[07:58] . [11:27] I'm having a weird issue that some network guys might be able to figure [11:28] I have been trying to solve a problem relating to connection to my public IP which seems to just get blocked... [11:28] and have a server that i rent in DE which i am trying to use to debug this... [11:29] but i lost my connection to the DE server which have happened before and logged into the web interface to see if it is stil up [11:30] From the web interface in is up and i can start a virtual console from there... [11:31] now in the virtual console i can ping 8.8.8.8 and what not except for for public ip [11:32] and the same from my lappy which is on the other side of the public ip (expect for being able to react the DE server) [11:32] So i ran a traceroute (using mtr) on both... [11:34] From my public ip (which is 41.168.11.36) the in uses 41.168.11.1 and then 41.160.0.245 which then looses the connection some 15 hops later... [11:35] but from the DE server it reaches 41.160.0.244 (not 245) after about 15 hops with the next hop being undetermined... [11:37] so it seem that some arp (or other) issue exists on the 41.160.0.0/24 network? [12:10] oh that should be routing issue, but then i now also spotted that there are a few addresses in the route that differ but are in the same subset (assuming /32) [16:10] chesedo, are you trying to access a local machine from outside the public ip? === Cryterion_ is now known as Cryterion [18:03] . [18:44] Cryterion: the public ip has port forwards to a local machine yes - which is the original issue i'm trying to sort - but then the complete connection to the public ip (pings) went down as described above [18:46] or the shh connection from me (behind the public ip) to the DE server so that i can fix the original issue [18:50] DE server is the one at 41.168.11.36? [18:51] no that's my public ip [18:51] DE is 185.172.59.164 [18:52] ping and ssh went through fine, although I can't login as don't have user acc [18:53] that the thing, using a third ip I can get to both [18:53] but they cannot get to each other [18:54] I'm reading this as, you can't connect from behind the 41 ip? [18:54] well i can get to the DE server via a web interface of the provider [18:54] but not ssh [18:55] yes, and using the web interface i cannot get to 41 either [18:55] not even pings [18:55] that is a virtual terminal in the web ui [18:56] does the server have any ip banning configured, I know mines setup to ban 24hrs on ssh fail [18:57] no, but the providers might [18:58] i did an nmap scan from the DE to the 41 just before it went down [18:58] well, it went down during... [18:58] can you get into terminal via the web based ui [18:59] yes [18:59] it is just slow [19:00] chk if you have iptables running [19:00] you'll need to be root [19:01] waiting for the ui... [19:01] sudo iptables - that will let us know if it's installed [19:02] yip v1.6.0 [19:02] sudo service iptables stop [19:02] that'll stop the ip banning, try ssh afterwards [19:03] I hope, just trying things out to help [19:04] hmm, 'failed to stop.... unit iptables.servie not loaded' [19:04] hmm [19:04] nat table is empty [19:04] now checking filters... [19:05] ok so if that's not running, gonna check a few things, brb [19:06] filter table is empty too [19:07] other one is FailToBan [19:08] hmm, the DE server is only a mail server with nginx for webmail [19:09] check in /etc/ if you have a fail2ban dir [19:09] ...modoboa to be specific [19:10] I used iRedMail, so mines different [19:10] but looking it up [19:10] nope, no fail2ban dir [19:12] I'm trying to find out which one your mail system is using modoboa looks like a python based mail server [19:12] yes it is py based [19:16] chesedo, join #modoboa [19:17] ty Cryterion did so... [19:19] I'm transfering our chat there, that seems to right channel for it, if we can't come right together, someone else there could help [19:19] yip... [19:20] although i think this might have happened in the past - i just took it as the server being down - so am thinking that it might also be a service provider located... [19:21] might have to email my isp tomorrow [19:23] btw, ty Cryterion for the help so far [19:24] np
