's the same issue that has been discussed in the previous thread or something different. Below I've listed a few log entries (gathered from tail -f logfile), and my syslog-ng.conf file is appended below my sig. ---8<-----(snip)-----8<--- Aug 12 08:10:01 172.30.10.3 arpwatch: eth7 bogon 192.168.168.14 0:4:c0:3:a8:0 Aug 12 08:10:01 172.30.10.60 traqer: doing 10 minute stuff Aug 12 08:10:01 172.30.10.60 kernel: fwlog output accept db IN= OUT=ipsec0 SRC=172.30.10.60 DST=172.30.10.61 LEN=60 TOS=0x00 PREC=0x00 TTL=232 ID=1196 PROTO=TCP SPT=51118 DPT=5432 WINDOW=32440 RES=0x00 CWR ECE SYN URGP=0 Aug 12 08:10:01 loghost01 fwlog input drop cleanup IN=ipsec0 OUT= MAC=00:06:5b:84:60:7e:00:08:02:10: (pause) Aug 12 08:20:01 loghost01 fwlog input drop cleanup IN=ipsec0 OUT= MAC=00:06: Aug 12 08:11:05 loghost01 stunnel[23914]: httpd connected from 172.30.8.40:47705 Aug 12 08:11:05 loghost01 stunnel[23914]: SSL_accept: Peer suddenly disconnected ---8<-----(snip)-----8<--- Aug 12 11:01:29 172.30.10.60 pluto[3590]: "itdb" #814: ignoring Delete SA payload Aug 12 11:01:29 172.30.10.60 pluto[3590]: "itdb" #814: received and ignored informational message Aug 12 11:01:29 loghost01 fwlog input drop cleanup IN=ipsec0 OUT= MAC=00:06:5b:84:60:7e:00:08: Aug 12 11:01:29 loghost01 fwlog input drop cleanup IN=ipsec0 OUT= MAC= Aug 12 11:01:29 loghost01 fwlog input drop cleanup IN=ipsec0 OUT= MAC= (pause) Aug 12 11:06:49 loghost01 fwlog input drop cleanup IN=ipsec0 OUT= MAC=00:06: Aug 12 11:02:07 loghost01 snmptrapd[31633]: 209.48.214.5: Enterprise Specific Trap (500) Uptime: 6 days, 16:43:47.00, SNMPv2-SMI::enterprises.3224.2.1 = 40, SNMPv2-SMI::enterprises.3224.2.3 = "ALARM: vpn \"LC*Lon-VPN\" is up.

PID of programs
by harald schmidt 20 Aug '02

20 Aug '02

hello, I'm using syslog-ng to let my loghosts log to MySQL-databases as described under www.vermeer.org/syslog. Is it possible to filter the PID of a program to write it to an extra column of the MySQL table? This would be very useful to filter for example the sendmail-process of one mail. There are ~7 entries from sendmail for one mail, because of the virus scanner. Would it furthermore be possible to disperse the message in "to=.." and "from=.." to let that fields go to extra columns, too. thanks Harald -- Neu: Fakten testen jetzt noch günstiger 35% billiger + ein Geschenk Ihrer Wahl!! http://bonus.gmx.net/?gid=46842444&prid=687

output format to remote syslog duplicates info
by Clemson, Chris 20 Aug '02

20 Aug '02

Hello! I've been playing with syslog-ng, which is great, but I have a question. I am logging locally, and forwarding on entries to a remote syslogd (SL4NT). both work fine, and the entries in the /var/log/ syslog files are fine. However, on the SL4NT machine, the message entries include the date and machine name in the message log, even though it is included as fields in SL4NT. This behaviour doesn't happen when normal syslogds forward to my SL4NT server. Is there a way of turning this off by default? I'd prefer not to have to write templates for each rule I want sending to a remote syslogd. does anyone know if there is an option to turn this off? thanks! chris -- The content of this e-mail is confidential, may contain privileged material and is intended solely for the recipient(s) named above.

[bug] Output templates.
by Sergey Y. Afonin 19 Aug '02

19 Aug '02

Hello. I think what I find one small bug in templates. The messages in log file have "\" before some symbols (",' etc). For example, log file definition: destination d_lan_by_host { file("/var/log/lan/$HOST.log" template("$DATE $MESSAGE\n")); }; The log file line is: Aug 18 12:28:53 At 07:28:50, Facility \"Auth Facility\", Level \"VERBOSE\":: A call, call id = 34996311, has arrived on interface slot:3/mod:23 The normal line is: Aug 18 12:28:53 At 07:28:50, Facility "Auth Facility", Level "VERBOSE":: A call, call id = 34996311, has arrived on interface slot:3/mod:23 Is it for normal file name generation, isn't it ? But it's not very suitable for log file... The version: 1.5.19 -- Regards, Sergey Afonin asy(a)kraft-s.ru

Hi, 2 changes on the sample config file for syslog-ng, I would prefer: * set the fileoptions (owner(), group(), perm()) in the global section * the file for logs of the facility user should have permission 644, that users can see, what they have done. Joerg.

RE: [syslog-ng] logging pauses and log entry truncation
by Dustin Trammell 14 Aug '02

14 Aug '02

I can't comment on the /var/log/kern or /var/log/bootup stuff, as I simply have ALL logs go to a single file and do post-processing on it nightly which filters, splits, etc., and so far I have not had any problems with it failing to log to the logfile at any point. Because I'm sending all logs to a single destination (actually multiple destinations, but the point here is that ALL logs go to them), I don't set the log-level in my iptables statements, but I do set the log prefix: iptables -A INPUT -j LOG --log-prefix "$pkey input drop cleanup " iptables -A INPUT -j DROP So perhaps the log-prefix option could be the cause of the problem since we're both using them. If I get some time this afternoon I'll remove those from a test firewall and see if it continues to mangle/truncate the iptables log entries. --- Dustin D.

Could this possibly be the problem? If iptables is adding these prefixes to late? I dont know :P Thanks, Caylan

RE: [syslog-ng]Problems compiling libol / syslog-ng

Check the time on your system, it's probably wrong. Usually configure won't continue if it finds files that are newer than current date/time, or it creates a file that is older than current date/time. --- Dustin D.
