Failed to parse group userif and firewall KAONMEDIA CG2200 CLARO #56

tolonuia · 2024-02-03T16:42:51Z

I have a router provided by Claro, its a KAONMEDIA CG2200, this is a GatewaySettings.bin. bcm2cfg is having issues reading firewall and userif sections.

bcm2utils-v0.9.7-win32> ./bcm2cfg info GatewaySettings.bin

edit: Im trying to activate telnet, so im running this:

bcm2cfg set GatewaySettings.bin userif.remote_acc_methods telnet

but then I get this error:

\bcm2utils-v0.9.7-win32>bcm2cfg set GatewaySettings.bin userif.remote_acc_methods telnet
failed to parse group userif
failed to parse group firewall
error: requested non-existing member 'remote_acc_methods'

The text was updated successfully, but these errors were encountered:

Your userif group uses a non-standard format. You can send me your GatewaySettings.bin file via email (joseph.c.lehner@gmail.com). Maybe I can work something out.

In response to #56.

The userif issue has been fixed. The firewall group still remains, but that is very low priority. Try this:

bcm2-utils-v0.9.7-8-g7092373-win32.zip

any help again will be greatly appreciated, still cant open telnet port 🙏

Forgot to mention: for this to work, you'll have to manually specify the profile (using -P cg2200):

$ bcm2cfg -P cg2200 get GatewaySettings.bin userif
failed to parse group firewall
userif = {
  http_user = "admin"
  http_pass = "admin"
  http_admin_user = "admin"
  http_admin_pass = "Cl@r0"
  http_local_user = "user"
  http_local_pass = "user"
  http_default_user = "admin"
  http_default_pass = "Cl@r0"
  remote_acc_methods = http
  remote_acc_user = "admin"
  remote_acc_pass = "admin"
  telnet_ipstacks = IP1 | IP2 | IP5
  ssh_ipstacks = IP1 | IP2 | IP5
  remote_acc_timeout = 600
  http_ipstacks = IP2 | IP5
  http_adv_ipstacks = IP3 | IP5
  http_seed = ""
  http_acl_hosts = {
    0x000 = 0A:E9:00:01:0A:E9:FF:FE:D8:E6:96:69:D8:E6:96:6E:C8:06:C0:09:C8:06:C0:0E
    0x018 = BE:94:0F:DC:BE:94:0F:DC:0A:DA:CB:71:0A:DA:CB:76:0A:1F:D2:11:0A:1F:D2:16
    0x030 = 0A:1F:DD:E9:0A:1F:DD:EE
  }
  http_idle_timeout = 600
  log_exceptions = yes
}

Note that a bug in the previous version prevents you from modifying the file. I've attached an update below:

Thank you so much for this amazing job you do. And Im sorry to bother you again, but when I try to set any of the other two remote access types I get error.

OPTIONS -

bcm2-utils-v0.9.7-8-g7092373-win32> ./bcm2cfg -P cg2200 type GatewaySettings.bin userif.remote_acc_methods
failed to parse group firewall
remote_acc_methods {
0x00000001 = telnet
0x00000002 = http
0x00000004 = ssh

WHAT IT IS RIGHT NOW -

bcm2-utils-v0.9.7-8-g7092373-win32> ./bcm2cfg -P cg2200 get GatewaySettings.bin userif.remote_acc_methods
failed to parse group firewall
userif.remote_acc_methods = http

WHAT I TRY TO SET IT TO -

bcm2-utils-v0.9.7-8-g7092373-win32> ./bcm2cfg -P cg2200 set GatewaySettings.bin userif.remote_acc_methods telnet
failed to parse group firewall
userif.remote_acc_methods = telnet
error: value exceeds maximum of target type

I cant seem to be able to modify the telnet port nor ssh (i tried too). Any advise? Or maybe I am doing something wrong?

Thank you for helping me.

PD: Before bothering you with my questions I tried googling answer but I couldn't find anything related to the topic.
