wrong example in http://linux-ip.net/html/nat-dnat.html

SNAT example from 5.7 is:

is:
[root@real-server]# iptables -t nat -A POSTROUTING -s 192.168.100.17 -j SNAT --to-destination 205.254.211.17

should be:
[root@real-server]# iptables -t nat -A POSTROUTING -s 192.168.100.17 -j SNAT --to 205.254.211.17

Guides page claims Advanced Bash-Scripting Guide is maintained

The Advanced Bash-Scripting Guide is listed in the "Current / Maintained Guides" section of the Linux Documentation Project Guides page. This contradicts section 38.3. Where to Go For Help, which indicates that:

The author is no longer supporting or updating this document.

Update web site submission guidelines

I'd like to submit an improvement to the Serial HOWTO. But what's the current process?

The web site mailinfo page says "Remember that we prefer GitHub for new submits, followed by a message to [email protected]!" But it provides no link to GitHub or any further description of the process
The web site author guide doesn't mention this GitHub project.
I see there have been pull requests on this GitHub project. But they don't appear in the recent changes page, and looking at the recent Bash Prog change, it seems it has not resulted in an update to the corresponding page on the web site.

You might attract more contributions if the submission process was more transparent.

Improve HTML style CSS

I received recommendations to improve the HTML style

I've applied them here:

SSL/TLS Certs for ltdp.org expired

Sorry to post this here but namecheap wants me to create and account just to let you know the ssl certs are expired. Maybe consider changing to letsencrypt/certbot!? -thanks

Possibly inadvertent script in LDP/LDP/guide/docbook/linux-ip/scripts/copy-routing-table.sh

# - - - - - - - - - - -
  copy_routing_table () {
# - - - - - - - - - - -
#
# -- accepts one paramater:
#
#    $1:  table identifier for the routing table to create
#
  test "$#" -lt "1"     && return
  DTABLE=$1

  test "$#" -gt "1"     && STABLE="$2"
  test "$STABLE" = ""   && STABLE="main"

  ip route flush table $DTABLE
  ip route show table $STABLE | grep -Ev '^default' \
    | while read ROUTE ; do
      ip route add table $DTABLE $ROUTE
  done

}

It will not work when an equivalent route exists in the routing table, For example:

[root@k8s-master topo_build]# ip route show
1.1.1.1 proto 188 metric 20 
	nexthop via 10.0.0.2 dev tun1 weight 1 
	nexthop via 10.0.2.2 dev tun3 weight 1 
2.0.0.2 proto 188 metric 20 
	nexthop via 10.0.1.2 dev tun2 weight 1 
	nexthop via 10.0.3.2 dev tun4 weight 1

it will not work when we take routing in this way, It splits a route that occupies three rows into three routes...

[root@k8s-master topo_build]# ip route show | while read ROUTE; do echo [${i}]  $ROUTE; let i++; done
[] 1.1.1.1 proto 188 metric 20
[1] nexthop via 10.0.0.2 dev tun1 weight 1
[2] nexthop via 10.0.2.2 dev tun3 weight 1
[3] 2.0.0.2 proto 188 metric 20
[4] nexthop via 10.0.1.2 dev tun2 weight 1
[5] nexthop via 10.0.3.2 dev tun4 weight 1

linuxdoc.org unreachable

Domain linuxdoc.org is unreachable and all links not works anymore
But linuxdocs.org is available! is this domain related to tLDP officially?
May I make a PR and changes all links to main tldp.org or linuxdocs.org?

Broken link on http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-14.html

This link http://org.laol.net/lamug/beforever/bashtut.htm at the bottom of http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-14.html is broken.

Any hope to see tldp.org web pages updated?

It seems that the website and all its mirrors have been frozen for years, which is unfortunate because it is still among the main results after googling about Linux and its tools. Any hope to see the whole site revamped?

Broken URLs related to "test" and "drone"

result in

502 Bad Gateway
nginx

Is one able to fix this?

Unclear how issues in documents should be reported

Looking for a way to report issues in the Advanced Bash-Scripting Guide, I found no indication in the document. So I went looking for ways to report issues to the Linux Documentation Project.

Unfortunately, the Feedback link on LDP's website brings to the Linux Documentation Project Mailing Lists & Feedback page, which does not say a word about issue tracking.

Apologies for submitting this issue here - it does not look like the proper place to report it, but I could find no tracker other than this one.

DocBook 5?

I’m a huge fan of DocBook, but never expected to find another docs project built on it. So I’m feeling kind of gleeful to have found this repo. :)

Would there be an interest in converting to the (fully XML, rather than SGML) DocBook 5?

I believe I could help, if the desire is there.

SSL/TLS certificate is invalid on 1 server (50%)

❯ dig +short tldp.org A

152.19.134.151

These 2 IP addresses are not serving the same TLS certificate. One of them is invalid for the domain name tldp.org.
HSTS is on, so users are not allowed to work around this problem using http://.

Where is “The Linux Programmer’s Guide”?

I’m trying to find the source for “The Linux Programmer’s Guide”, as seen online at http://www.tldp.org/LDP/lpg/lpg.html.

I’ve looked around, but this project is huge, and I’m having trouble finding it.

(Does it even live here? The “About” of the above-linked document says it’s written in TeX…)
