Jean-christophe Manciot modified a comment on ticket #67
@DiagonalArg Are you aware that each bashdb version/tag matches a bash version? The first post of this thread was written more than 1 year ago for Ubuntu focal when there was a bashdb tag matching a relevant bash version. Since then, Ubuntu has moved on to impish and so has my PPA which targets only the latest Ubuntu distribution. For the latter, bash version is 5.1.3 and bashdb is not compatible with that release. That's the reasons why you couldn't find any bashdb package on https://git.sdxlive.com/PPA/tree/Ubuntu/pool/stable/b....
-
@DiagonalArg Regarding your remark about the postinst, it is a leftover from older bashdb versions and it should have been removed. You're right, It prevents a correct installation of bashdb on bullseye. A new release has been posted without the postinst to allow a correct installation. You need to install a compatible bash version first with: # wget https://git.sdxlive.com/DR/plain/Debian/pool/stable/b/bash/bash_5.0-4+11.0_amd64.deb # dpkg -i bash_5.0-4+11.0_amd64.deb # apt-mark hold bash You can...

Cannot debug scripts called without their full path despite being in the PATH
-
I don't experience the issue you're refering to (4 years old) anymore. My question is even simpler: when I step on a script call from within a script, the second script is executed (correctly). But how can I step into the second script script_b.sh $parameter, meaning how can I get to the first executable line of that second script and execute step by step all instructions inside that second script?
-
It is very simple: how to step into a script called from with a script? script_a.sh: 1 2#!/bin/bash script_b.sh $parameter
-
My bad: the iptables rules for port 161 was open for TCP instead of UDP. Everything is fine now.
-
I have just found a walkaround: if I comment out all uncommented lines beginning with def of /etc/snmp/snmp.conf (default values) and restart snmpd, snmpwalk does work. The trace with -Dsnmp does not show the 4 lines containing default as shown in a previous post. That is very strange. Bottom line: the default values prevent snmpwalk from functioning correctly on one platform, and are not a hindrance on another one..
-
On both platforms, I got 5.8-685-gc71b9eb26.

On another platform with the same setup and a successul walk: snmpwalk -Dsnmp -v 3 -u OpenNMS -l authPriv -a SHA -x AES -A "authpassphrase" -X "privpassphrase" 127.0.0.1 .1 registered debug token snmp, 1 snmp_parse_args: handling (#4): v (optarg 3) (sp 0) snmp_parse_args: handling (#6): u (optarg OpenNMS) (sp 0) snmp_parse_args: handling (#8): l (optarg authPriv) (sp 0) snmp_parse_args: handling (#10): a (optarg SHA) (sp 0) snmp_parse_args: handling (#12): x (optarg AES) (sp 0) snmp_parse_args: handling...

Same issue: # libtool --mode=execute gdb snmpwalk GNU gdb (Ubuntu 8.3-0ubuntu1) 8.3 ... Reading symbols from snmpwalk... (No debugging symbols found in snmpwalk)
-
Also, I tried to build snmp with export CFLAGS='-g' to add debugging symbols, but I get: # gdb snmpwalk GNU gdb (Ubuntu 8.3-0ubuntu1) 8.3 ... Reading symbols from snmpwalk... (No debugging symbols found in snmpwalk) What am I missing?
-
I have added -D to snmpwalk to get debug information, I got: registered debug token v, 0 How do I access the debug info now?
-
With 5.8-685-gc71b9eb26 With the following /etc/snmpd.conf: # Listen only on local host agentAddress udp:localhost:161,udp6:[::1]:161 on Debian bullseye: no issue on Ubuntu eoan: no issue on one platform, the following issue on anotherwith the same configuration but at least snmpd does not crash anymore # snmpwalk -v 3 -u OpenNMS -l authPriv -a SHA -x AES -A "authpassphrase" -X "privpassphrase" 127.0.0.1 .1 Timeout: No Response from 127.0.0.1
-
snmpwalk has no dsebugging symbols, so gdb is useless. With the latest commit 5.8-660-g27f763d80, the new crash file is below.
-
The carsh file has already been uploaded in the first post.
-
Same issue for both commands.

snmpd does not answer remote get-request/get-next-request

With trapsess -r0 -Ci -v3 -u user -n "" -l authPriv -a SHA -A "authpassphrase" -x AES -X "encpassphrase" localhost, no SNMP_Cold_Start is received by Opennms, unlike with informsink:

Same issue with 5.8-621-gd1a6b1978.
-
Walking the MIBs with v3 crashes snmpd: double free or corruption (fasttop)
-
That's strange. It worked when I used it 3 days ago. - Have you tried with the same parameters, i.e SHA & AES? - in 5.8-613-ga02cd0c97, the createUser command must be declared in /var/net-snmp/snmpd.conf according to the snmp auto-generated comments - It is not necessary for me to declare the user also in snmptrapd.confbecause I use opennms which is already configured, so I do not use snmptrapd. - I confirm that opennms does not receive anything with trapsess

The solution is to remove host/data_access/swinst_rpm and it compiles fine!
-
Nice! You must have used a hidden ./configure option because I couldn't see anything allowing a complete list of all available mibs for the current host. I tried your list, but it fails to compile unfortuantely: host/data_access/swinst_rpm.c:78:15: warning: implicit declaration of function 'stat'; did you mean 'strcat'? [-Wimplicit-function-declaration] if (-1 == stat( pkg_directory, &stat_buf )) { ^~~~ strcat host/data_access/swinst_rpm.c: In function 'netsnmp_swinst_arch_load': host/data_access/swinst_rpm.c:96:5:...
-
Very helpful! Any reason why you don't use the following mibs? agent_mibs agentx notification snmpv3mibs target utilities Also, ./configure offers the possibility to use ucd_snmpmib: does it include all ucd_snmp/*?
-
hardware/sensors is fine if it can be interpreted/used by OpenNMS. ./configure --help does not show hardware/sensors Any other MIB not shown by ../configure --help that I should know about?
-
You need to - get 19.04 - upgrade all packages with 'apt update && apt upgrade' - install the apt release upgrader with 'apt install ubuntu-release-upgrader-core' - upgrade to the next development distribution with 'do-release-upgrade --devel-release --frontend=DistUpgradeViewNonInteractive' - reboot the server
-
Yes I'm sure. I use the develoment version 'eoan'. lm-sensors: Installed: 1:3.5.0-3ubuntu1
-
Multiple issues while walking the MIBs with SNMPv3
-
Cannot build with ucd-snmp/lmSensors MIB: ucd-snmp/lmSensors.c:950:11: error: unknown type name 'sensors_feature_data'
-
I was able to build v5.8-585-g4efee9f06 (without ucd-snmp/lmSensors MIB which creates an issue during the build) and the original issue about sending SNMPv2c TRAPS & INFORMs is gone.

I wish I could build a newer commit, but which one?
