[Comm] вопрос по ipsec (связь теряется)

[Vitaly Gorshkov]

Ситуация:
1) комп
   AltMAster 2.4 + Backports + updates

ipsec.conf
config setup
        interfaces="ipsec1=ppp0"
        klipsdebug=none
        plutodebug=none
        plutoload=%search
        plutostart=%search

        ike=3des-md5-modp1536,3des-md5-modp1024,3des-sha-modp1536,3des-sha-modp1024
conn ru-prag-perehod
    auth=esp

    rightsubnet=172.16.0.0/24
    spi=0x300
    auto=start


# rpm -qa|grep swan
openswan-1.0.9-alt0.M24.1

------------------------------------------------
2) комп
Slackware
# uname -r
2.4.26
FreeSwan

ipsec.conf
config setup
         interfaces="ipsec1=eth0"
         klipsdebug=none
         plutodebug=none


conn %default
        keyingtries=0
        disablearrivalcheck=no
        auth=esp
        authby=rsasig
        compress=yes

        #auto=add
        auto=start
---------------------------------------------------

Периодически (раз в день), связь теряется - машины в другой сети не
пингуется,
лечится ipsec setup

----------------------------------------------------------------

вот отличия ipsec auto -status

а)когда висит соединение:
..
000 "ru-prag-perehod":   newest ISAKMP SA: #1; newest IPsec SA: #2; eroute owner: #2
..
000 #2: "ru-prag-perehod" STATE_QUICK_I2 (sent QI2, IPsec SA established); EVENT_SA_REPLACE in 27930s; newest IPSEC; eroute owner
000 #2: "ru-prag-perehod" esp.78c3b689@x.x.x.x esp.9983ff97@x.x.x.x comp.22da@x.x.x.x comp.a164@x.x.x.x tun.1002@x.x.x.x tun.1001@x.x.x.x
000 #1: "ru-prag-perehod" STATE_MAIN_I4 (ISAKMP SA established); EVENT_SA_REPLACE in 2993s; newest ISAKMP

б) ipsec setup restart
ipsec auto --status
...
000 "ru-prag-perehod":   newest ISAKMP SA: #32; newest IPsec SA: #26; eroute owner: #26
..
000 #31: "ru-prag-perehod" STATE_MAIN_R3 (sent MR3, ISAKMP SA established); EVENT_SA_REPLACE in 456s
