Isn't the image published on DockerHub supposed to be equal to building it manually?

Please...This is just embarrassing. This comment might be off-topic, but it looks like our fellow Chinese user @jack9603301 need suggestions on how to use English in a proper manner. (Your current wording style can easily offend people.)
Here are my wording suggestions.

• Avoid double or tripple question marks.
• Avoid rhetorical questions.
• Use "Sorry", "Please", "Could you...", etc. for questions and requests.
• Avoid representing others if you are not entitled. For example, when *you* want some features, do not say "VyOS fans in China" want those features.

I can translated my points to Chinese if it can be better understood.

雖然你可能沒有意識到，但是你的英語行文很不禮貌，容易冒犯他人。以下是我的幾點建議：

• 避免使用多個問號。
• 避免反問他人。在中文語境下，反問也可以被認為是想吵架。
• 多用 "Sorry", "Please", "Could you..." 這種緩和語氣、表示禮貌的詞彙，特別是在提問或請求他人的時候。
• 不要輕易“代表”他人。

My take at the client config following the config I had:

I had made a custom image with wide-dhcpv6-client a week ago or so, this is the client config I was running for NA and PD, WAN is eth0 and gets assigned the NA address with the prefix assigned to eth1 with the address <prefix/sla-id>::1 (if ifid is not set it will assign EUI-64 address). The lifetime value was pulled from an example config and I left it as-is while testing.

@jack9603301 looking for a „service dhcpv6-server“ configuration which hands out the prefixes via ethernet so I can implement the client side.

@fetzerms Have you seen this problem with the fix mentioned above ? If not, I will close.

You want to fetch the repo before building; cf. the 'Generating the container section':

https://github.com/vyos/vyos-1x/pull/412

@runar just created this as I can not create a dev env without a phabricator entry. answer in 20 minutes :-)

What repository, and what errors? :)

I found abnormal behavior during label allocation. As I wrote above VyOS generate label for all prefixes presented in routing table. But when we have for example 5 connected routes (four /24 and one /32) on Egress LSR and we start mpls VyOS allocates labels for all routes and neighbor (downstream LSR) receives label=3 (implicit null). But if we have 2 connected routes (one /24 and one /32) then we start mpls, Egress LSR allocates labels for all routes (two in this case), but if we add on Egress LSR one, two or more new connected routes VyOS does not allocate label=3 for this routes and does not send Label Mapping Message to its neighbors for FECs related to new added routes. The software version is 1.3-rolling-202005160117

@c-po What did you want? Configuration of DHCPv6 PD in vyos?? Didn't you update the document? How do you configure it?? I don't quite understand!

I know that this does not cover all use cases but it is a PoC working for some users (not all of course). Next step would be adding this to ethernet based interfaces.

Great, dhcpv6-pd is finally coming true!

Thanks @c-po for the commit! I also want to point out the same thing as @tbr has mentioned... Some ISPs do not use PPPoE but plain ethernet w/ DHCP & DHCPv6-PD for address assignment, Google Fiber for example.

Hi, first of all, it's great that at least someone created the first work to add PD support. But for me this first commit is not usable, as my ISP provides internet via a plain ethernet interface. Moreover, I'm using VLANs on my internal network. So, best case, I will connect vyos directly to the modem on an ethernet interface, but my ISP does not use pppoe at all.

The run code could check the command name against a list of known "need sudo" commands and prepend it automagically so the command looks like normal but is auto-sudo'ed

Enjoy testing

From the Git commit:

After a new reboot, the DHCP nameservers were correctly added to resolv.conf and powerdns recursor.conf. I had system name-server and service dns forwarding name-server set to a static IP. But after deleting these two static nameserver nodes, the DHCP nameservers are missing from both resolv.conf and recursor.conf.

Hi, everyone.
As I understood from my lab VyOS generate label in cisco fashion (for all presented prefixes in routing table). And it is good as for me. But I think it is necessary to be able to filter the FEC for which labels will be generated (for example only for /32 routes, or only for particular routes).

@tbr Looking at this post, I don't think EdgeRouter has the capability...

@Azayaka If I'm correct, the EdgeOs can perfectly do multiple PD at the same time (at least request the prefixes), even on one interface.

Another problem of the EdgeRouter-style configuration is that only one PD is possible at a time. Cisco IOS uses the concept of dhcp pool and pd name-tag to deal with multiple PDs (a possible scenario: 2 PDs from 2 different ISPs for redundancy). Not sure if it can be supported by dhclient though.

I prefer the IOS style, and here is an example.

ipv6 dhcp pool POOL-v6
 dns-server 2001:4860:4860::8888

interface GigabitEthernet0/0/0
 ipv6 address autoconfig default
 ipv6 enable
 ipv6 nd ra suppress all
 ipv6 dhcp client pd ISP-name
 ipv6 virtual-reassembly in

interface Vlan1
 ipv6 enable
 ipv6 address ISP-name ::1/64
 ipv6 nd other-config-flag
 ipv6 nd ra interval 180
 ipv6 dhcp server POOL-v6 rapid-commit

After 2 release dhcp interface eth1 and one renew dhcp interface eth1, I now have 2 dhclients running, so there is a bug in the op-mode release/renew code.

4079 ?        Ss     0:00 /sbin/dhclient -4 -nw -cf /var/lib/dhcp/dhclient_eth1.conf -pf /var/lib/dhcp/dhclient_eth1.pid -lf /var/lib/dhcp/dhclient_eth1.leases eth1
4305 ?        Ss     0:00 /sbin/dhclient -q -nw -cf /var/lib/dhcp/dhclient_eth1.conf -pf /var/lib/dhcp/dhclient_eth1.pid -lf /var/lib/dhcp/dhclient_eth1.leases eth1

Passing passwords via command line arguments is very bad practice. Curl has a -u option, if passed just the user it prompts for the password on stdin. This can simply be passed via shell redirection.

@dmbaturin Maybe just anything that contains systemctl? Surely 100% of those will need it. But that also assumes anything called via /usr/lib/python3/dist-packages/vyos/util.py

Sometimes I wonder if we should just silently wrap every op mode command in sudo, at least those in the families other than show. It's hard to name a command that doesn't need sudo, and everyone (myself included!) has forgotten to add it at least once.

PR510 should add the necessary sudo
