lldpd not available for 16.x

[orneh24]

Hi,
I was hoping to add lldpd to a TCL install, but could only find it available for 14.x:
http://tinycorelinux.net/14.x/x86_64/tcz/src/lldpd/

Will the lldpd app be made available for 16.x builds? Or is it possible to simply install the 14.x version, on top of a 16.x build?

[Rich]

Hi orneh24
Welcome to the forum.

Try downloading:
http://tinycorelinux.net/14.x/x86_64/tcz/lldpd.tcz
http://tinycorelinux.net/14.x/x86_64/tcz/lldpd.tcz.dep

Then:

Code: [Select]

tce-load -w libcap readline libxml2
tce-load -i lldpdand see if it works.

If not, download the files at:
http://tinycorelinux.net/14.x/x86_64/tcz/src/lldpd/
into their own directory. Then:

Code: [Select]

chmod 775 lldpd.build
./lldpd.buildThe first command makes  lldpd.build  executable.
The second command runs  lldpd.build.
When  lldpd.build  completes, you should have a complete set of
files for the  lldpd  extension.

[orneh24]

Thanks Rich 
Will give it a go right away.
Quick follow-up; would the same process be applicable for the net-snmp package from 15.x?
http://tinycorelinux.net/15.x/x86_64/tcz/src/net-snmp/

[Rich]

Hi orneh24
net-snmp  is available in TC16 x86_64:
http://tinycorelinux.net/15.x/x86_64/tcz/net-snmp.tcz.info

[orneh24]

Then:

Code: [Select]

tce-load -w libcap readline libxml2
tce-load -i lldpdand see if it works.

Looks like it's almost there;

Will take a look at the build method, to see if that works (although let me know if you spot anything incorrect in what I did above)

[Rich]

Hi orneh24
I've never used lldpd, but it appears like you may need to run it as root:

Code: [Select]

sudo su
lldpcli show neighbors

[orneh24]

Running as root returned the same errors - so I tried the build method instead (should note, I've never compiled anything myself before, so this is somewhat uncharted territory for me)

The build script seems to have completed successfully:

But seems to be a problem with either creating the socket or a _lldpd user;

Code: [Select]

tc@lldpdboxtest:~/ll$ lldpcli
2025-08-22T05:26:53 [WARN/control] unable to connect to socket /var/run/lldpd.socket: No such file or directory

Will try to dig a bit further and see if I can make it work

[Rich]

Hi orneh24
It looks like you need to create an _lldpd  user and group.
Try this:

Code: [Select]

sudo su
addgroup _lldpd
adduser -H -S -s /bin/sh -G _lldpd -D _lldpd
echo -e "_lldpd\tALL=NOPASSWD: ALL" >> /etc/sudoers
exit
Then see if this command behaves any better:

Code: [Select]

sudo lldpd -dddd
If it does, then:

Code: [Select]

echo "etc/group" >> /opt/.filetool.lst
echo "etc/gshadow" >> /opt/.filetool.lst
echo "etc/passwd" >> /opt/.filetool.lst
echo "etc/shadow" >> /opt/.filetool.lst
echo "etc/sudoers" >> /opt/.filetool.lst
filetool.sh -b

[orneh24]

Thanks Rich, appreciate the help.
Will try out the commands later tonight.

[orneh24]

Allright, so after adding the group and user, lldpd successfully starts

I believe the only thing missing now, is the init.d/lldpd and making the lldpd package installation persistent (or rather, what would be the correct way, of making it persistent after building it locally)?

[Rich]

Hi orneh24

... I believe the only thing missing now, is the init.d/lldpd ...

I'll look into that.

... and making the lldpd package installation persistent (or rather, what would be the correct way, of making it persistent after building it locally)?

I'm assuming you used the build script, so copy lldpd.tcz, lldpd.tcz.dep, and lldpd.tcz.md5.txt
to your  tce/optional directory.

Make sure  lldpd.tcz  is listed in  onboot.lst.

If you followed these instructions:

...

Code: [Select]

echo "etc/group" >> /opt/.filetool.lst
echo "etc/gshadow" >> /opt/.filetool.lst
echo "etc/passwd" >> /opt/.filetool.lst
echo "etc/shadow" >> /opt/.filetool.lst
echo "etc/sudoers" >> /opt/.filetool.lst
filetool.sh -b

then the added  _lldpd  user and group will survive a reboot.

[orneh24]

ref. persistency - copied lldpd.tcz, .tcz.dep and .tcz.md5.txt to /mnt/sda1/tce/optional and added lldpd to onboot.lst.

Currently trying to understand how TCL handles init.d - are the files in /usr/local/etc/init.d/ just symlinks to /tmp/tcloop/ ? I tried taking a look at the Wiki, but couldn't quite find the info.

Code: [Select]

tc@nginxsnmptcl:/usr/local/etc/init.d$ ll

lrwxrwxrwx    1 root     root            42 Aug 23 00:09 fuse -> /tmp/tcloop/fuse/usr/local/etc/init.d/fuse

lrwxrwxrwx    1 root     root            48 Aug 23 00:09 openssh -> /tmp/tcloop/openssh/usr/local/etc/init.d/openssh

Edit; sorry Rich, didn't see your reply before posting this one. Yes, I did indeed also add the group, gshadow, passwd, shadow and sudoers file to .filetool.lst.

[Rich]

Hi orneh24

... are the files in /usr/local/etc/init.d/ just symlinks to /tmp/tcloop/ ? ...

Yes, they are.

Extensions are read-only file systems that get mounted under /tmp/tcloop/.
Their contents then get symlinked into the system directories.

[patrikg]

Hi @orneh24.
If you want, you can also make a script that will add the user and group when the user installing the extension.
Se this wiki page how to do it.

[Rich]

Hi orneh24
Sorry for the delay. I started by trying to modify an existing
init.d/lldpd  script from another distro. It proved to be too
complicated, so I adapted our  init.d/dbus  script:

Code: [Select]

#!/bin/sh

NAME=lldpd
DAEMON="/usr/local/sbin/$NAME"
DAEMON_ARGS=""


start()
{
start-stop-daemon -S -x "$DAEMON" -- "$DAEMON_ARGS"
}

stop()
{
start-stop-daemon -K -x "$DAEMON" 2>/dev/null
rm -rf /var/run/"$NAME"*
}



status()
{
if [ -e /var/run/"$NAME".pid ]; then
echo -e "\n$NAME is running.\n"
exit 0
else
echo -e "\n$NAME is not running.\n"
exit 1
fi
}

case $1 in
start) start
;;
stop) stop
;;
status) status
;;
restart) stop; start
;;
*) echo -e "\n$0 [start|stop|restart|status]\n"
;;
esac
Under  stop() , I've included a command to remove all lldpd
files and directories in case lldpd does not clean up after
itself when stopped:

Code: [Select]
